The sound of the nearby battle made Field Marshal Dybich change his plans and order an assault on Polish positions 24 hours earlier than planned. At noon the I Corps and the Corps of General Grigoriy Vladimirovich Rosen were ordered to assault the Polish 2nd and 3rd Infantry Divisions (Generals Skrzynecki and Żymirski, respectively) in the woods east of Grochów. At the same time the Corps of General Pahlen was ordered to outflank the Poles from the south and strike through the lines of the Polish 4th Infantry Division of General Szembek.
