Of course, most people reading the book would have a rough idea of what happened once Hitler got power in 1933 - the Berlin Olympics, the Anschluss of Austria, the alliance with Stalin, the attack on Poland, the Second World War...and so on until Hitler's own death in 1945. But even on this 'familiar ground,' Toland unearths several gems. The most striking of these are Hitler's relationships with his generals and associates, which you can literally see changing as he starts playing a bigger role in key military decisions - everyone hails him as a genius when he succeeds initially, but as things start to go wrong, he is seen as a madman who does not understand what he is doing, and in the end as a liability as most people try to work out their own escapes, leaving him with the loyal-till-the-end Goebbels and a few others.
