The Battle of Kursk in 1943 was the largest tank battle in history. It was between the German Wehrmacht and the Soviet Red Army. German forces attempted to encircle Soviet forces in the Kursk Salient on the eastern front, but strong Soviet resistance defeated the German assault. Kursk was the last German offensive of any strategic significance in the east; henceforth, they would conduct a fighting retreat. Germany already suffered from a grave shortage of war resources, when Hitler ordered the offensive and lost a huge number of tanks such as the new Tigertank and the Panther.
