Prior to the building of the Warsaw Ghetto on September 16, the eve of Rosh Hoshnna the Jewish New Year, German planes bombed Jewish quarters, flying so low there could be no mistaking the deliberate intent. 

        Warsaw came under siege. The Germans exploded ten to thirty thousand shells a day on the city. twenty-thousand Jews died. Houses, stores, buildings, workshops, and factories were destroyed. Finally Warsaw surrendered. 

        November 4, the Gestopo order that there be a ghetto built the Warsaw Ghetto. On October 12, 1940, The Germans at last issued a decree ordering to establish the Warsaw Ghetto which turned to be the largest ghetto holding up to 480,000 people at one time. The walls were ten feet high topped with barb wire. If you tried escape it would cost you your life.
Germans would set fire house by house day by day. At least third of a million were behind the walls. The Jews tolerated life in in the ghetto until they found about mass executions in Vilna and Lithuania. The Jews would make molotive cocktail handguns and homemade bombs.
