In this, the sixth of Dilip Sarkar's unprecedented eight-volume series, the day-by-day events occurring in the fourth phase of the Battle of Britain are chronicled and set within a much wide context, including the operations of Bomber and Coastal Commands and the Home Front. Renowned for his evidence-based approach, the author has returned to primary sources, the analysis arising often challenging our previous understanding and the popular narrative. In Volume 5, Target London: 7 September 1940 ? 17 September 1940, the beginning of the Blitz was explored at length. This illuminated the inescapable fact that Luftwaffe air intelligence completely failed to understand how Fighter Command was organised and controlled, nor that it was replacement pilots, not aircraft, that was Air Chief Marshal Dowding's greatest concern. Indeed, on 15 September 1940, Luftwaffe aircrews were briefed to expect but a token resistance over London from the last handful of RAF fighters ? their morale shattered when their first attack was met by over 300, the second by nearly as many. This convinced Hitler that the Luftwaffe could not achieve the aerial superiority needed for the invasion of Britain to proceed. Two days later Operation Seeloewe was postponed 'indefinitely'. Reichsmarschall Herman Goering, however, still believed that the Luftwaffe could prevail ? and so continued attacking the UK, changing tack, yet again. As London had proved it 'could take it', the Luftwaffe, whilst continuing to bomb the capital by night, now focussed its daylight attacks on the British aircraft industry. Naturally the Supermarine Spitfire factory at Southampton was a primary target; it was subsequently badly hit, with great loss of life. Other factories, in the West Country, were also targeted, and, owing to a navigation error due to cloud cover, the picturesque town of Sherborne was devasted on 30 September 1940. By that date, however, it was clear that Goering's He 111 force was unable to continue absorbing such losses and the type was exclusively switched to night-bombing ? thereby substantially reducing the German daylight bombing force. On 20 September 1940, Me 109 fighter-bombers attacked London, and going forward the next and final phase would see such attacks, and high-flying fighter sweeps, dominate the daytime arena. Such raids, though, were never going to defeat Britain, so it is fair to say that the period reviewed in this volume really did see the 'Daylight defeat' of the Luftwaffe over England in 1940 ? and the events involved are interpreted and recounted in great detail. AUTHOR: Dilip Sarkar has now written over sixty well-received books. Having enjoyed a privileged relationship with many of The Few, he is a globally acknowledged expert on the Battle of Britain, currently working on a career-topping eight volume official history for The Battle of Britain Memorial Trust and National Memorial to The Few. Described by the late Dr Gordon Mitchell, son of the Spitfire's designer RJ Mitchell, as an 'aviation detective', Dilip Sarkar did actually begin his professional life as just that ? a police detective. His evidence-based approach and ability to discover new material is well-known ? in 2023, for example, he was responsible for having Air Chief-Marshal Sir Keith Park officially recognised as one of The Few. Made an MBE for 'services to aviation history' in 2003, Dilip was elected to the Fellowship of the Royal Historical Society in 2006, achieved First Class Honours in Modern History as a mature student in 2010, and in 2024 was made both a Fellow of the Royal Aeronautical Society and member of London's Royal Air Force Club. During his long career, Dilip has exhibited and spoken internationally at such prestigious venues as Oxford University, the RAF Museum, IWM Museum, and Airborne Museum, Oosterbeek; he has worked on many TV documentaries, on and off screen, again internationally, and has an engaging presence on YouTube and Facebook in particular.
