He began his career in the Imperial German Navy before World War I. In 1918, he was commanding UB-68 when she was sunk by British forces. Dönitz was taken prisoner. While in a prisoner of war camp, he formulated what he later called Rudeltaktik ("pack tactic", commonly called "wolfpack").
At the start of World War II, he was the senior submarine officer in the Kriegsmarine, known as Befehlshaber der Unterseeboote (BdU). In January 1943, Dönitz achieved the rank of Großadmiral (grand admiral) and replaced Grand Admiral Erich Raeder as Commander-in-Chief of the Navy. Dönitz was the main enemy of Allied naval forces in the Battle of the Atlantic. From 1939–1943 the U-boats fought effectively but lost the initiative from May 1943. Dönitz ordered his submarines into battle until 1945 to relieve the pressure on other branches of the Wehrmacht (Nazi German Armed Force). 648 U-boats were lost—429 with no survivors. A further 215 were lost on their first patrol. Around 30,000 of the 40,000 men to serve on U-boats perished.
On 30 April 1945, after the death of Adolf Hitler and in accordance with Hitler's last will and testament, Dönitz was named Hitler's successor as head of state, with the title of President of Germany and Supreme Commander of the Armed Forces. On 7 May 1945, he ordered Alfred Jodl, Chief of Operations Staff of the OKW, to sign the German instruments of surrender in Reims, France. Dönitz remained as head of the Flensburg Government, as it became known, until it was dissolved by the Allied powers on 23 May.
Dönitz was a dedicated Nazi and supporter of Hitler and he held anti-Semitic beliefs. Following the war, Dönitz was indicted as a major war criminal at the Nuremberg Trials on three counts: conspiracy to commit crimes against peace, war crimes, and crimes against humanity; planning, initiating, and waging wars of aggression; and crimes against the laws of war. He was found not guilty of committing crimes against humanity, but guilty of committing crimes against peace and war crimes against the laws of war. He was sentenced to ten years' imprisonment; after his release, he lived in a village near Hamburg until his death in 1980.
Early life and career
On 27 September 1913, Dönitz was commissioned as a Leutnant zur See (acting sub-lieutenant). When World War I began, he served on the light cruiser SMS Breslau in the Mediterranean Sea. In August 1914, the Breslau and the battlecruiser SMS Goeben were sold to the Ottoman Navy; the ships were renamed the Midilli and the Yavuz Sultan Selim, respectively. They began operating out of Constantinople, under Rear Admiral Wilhelm Souchon, engaging Russian forces in the Black Sea. On 22 March 1916, Dönitz was promoted to Oberleutnant zur See. He requested a transfer to the submarine forces, which became effective on 1 October 1916. He attended the submariner's school at Flensburg–Mürwik and passed out on 3 January 1917. He served as watch officer on U-39, and from February 1917 onward as commander of UC-25. On 2 July 1918, he became commander of UB-68, operating in the Mediterranean. On 4 October, after suffering technical difficulties, Dönitz was forced to surface and scuttled his boat. He was captured by the British and remained a prisoner of war until 1919, in 1920 he returned to Germany.
On 27 May 1916, Dönitz married a nurse named Ingeborg Weber (1894–1962), the daughter of German general Erich Weber (1860–1933). They had three children whom they raised as Protestant Christians: daughter Ursula (1917–1990) and sons Klaus (1920–1944) and Peter (1922–1943). Both of Dönitz's sons were killed during the Second World War. Peter was killed on 19 May 1943 when U-954 was sunk in the North Atlantic with all hands.
Hitler had issued a policy stating that if a senior officer such as Dönitz lost a son in battle and had other sons in the military, the latter could withdraw from combat and return to civilian life. After Peter's death Klaus was forbidden to have any combat role and was allowed to leave the military to begin studying to become a naval doctor. He returned to sea and was killed on 13 May 1944; he had persuaded his friends to let him go on the E-boat S-141 for a raid on Selsey on his 24th birthday. The boat was sunk by the French destroyer La Combattante.
He continued his naval career in the naval arm of the Weimar Republic's armed forces. On 10 January 1921, he became a Kapitänleutnant (lieutenant) in the new German navy (Vorläufige Reichsmarine). Dönitz commanded torpedo boats, becoming a Korvettenkapitän (lieutenant-commander) on 1 November 1928. On 1 September 1933, he became a Fregattenkapitän (commander) and, in 1934, was put in command of the cruiser Emden, the ship on which cadets and midshipmen took a year-long world cruise as training.
In 1935, the Reichsmarine was renamed Kriegsmarine. Germany was prohibited by the Treaty of Versailles from possessing a submarine fleet. The Anglo-German Naval Agreement of 1935 allowed submarines and he was placed in command of the U-boat flotilla Weddigen, which comprised three boats; U-7; U-8 and; U-9. On 1 September 1935, he was promoted to Kapitän zur See (naval captain).
Dönitz opposed Raeder's views that surface ships should be given priority in the Kriegsmarine during the war, but in 1935 Dönitz doubted U-boat suitability in a naval trade war on account of their slow speed. This phenomenal contrast with Dönitz's wartime policy is explained in the 1935 Anglo-German Naval Agreement. The accord was viewed by the navy with optimism, Dönitz included. He remarked, "Britain, in the circumstances, could not possibly be included in the number of potential enemies." The statement, made after June 1935, was uttered at a time when the naval staff were sure France and the Soviet Union were likely to be Germany's only enemies. Dönitz's statement was partially correct. Britain was not foreseen as an immediate enemy, but the navy still held onto a cadre of imperial officers, which along with its Nazi-instigated intake, understood war would be certain in the distant future, perhaps not until the mid–1940s.
Dönitz came to recognise the need for more of these vessels. Only 26 were in commission or under construction that summer. In the time before his command wth submarines, he perfected the group tactics that first appealed to him in 1917. At this time Dönitz first expressed his procurement policies. His preference for the submarine fleet was in the production of large numbers of small craft. In contrast to other warships, the fighting power of the U-boat in his opinion did not fluctuate in relation to its size for the torpedo, not the gun, was the machine's main weapon. Dönitz had a tendency to be critical of larger submarines and listed a number of disadvantages in their production, operation and tactical use. Dönitz recommended the Type VII submarine as the ideal submarine. The boat was reliable and had a range of 6,200 miles. Modifications lengthened this to 8,700 miles.
