Stanley Internment Camp
In March 1942, Gimson was finally sent to Stanley Internment Camp, where most British colonial officials and expatriates were interned. During the internment, the British civilian internees established the "British Communal Council", which tried in a limited way to maintain the life and order in the camp. As the highest-ranking British official in the camp, Gimson became the chairman of the council and was also responsible to negotiate with the Japanese on matters relating to the camp.
