The Battles of Rzhev were a series of Red Army offensives against the Wehrmacht between 8 January 1942 and 31 March 1943, on the Eastern Front of World War II. The battles took place in the northeast of Smolensk Oblast and the south of Tver Oblast, in and around the salient surrounding Rzhev. Due to the high losses suffered by the Red Army, the campaign became known by veterans and historians as the "Rzhev Meat Grinder".