Dönitz revived Hermann Bauer's idea of grouping several submarines together into a Rudeltaktik ("pack tactic", commonly called "wolfpack") to overwhelm a merchant convoy's escorts. Implementation of wolfpacks had been difficult in World War I owing to the limitations of available radios. In the interwar years, Germany had developed ultrahigh frequency transmitters, while the Enigma cipher machine was believed to have made communications secure. A 1922 paper written by Kapitäinleutnant Wessner of the Wehrabteilung (Defence Ministry) pointed to the success of surface attacks at night and the need to coordinate operations with multiple boats to defeat the escorts. Dönitz knew of the paper and improved the ideas suggested by Wassner. This tactic had the added advantage that a submarine on the surface was undetectable by Asdic. Dönitz claimed after the war he would not allow his service to be intimidated by British disclosures about Asdic and the course of the war had proven him right. In reality, Dönitz harboured fears stretching back to 1937 that the new technology would render the U-boat impotent. Dönitz published his ideas on night attacks in January 1939 in a booklet called Die U-Bootwaffe which apparently went unnoticed by the British. The Royal Navy's overconfidence in Asdic encouraged the Admiraly to suppose it could deal with submarines whatever strategy they adopted—in this they proven wrong; submarines were difficult to locate and destroy under operational conditions.
In 1939 he expressed his belief that he could win the war with 300 vessels. The Nazi leadership's rearmament priorities were fundamentally geared to land and aerial warfare. From 1933–36, the navy was granted only 13 percent of total armament expenditure. The production of U-boats, despite the existing Z Plan, remained low. In 1935 shipyards produced 14 submarines, 21 in 1936, one 1937. In 1938 nine were commissioned and in 1939 18 U-boats were built. Dönitz's vision may have been misguided. The British had planned for contingency construction programmes for the summer, 1939. At least 78 small escorts and a crash construction programme of "Whale catchers" had been invoked. The British, according to one historian, had taken all the sensible steps necessary to deal with the U-boat menace as it existed in 1939 and were well placed to deal with large numbers of submarines, prior to events in 1940.
World War II
On 1 September 1939, Germany invaded Poland. Britain and France declared war on Germany, and World War II began. On Sunday 3rd September, Dönitz chaired a conference at Wilhelmshaven. At 11:15 am the British Admiralty sent out a signal "Total Germany". B-Dienst intercepted the message and it was promptly reported to Dönitz. Dönitz paced around the room and his staff purportedly heard him repeatedly say, "My God! So it's war with England again!"
Dönitz abandoned the conference to return within the hour a far more composed man. He announced to his officers, "we know our enemy. We have today the weapon and a leadership that can face up to this enemy. The war will last a long time; but if each does his duty we will win." Dönitz had only 57 boats; of those, 27 were capable of reaching the Atlantic ocean from their German bases. A small building program was already underway but the number of U-boats did not rise noticeably until the autumn of 1941.
Dönitz's first major action was the cover up of the sinking of the British passenger liner Athenia later the same day. Acutely sensitive to international opinion and relations with the United States, the death of hundreds of civilians was damaging. Dönitz suppressed the truth that the ship was sunk by a German submarine. He accepted the commander's explanation that he genuinely believed the ship was armed. Dönitz ordered the engagement to be struck from the submarine's logbook. Dönitz did not admit the cover up until 1946.
Hitler's original orders to wage war only in accordance with the Prize Regulations, were not issued in any altruistic spirit but in the belief hostilities with the Western Allies would be brief. On 23 September 1939, Hitler, on the recommendation of Admiral Raeder, approved that all merchant ships making use of their wireless on being stopped by U-boats should be sunk or captured. This German order marked a considerable step towards unrestricted warfare. Four days later enforcement of Prize Regulations in the North Sea was withdrawn; and on the 2 October complete freedom was given to attack darkened ships encountered off the British and French coasts. Two days later the Prize Regulations were cancelled in waters extending as far as 15° West, and on the 17 October the German Naval Staff gave U-boats permission to attack without warning all ships identified as hostile. The zone where darkened ships could be attacked with complete freedom was extended to 20° West on the 19th of October. Practically the only restrictions now placed on U-boats concerned attacks on passenger liners and, on the 17 November, they too were allowed to be attacked without warning if clearly identifiable as hostile.
Although the phrase was not used, by November 1939 the BdU was practicing unrestricted submarine warfare. Neutral shipping was warned by the Germans against entering the zone which, by American neutrality legislation, was forbidden to American shipping, and against steaming without lights, zigzagging or taking any defensive precautions. The complete practice of unrestricted warfare was not enforced for fear of antagonising neutral powers, particularly the Americans. Admirals Raeder and Dönitz and the German Naval Staff had always wished and intended to introduce unrestricted warfare as rapidly as Hitler could be persuaded to accept the possible consequences.
Dönitz and Raeder accepted the death of the Z Plan upon the outbreak of war. The U-boat programme would be the only portion of it to survive 1939. Both men lobbied Hitler to increase the planned production of submarines to at least 29 per month. The immediate obstacle to the proposals was Hermann Göring, head of the Four Year Plan, commander-in-chief of the Luftwaffe and future successor to Hitler. Göring would not acquiesce and in March 1940 Raeder was forced to drop the figure from 29 to 25, but even that plan proved illusory. In the first half of 1940, two boats were delivered, increased to six in the final half of the year. In 1941 the deliveries increased to 13 to June, and then 20 to December. It was not until late 1941 the number of vessels began to increase quickly.
Commander of the submarine fleet
On 1 October 1939, Dönitz became a Konteradmiral (rear admiral) and "Commander of the Submarines" (Befehlshaber der Unterseeboote, BdU). For the first part of the war, despite disagreements with Raeder where best to deploy his men, Dönitz was given considerable operational freedom for his junior rank.
From September–December 1939 U-boats sank 221 ships for 755, 237 gross tons, at the cost of nine U-Boats. Only 47 merchant ships were sunk in the North Atlantic, a tonnage of 249,195. Dönitz had difficulty in organising Wolfpack operations in 1939. A number of his submarines were lost en route to the Atlantic, through either the North Sea and heavily defended English Channel. Torpedo failures plagued commanders during convoy attacks. Along with successes against single ships, Dönitz authorised the abandonment of pack attacks in the autumn. The Norwegian Campaign amplified the defects. Dönitz wrote in May 1940, "I doubt whether men have ever had to rely on such a useless weapon." He ordered the removal of magnetic pistols in favour of contact fuses and their faulty depth control systems.
Dönitz was encouraged in operations against warships by the sinking of aircraft carrier Courageous. On 28 September 1939 he said, "it is not true Britain possesses the means to eliminate the U-boat menace." The first specific operation authorised by Dönitz was Günther Prien's attack on Scapa Flow which sank a battleship. The attack became a propaganda success though Prien purportedly was unenthusiastic about being used that way. Stephen Roskill wrote, "It is now known that this operation was planned with great care by Admiral Dönitz, who was correctly informed of the weak state of the defences of the eastern entrances. Full credit must also be given to Lieutenant Prien for the nerve and determination with which he put Dönitz's plan into execution."
