On 15 July 1944 the transports paused for two weeks. On 1 August 1944 the Warsaw Uprising erupted, and the fate of the remaining inhabitants of the Łódź Ghetto was sealed. During the last phase of its existence, some 25,000 inmates were murdered at Chełmno, their bodies burned immediately after death. As the front approached, German officials decided to deport the remaining Jews to Auschwitz-Birkenau aboard Holocaust trains, including Rumkowski. On 28 August 1944, Rumkowski's family were gassed along with thousands of others.
