that are all names of the same unit. The regiment started as Bosniaks, attached to the Hussar regiment No. 5. The unit became independent later as No. 9 in the hussar list. In 1806 there was a regiment of Towarczys plus a bataillon of Towarczys. The later was at least partly formed from Tatares. With the reorganisation of the prussian forces the remains of these units were split into the 1st and 2nd Ulan regiments.
