The book, Eagles High: The Battle Of Britain - 50th Anniversary tells the story of the men and women of all nationalities who fought in what, even before it had begun, had already been named the Battle of Britain.  This book chronicles the events leading up to this epic confrontation and then takes the reader from the opening skirmishes in the skies over the English Channel in the summer of 1940 through the darkest days in September 1940 when it seemed that the Royal Air Force (R.A.F.) could do no more, to the stunning change in the Luftwaffe's tactics from bombing airfields to instead terrorizing large population centers by bombing cities like London.  In retrospect, this change in tactics represented a terrific blunder for the German Luftwaffe in that it gave the struggling R.A.F. the time it needed to repair airfields, as well as, deploy new aircraft and pilots.  During the Battle of Britain, British, Americans, Canadians, Australians and South Africans flying Hawker Hurricanes and Supermarine Spitfires squared off against a much larger force of aircraft flown by the experienced German Luftwaffe and Italian Air Force.  Fighting over their "home-turf" and employing sophisticated radar tracking, the R.A.F. was able to defeat the much vaunted Luftwaffe and in so doing caused Adolf Hitler to permanently cancel Operation Sea Lyon, the proposed invasion of England.  In a speech made by Winston Churchill during the height of the Battle of Britain on August 20, 1940, the British Prime Minister was quoted as saying "never was so much owed by so many to so few".  This is a view that sums-up the outcome of one of the most pivotal air battles fought between the Allies and Axis air forces during World War II.  The major sections of "Eagles High: The Battle Of Britain - 50th Anniversary" are as follows: 1) Foreword; 2) The Battle Of Britain; 3) The Seeds Of War; 4) Lessons Lost; 5) The Best Flying Club In The World; 6) Spreading Wings; 7) Schneider Trophy; 8) Rise Of The Third Reich; 9) The Eagles Soar; 10) Dress Rehearsal; 11) Blitzkrieg; 12) The Phoney War; 13) The Balloon Goes Up; 14) The Lion's Roar; 15) AOC-in-C; 16) Dunkirk; 17) Respite; 18) Control; 19) Reichsmarschall; 20) Rebuilding; 21) Dowding's Chicks; 22) Gegen England; 23) The Line-Up; 24) Skirmishes; 25) Eagles; 26) Convoy; 27) Unavailing Defiants; 28) Adlertag; 29) Base Intensions; 30) The Ides Of August; 31) Manston; 32) The Fatal Mistake; 33) Tactics; 34) Armoury; 35) The Score; 36) Recovery; 37) Injury To Insult; 38) Against The Ropes; 39) Resting; 40) Out Of August; 41) Office Hours; 42) Change Of Direction; 43) Battle Of The Barges; 44) London Takes It; 45) the Ides Of September; 46) The Guantlet; 47) September Flames; 48) September Embers; 49) Autumn Missed; 50) In The Dark; 51) Post-Mortem; 52) The Chianti Party; 53) Leaning Toward Europe; 54) Retribution; 55) Glossary and 56) Bibliography.  In addition to an informative narrative, "Eagles High: The Battle Of Britain - 50th Anniversary" includes the following features: 1) 1 black and white photograph; 2) Approximately 121 color illustrations; 3) 1 Messerschmitt Bf-109 color cut-away illustration with component descriptions; 4) 1 Hawker Hurricane color cut-away illustration with component descriptions and 5) 1 Supermarine Spitfire color cut-away illustration with component descriptions.  This book is 125 pages and is in excellent condition.  The author is Peter North.  Edition published in 1990.
