After two weeks of heavy fighting within Lviv, an armed unit under the command of Lt. Colonel Michał Karaszewicz-Tokarzewski of the renascent Polish Army broke through the Ukrainian siege on November 21 and arrived in the city. The Ukrainians were repelled. Immediately after capturing the city, some in the local Jewish militia attacked Polish troops, while at the same time elements of the Polish forces as well as common criminals looted the Jewish and Ukrainian quarters of the city, killing approximately 340 civilians. The Poles also interned a number of Ukrainian activists in detention camps. The Ukrainian government provided financial assistance to the Jewish victims of the violence and were able to recruit a Jewish battalion into their army. Some factions blame these atrocities on the Blue Army of General Haller. This is unlikely as this French-trained and supported fighting force did not leave France and the Western Front until April 1919, well after the rioting.
