During August 1943, rumors circulated in Theresienstadt of a resumption in deportations. On 3 September in the "Daily Orders" of the Jewish self-administration, it was announced that 5,000 people would be deported three days later—the largest number so far on a single day. Unlike previous transports, the selection was not done by the Transport Department of the Jewish self-administration, but by SS commandant Anton Burger directly. Prisoners who had previously held exemptions from deportation, such as the "Aufbaukommando", the work detail that arrived at Theresienstadt first, as well as 150 members of the disbanded Ghetto Guard were included on the transport. The bulk of the transport consisted of young Czech Jews whom Himmler feared might organize an uprising inside the ghetto, as had already occurred in the Warsaw Ghetto, and their families. The transport was almost entirely Czech; out of 5,000 deportees there were 124 German, 83 Austrian and 11 Dutch Jews. Previous transports had departed to an undisclosed location in the "East", but in this case the Jews were told that they were to be sent to Birkenau to establish a work camp supposedly called the "Arbeitslager Birkenau bei Neu-Berun". Leading figures in the self-administration, including Leo Janowitz, secretary of the Council of Elders, and Fredy Hirsch, deputy leader of the Youth Welfare Office, were included in the transport to help govern the new camp.
