The Channel Islands Occupation Society (CIOS) is a voluntary organisation that seeks to study all aspects of the German occupation of the Channel Islands and to raise awareness and educate the public about the occupation during the Second World War. There are two branches, one in Jersey and the other in Guernsey, that take turns in publishing the Channel Islands Occupation Review. The CIOS manages many German fortifications and archives on both islands.

Guernsey Branch

Founded in 1961, by Richard Heaume, M.B.E.,in Guernsey, the society still researches all aspects of the German Occupation of the Channel Islands. It has an archive of historical documents, and also renovated the former German naval Signals H.Q, which was responsible for all messages to the islands from France and then Germany after D Day. The Guernsey branch is a member of the Association of Guernsey Charities, and donates money every year to The British Red Cross, in recognition of the help given to islands by the International Red Cross in 1944 and 1945, with supplies of food to the local population.
