The 11th Panzer Division was part of Case Blue from June 1942 onward, participating in the capture of Voronezh and the drive towards Stalingrad. It avoided being entrapped with the 6th Army in the city but suffered substantial losses during the winter of 1942-43. It was engaged in the failed relief attempt on Stalingrad and then participated in the defence of Rostov, which allowed the German troops retreating from the Caucasus to escape.
