29th Infantry Division (Poland)

It consisted of these units: In August 1939 the Division, under Colonel Ignacy Oziewicz, was transferred to the reserve Prusy Army of General Stefan Dąb-Biernacki.

At that moment, commandant of the Prusy Army, unaware of the situation, was planning to counterattack the Germans, which was supposed to take place on the night of September 5–6.

However, on September 5, at 9 pm, commander in chief of the Polish Army informed him to withdraw north of Piotrków Trybunalski.

This order did not reach all Polish units, and the 76th Lida Infantry Regiment attacked the Germans, managing to capture a village.

After bloody skirmishes, most Polish soldiers died, those who survived retreated to the forests in the area of Koło.
