After the initial ambushes worked (Battle of Mokra), the Germans gained momentum and easily defeated the rear units of the Łódź Army (still in the process of mobilization).

Because Łódź had fallen, the victorious tank brigade and the supporting infantry soldiers had to withdraw from Piotrkow Trybunalski.

This exposed the flank of the Kraków Army and they and the fully mechanized 10th Cavalry Brigade of Stanislaw Maczek had to head towards Lvov.

All of Poland fell completely under the control of Nazi Germany, the Soviet Union and the Slovak Republic on October 6, 1939.

Munitions and uniforms were manufactured in the newly established Ghetto Litzmannstadt by Jewish slave labor.

Jews from Poland, Germany, Benelux and Czechoslovakia as well as Roma people from Austria were brought to live and work there in appalling conditions.
