Newly-released files reveal that Hitler told Himmler "everyone has deceived me" in his last days in the bunker and said the "German people deserve to perish".
Newly-released diaries contain an account of the Joint Intelligence Committee's report on Hitler's final days in his bunker.
Dr Stephen Twigge, head of the Modern, Domestic, Diplomatic and Colonial team at The National Archives in Kew, west London says the dictator is portrayed as, "a rather depressed, demented, mad individual."
That assessment comes as little surprise, but the historian says the diaries give the world a new insight into Hitler's last days.
