"those of the Fourth") who repelled several waves of enemy infantry and cavalry charges, holding the burning town during heavy fighting in close quarters.

[8] The danger, according to the commanding officer of the Polish Cavalry Brigade, General Karol Turno, was in being trapped and pushed into the river as occurred in the Battle of Berezina.

[11] The Polish headquarters were moved to Kruki, further to the west, on the Omulew River, a tributary of the Narew[12] Skrzynecki ordered Bogusławski to "defend the town to the death" with mainly the 4th Infantry Regiment and two batteries of four cannons each.

[16] The constant cannonade caught buildings on fire, forcing the inhabitants to flee into the streets and market where the battle was raging and "Ostrołęka would begin more and more to resemble hell".

[18] By now, Karl Wilhelm von Toll had 62 guns sweeping the valiant Poles and Diebitsch ordered the Astrakhan Regiment to cross the river using boards from the Ostrołęka homes to repair the damaged bridges.

[23] At 19:00, Lt. Col. Józef Bem and Henryk Dembiński manoeuvred to make the Russians think the Poles still had hidden behind the hills reserve forces which would cost Diebitsch dearly if he continued to advance.

[25] The effect of Bem's "terrible shots" was to cut out the ranks of grenadiers in the streets, and the impression on Diebitsch was enough that he withdrew most of his troops from the bank of the Narew under cover of darkness.
