Participation in Polish September Campaign
The Brigade, commanded by General Władysław Anders, was mobilized as early as March 23, 1939 and, together with Polish 20th Infantry Division (also garrisoned in Baranowicze), was transported to the area of Sierpc and Płock. It became part of the Modlin Army, on August 8, 1939, it was moved north, to the Polish–Prussian border, near the town of Lidzbark. Its purpose was to cover western wing of the Army.
On September 1, 1939, the Brigade faced German 217 I.D. of General Richard Baltzer, west of Mława. On September 4 it organized a successful counterattack, but after Polish positions had been broken, the Brigade had to withdraw south. It was ordered to defend the Vistula river between Dobrzyń and Czerwinsk.
On September 6, 1939, General Anders was informed that his troops became part of the freshly created Warszawa Army under General Juliusz Rómmel, six days later the Brigade was ordered to attack German forces in Mińsk Mazowiecki. The assault began on September 13, together with the Wielkopolska Cavalry Brigade the Poles attacked German 11th I.D. However, without support promised by the Army, the offensive halted. After that, General Rommel ordered the Brigade to move towards Lublin, as mounted troops were of no use in urban warfare in Warsaw.
Upon reaching the area of Lublin, the Brigade became part of Northern Front, commanded by General Stefan Dąb-Biernacki. It took part in heavy fights in the Battle of Tomaszów Lubelski. In the morning of September 27, 1939 the Germans, using aircraft, artillery and tanks, managed to destroy the Brigade.
