The 12th Panzer Division was an armoured division in the German Army, established in 1940. In October 1940 the 2nd Motorised Infantry Division was reorganized as the 12th Panzer Division, and in June 1941 it joined Operation Barbarossa, fighting in the battles of Minsk and Smolensk. It fought the rest of the war on the Eastern Front and surrendered to the Red Army in the Courland Pocket in May 1945. History The division was formed from the 2nd Infantry Division, itself formed in 1921. The division was motorised in 1936–37 and participated in the invasions of Poland and France. It was reorganised as a Panzer Division in October 1940. The 12th Panzer Division participated in Operation Barbarossa, taking part in the drive towards Leningrad. Suffering heavy casualties during the Soviet counter offensive in the winter of 1941–42, the division was withdrawn to Estonia for a refit. It remained with Army Group North for the most part of the war except for a brief spell south while participating in the battle of Kursk in July 1943 and the following defensive operations and retreat after the German failure. The division returned to the northern sector in January 1944 but came too late to play any role in the unsuccessful German efforts to prevent the Siege of Leningrad from being broken by the Red Army. It was eventually entrapped in the Courland Pocket after the successful Soviet offensive in July 1944, Operation Bagration. It remained in Courland where it surrendered to Soviet forces in May 1945.
