9th Army

Strauss's 9th Army anchored the northern shoulder of the German offensive, clearing the northern face of the Vyazma pocket and then advancing on Kalinin and the upper Volga through October 1941. In November it pushed toward Klin and the Moscow reservoir system alongside the 3rd Panzer Group. The Soviet counteroffensive of December struck its positions head on: under Hitler's no-retreat order it gave up Kalinin on 16 December and fell back fighting through Klin country toward Rzhev, where it would hold the notorious salient for another fifteen months. Model took command in January 1942 and turned retreat into elastic defence, pulling back to the Gzhatsk line in the spring; the army's survival preserved the Rzhev salient, from which Germany would threaten Moscow for another fifteen months. Strauss was replaced by the defensive specialist Model in January 1942, who stabilised the line within weeks. The tracks recorded here are schematic headquarters-area positions, not surveyed front lines.
