Cause

Following months of costly attritional fighting around the Rzhev salient near Moscow, Soviet High Command sought to eliminate the German-held bulge that threatened the capital. The salient had been a persistent strategic liability, and Soviet forces under Zhukov planned a large-scale offensive to encircle and destroy German forces holding the position.

Event

Operation Mars was launched on 25 November 1942, with the Soviet Western Front and Kalinin Front conducting a coordinated assault on the Rzhev salient. The operation aimed to break through German defenses around Rzhev, Sychevka, and Vyazma. Fighting lasted until 20 December 1942 and was characterized by extremely high Soviet casualties as repeated assaults failed to achieve a decisive breakthrough against well-prepared German defensive lines.

Consequence

The offensive failed to eliminate the Rzhev salient, resulting in enormous Soviet losses that earned the battles the epithet 'Rzhev meat grinder.' For decades the operation was minimized in Soviet military historiography. The German salient was eventually evacuated in early 1943 during Operation Buffalo, not as a result of Soviet offensive success.
