Beginning of February 1945 (Patreon)

After two weeks of the Soviet winter offensive of 1945, the Red Army was confronted with a dilemma, similar to that of German generals in 1941 after the battle of Smolensk - whether to attack the enemy capital immediately and risk a possible encirclement from the flanks or to secure the flanks first. 

Like the Germans in 1941, they decided to play it safe and concentrate on securing the flanks, which postponed an attack on Berlin for 2,5 months.
