Frances Zatz describes the Polish Home Army's uprising in Warsaw, Poland in August 1944, which was spurred by the belief that Soviet forces across the Vistula River would liberate them. The Soviet army did not intervene, leaving the Warsaw inhabitants to defend themselves against heavy German fire. Among Warsaw Rising fighters were Polish Jews who survived Warsaw Ghetto Uprising that took place a year earlier. Some of them were prisoners of Gesiowka Concentration Camp liberated by Polish Home Army at the very beginning of the Risin, on August 4th, 1944.
