This volume deals with the development of Britain's air defences during the years leading up to the outbreak of World War II, and the development of the system during the early period of the war, leading up to the Battle of Britain. Originally classified as secret, this report was written during the war as an internal Air Ministry history by Cecil James, a historian working for the Air Historical Branch.
