Today the Chung Kai camp area is the third and smallest of the CWGC cemeteries. This camp was originally occupied by mainly British POWs who worked the adjacent railway segment and made the two cuttings at Khao Poom. Later it became a major hospital camp and the majority of the graves there are of those who died in that hospital. The US POWs spent a small part of their post-TBR time there as well in 1945.
