August 1942 saw the creation of the Pathfinder Force. Its task was to mark targets for the groups of bombers which followed them with a precision that called for reckless heroism. Between 1939 and 1945, Bomber Command suffered no less than 55,888 fatalities from a total of 100,000 men. In this book Michael Wadsworth describes the air war in Yorkshire, and the young men who flew night after night against desperate odds.
