The Russian forces, under the command of Ivan Shakhovskiy, included 11,000 men and 56 cannons. Their orders were to march through Białołęka and to continue to Brodno. Polish forces under the command of Jan Krukowiecki, Antoni Giełgud and Kazimierz Małachowski were in fortified positions to protect the entrance to the capital city. Their combined forces included 13,000 men and 22 cannons. These forces included 2,700 cavalry and 1,200 infantry under the command of Antoni Jankowski.
Battle
The Battle of Białołęka lasted two days. After the first day, the Polish had lost 450 men, while the Russians had suffered 650 losses. During the second day, Polish forces suffered 320 losses, while the Russians suffered 430. In total, 670 Polish soldiers were killed or wounded, compared to 1,070 Russians. Fighting commenced on February 24 at approximately 09:00 AM. Russian troops attacked the combined forces of General Kazimierz Małachowski and Antoni Jankowski, who had taken positions within the town and surrounding woods. Russian forces attacked the Hussars who were entrenched in the forest, and suffered heavy losses. After many hours of fierce fighting, the Polish forces were pushed back from their position and into the countryside. The Polish high command sent Antoni Giełgud to reinforce Małachowski and Jankowski, and ordered Jan Krukowiecki to take charge of the Polish forces at Białołęka. The reinforcements arrived at the battlefield just before sunset, and skirmishing continued through the night. Suspecting that Krukowiecki's forces were vastly outnumbered, Polish military authorities ordered their forces to hold their positions, and to only retaliate in the event that the Russians attempted to press on towards Warsaw. Ironically, Shakhovskiy received similar orders from Field Marshal von Diebitsch: if attacked by Polish forces, he was to withdraw immediately. Shakhovskiy withdrew to the town of Marki directly to the east, and was pursued by Krukowiecki, whose flanking maneuver threw the Russian forces into disorder. The Polish forces were able to take back Białołęka, but the disorganization of the Russian forces made it impossible to strike a decisive blow.
Aftermath
By February 24, the Russian Army had reached the outskirts of Warsaw in two columns: one from the North under the command of General Shakhovskiy, and one from the East under the command of General Grigoriy Vladimirovich Rosen. Field Marshal von Diebitsch initially planned a full frontal assault on Warsaw to take place on February 26. The successful Polish counter-attack at Białołęka, however, prompted von Diebitsch to change his plans and attack earlier. On February 25, General Rosen received orders to attack, resulting in the Battle of Olszynka Grochowska. His forces were joined later that day by the remnants of Shakhovskiy's defeated column.
