World War II

Combat chronicle

The 103d Infantry Division was ordered into active military service on 15 November 1942 at Camp Claiborne, Louisiana and after nearly two years of training, departed the United States for Europe on 5 October 1944. The division arrived at Marseilles, France, 20 October 1944. It relieved the 3d Division at Chevry on 8 November, arrived at Docelles (Vosges) on 9 November, and attacked west of St. Dié, 16 November, in its drive through the Vosges. Meeting heavy resistance all the way, it crossed the Meurthe River, took St. Dié, 23 November and captured Diefenbach on 29 November and Selestat on 4 December.

The division crossed the Zintzel river at Griesbach, 10 December 1944. Pushing through Climbach, the 103d crossed the Lauter River into Germany, 15 December, and assaulted the outer defenses of the Siegfried Line. On 22 December, the division moved west to the Sarreguemines area where an active defense was maintained. The enemy offensive did not develop in its sector and the 103d moved to Reichshofen, 14 January 1945, to take up positions along the Sauer River. On 15 January, General Anthony "Nuts" McAuliffe was redeployed from the Battle of the Bulge and given command, which he retained until July 1945. Defensive patrols were active and a limited attack on Soufflenheim on 19 January was repulsed by the enemy. On 20 January, the division withdrew to the Moder and repulsed German advances near Muehlhausen, 23–25 January. The 103d's offensive began, 15 March 1945. Crossing the Moder and Zintzel rivers and taking Muehlhausen against sharp opposition, the division moved over the Lauter river and penetrated the defenses of the Siegfried Line.

As German resistance disintegrated, the 103d reached the Upper Rhine Valley, 23 March, and engaged in mopping up operations in the plain west of the River Rhine. In April 1945, it received occupational duties until 20 April when it resumed the offensive, pursuing a fleeing enemy through Stuttgart and taking Münsingen on 24 April. On 27 April, elements of the division entered Landsberg, where Kaufering concentration camp, a subcamp of Dachau, was liberated.[4][5] The men of the division crossed the Danube River near Ulm on 26 April. On 3 May 1945, members of its 409th Infantry Regiment captured Innsbruck, Austria with little to no fighting. The 411th Infantry Regiment continued on to take the Brenner Pass and earn the honor of linking up with the 88th Infantry Division of the Fifth Army which had been fighting its way north up the Italian peninsula. Troops met at Vipiteno, Italy, near the Austrian border on 4 May 1945, joining the Italian and Western European fronts.[2]

After Victory in Europe Day the division received occupational duties until it left for home and inactivation.

It returned to the continental U.S on 10 September 1945, and was inactivated on 22 September 1945 at Camp Kilmer, New Jersey.
