On November 23,1942, and following the November 19, 1942 beginning of Operation Uranus, the spearheads from the Soviet Southwest and Stalingrad fronts, met at Kalach to Stalingrad’s west. They had cut off the entire German 6th Army and part of the 4th Panzer Army in a massive pocket. Following a belated and thwarted German relief effort the final role for the formerly proud and merciless 6th Army was to tie down the Soviet armies around Stalingrad as German Army Group A completed its withdrawal from the Caucusus.
