Dennis Winter sets out to expose and analyze a major historical fraud. His theme is the Western Front in Haig's time - from the Somme to the Armistice - and he has uncovered evidence that the documents from which other histories have been written are tampered-with and often entirely rewritten versions of the truth. For example - a daily war diary was kept by all units up to GHQ and these were often altered by the Cabinet Office and crucial appendices totally removed; cabinet war minutes were likewise rewritten, with reference to whole meetings often removed. Informal records such as Haig's own diary were also tampered with, and Denis Winter even claims to have found documents which the war's official historian thought he had deliberately destroyed in the 40s. Denis Winter's material includes minutes of missing Cabinet meetings, material removed from the war diaries, confidential reports written by military attaches and private material from archives in Canada, USA, Australia and the UK.
