The Germans were surrounding Warsaw. But the cordon was still loose enough for the shattered remnants of the Polish Army Ponzan to filter in from the forests to the north of the city. In order to ease their passage in, sorties by three regiments were launched from the Warsaw perimeter on the 19th. The Poles still had quality troops to attack with, but the light armor that accompanied them was barely adequate for hard combat.
Attacker: Polish (Elements of 60th Infantry Regiment)
Defender: German (Elements of 19th Infantry Division)
