The largest tank battle in history took place at Kursk. The battle took place between July 3 qnd 12 1943. The Germans planned a counter-offensive on Soviet positions. Their target was the Kursk salient. Their goal was to cut off the salient and capture the 60 Soviet battalions inside. The Soviets, however, were prepared, and 900 German tanks met 900 Soviet ones. The battle continued for nearly a week, and ended in a draw when Hitler ended the German offensive..
The Germans would never be able to amass the number of tanks they had at Kursk, while the Soviets were out-producing them every month.
