I'll try to find that book, but it is not easy here, in Czech Republic.
(btw., are there in that "Stalin's folly" some numbers? I mean division numbers and figures about their mannpower and equipment, especialy the tanks?)
A little off-topic: Right now I'm reading some very strange book about Barbarossa. It's name is "Thunder on the Dnepr" from Bryan Fugate and Lev Dvoreckij and I must to say, I have never ever seen such great pile of nonsenses, as is there. According to authors, all of those great defeats of Soviets up to winter of the year 1941 were purposely prepared by Zhukov and, but only partially, by Stalin and Timoshenko to lead Germans to the depth of Russia, where they will be more vulnerable etc.... Oh, man, if you can, try to borrow copy of this fairy tale, just for fun, but never, never spend your money for it. I have to say, that the last two books from Suvorov (from the years of 2002 and 2005) were much better (if possible, of course), than this Thunder... Interesting is, that authors are often using the very same affairs or doings like Suvorov, but they are turning them to contradictory evidence, often by concealment of some facts etc...
