The Zośka Battalion fought in the most difficult areas of Warsaw throughout the uprising. At the beginning of August 1944, Zośka was stationed in the Wola district, where, after early successes by the insurgents, which included the liberation of 350 Jews from the Gęsiówka concentration camp, the Germans launched their first major counter-offensive of the uprising (and also committed some of their worst atrocities - the Wola massacre). After 11 August, when Wola fell, Romocki and the entire Zośka Battalion relocated to Warsaw Old Town ("Starówka" or "Stare Miasto" in Polish), where they fought valiantly for the next three weeks.
