In the Battle of Kursk, the Germans are estimated to have lost some 2000 tanks and thousands of pieces of artillery. They also lost some 700 planes. The Soviet lost some 250,000 men, killed or missing in action. Some 6000 Soviet tanks, 3000 guns and one thousand planes are lost during the battle.
The Battle of Kursk was an Eastern Front engagement between German and Soviet forces near Kursk (450 kilometres or 280 miles south-west of Moscow) in the Soviet Union, during July and August 1943. The battle began with the launch of the German offensive, Operation Citadel (German: Unternehmen Zitadelle), on 5 July, which had the objective of pinching off the Kursk salient with attacks on the base of the salient from north and south simultaneously. After the German offensive stalled on the northern side of the salient, on 12 July the Soviets commenced their Kursk Strategic Offensive Operation with the launch of Operation Kutuzov (Russian: Кутузов) against the rear of the German forces in the northern side.
On the southern side, the Soviets also launched powerful counterattacks the same day, one of which led to a large armoured clash, the Battle of Prokhorovka. On 3 August, the Soviets began the second phase of the Kursk Strategic Offensive Operation with the launch of Operation Polkovodets Rumyantsev (Russian: Полководец Румянцев) against the German forces in the southern side of the Kursk salient.
The battle was the final strategic offensive that the Germans were able to launch on the Eastern Front. Because the Allied invasion of Sicily had begun, Adolf Hitler was forced to have troops training in France diverted to meet the Allied threat in the Mediterranean, rather than use them as a strategic reserve for the Eastern Front. Hitler canceled the offensive at Kursk after only a week, in part to divert forces to Italy.
