In early December 1918, all subunits of the Regiment concentrated in Tarnow, in order to march eastwards, and help Polish defenders of the city of Lwów, which was threatened by Ukrainian forces (see Battle of Lemberg (1918)). On December 17 the soldiers went by train to Przemyśl, and all throughout winter of 1918/1919, the uhlans fought in the area of Lwów, mainly in Gródek Jagielloński.
