Creation of the Legion, as this was original name of the organization, is attributed to Major Aleksandra Zagórska, who was the commander of female couriers during the Polish–Ukrainian War. During the fighting, Zagórska lost her teenage son, 14-year-old Jerzy Bitschan, who was killed by Ukrainian shells on the Lychakiv Cemetery, and about whom several songs were later written. Altogether, 66 Polish women died fighting in Lviv in late 1918.
