After taking part in the Battle of the Bzura the corps was transferred to Warsaw.

It later moved to western Europe and was eventually stationed in Normandy.

In 1942 the corps was trapped in the Demyansk Pocket near Leningrad, surrounded by Soviet troops and cut off for several months from the rest of the army.

After the breakthrough of the Soviet 51st Army under General Kreiser on 10 October near Polangen on the Baltic Sea, X Corps, with the 11th, 30th, and 61st Infantry Divisions, took command of the southern front of the Courland Pocket.

From October 27 to November 2, 1944, they withstood the main attack of the Soviet 5th Tank Army and sustained losses of more than 4,000 men.
