After the disaster of July and the death of Yitzhak Wittenberg, many of those in the underground decided to flee the city. The German entry into the ghetto was a surprise and there was no time to organize. Forty fighters led by Yechiel Scheinbaum fought until they were all killed. Around 200 more left the ghetto and joined the partisans. A second Aktion on September 23 marked the end of the ghetto.
