I read that one ages ago... ...damn - gotta be about 15 years or more. It was before I discovered Irving's "less than wholesome" reputation among historians.
The only things I recall about the book are some passage about Hitler feeling optimistic about the impact of the introduction of the Jagdpanzer IV with the long 75mm gun (75mm L/71?), and Irving's now infamous suggestion that The Monotesticular Madman was "too busy running the war" or some damn thing to have known the Holocaust was happening.
I remember giving my copy to my ex's brother-in-law, coloquially (ie, secretly by me and a wee select group of other people) as "The Ukranian Nazi", for his ethnic background and peculiar "histo-political" proclivity. Interacting with him could be pretty tiresome, but it had weird side-benefits, like the copies of the 1936 Berlin Olympics commemorative books his brother - the other Ukranian nazi (what are the odds? Ukranian nazi brothers! ay yay yay...) - managed to procure somehow which I got a chance to examine.
I never did get it back from him, but I'm sure he got more out of it than me, so it's just as well.
