Some families committed collective suicide to avoid the inevitable. The deportations slowed down, for a time, only after the purge of the ghetto was completed. Some 89,446 able-bodied prisoners remained. In October, the number of German troops was reduced, as no longer needed. The German Reserve Police Battalion 101 left the ghetto to conduct anti-Jewish operations in Polish towns with direct lines to Treblinka, Bełżec, and Sobibór. Meanwhile, a rare camp for the Christian children between 8 and 14 years of age was set up adjacent to the ghetto in December 1942, separated only by a high fence made of planks. Some 12,000–13,000 adolescent Poles with parents already dead went through the Kinder-KZ Litzmannstadt according to International Tracing Service. Subjected to a selection process for Germanisation, the 1,600 children performed work closely connected with the industrial output of the ghetto, with help and advice from Jewish instructors. Since late 1942 the production of war supplies was coordinated by the autonomous German Management Board (Gettoverwaltung). The ghetto was transformed into a giant labor camp where survival depended solely on the ability to work. Two small hospitals were set up in 1943, nonetheless hundreds of tormented prisoners died each month. In April 1,000 Jews were transferred to labour camps in Germany. In September 1943 Himmler ordered Greiser to get ready for a mass relocation of labour to the Nazi District of Lublin. Max Horn from the Ostindustrie arrived and made an assessment, which was damning. The ghetto was too large in his opinion, badly managed, not profitable, and it had the wrong products. From his perspective the presence of children was unacceptable. The relocation idea was abandoned, but the immediate consequence of his report was an order to reduce the size of the ghetto. By January 1944, there were around 80,000 Jewish workers still subsisting in Łódź. In February, Himmler brought back Bothmann to reinstate operations at Chełmno. Camp for Polish children On 28 November 1942, a camp for Polish children was opened. The official name of the camp was "Security Police Litzmannstadt Isolation Camp for Polish Youth" (), however, the camp was referred to as the Camp on Przemyslowa Street. The camp housed children aged 8–16 who were orphans or accused of criminal activity such as theft. Over 1,000 children lived there, separated from their parents, working eight hours a day. They were fed starvation rations and had no access to
