XII Army Corps (Wehrmacht)

XII Army Corps (German: XII. Armeekorps) was a corps in the German Army during World War II. It was formed in the Wehrkreis XII recruitment and training district in Wiesbaden in October 1936 and was mobilized before the outbreak of war at the end of August 1939.

At the start of World War II the corps were part of the 1st Army and based in the Saar region. In June 1939 they broke through the Maginot line to the Moselle near Nancy. In 1940 it fought with the 4th Army in Poland.

In Operation Barbarossa in June 1941 the corps were attached to Panzer Group 2 for the attack on the stronghold of Brest-Litovsk. After advancing further into Russia they were held up by Soviet counter-attacks.

Following Operation Bagration, the huge Soviet counter-attack in 1944, XII Corps were forced to retreat in bad condition and in July 1944 were finally destroyed in a pocket east of Minsk. General Müller was taken prisoner.

The corps was reformed in April 1945 to defend the middle Rhine and Thuringia under General Herbert Osterkamp.
