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. 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.
