August 23rd, 1943 marked the end of the Battle of Kursk — the largest tank battle in history, with around 3000 tanks from the German side and over 5000 tanks from the Soviet side. It was the first time a German offensive on the Eastern Front failed with no significant gains. The decisive victory of the Red Army led to it gaining a strategic initiative and defined the way the rest of the war was fought.
