 The senior Japanese officer at the camp was Lieutenant S Kamikubo of the Imperial Japanese Navy.The prisoners consisted of two groups; the larger group were Koreans and members of forced labour units who had been working at Henderson Field (Guadalcanal), and the smaller group consisted of about 240 officers and other ranks of the Imperial Japanese Army and Navy (including Airmen from both branches).About half of this second group were crew from the Japanese cruiser Furutaka, which was sunk during the Battle of Cape Esperance.
