Controversial it may have been, but it was the only way for Britain and the Allies to carry the fight to Germany in the early years of the war. It turned out to be one of the most costly theatres in the entire conflict. It is an amazing story of selfless courage and sacrifice as Britain at War hears from the men who flew in the Lancasters and the Wellingtons. Their memories provide a chilling but fascinating glimpse into a world in which every man depended on each other to get home safely.
