How the War Was Won
Air-Sea Power and Allied Victory in World War II

'This is a book anyone interested in the Second World War will want to read. It refocuses the story of the war away from the battlefield, to the air and the sea, and also to the transit depot, the maintenance facility, the training base. This is an imaginative, cliché-busting work which lays bare exactly when, how and where the Axis lost the war.' David Edgerton, author of Britain's War Machine: Weapons, Resources and Experts in the Second World War and Warfare State: Britain, 1920–1970

'This extremely serious book attempts to re-evaluate World War II not in terms of great battles … but in terms of production, mobility, and economics. O'Brien argues that victory or defeat in World War II must be seen during preproduction, production, and deployment … The work focuses on equipment, mobility, and détente … Especially for graduate students, professors of military history, and those generally interested in the history of Europe or the Far East. Summing up: essential.' R. Higham, Choice

'A novel, provocative, and well-written study based on extensive documentary sources on both sides of the Atlantic. Its author's conviction that 'the effectiveness of tactical air power over strategic … was the most important lesson of the war, one that remains true to this day' makes the book worth careful reading. With his emphasis on degrading an enemy's 'mobility' (perhaps a nod to Basil H. Liddell Hart's 'indirect approach'?) Phillips Payson O'Brien offers a way forward for those working on 'AirSea Battle', area access, and area denial problems in modern warfare. His work will engage and instruct historians of World War II as well as current military officers, strategists, and decision-makers.' Christopher Rein, Michigan War Studies Review

'Such a thoroughgoing revision of the history of the war will outrage many historians. … This is a brave, important and impressively researched book, and all who have written on the Second World War will have to consider O'Brien's cogent arguments.' A. W. Purdue, The Times Higher Education Supplement

'Phillips Payson O'Brien's book is revisionist history at its best: thoughtful, well grounded in secondary and primary sources, and provocative. It is a mature work, the result of several years of research and reflection. … O'Brien deserves high praise for writing a book that will force scholars to think hard about the nature of World War II and perhaps also about the nature of modern warfare in general.' Talbot C. Imlay, The Journal of Modern History
