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 1 April 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.
