Lvov–Sandomierz Offensive
Hauffe was General of Infantry during the Lvov–Sandomierz Offensive. The Lvov-Sandomierz Offensive was a major Red Army operation to force the German troops from Ukraine and Eastern Poland which was launched in mid July 1944. During this military engagement, General Hauffe failed to prepare for the withdrawal of his troops when they were threatened by encirclement. He also failed to show up at headquarters during the final phase of the offensive from 20 July 1944 to 22 July 1944 thus forcing Lieutenant General Wolfgang Lange to assume command of the XIII Army Corps. His inaction lead to the encirclement of his troops in the Brody pocket where they were destroyed. He was captured by Soviet troops on 22 July 1944 and died later the same day when he stepped on a land mine.
