'Tonight you are going to the Big City. You will have the opportunity to light a fire in the belly of the enemy that will burn his black heart out.' The message from Commander-in-Chief of RAF Bomber Command Sir Arthur Harris was clear. As the Second World War continued into a fifth year, the airmen of Bomber Command were to fly deep into hostile airspace and bring the war direct to the German Nazi capital Berlin. From the autumn of 1943 to the last days of winter in early 1944, during the hours of extended darkness, the bomber crews braved the flak, the searchlights, enemy night fighters and extremes of weather, to bombard the 'black heart'. Prior to the all-out campaign against the 'Big City' Sir Arthur Harris firmly believed his bomber force could break the German will to wage war, but he also prophesied that 'It will cost us between 400 and 500 aircraft'. Fighting High Publishing brings together acclaimed Bomber Command historians to tell the story of some of the thousands of airmen who failed to return from operations as part of the 1943 and 1944 Bomber Command Battle of Berlin. The authors, utilising family archives, personal testimony and records, wartime memoirs, diaries and letters, witness recollections, logbooks, and official documents, piece together the remarkable, yet ultimately tragic events surrounding the losses described.
