This new book in the popular Polish Wings series describes and illustrates the Avro Lancaster I/III bombers used by Polish pilots in Britain from 1941 to 1945. On 1 July 1940, the No. 300 Polish Bomber Squadron was created as the first Polish unit at RAF Bramcote, as a part of the Polish Air Forces in Great Britain. As there were a large number of Polish airmen, often with experience in combat against the Germans from Poland and France, additional bomber squadrons were created by 24 July.