In May 1940, 101 ships were sunk—but only nine in the Atlantic—followed by 140 in June; 53 of them in the Atlantic for a total of 585,496 grt that month. The first six months in 1940 cost Dönitz 15 U-Boats. Until mid-1940 there remained a chronic problem with the reliability of the G7e torpedo. As the battles of Norway and Western Europe raged, the Luftwaffe sank more ships than the U-boats. In May 1940, German aircraft sank 48 ships (158 348 grt), three times that of German submarines. The Allied evacuations from western Europe and Scandinavia in June 1940 attracted Allied warships in large numbers, leaving many of the Atlantic conoys travelling through the Western Approaches unprotected. From June 1940, the German submarines began to exact a heavy toll. In the same month, the Luftwaffe sank just 22 ships (195,193 grt) in a reversal of the previous months.
Germany's defeat of Norway gave the U-boats new bases much nearer to their main area of operations off the Western Approaches. The U-boats operated in groups or 'wolf packs' which were coordinated by radio from land. With the fall of France, Germany acquired U-boat bases at Lorient, Brest, St Nazaire, and La Pallice/La Rochelle and Bordeaux. This extended the range of Type VIIs. Regardless, the war with Britain continued. The admiral remained sceptical of Operation Sea Lion, a planned invasion and expected a long war. The destruction of seaborne trade became German strategy against Britain after the defeat of the Luftwaffe in the Battle of Britain. Hitler was content with the The Blitz and cutting off Britain's imports. Dönitz gained importance as the prospect of a quick victory faded. Dönitz concentrated groups of U-boats against the convoys and had them attack on the surface at night. In addition the Germans were helped by Italian submarines which in early 1941 actually surpassed the number of German U-boats. Having failed to persuade the Nazi leadership to prioritise U-boat construction, a task made more difficult by military victories in 1940 which convinced most Britain would give up the struggle, Dönitz welcomed the deployment of 26 Italian submarines to his force. Dönitz complemented Italian bravery and daring, but was critical of their training and submarine designs. Dönitz remarked they lacked the necessary toughness and discipline and consequently were "of no great assistance to us in the Atlantic."
The establishment of German bases on the French Atlantic coast allowed for the prospect of aerial support. Small numbers of German aircraft, such as the long–range Focke-Wulf Fw 200, sank a large number of ships in the Atlantic in the last quarter of 1940. In the long term, Göring proved an insurmountable problem in effecting cooperation between the navy and the Luftwaffe. In early 1941, while Göring was on leave, Dönitz approached Hitler and secured from him a single bomber/maritime patrol unit for navy. Göring succeeded in overturning this decision and both Dönitz and Raeder were forced to settle for a specialist maritime air command under Luftwaffe control. Poorly supplied, Fliegerführer Atlantik achieved modest success in 1941, but thereafter failed to have an impact as British counter-measures evolved. Cooperation between the Kriegsmarine and Luftwaffe remained dysfunactional to the war's end. Göring and his unassailable position at the Reichsluftfahrtministerium (Air Ministry) prevented all but limited collaboration.
The U-boat fleet's successes in 1940 and early 1941 were spearheaded by a small number of highly trained and experienced pre-war commanders. Otto Kretschmer, Joachim Schepke, Günther Prien were the most famous, but others included Hans Jenisch, Victor Oehrn, Engelbert Endrass, Herbert Schulze and Hans-Rudolf Rösing. Although skilled and with impecceable judgement, the shipping lanes they decended upon were poorly defended. The U-boat force did not escape unscathed. Within the space of several days in March 1941, Prien and Schepke were dead and Kretschmer was a prisoner. All of them fell in battle with a convoy system. The number of boats in the Atlantic remained low. Six fewer existed in May 1940 than in September 1939. In January 1941 there were just six on station in the Atlantic—the lowest during the war, while still suffering from unreliable torpedoes. Dönitz insisted that operations continue while "the smallest prospect of hits" remained.
For his part, Dönitz was involved in the daily operations of his boats and all the major operational level decisions. His assistant, Eberhard Godt, was left to manage daily operations as the war continued. Dönitz was debriefed personally by his captains which helped establish a rapport between leader and led. Dönitz neglected nothing that would make the bond firmer. Often there would be a distribution of medals or awards. As an ex-submariner, Dönitz did not like to contemplate the thought of a man who had done well, heading out to sea, perhaps never to return, without being rewarded or receiving recognition. Dönitz acknowledged where decorations were concerned there was no red tape and that awards were "psychologically important."
Intelligence played an important role in the Battle of the Atlantic. In general, BdU intelligence was poor. Counter-intelligence was not much better. At the height of the battle in mid-1943 some 2,000 signals were sent from the 110 U-Boats at sea. Radio traffic compromised his ciphers by giving the Allies more messages to work with. Furthermore, replies from the boats enabled the Allies to use direction finding (HF/DF, called "Huff-Duff") to locate a U-boat using its radio, track it and attack it. The over-centralised command structure of BdU and its insistence on micro-managing every aspect of U-boat operations with endless signals provided the Allied navies with enormous intelligence. The enormous "paper chase" [cross-referencing of materials] operations pursued by Allied intelligence agencies was not thought possible by BdU. The Germans did not suspect the Allies had identified the codes broken by B-Dienst. Conversley, when Dönitz suspected the enemy had penetrated his own communications BdU's response was to suspect internal sabotage and reduce the number of the staff officers to the most reliable, exacerbating the problem of over-centralisation. In contrast to the Allies, the Wehrmacht was suspicious of civilian scientific advisors and generally distrusted outsiders. The Germans were never as open to new ideas or thinking of war in intelligence terms. According to one analyst BdU "lacked imagination and intellectual daring" in the naval war. These Allied advantages failed to avert heavy losses in the June 1940–May 1941 period, known to U-Boat crews as the "First Happy Time." In June 1941, 68 ships were sunk in the North Atlantic (318,740 grt) at a cost of four U-Boats, but the German submarines would not eclipse that number for the remainder of the year. Just 10 transports were sunk in November and December 1941.
On 7 May 1941, the Royal Navy captured the German Arctic meteorological vessel München and took its Enigma machine intact, this allowed the Royal Navy to decode U-boat radio communications in June 1941. Two days later the capture of U-110 was an intelligence coup for the British. The settings for high-level "officer-only" signals, "short-signals" (Kurzsignale) and codes standardising messages to defeat HF/DF fixes by sheer speed were found. Only the Hydra settings for May were missing. The papers were the only stores destroyed by the crew. The capture on 28 June of another weather ship, Lauenburg, enabled British decryption operations to read radio traffic in July 1941. Beginning in August 1941, Bletchley Park operatives could decrypt signals between Dönitz and his U-boats at sea without any restriction. The capture of the U-110 allowed the Admiralty to identify individual boats, their commanders, operational readiness, damage reports, location, type, speed, endurance from working up in the Baltic to Atlantic patrols. On 1 February 1942, the Germans had introduced the M4 cipher machine, which secured communications until it was cracked in December 1942. Even so, the U-boats achieved their best success against the convoys in March 1943, due to an increase in U-boat numbers, and the protection of the shipping lines was in jeopardy. Due to the cracked M4 and the use of radar, the allies began to send air and surface reinforcements to convoys under threat. The shipping lines were secured, which came as a great surprise to Dönitz. The lack of intelligence and increased numbers of U-boats contributed enormously to Allied losses that year.
