This book is a companion to a documentary produced for PBS. Unlike television, books demand solid research, detail and well structure arguments. Like so many television companion books, this is popular history that suffers from incomplete research.
While a wide range of sources may have been consulted, the lack of a bibliography leaves the reader to consider the few titles and documents listed in the endnotes. For example, there is considerable discussion of the British Army, without any reference to any of the key secondary sources dealing with the period, let alone documents. One would have preferred more discussion on the quality of the officers corps, the fighting units and structural problems rather than the facing colours, rows of buttons and descriptions of Polish cuffs. Much would have been revealed had CO 42, the Secretary of State Correspondence for Canada been consulted. At times I was uncertain if the author was elaborating on his research to support the thesis or simply list the other authors he has dined or had drinks with.
As noted elsewhere, there are a host of errors. As with all popular histories, if you read this book, do so with care.
