U-28 was commissioned into the Imperial German Navy on 26 June 1914, with Freiherr Georg-Günther von Forstner (1882-1940) in command. Commander von Forstner was relieved on 15 June 1916 by Otto Rohrbeck, who was in turn relieved on 5 August by Freiherr von Loe-Degenhart. On 15 January 1917, Georg Schmidt took command.
On 30 July 1915, U-28 sunk the British steamer Iberian. According to Commander von Forstner's account of the incident, the wreckage remained under the water for about 25 seconds until an explosion sent some of the debris flying up. It is said that along with the debris, a creature described as a "gigantic aquatic animal" resembling a crocodile was seen, which quickly disappeared from sight.
There is still some debate over where this sea monster actually existed, however. Despite popular wisdom, it was not recorded in the submarine's log, and the first time it was ever reported on 19 years later. The Captain had never spoken of it prior. All the alleged witnesses, except for the captain and one other, were killed in action during the war. The other "witness" never spoke about it, even after the story became big.
U-28's final patrol began on 19 August 1917, when it departed from Emden for the Arctic Ocean. On 2 September, at 11:55 am, it encountered the armed English steamer Olive Branch, 85 nautical miles (157 km; 98 mi) north-by-northeast of North Cape, Norway. U-28 scored a torpedo hit, and closed in to finish the steamer with gunfire. The shells detonated Olive Branch's cargo of munitions, which it had been carrying from England to Arkhangelsk, Russia, and the subsequent explosion so badly damaged the U-boat that it sank along with the steamer. All 39 of its crew were lost; some were seen swimming, but were not picked up by Olive Branch's lifeboats.
