IX Army Corps (IX. Armeekorps) was a corps in theGerman Army duringWorld War II. It was formed on 1 October 1934 under the command of GeneralFriedrich Dollman inKassel with the camouflage name of Kassel and redesignated IX Corps after the creation of the Wehrkreis IX recruitment and training area.
After the general mobilisation in August 1939 IX Corps were stationed nearWorms as1st Army reserves. In May 1940 they took part inFall Gelb, the Manstein plan to invade the Low Countries and France via theArdennes, pushing on toDunkirk.
Transferred to theEastern Front in 1941 to take part inOperation Barbarossa, the invasion of the Soviet Union, the corps, at that time consisting of137th,263rd and the292nd Infantry Division, were transferred to the4th Army under the overall command of Field MarshalGünther von Kluge. They reached the Dnieper river where they encountered strong Soviet resistance and by the end of 1942 had to fall back. In the spring of 1943 further retreat was necessary.
On 22 June 1944, duringOperation Bagration, the left corps section in the Sirotino area was attacked by seven Soviet divisions of the Soviet 4th Infantry under General Malychev. Further retreats followed up to the end of the year.
By 1945 the corps had fallen back to theDeyma River nearKaliningrad, where they established a defensive position. The German Army surrendered on 8 May 1945.
