First published in 1993, this accomplished history of Royal Air Force Bomber Command 4 Group has been unavailable for many years. The group will be forever associated with Yorkshire, where it was based for 11 years from 1937 to 1948. The core of the book focuses on the tremendous efforts made by the squadrons allocated to 4 Group during World War II. Backed by hard-working and loyal ground crew, night after night, many hundreds of brave young men flew off into the unknown in Whitleys, Wellingtons and Halifaxes to bring retribution to the Third Reich. Aircraft from 4 Group were the first to fly over Berlin, much to the embarrassment of Goering. They were also the first to bomb Italy. The casualty rate was horrific, especially in the early years of the war when a bomber crew rarely completed a full tour of 30 operations. Interest in the men, machines and operation of RAF Bomber Command has always been considerable.
