In this unprecedented series exploring the big story of the Battle of Britain, renowned historian Dilip Sarkar investigates the wider context and intimate details of the epic aerial conflict in the summer of 1940 from all sides. In so doing, he gives due acknowledgement to the roles of Bomber and Coastal Commands in addition to the fabled Few of Fighter Command.This unique narrative draws upon a lifetime of research, the author having enjoyed a long relationship with survivors and the relatives of casualties; his innumerable interviews and first-hand accounts collated, in addition to privileged access to personal papers, providing essential human interest to this inspirational story.In this the fourth volume, _Battle of Britain: Airfields Under Attack_, Dilip continues to examine the fighting on a day-by-day, combat-by-combat basis from 19 August until 6 September 1940\. It is a period in which we saw the Luftwaffe’s bombing of the all-important 11 Group airfields intensify, culminating in ‘The Hardest Day’ of 18 August 1940, which saw both sides lose more aircraft than any other day throughout the whole Battle of Britain.The tensions and problems between Fighter Command’s 11 and 12 Groups also intensified. It was a situation that eventually led to Squadron Leader Douglas Bader criticising Fighter Command tactics, proposing the use of ‘Big Wings’, contrary to the System of Air Defence and strategy involved, gaining the support of his 12 Group commander, Air Vice-Marshal Leigh-Mallory. Given its later significance, this is investigated in depth.Through diligent research, combined with crucial official primary sources and personal papers, Dilip unravels many myths, often challenging the accepted narrative. This is not simply another dull record of combat losses and claims – far from it. Drawing upon unique first-hand accounts from a wide-range of combatants and eyewitnesses, along with Daily Home Intelligence Reports and numerous other primary sources, this book forms part of what is likely to be the first and last such comprehensively woven account of this epic air battle.
