The revolt began upon the German announcement of mass deportations from the Ghetto. The main objective was to break the German siege and allow the maximum number of Jews to escape into the neighboring Knyszyn (Knyszyński) Forest. A group of about 300 to 500 insurgents armed with 25 rifles and 100 pistols as well as home-made Molotov cocktails for grenades, attacked the overwhelming German force with a great loss of life.
