The 6th Army was a field army unit of the German Wehrmacht during World War II (1939–1945). It was widely remembered for being the most highly decorated German army unit until its defeat by the Red Army at the Battle of Stalingrad in the winter of 1942–1943. It also acquired a reputation for the war crimes (such as the massacre of more than 30,000 Jews at Babi Yar in September 1941) that it committed under the command of Field Marshal Walther von Reichenau during Operation Barbarossa. Western campaigns Originally numbered as the 10th Army, this Army formed on 10 October 1939 with General Walther von Reichenau in command. Its primary mission was to guard the western defenses of Germany against British and French attacks during the Polish campaign. During the invasion of the Low Countries the 6th Army saw active service linking up with paratroopers and destroying fortifications at Eben Emael, Liège, and Namur during the Battle of Belgium.

Paulus led the 6th Army to a major victory at the Second Battle of Kharkov during the spring of 1942. Battle of Stalingrad On 28 June 1942, Army Group South began Fall Blau, the German Army's summer offensive into southern Russia. The goals of the operation were to secure both the oil fields at Baku, Azerbaijan, and the city of Stalingrad on the river Volga to protect the forces advancing into the Caucasus. After two months, the 6th Army reached the outskirts of Stalingrad on 23 August. On the same day, over 1,000 aircraft of the Luftflotte 4 bombed the city, killing many civilians. Stalingrad was defended by the 62nd Army (Soviet Union) under the command of General Vasily Chuikov. Despite German air superiority over Stalingrad, and with more artillery pieces than the Red Army, progress was reduced to no more than several meters a day. Eventually, by mid November, the
