World War II: The Battle of Kursk, the largest full-scale battle in history and the world's largest tank battle, begins in the village of Prokhorovka.

The Battle of Kursk, also called the Battle of the Kursk Salient, was a major World War II Eastern Front battle between the forces of Nazi Germany and the Soviet Union near Kursk in southwestern Russia during the summer of 1943, resulting in a Soviet victory. The Battle of Kursk is the single largest battle in the history of warfare. It ranks only behind the Battle of Stalingrad several months earlier as the most often-cited turning point in the European theatre of the war. It was one of the costliest battles of the Second World War, the single deadliest armoured battle in history, and the largest tank battle in history. The opening day of the battle, 5 July, was the single costliest day in the history of aerial warfare in terms of aircraft shot down. The battle was further marked by fierce house-to-house fighting and hand-to-hand combat.
