The Royal Air Force's 11 Group played a leading role in the Battle of Britain. It included the airfields at Tangmere, Westhampnett, Kenley, Croydon, Biggin Hill, West Malling, Horchurch, Hawkinge, Gravesend, Manston, Rochford, North Weald, Martlesham Heath, Stapleford Tawney, Debden and Northolt. The most famous of 'The Few' saw action in this vital airspace over southern England, London and the Home Counties. The book will give an overview of the Battle and then go on to describe the part played by the squadrons and pilots from each base between the dangerous period between 10 July and 31 October 1940. It will include a map of each airfield as it was then and a guide to what remains and places of significance nearby that can be visited today.
