Max Horn believed that Jewish forced labor was the way of the future , but his plans were halted by the Warsaw and Białystok ghetto uprisings , the latter of which occurred where the '' Ostindustrie '' textile and armament factories were scheduled for relocation . In the wake of the uprisings , and with the war on the Eastern Front increasingly turning against Germany , the SS decided to eliminate Poland 's remaining Jewish forced laborers to prevent further unrest . On 3 November 1943 , Osti 's workforce was liquidated in its entirety in the course of '' Aktion Erntefest '' , the single largest German massacre of Jews in the entire war , with approximately 43,000 victims across District Lublin being shot in fake anti-tank trenches . Subsequently , Horn complained in a report to Globocnik about the outcome of '' Aktion Erntefest '' ; he stated that it had made Osti " completely valueless through the withdrawal '' sic '' of Jewish labor " . The company became officially defunct in March 1944
