However, it is widely documented that the fighting continued undiminished into September and did not finally cease until the beginning of October 1942.The Red Army suffered massive casualties for little gain during the fighting, giving the battle a notoriety reflected in its sobriquet: "The Rzhev Meat Grinder".