Signals security aroused Dönitz's suspicions during the war. On 12 January 1942 German supply submarine U-459 arrived 800 nautical miles west of Freetown, well clear of convoy lanes. It was scheduled to rendezvous with an Italian submarine, until intercepted by a warship. The German captain's report coincided with reports of a decrease in sightings and a period of tension between Dönitz and Raeder. The number of U-boats in the Atlantic, by logic, should have increased, not lowered the number of sightings and the reasons for this made Dönitz uneasy. Despite several investigations, the conclusions of the BdU staff was that Engima was impenetrable. His signals officer responded to the U-459 incident with answers ranging from coincidence, direction finding to Italian treachery. General Erich Fellgiebel, Chief Signal Officer of Army High Command and of Supreme Command of Armed Forces (Chef des Heeresnachrichtenwesens), apparently concurred with Dönitz. He concluded that there was "convincing evidence" that, after an "exhaustive investigation" that the Alliex codebreakers had been reading high level communications. Other departments in the navy downplayed or dismissed these concerns. They vaguely implied "some components" of Enigma had been compromised, but there was "no real basis for acute anxiety as regards any compromise of operational security."
Following Hitler's declaration of war on the United States on 11 December 1941, Dönitz implemented Operation Drumbeat (Unternehmen Paukenschlag). The entry of the United States benefited German submarines in the short term. Dönitz intended to strike close to shore in American and Canadian waters and prevent the convoys—the most effective anti–U-boat system—from ever forming. Dönitz was determined to take advantage of Canadian and American unpreparedness before the situation changed.
The problem inhibiting Dönitz's plan was a lack of boats. On paper he had 259. In January 1942, 99 were undergoing sea trials, 59 were assigned to training flotillas. This left 101 on war operations. 35 of these were under repair in port leaving 66 operational. 18 were low on fuel and returning to base, 23 were en route to areas where fuel and torpedoes needed to be conserved, and one was heading to the Mediterranean. On 1 January Dönitz had a fighting strength of 25—16 in the Atlantic (six near to Iceland on "Norwegian operations"), three in the Arctic Ocean, three in the Mediterranean and three operating west of Gibraltar. Dönitz was severely limited to what he could accomplish in American waters in an initial offensive.
From 13 January 1942, Dönitz planned to begin a surprise offensive from the Gulf of Saint Lawrence to the Cape Hatteras. Unknown to him, ULTRA had read his Enigma signals and knew the position, size and intentions of his boats down to the date the operation was scheduled to begin. The attacks, when they came, were not a surprise. Of the 12 U-boats that began the offensive from the Grand Banks southward, just two survived the war. The operation began the Battle of the St. Lawrence, a series of battles which lasted into 1944. Along with conventional U-boat operations Dönitz authorised clandestine activities in Canadian waters, ranging from spying, mine-laying and recovery of German prisoners of war. All of these things tied down Canadian military power and imposed industrial, fiscal a psychological and tactical cost. The imputinity with which U-boats carried out these operations in Canadian waters into 1944 provided a propaganda effect. Dönitz also wished to extract information from captured submariners concerning the loss of their boat, capture and Allied tactics. One of these operations was the well-known Operation Kiebitz to rescue Otto Kretschmer.
Even with operational problems great success was achieved in American waters. January to July 1942 Dönitz was able to attack un-escorted ships off the United States East Coast and in the Caribbean Sea. U-boats sank more ships and tonnage than at any other time in the war. A convoy system was introduced to protect the shipping and Dönitz shifted his U-boats back to the North Atlantic. The period, known in the U-Boat arm as the "Second Happy Time", represented one of the greatest naval disasters of all time, and largest defeat suffered by American sea power. The success was achieved with only five U-Boats initially which sank 397 ships in waters protected by the United States Navy with an additional 23 sunk at the Panama Sea Frontier. Dönitz put the successes down to the American failure to initialise a blackout along the East Coast of the United States and ship captains insistence on following peace-time procedures.
By the time improved American air and naval defences had driven German submarines from American shores, 5,000 Allied sailors had been killed for negligible losses in U-Boats. Dönitz ordered simultaneous operations in the Caribbean Sea. The ensuing Battle of the Caribbean resulted in immediate dividends for U-boats. In a short time, at least 100 transports had been destroyed or sunk. The sinkings damaged inter-island trade and had an impact upon Britain and the United States. Operation Neuland was among the most damaging naval campaigns in the region. Oil refinery production in region declined while the tanker fleet suffered losses of up to ten percent within twenty-four hours. Dönitz could not hope to sink more ships than American industry were to build. He targeted the tanker fleet in the Caribbean and Gulf of Mexico in the hope depleted oil transport would paralyse shipyard output. 33 were sunk in July, then Dönitz lost his first crew. The USN introduced effective convoy systems thereafter ending the "carnage."
Dönitz maintained his demands for the concentration of all his crews in the Atlantic. As the military situation in North Africa and on the Eastern Front began to deteriorate Hitler diverted a number of submarines to the Battle of the Mediterranean upon the suggestions of Admiral Eberhard Weichold. Raeder and Dönitz resisted the deployment to the Mediterranean to no avail. Hitler felt compelled to act against Allied sea forces which were having an enormous impact on Axis supply lines to North Africa. The decision defied logic, for a victory in the Atlantic would end the war in the Mediterranean. The U-boat war in the Mediterranean was a costy failure, despite successes against warships. Approximately 60 crews were lost and only one crew managed to withdraw through the Strait of Gibraltar. Albrecht Brandi was one of Dönitz's highest performers but his record is a matter of controversy. He survived his boat's sinking and was smuggled to Germany through Spain. Dönitz had met his end as a submarine commander in the Mediterranean two decades earlier.
