This is a hardback book, newly-published, running to over 430 pages (though some 85 pages are notes, index and acknowledgements), subtitled
From the Beaches of Sicily to the Gates of Dachau. The back cover tells us:
"No World War II infantry unit in Europe saw more action or endured worse than the
one commanded by Felix Sparks. A maverick officer - and the only man to survive his
company's wartime odyssey from bitter beginning to victorious end - Sparks's remarkable
story has never before been told."
I have to point out this the story is of an American officer and I have not bothered to check whether the claims made in the previous paragraph hold true for all allies (somehow when we include Germany and Russia, I doubt it). For a start, the mathematicians will have noticed that 500 days is well short of two years. However this does not detract from the book as it stands once allowances are made.
