Mikhail Tukhachevsky planned to encircle and surround Warsaw by crossing the Vistula River, near Włocławek, to the north and south of that city, northwest of Warsaw, and launch an attack from the northwest. With 24 divisions in four armies under his command, he planned to repeat the classic maneuver of Ivan Paskevich, who in 1831, during the November Uprising, had crossed the Vistula at Toruń and reached Warsaw practically unopposed, crushing the Polish uprising. This move would also cut the Polish forces off from Gdańsk, the only port open to shipments of arms and supplies.
