The Crucible of War 1939-1945 The Official History of the Royal Canadian Air Force, Volume III Brereton Greenhous, Stephen J. Harris, William C. Johnston, and William G.P. Rawling Some 40 per cent of RCAF aircrew who served overseas during the Second World War did so in RCAF squadrons. This is their story. The first squadron to see action was No l Fighter Squad ron, later to be No 40 l, which after l 8 August 1940 participated in the Battle of Britain. The last squadrons in service were Nos 435 and 436, de livering supplies in Burma until late August 1945· In the intervening years, RCAF squadrons served in all the major commands and in most major theatres of war. They were engaged by day and by night in air-to-air combat, strategic bombing, photo-reconnaissance, anti-shipping strikes and anti-submarine patrols, close air support, interdic tion, and tactical airlift supply. The Crucible of War is divided into five parts: Air Policy, the Fighter War, the Maritime Air War, the Bomber Air War, and the Air Transport War. The authors break new ground by demon strating the influence of senior RCAF officers in shaping the execution of Canadian air policy, and they show how senior RCAF officers were permit ted to determine the pace of Canadianization of the RCAF. Many operations are described in detail from a wide variety of documentary sources, among them the unsuccessful battle of attrition that resulted from Fighter Command's offensive over France in 1941-2, and the actions of the RCAF's No 83 Group in Second Tactical Air Force, which pro vided air support for the British Second Army. Overdue notice is accorded the anti-shipping strike squadrons of Coastal Command. No 6 Group's battle with German night-fighters is re counted within the framework of complex elec tronic measures and counter-measures developed by both sides. The RCAF, with a total strength of 4061 officers and men on l September 1939, grew by the end of the war to a strength of more than 263,000 men and women.
