Books like Hitler's War

You will not find a more detailed account on Hitler's decisions towards and during the war. You just cannot, since Mr. Irving's knowledge- the book has an insane amount of sources, most of them primary- is beyond what other historians can aim for. His ability to get in touch with important survivors of the Third Reich- many of whom would reject other historians for their one-sided views- and lay hands on unique sources (like the Goebbels' diaries) make him one of the- if not the most- fundamental historians on WW2.His later derailings don't take anything away from this masterpiece, once heralded by many journalists, but later on silenced by their politically correct intuitions.
