Volhynian Cavalry Brigade

As part of the first wave of the Polish Army, the brigade was fully mobilized prior to the outbreak of World War II, and transported to the area of Łódź.

In accordance with the Polish mobilization scheme, the brigade was attached to Wiktor Thommées, Piotrków Operational Group, of the Łódź Army.

After the beginning of the Invasion of Poland on September 1, 1939, the unit took part in the battle of Mokra, where it held its ground although with heavy losses.

The following day, the entire brigade took part in a sortie towards the village of Wola Krzysztoporska and Jeżów, but were forced back after a German counter-attack.

By now the brigade, was reduced to less than 50% of its original strength, but managed to retake the village of Cyganka, and continue its counter offensive towards Choszczówka, but a German counter-attack broke its momentum and forced them to retreat.
