The Battle of Prokhorovka was fought on 12 July 1943 near Prokhorovka, 87 kilometres (54 mi) southeast of Kursk, in the Soviet Union, during the Second World War. Taking place on the Eastern Front, the engagement was part of the wider Battle of Kursk and occurred when the 5th Guards Tank Army of the Soviet Red Army attacked the II SS-Panzer Corps of the German Waffen-SS in one of the largest tank battles in history. In April 1943, the German leadership began preparing for Operation Citadel, with the objective of enveloping and destroying the Soviet forces in the Kursk salient by attacking and breaking through the base of the salient from north and south simultaneously. The German offensive was delayed several times because of the vacillation of the leadership (Hitler repeatedly delayed launching the attack so that more Tiger tanks could be delivered to the front, hoping that a technical advantage would help him win the offensive) and the addition of more forces and new equipment. The Soviet high command, Stavka, had learned of the German intentions and so used the delay to prepare a series of defensive belts along the routes of the planned German offensive.
