This book single-handedly introduced the vast majority of all tank-related WWII myths into modern culture, and it seems now to be impossible to dislodge it from its place of infamy.
The recent movie "Fury" used this debunked atrocity as a source, in order to attempt to make the movie more accurate - anybody knowledgeable about WWII tank warfare will attest to the absurd results. :/
The book - published by a major publisher - and boasting an introduction from the esteemed Steven Ambrose (a historian of no small stature, who himself is guilty of not understanding WWII tank warfare) starts off well enough, but VERY quickly the major flaws are revealed.
Belton Cooper has also appeared in interviews on the History Channel - a dubious source of "history" indeed.
For starters, this book has NO bibliography. It has NO endnotes. And it has NO footnotes. So, basically we are left with a book that doesn't attempt to back up what it says with ANY sources - and yet, as you can see from all the other reviews, people just take Coopers word for what he says at face value.
It is an odd book. As a memoir it is poorly written, and wanders all over the place - frequently into the realm of speculation. As a history it supplies zero sources, and thus can be accused of being psuedo-historical. And as an assessment of the M4 tank it is MAJORLY incorrect.
Belton Cooper was an ordnance officer, so he did see the end result of tank warfare from a rather unique, and grim, point of view. But this does not make him a General in regards to theories of WWII tank warfare - not even an expert. This is a conceited attitude on his part that shapes this entire volume.
He constantly gives us second-hand stories, things he heard, and has a VERY biased view towards the German army of the era - seemingly admiring the German army more than his own comrade-in-arms! He uses hyperbole a lot, such as describing a single battle he witnessed as "the most spectacular aerial battle of the war".
He also relates how he was forced to take command of an armored column, which was defending a road junction outside if Mons. He says that he has frequently pondered just how much critical weight this guard position affected the battle. Um, considering that the record shows that he faced ZERO enemy forces, the only assumption one can make is that minimal weight was lent to the battle!
Then as to his remarkably-ignorant assessment of the M4 Sherman tank: He uses a questionable, and very narrow, assessment criteria of the tank - and he frequently mis-identifies the performance info of basic systems.
He also, absurdly, states that the M4 was so vastly inferior to the German tanks as to be one of THE worse blunders of the entire war!
This book has been completely shown, by plenty of actual, respected, historians to be almost completely wrong (some of Cooper's personal recollections are a good, valid read).
A disgrace of a book, and a shameful author. I respect that he served in the forces, but that is all.
