Franz was promoted to Untersturmführer (Second Lieutenant) and became an appointed official on 21 June 1943 on the orders of Heinrich Himmler . On 2 August 1943, Franz along with four SS men and sixteen Ukrainians went for a swim in the nearby Bug River , which depleted the security at Treblinka significantly and helped to improve the chances of success of the prisoner revolt that took place at the camp that day. After the revolt, the camp's commandant Franz Stangl left. Kurt Franz served as his replacement, and he was instructed to dismantle the camp and to eliminate every trace of evidence that it had ever existed.  Franz had at his disposal some SS men, a group of Ukrainian guards and about 100 Jewish prisoners who had remained after the uprising. The physical work was carried out by the Jews during September and October 1943, after which thirty to fifty prisoners were sent to Sobibor to finish dismantling there, and the remainder were shot and cremated on Franz's orders.
