Irving v. Lipstadt

13.7 My assessment is that, as a military historian, Irving has much to commend him. For his works of military history Irving has undertaken thorough and painstaking research into the archives. He has discovered and disclosed to historians and others many documents which, but for his efforts, might have remained unnoticed for years. It was plain from the way in which he conducted his case and dealt with a sustained and penetrating cross-examination that his knowledge of World War 2 is unparalleled. His mastery of the detail of the historical documents is remarkable. He is beyond question able and intelligent. He was invariably quick to spot the significance of documents which he had not previously seen. Moreover he writes his military history in a clear and vivid style. I accept the favourable assessment by Professor Watt and Sir John Keegan of the calibre of Irving's military history (mentioned in paragraph 3.4 above) and reject as too sweeping the negative assessment of Evans (quoted in paragraph 3.5).

13.8 But the questions to which this action has given rise do not relate to the quality of Irving's military history but rather to the manner in which he has written about the attitude adopted by Hitler towards the Jews and in   particular his responsibility for the fate which befell them under the Nazi regime.
