‘James Holland is a master’ BBC History It was to be the battle to end the air war once and for all. During the third week of February 1944, the combined Allied air forces launched their first-ever round-the-clock bomber offensive against Germany. The aim was to smash the main factories and production centres of the Luftwaffe and at the same time draw the German fighter force up into the air and into battle. Big Week is the knife-edge story of bomber against flak gun and fighter, but also, crucially, fighter against fighter. Following the fortunes of pilots and aircrew from both sides, this is a blistering narrative of one of the most critical periods of the entire war. Big Week was the largest air battle ever witnessed, but it has been largely forgotten – until now.
