How far to press the advantage?

Joseph Stalin, head of the Soviet State and the Stavka

summoned his generals to the on 5 January 1942 with a conviction that brooked no argument: the counter-offensive launched in December had pushed the back 150 to 200 kilometres from Moscow, and that momentum had to be exploited without delay. The was, in his view, on the verge of collapse along the entire Eastern Front, from in the north to Crimea in the south, and the moment called for a killing blow, not caution.

, who had just directed the defence of Moscow, took the floor and challenged that picture. Soviet reserves were thin, divisions exhausted, supply lines stretched to breaking point. Rather than scattering available forces across 1,500 kilometres of front, it made far more sense to concentrate all reserves against Army Group Centre alone, still reeling and vulnerable at the heart of the German line. Other voices proposed a third course: consolidate the gains of December, rebuild reserves in men and equipment throughout the winter, and launch a major offensive only once the was genuinely ready.

Stalin ruled without appeal. He could unleash a general offensive across every front simultaneously, crush the before it recovered, and thereby shorten the war by an entire season. Reserves would be spread across all sectors, and the armies would advance everywhere at once. Zhukov recorded his disagreement but complied.
