The 18th Panzer Division first saw action during the German invasion of the Soviet Union,
Operation Barbarossa, on 22 June 1941. The 18th Panzer Division fought as part of
XLVII Panzer Corps, and over the next six months was involved in seizing
Smolensk,
Bryansk and the assault on
Tula. The division suffered heavy losses in the first month of the war, losing half its tanks and a third of its manpower in June and July. With the start of the Soviet counter offensive in December 1941 the 18th Panzer Division was driven back to
Oryol with heavy losses. In the summer of 1942, the 18th Panzer Division took part in the initial drive on
Stalingrad, but was soon transferred to the central section of the front. The 18th Panzer Division took part in
security warfare in the spring of 1943. In the summer of 1943, the division fought in the
Battle of Kursk, and suffered heavy losses. After Kursk the 18th Panzer-Division suffered from poor morale and frequent desertions and was disbanded, with the division's personnel being used to build the
18th Artillery Division. ==War crimes==