In 1942 Dönitz summed up his philosophy in one simple paragraph; "The enemy's shipping constitutes one single, great entity. It is therefore immaterial where a ship is sunk. Once it hs been destroyed it has to be replaced by a new ship; and that's that." The remark was the green light to unrestricted submarine warfare and began the tonnage war proper. BdU intelligence concluded the Americans could produce 15,300,000 tons of shipping in 1942 and 1943—two million tons under actual production figures. Dönitz always calculated the worst case scenario using the highest figures of enemy production potential. Some 700,000 tons per month needed to be sunk to win the war. The "second happy time" reached a peak in June 1942, with 325,000 tons sunk, up from 311,000 in May, 255,000 in April and the highest since the 327,000 tons sunk in March 1942. With support from the Royal Navy and Royal Canadian Navy, the new convoy systems compelled Dönitz to withdraw his captains to the mid-Atlantic once again. Nevertheless, there was still cause for optimism. B-Dienst had cracked the convoy ciphers and by July 1942 he could call upon 311 boats, 140 operational, to conduct a renewed assault. By October 1942 he had 196 operational from 365. Dönitz's force finally reached the desired number both he and Raeder had hoped for in 1939. Unaware of it, Dönitz and his men were aided by the ULTRA blackout. The addition of a fourth rota to the Enigma left radio detection the only way to gather intelligence on dispositions and intentions of the German naval forces. German code breakers had their own success in the capture of the code book to Cipher Code Number 3 from a merchant ship. It was as treble success for the BdU.
Dönitz was content that he now had the naval power to extend U-boat operations to other areas aside the North Atlantic. The Caribbean, Brazilian waters with the coast of West Africa designated operational theatres. Waters in the southern hemisphere to South Africa could also be attacked with the new Type IX submarine. The strategy was sound and his tactical ideas were effective. The number of boats available allowed him to form Wolfpacks to comb convoy routes from east to west attacking one when found and pursuing it across the ocean. The pack then refuled from a U-boat tanker and worked from west to east. Raeder and the operations staff disputed the value in attacking convoys heading westward with empty cargo holds. The tactics were successful but placed great strain on crews who spent up to eight days in constant action.
November 1942 was a new high in the Atlantic. 134 ships were sunk for 807,754 tons. 119 were destroyed by submarines, 83 (508,707 tons) in the Atlantic. The same month Dönitz suffered strategic defeat. His submarines failed to prevent Operation Torch, even with 196 of them operating in the Atlantic. Dönitz considered it a major self-inflicted defeat. Allied morale radically improved after the victories of Torch, Second Battle of El Alamein and Battle of Stalingrad; all occurred within days of one another. The U-boat war was the only military success the Germans enjoyed at the end of the year.
Commander-in-chief and Grand Admiral
On 30 January 1943, Dönitz replaced Erich Raeder as Commander-in-Chief of the Navy (Oberbefehlshaber der Kriegsmarine) and Großadmiral (grand admiral) of the Naval High Command (Oberkommando der Marine). In a communique to the navy he announced his intentions to retain practical control of the U-boats and his desire to fight to the end for Hitler. Dönitz's inability to delegate control of the U-boat service has been construed as a weakness in the U-boat arm, contributing to the perception that Dönitz was an "impatient warrior", preoccuppied with fighting battles and tactics rather than a strategist or organiser.
Dönitz's promotion earned Hitler his undying loyalty. For Dönitz, Hitler had given him a "true home-coming at last, to a country in which unemployment appeared to have been abolished, the class war no longer tore the nation apart, and the shame of defeat in 1918 was being expunged." When war came, Dönitz became more firmly wedded to his Nazi faith. Hitler recognised his patriotism, professionalism but above all, his loyalty. Dönitz remained so, long after the war was lost. In so doing, he wilfully ignored the genocidal nature of the regime and claimed ignorance of the Holocaust.
In the last quarter of 1942, 69 submarines had been commissioned taking the total number to 393, with 212 operational. Dönitz was not satisfied and immediately began a naval construction programme which in contrast to Raeder's, laid all its emphasis on torpedo boats and submarines. Dönitz's proposed expansion ran into difficulties experienced by all of his predecessors; the lack of steel. The navy had no representation in or to Albert Speer's armament ministry for naval production was the only sphere not under his control. Dönitz understood this worked against the navy because it lacked the elasticity to cope with breakdowns of production at any point, whereas the other services could make good production by compensating one sector at the expense of another. Without any representatives the battle of priorities was left to Speer and Göring. Dönitz had the sense to place U-boat production under Speer on the proviso 40 per month were completed. Dönitz persuaded Hitler not to scrap the surface fleet capital ships, though they played no role in the Atlantic during his time in command. Dönitz reasoned the destruction of the surface fleet would provide the British with a victory and heap pressure on the U-boats, for these warships were tying down British air and naval forces that would otherwise be sent into the Atlantic.
New construction procedures, dispensing with prototypes and the abandonment of modifications reduced construction times from 460,000 man hours to 260–300,000 to meet Speer's quota. In the spring 1944, the Type XXI submarine was scheduled to reach frontline units. In 1943 however, the Combined Bomber Offensive complicated the planned production. Dönitz and Speer were appalled by the destruction of Hamburg, a major construction site. The battles of 1943 and 1944 were fought with the existing VII and Type IX submarines. The type VII remained the backbone of the fleet in 1943.
At the end of 1942, Dönitz was faced with the appearance of escort carriers, and long-range aircraft working with convoy escorts. To protect his boats against the latter, he ordered his boats to restrict their operations to the Mid-Atlantic Gap , a stretch of ocean out of the range of land‐based aircraft referred to by the Germans as "the black hole." Allied air forces had few aircraft equipped with ASV radar for U-Boat detection into April and May 1943, and such units would not exist in Newfoundland until June. Convoys relied on RAF Coastal Command aircraft operating from Northern Ireland and Iceland. The aircraft imposed restraints on U-boat captains, who feared them for their ability to sink a submarine or alert surface warships to their position. In 1942 Coastal Command began forming units combined with ASV and Leigh Light groups to attack U-boats in transit to the Atlantic via the Bay of Biscay, which continued into 1943. The Command was moderately successful after mid–1942.
1943 began with continued tactical success for Dönitz in battle. In January Convoy TM 1 was nearly destroyed. The loss of 100,000 tons of fuel in one convoy represented the most devastating loss percentage if the war—only two of nine tankers reached port. The British 8th Army were forced to ration their fuel for a time, warning Dönitz the gratitude of the Afrika Korps. The Casablanca Conference, held that month, identified the Atlantic as the urgent priority. It was agreed that until the defeat of Dönitz and his men, there could be no amphibious landings in continental Europe. Unknown to Dönitz, Bletchley Park had restored the flow of Enigma information and the Admiralty was able to re-route convoys around wolfpacks. During January and February 1943 information was decrypted within 24 hours proving operationally useful, although this slipped at the end of the second month contributing to German interceptions. Even so, in appalling hunter weather, the Germans sank only 44 ships during the month, even with 100 U-boats at sea, the majority stationed in the mid–Atlantic air gap.
