Once the Bolsheviks had dealt with their internal adversaries in early 1920, they directed all their focus on Poland. Initially, the Bolshevik forces on their Western Front, stretching from Belarus, and the forces along their South-western Front from Ukraine were supposed to concentrically hit Warsaw after having reached the banks of the rivers Nemunas and Bug. Due to triumphant reports about the defeat of Poland, Lenin changed his war plan in mid-July: only their Western Front was supposed to take Warsaw and Berlin, whereas the South-western Front was ordered to march on Budapest and Vienna via Lwów. The Red offensive had begun.
