Cause

Germany sought to eliminate the Soviet-held Kursk salient, expecting a victory would reassert German strength, impress wavering allies, and yield large numbers of Soviet prisoners for slave labour. The Soviets, forewarned by the Lucy spy ring, spent months constructing deep defensive belts and massing reserves. German delays in awaiting new weapons gave the Red Army additional preparation time.

Event

On 5 July 1943, Germany launched Operation Citadel, attacking the Kursk salient from north and south simultaneously. After the northern German advance stalled, the Soviets launched Operation Kutuzov on 12 July. That same day, powerful Soviet counterattacks in the south produced the Battle of Prokhorovka. On 3 August, the Soviets opened the Belgorod–Kharkov offensive, completing the encirclement of the salient's southern German forces.

Consequence

Hitler cancelled Operation Citadel after about a week, partly to divert troops to counter the Allied invasion of Sicily. Germany's heavy losses of men and armour permanently shifted strategic initiative to the Soviet Union. The Red Army's subsequent summer offensives, the first successful ones of the war, drove German forces steadily westward for the remainder of the conflict.
