Hitler masses 3,000 tanks at Kursk, and the Red Army has 5,000 waiting
What happened
On 5 July 1943 the Wehrmacht launched Operation Zitadelle, a pincer attack from north and south against a bulge in the front line around Kursk, in what became, in one historian's words, the greatest tank battle of all time. More than 780,000 German troops with nearly 3,000 tanks attacked over 1.9 million Soviet defenders holding more than 5,000 tanks, and as both sides fed in reserves Soviet strength swelled past 2.5 million troops and 7,300 tanks. The German attack never broke through. On 12 July, two days after the Allies landed in Sicily, Hitler told his generals he wanted troops pulled from Kursk and sent to Italy instead, even as the Soviets opened their own counteroffensive further north. The campaign ended on 23 August 1943 with the Red Army seizing the city of Kharkov.
Why it matters
Kursk ended Germany's ability to choose where and when the war in the East would be fought. For the first time, a German offensive had failed to achieve any breakthrough at all, and the strategic initiative passed to the Red Army for the remainder of the war; within six weeks of the battle's opening, Soviet counteroffensives had already retaken Kharkov. Hitler's decision to strip the offensive of troops mid-battle, pulled between the Eastern Front and the new Allied landing in Sicily, made Kursk the moment the two-front squeeze on German strategy stopped being a future risk and became present reality.
How we know
The troop and tank figures used here follow military historian David Glantz's reconstruction from Soviet and German records, as presented by Keith Huxen, PhD, of the National WWII Museum, whose account also documents Hitler's 12 July statement about shifting forces to Italy and the fall of Kharkov on 23 August.
