THIS book has been a long time in the making. During that time, I have incurred numerous debts of gratitude. A Leave Fellowship from the Canadian Social Sciences and Humanities Research Council made it possible for me to spend a year doing research in Britain, while the Academic Research Programme of the Royal Military College of Canada provided funding for several subsequent trips. Numerous individuals--J. O. Baylen, Michael Dockrill, John Ferris, Greg Kennedy, Paul Kennedy, Brian McKercher, Ian Nish, John Orbell, Donald Schurman, and Zara Steiner--have given me advice and encouragement. In particular, I would like to thank David French and Arnd Bohm: the former for reading the entire manuscript and making valuable comments on it, and the latter for helping to shrink an earlier, even longer version of this book to its present size. None of the above are responsible for what follows, and any errors of fact or interpretation are my own.

My greatest debt is owed to my family. My wife, Joan, has helped in innumerable ways. Her help and understanding make all things possible, and the book is dedicated to her. Our children, Anne, David, and Susan, are in no way responsible for what is in this book but are in part the reason why it has taken so long to write.