In February 1943 the strength of Allied defences were an ominous sign for Dönitz. The battle of HX 224 was ended upon the intervention of air power from Iceland. Dönitz sent 20 boats to attack SC 118 and both sides suffered heavy losses—11 merchants for three U-boats plus four damaged. It was "what both sides considered one of the hardest fought battles of the Atlantic war." Despite sending 20 crews into action, Dönitz was concerned that most captains did not press home attacks. The majority of the ships sunk were by one crew, commanded by Siegfried von Forstner—he sank seven.
In March, Convoy SC 121 was attacked by 31 U-boats in two patrol lines. It was the most successful battle of the war for Dönitz. The battle of Convoys HX 229/SC 122 was the largest convoy battle, with 40 U-boats involved. Each operation was successful, but all were fought in the mid–Atlantic. Allied losses reached a peak in March 1943. The Admiralty later issued a report on the matter; "The Germans never came so near [to] disrupting communications between the new world and the old as in the first twenty days of March 1943." Dönitz later conceded the March battles were to be the U-boats last victories. New Allied techniques, tactics and technology began to turn the tide. By April 1943 U-boat morale was reaching a crisis point. 98 new boats were sent unto the Atlantic that month, and although the training was thorough the crews were inexperienced and it showed. 15 U-boats were destroyed in March 1943 and another 15 in April. Werner Hartenstein and Johann Mohr were notable casualties over the course of these eight weeks; the former's decision to rescue survivors of a sunken ship led to Dönitz's Laconia Order, which later formed part of the criminal case against Dönitz.
Ominous for BdU was the sudden growth of Allied air power. The Allied command accepted that air cover over the mid–Atlantic was totally inadequate and had drawn attention to the fact that not one VLR (Very Long Range) aircraft was to be found at any Allied air base west of Iceland. The Americans released 255 Liberators for the North Atlantic. At the end of March 1943 20 VLR aircraft were operational rising to 41 by mid-April, all of them flown by British crews. 28 anti-submarine and 11 anti-shipping squadrons were available to RAF Coastal Command, 619 aircraft in all—a striking change since September 1939. The influx of radar equipped aircraft into mid–Atlantic was matched by air patrols over the Bay of Biscay. Dönitz detected a drop in morale among his captains, as did the British. Dönitz encouraged his commanders to show a "hunter's instinct" and "warrior spirit" in the face of the air–surface support group threat.
Along with air power, the BdU was forced to contend with a large increase in available Allied convoy escorts which replenished their tanks from tankers in the convoys allowing escort across the ocean. The escort carrier support groups, protected by destroyers, which, in the words of the official naval historian of the Second World War, proved decisive; "it was the advent of the Support Groups, the Escort Carriers and the Very Long Range Aircraft which turned the tables on the U-boats-and did so with astonishing rapidity."
108 ships were sunk in the first 20 days of March, and just 15 in the last 10. The official naval historian wrote, "The collapse of the enemy's offensive, when it came, was so sudden that it took him completely by surprise. We now know that, in fact, a downward trend in the U-boats' recent accomplishments could have forewarned him, but was concealed from him by the exaggerated claims made by their commanders." In April Dönitz lost five crews to Coastal Command's ASV Bay offensive. Encouraged by the isolated successes of anti-aircraft artillery installed on submarines, he ordered crews to stay on the surface and fight it out with the aircraft. The decision caused casualties—four boats were lost in the first week of May alone, and three more by the end.
For the month of April Allied losses fell to 56 ships of 327,943 tons. In May 1943 the battle reached a climax with the battles of Convoy ONS 5, Convoy SC 129, Convoy SC 130. Throughout the battles only two ships were sunk in convoy in the Atlantic while an air anti-submarine escort was present. Dönitz depended on the surface manoeuvreability of his U-boats to locate targets, assemble wolfpacks and the complicated business of positioning his forces ahead of a convoy for an attack. Allied air power determined where and when U-boats could move freely surfaced. It was the combination of convoy escorts and air power that made the Atlantic unsuitable for pack operations. The US Navy introduced the K-class blimp. They forced a commander to dive to prevent the vehicle marking his position or attacking directly. From 10–24 May 1943, ten convoys passed through the mid–Atlantic. Six of the 370 ships were sunk; three were stragglers. 13 U-boats were sunk; four by warships, seven by aircraft, and two shared.
By the 24 May, when Dönitz conceded defeat and withdrew the surviving crews from the field of battle, they had already lost 33 U-boats. At the end of May it had risen to 41. Dönitz tried to limit the damage to morale by declaring that the withdrawal was only temporary "to avoid unnecessary losses in a period when our weapons are shown to be at a disadvantage" and that "the battle in the north Atlantic—the decisive area-will be resumed." Dönitz did make a further attempt to regain the initiative, but the battle never reached the same pitch of intensity, or hung in the balance, as during the spring of 1943. Consequently, the Allied success is described as decisive in winning the Battle of the Atlantic. On 24 May Dönitz ordered the suspension of Atlantic operations, bringing an end to Black May.
Defeat in the mid-Atlantic left Dönitz in a dilemma. The U-boats had proven unable to elude convoy escorts and attack convoys with success. He was concerned about crew morale suffering from idleness and a loss of experience with the latest Allied developments in anti-submarine warfare. Aside from problems of seaworthiness among machines and crew, there were not enough Submarine pens to store idle boats and they were a target for aircraft in port. Dönitz would not withdraw his submarines from combat operations, for he felt the ships, men and aircraft engaged in suppressing the U-boats could then be turned on Germany directly. The U-boat war was to continue.
From mid–June 1943 the technological and industrial superiority of the Allied navies allowed the Americans, Canadians and British to form Hunter-killer Groups consisting of fast anti-submarine escorts and aircraft carriers. The purpose of naval operations changed from avoiding U-boats to seeking them out and destroying them where ever they operated.
Dönitz could only react, and deployed his U-boats near the Azores, where land–based aircraft still had difficulty reaching them. In this region, he hoped to threaten the Gibraltar—Britain convoy route. Dönitz intended to concentrate his power in a rough arc from West Africa to South America and the Caribbean. He hoped to maintain a presence in the western and central Atlantic, and await new weapons and anti-detection devices.
Dönitz's crews faced danger from the outset. The transit routes through the Bay of Biscay were heavily patrolled by aircraft. From May—December 1943, 25 U-boats were sunk by Coastal Command, more were sunk by the USAAF and Royal Navy—five and four respectively; with one shared by the navy and Coastal Command. To counter radar aircraft, Dönitz ordered his submarines to group together and merge their powerful anti aircraft armament together while surfaced and recharging their batteries, after initially ordering the groups to remain surfaced throughout the journey and fight off aerial attackers with gunfire. The decision was to cost BdU heavy casualties. A group of U-boats were more likely to attract a radar contact, and Allied pilots soon learned to swarm their targets.
