Group Captain John 'Joe' Collier DSO, DFC and Bar: The Authorised Biography of the Bomber Commander, Air War and SOE Strategist & Dambuster Planner

John Colliers war began on day one, flying Hampdens in 83 Squadron with his friend Guy Gibson, in a hunt for the battleship Admiral Scheer. By the summer of 1940 he was bombing the Dortmund-Ems Canal at low-level, then Bordeaux and the Scharnhorst at Brest, which led to his DFC and Bar.

Given command of 420 (RCAF) Squadron at 25, Collier was hand-picked to direct 97 Squadron, whose Lancasters made a spectacular debut with the 1942 Augsburg Raid. In Gibsons opinion Joe Colliers 97 was the best unit in Bomber Command. After 63 missions Collier was awarded the DSO and was selected to join the Directorate of Bomber Operations (B Ops 1) at the heart of the air war: co-ordinating with the USAAF, issuing directives to Bomber Command, and arguing for precision attacks on vital enemy industries and weaponry. In B Ops 1 John Collier was closely involved in planning the Dambuster Raid with Barnes Wallis, drafted the attack on Peenemundes V-weapons research station, and managed to delay the buzz-bomb and rocket assault on London. As target selector for the specialist 617 Squadron, he and Leonard Cheshire VC made imaginative use of Walliss Tallboy earthquake bomb. 617 were also linked to Colliers role with SOEs Blackmail Committee that gave French industrialists a stark choice: sabotage your own plant or be bombed flat.

By the time he moved to India in 1945 as Deputy Director of Combined Ops, John Collier had been involved in most of the major initiatives of the bomber war. His unpublished memoir of B Ops 1 and his logbooks and letters home give direct authority to this the first biography of this remarkable flyer, one of the most significant young RAF officers of the war.
