Publisher Desc.  On October 14, 1943, at the death camp of Sobibor, underground resistance succeeded in covertly killing eleven German officers and a number of Ukrainian guards. Of the 600 inmates in the camp, roughly 300 escaped, although most were later re-captured and killed. The escape forced the Nazis to close the death camp. They dismantled it, bulldozed the earth, and planted trees to cover it up.