US hunter–killer groups extended their patrols to the central Atlantic in the summer. They sank 15 U-boats from June through to August 1943. A number of supply submarines were destroyed crippling the Germans ability to conduct long range operations. In September 1943, Dönitz ordered his submarines back to the North Atlantic. That month, 21 boats fought a battle with two formations; Convoys ONS 18/ON 202. Dönitz's U-boats were equipped with the G7es torpedo, an acoustic torpedo, which the grand admiral hoped would wrest the technological initiative back.
President of Germany
In the final days of the war, after Hitler had taken refuge in the Führerbunker beneath the Reich Chancellery garden in Berlin, Reichsmarschall Hermann Göring was considered the obvious successor to Hitler, followed by Reichsführer-SS Heinrich Himmler. Göring, however, infuriated Hitler by radioing him in Berlin asking for permission to assume leadership of the Reich. Himmler also tried to seize power by entering into negotiations with Count Bernadotte. On 28 April 1945, the BBC reported Himmler had offered surrender to the western Allies and that the offer had been declined.
From mid-April 1945, Dönitz and elements of what remained of the Reich government moved into the buildings of the Stadtheide Barracks in Plön. In his last will and testament, dated 29 April 1945, Hitler named Dönitz his successor as Staatsoberhaupt (Head of State), with the titles of Reichspräsident (President) and Supreme Commander of the Armed Forces. The same document named Propaganda Minister Joseph Goebbels as Head of Government with the title of Reichskanzler (Chancellor). Furthermore, Hitler declared both Göring and Himmler traitors and expelled them from the party.
On 1 May, the day after Hitler's own suicide, Goebbels committed suicide. Dönitz thus became the sole representative of the crumbling German Reich. He appointed Finance Minister Count Ludwig Schwerin von Krosigk as "Leading Minister" (Krosigk had declined to accept the title of Chancellor), and they attempted to form a government.
On 1 May, Dönitz announced that Hitler had fallen and had appointed him as his successor. On 2 May, the new government of the Reich fled to Flensburg-Mürwik before the approaching British troops. That night, Dönitz made a nationwide radio address in which he announced Hitler's death and said the war would continue in the East "to save Germany from destruction by the advancing Bolshevik enemy". However, Dönitz knew that Germany's position was untenable and the Wehrmacht was no longer capable of offering meaningful resistance. During his brief period in office, he devoted most of his effort to ensuring the loyalty of the German armed forces and trying to ensure German troops would surrender to the British or Americans and not the Soviets. He feared vengeful Soviet reprisals, and hoped to strike a deal with the Western Allies. In the end, Dönitz's tactics were moderately successful, enabling about 1.8 million German soldiers to escape Soviet capture. His authority was effectively limited to a narrow band of territory running from the Austrian border through Berlin to the Danish border, and even that had been cut in two by the American advance to join with Soviet forces at Torgau on the Elbe.
On 4 May, Admiral Hans-Georg von Friedeburg, representing Dönitz, surrendered all German forces in the Netherlands, Denmark, and northwestern Germany under Dönitz's command to Field Marshal Sir Bernard Law Montgomery at Lüneburg Heath just southeast of Hamburg, signalling the end of World War II in northwestern Europe.
A day later, Dönitz sent Friedeburg to US General Dwight D. Eisenhower's headquarters in Rheims, France, to negotiate a surrender to the Allies. The Chief of Staff of OKW, Generaloberst (Colonel-General) Alfred Jodl, arrived a day later. Dönitz had instructed them to draw out the negotiations for as long as possible so that German troops and refugees could surrender to the Western powers, but when Eisenhower let it be known he would not tolerate their stalling, Dönitz authorised Jodl to sign the instrument of unconditional surrender at 1:30 on the morning of 7 May. Just over an hour later, Jodl signed the documents. The surrender documents included the phrase, "All forces under German control to cease active operations at 23:01 hours Central European Time on 8 May 1945." At Stalin's insistence, on 8 May, shortly before midnight, (Generalfeldmarschall) Wilhelm Keitel repeated the signing in Berlin at Marshal Georgiy Zhukov's headquarters, with General Carl Spaatz of the USAAF present as Eisenhower's representative. At the time specified, World War II in Europe ended.
On 23 May, the Dönitz government was dissolved when Dönitz was arrested by an RAF Regiment task force. The Großadmiral's Kriegsmarine flag, which was removed from his headquarters, can be seen at the RAF Regiment Heritage Centre at RAF Honington. Generaloberst Jodl, Reichsminister Speer and other members were also handed over to troops of the King's Shropshire Light Infantry at Flensburg. His ceremonial baton, awarded to him by Hitler, can be seen in the regimental museum of the KSLI in Shrewsbury Castle.
Nazism and antisemitism
Dönitz was a dedicated Nazi and a passionate supporter of Hitler, something he tried to obscure after the war. Raeder described him as "a picture-book Nazi and confirmed anti-Semite". Several naval officers described him as "closely tied to Hitler and Nazi ideology." On one occasion, he spoke of Hitler's humanity. Another event, in which he spoke to Hitler Youth in what was defined as an "inappropriate way," earned him the nickname of "Hitler Youth Dönitz." He refused to help Albert Speer stop the scorched earth policy dictated by Hitler and is also noted to have declared, "In comparison to Hitler we are all pipsqueaks. Anyone who believes he can do better than the Führer is stupid."
Dönitz contributed to the spread of Nazism within the Kriegsmarine. He insisted that officers share his political views and, as head of the Kriegsmarine, formally joined the Nazi Party on 1 February 1944, as member 9,664,999. He was awarded the Golden Party Badge for his loyalty to the party later that year. Dönitz's influence over naval officers contributed to none joining the attempts to kill Hitler.
From an ideological standpoint, Dönitz was anti-Marxist and antisemitic who believed that Germany needed to fight the "poison of Jewry". Several anti-Semitic statements by Dönitz are known. When Sweden closed its international waters to Germany, he blamed this action on their fear and dependence on "international Jewish capital." In August 1944, he declared, "I would rather eat dirt than see my grandchildren grow up in the filthy, poisonous atmosphere of Jewry."
His fellow officers noted he was under Hitler's influence, and closely wedded to Nazi ideology. On German Heroes' Day (12 March) of 1944, Dönitz declared that, without Adolf Hitler, Germany would be beset by "the poison of Jewry," and the country destroyed for lack of the "uncompromising ideology" of National Socialism. "What would have become of our country today, if the Fuehrer had not united us under National Socialism? Divided along party lines, beset with the spreading poison of Jewry and vulnerable to it, because we lacked the defense of our present uncompromising ideology, we would have long since succumbed under the burden of this war and delivered ourselves to the enemy who would have mercilessly destroyed us."
