Awarded in part for his achievements during the defensive battles along the Bug and the Narew rivers in the fall of 1944, but mainly for his performance during the Soviet Winter offensive of early 1945.
At the beginning of this offensive he mastered many critical situations, and in particular a strong enemy flank attack that came at a time when his division was already heavily engaged. With a handful of Sturmgeschütze he was able to push back the Soviet attack while leading from the front.
It was through Sixt's excellent leadership that the division was able to retreat from the Narew to the Vistula (16-28.01.1945) largely in good order. It had the distinction of being the only formation of the 2. Armee originally positioned along the Narew to reach the west side of the Vistula with all of its artillery and supply troops.
