Battles of Rzhev
The offensive was a joint operation of the Soviet Western Front and Kalinin Front co-ordinated by Georgy Zhukov. The offensive was one in a series of particularly-bloody engagements that are collectively known in Soviet and Russian histories as the Battles of Rzhev, which occurred near Rzhev, Sychevka and Vyazma between January 1942 and March 1943. The battles became known as the "Rzhev meat grinder" ("Ржевская мясорубка") for their huge losses, particularly on the Soviet side. For many years, they were relegated to a footnote in Soviet military history.
