of 57 killed and 159 wounded. However, Polish historians Andrzej Krzysztof Kunert and Zygmunt Walkowski claim that the Red Army lost around 800 killed, missing or wounded. They also lost 19 tanks and four armored cars. Polish losses, both civilian and military, remain unknown, although Soviet records claim 644 killed and 1,543 captured (66 officers and 1,477 soldiers). The Soviet troops reported the capture of 514 guns, 146 machine guns, a mortar, and an anti-aircraft gun. One notable casualty on Polish side was 15-years old Tadeusz Jasiński who was captured throwing a petrol bomb and tied to a Soviet tank as a human shield. Aftermath After the battle, the remaining forces of the Wołkowysk Cavalry Brigade broke through the lines of the reconnaissance battalion of the 2nd Light Tank Brigade in the Battle of Kodziowce and headed for the Augustów Forest. About 300 Polish defenders of the city, including teenage boys, were murdered by the Soviets after the battle. The victims were both Polish students (20) and soldiers (30) as well as an unknown number of civilians. Poles were judged by the Soviet justice organs for their participation in the defense of the city and were reproached with the participation in the armed resistance movement against the Red Army and sentenced.
