On September 8 Colonel Tadeusz Pełczyński began reconstruction of the division, with two infantry regiments (77th, 86th), and some artillery, which managed to cross the Vistula. Following the order of General Dab-Biernacki, the division was renamed to the 19th Infantry Brigade. The unit took part in the Battle of Tomaszów Lubelski, finally capitulating on September 27.
