This is a book that seems to tell the true horror of this, the decisive battle of WWII. I would not deem it essential reading to a WWII Historian, but I would certainly recommend it to a Russian History enthusiast. Similarly, to any who beleive Russia's role in the war was not crucial, this book will certainly put them straight! A must read for those who find the Russian (and, indeed, the German) war tactics and army system's of interest. Recommended, but not light reading.
