In late November 1942, Soviet forces surrounded General Friedrich Paulus' Sixth Army in a pocket at the Russian city of Stalingrad. In response, the Germans planned a relief operation, Operation Winter Thunderstorm, intended to break through the Soviet forces and open the pocket, releasing the encircled units. The 6th Panzer Division was the spearhead of the German relief force. The attack started on 12 December 1942 and was aborted on 23 December after heavy Soviet counterattacks. This failure sealed the fate of the German Sixth Army in Stalingrad. This account of the operation was first published in German in 1956, written by the well-respected military historian and retired German officer, Horst Scheibert, who was a tank commander in 6th Panzer Division during the attempt. Utilising many excerpts from war diaries, and telegrams sent during operations, it is a unique account of the entire operation from the situation in mid-November through the two German offensives, the Soviet counteroffensive and ongoing fighting until early January. This book includes 16 maps from the original edition and is the first English translation of this important German account.