At the Nuremberg trials, Dönitz claimed the statement about the "poison of Jewry" was regarding "the endurance, the power to endure, of the people, as it was composed, could be better preserved than if there were Jewish elements in the nation." Later, during the Nuremberg trials, Dönitz claimed to know nothing about the extermination of Jews and declared that nobody among "my men thought about violence against Jews." Dönitz told Leon Goldensohn, an American psychiatrist at Nuremberg, "I never had any idea of the goings-on as far as Jews were concerned. Hitler said each man should take care of his business and mine was U-boats and the Navy." After the war Dönitz tried to hide his knowledge of the Holocaust. He was present at the October 1943 Posen Conference where Himmler described the mass murder of Jews with the intent of making the audience complicit in this crime. It cannot be proven beyond doubt that he was present during Himmler's segment of the conference, which openly discussed the murder of European Jewry.
Even during his imprisonment, after Nuremburg, with the crimes of the Nazi state well-known, Dönitz was unable to rid himself of his antisemitism. In April 1953, he told Speer that if it was the choice of the Americans and not the Jews, he would have been released.
Nuremberg war crimes trials
Following the war, Dönitz was held as a prisoner of war by the Allies. He was indicted as a major war criminal at the Nuremberg Trials on three counts. One: conspiracy to commit crimes against peace, war crimes, and crimes against humanity. Two: planning, initiating, and waging wars of aggression. Three: crimes against the laws of war. Dönitz was found not guilty on count one of the indictment, but guilty on counts two and three.
During the trial, army psychologist Gustave Gilbert was allowed to examine Nazi leaders on trial for war crimes. Among other tests, a German version of the Wechsler–Bellevue IQ test was administered. Dönitz and Hermann Göring scored 138, which made them equally the third-highest among the Nazi leaders tested.
At the trial, Dönitz was charged with waging unrestricted submarine warfare against neutral shipping, permitting Hitler's Commando Order of 18 October 1942 to remain in full force when he became commander-in-chief of the Navy, and to that extent responsibility for that crime. His defence was that the order excluded men captured in naval warfare, and that the order had not been acted upon by any men under his command. Added to that was his knowledge of 12,000 involuntary foreign workers working in the shipyards, and doing nothing to stop it.
On 25 February 1945, Hitler asked Dönitz whether the Geneva Convention should be denounced. Hitler's motives were twofold. The first was that reprisals could be taken against Western Allied prisoners of war; second, it would deter German forces from surrendering to the Western Allies, as was happening on the Eastern Front where the convention was in abeyance. Instead of arguing the conventions should never be denounced, Dönitz suggested it was not expedient to do so, so the court found against him on this issue; but as the convention was not denounced by Germany, and British prisoners in camps under Dönitz's jurisdiction were treated strictly according to the Convention, the Court considered these mitigating circumstances.
Among the war-crimes charges, Dönitz was accused of waging unrestricted submarine warfare for issuing War Order No. 154 in 1939, and another similar order after the Laconia incident in 1942, not to rescue survivors from ships attacked by submarine. By issuing these two orders, he was found guilty of causing Germany to be in breach of the Second London Naval Treaty of 1936. However, as evidence of similar conduct by the Allies was presented at his trial, his sentence was not assessed on the grounds of this breach of international law.
On the specific war crimes charge of ordering unrestricted submarine warfare, Dönitz was found "[not] guilty for his conduct of submarine warfare against British armed merchant ships", because they were often armed and equipped with radios which they used to notify the admiralty of attack. As stated by the judges: "Dönitz is charged with waging unrestricted submarine warfare contrary to the Naval Protocol of 1936 to which Germany acceded, and which reaffirmed the rules of submarine warfare laid down in the London Naval Agreement of 1930 ... The order of Dönitz to sink neutral ships without warning when found within these zones was, therefore, in the opinion of the Tribunal, violation of the Protocol ... The orders, then, prove Dönitz is guilty of a violation of the Protocol ... The sentence of Dönitz is not assessed on the ground of his breaches of the international law of submarine warfare."
His sentence on unrestricted submarine warfare was not assessed, because of similar actions by the Allies. In particular, the British Admiralty, on 8 May 1940, had ordered all vessels in the Skagerrak sunk on sight, and Admiral Chester Nimitz, wartime commander-in-chief of the US Pacific Fleet, stated the US Navy had waged unrestricted submarine warfare in the Pacific from the day the US officially entered the war. Thus, Dönitz was found guilty of waging unrestricted submarine warfare against unarmed neutral shipping by ordering all ships in designated areas in international waters to be sunk without warning.
Dönitz was imprisoned for 10 years in Spandau Prison in what was then West Berlin. During his period in prison he was unrepentant, and maintained that he had done nothing wrong. He also rejected Speer's attempts to persuade him to end his devotion to Hitler and accept responsibility for the wrongs the German Government had committed. Over 100 senior Allied officers also sent letters to Dönitz conveying their disappointment over the fairness and verdict of his trial.
Dönitz was released on 1 October 1956 and retired to the small village of Aumühle in Schleswig-Holstein in northern West Germany. There, he worked on two books. His memoirs, Zehn Jahre, Zwanzig Tage (Memoirs: Ten Years and Twenty Days), were released in Germany in 1958 and became available in an English translation the following year. This book recounted Dönitz's experiences as U-boat commander (10 years) and President of Germany (20 days). In it, Dönitz explains the Nazi regime as a product of its time, but argues he was not a politician and thus not morally responsible for many of the regime's crimes. He likewise criticizes dictatorship as a fundamentally flawed form of government and blames it for many of the Nazi era's failings. Historian Alan P. Rems has written that his memoirs are unconvincing and "unimpeded by a meaningful Nuremberg verdict, Dönitz fashioned a legend that could be embraced by the most unregenerate Nazis as well as credulous Allied officers who accepted his sanitized version of history and showered Dönitz with letters of support as a wronged brother-in-arms".
Dönitz's second book, Mein wechselvolles Leben (My Ever-Changing Life) is less known, perhaps because it deals with the events of his life before 1934. This book was first published in 1968, and a new edition was released in 1998 with the revised title Mein soldatisches Leben (My Martial Life). In 1973, he appeared in the Thames Television production The World at War, in one of his few television appearances.
Dönitz was unrepentant regarding his role in World War II, saying that he had acted at all times out of duty to his nation. He lived out the rest of his life in relative obscurity in Aumühle, occasionally corresponding with collectors of German naval history, and died there of a heart attack on 24 December 1980. As the last German officer with the rank of Großadmiral (grand admiral), he was honoured by many former servicemen and foreign naval officers who came to pay their respects at his funeral on 6 January 1981. He was buried in Waldfriedhof Cemetery in Aumühle without military honours, and service members were not allowed to wear uniforms to the funeral. Also in attendance were over 100 holders of the Knight's Cross of the Iron Cross.
