“Bayly’s War is very well written…. The lessons in this book include the importance of not underestimating the enemy, and understanding and mastering new technology.” —Marine Technology 

"Bayly's War is a vivid account of this vigorous defense of Britain's trade and brings to life the U-boat battles, Q-ship actions, merchant ship sinkings, and rescues as well as the tireless Bayly, the commander at the center. An impressively researched and deftly written history that is extraordinarily well organized and presented, Bayly's War: The Battle for the Western Approaches in the First World War is an invaluable and enduringly important contribution to the growing library of World War I histories and memoirs. Nicely illustrated with a series of plate illustrations, and featuring six Appendices, six pages of Notes, a three page Bibliography, and an eight page Index, Bayly's War is unreservedly recommended for the personal reading lists of military history buffs, as well as both community and academic library World War I Military & Naval History collections and supplemental studies reading lists." —Midwest Book Review

"A well and very excitingly written description of the intense and cital activity of the Royal and, later, United States navies in the 'Western Approaches' to England during World War I, this important book reminds us of an important but mostly forgotten aspect of naval history.... An excellent biography." —Ausmarine

"We highly recommend Bayly's War on many levels. It brilliantly addresses an aspect of the First World War that has received little coverage; namely, the demanding struggle to keep a critical supply line open, and introduces the reader to a fascinating British Admiral who has largely been forgotten with the passage of time." —The Northern Mariner

"Bayly's War is an easy-to-read, fascinating account of sacrifice and bravery, shedding new light on the remarkable Bayly." —Warships: International Fleet Review

"This new book gives a comprehensive coverage to the subject of the WWI anti-submarine warfare with fresh insight—Strongly Recommended." —FIRE Reviews

"This book addresses one of the less explored aspects of the First World War, the British response to the U-boat offensives around the coasts of Ireland and in the waters off the southwest of Great Britain. Drawing on printed and documentary sources from Britain, Ireland, the USA, Australia, and New Zealand, Steve Dunn describes how the Royal Navy used aggressive patrolling by sloops and auxiliaries, armed merchantmen and fishing vessels, to deter attacks on shipping and developed decoys, known as Q-ships, to lure U-boats to their destruction.... Dunn's work is a fine piece of historical writing." —Australian Naval Institute

“Bayly’s War succeeds admirably as a theater study. The reader gets the full story of the Western Approaches. The evolution of tactics, the way the theater fit into the war effort as a whole, the experiences of personnel on the station, and especially the impact of the commander and his relations with those above and below on the chain-of-command all receive due attention.” —Real Clear Defense

“This is an excellent book, looking at one of the key battles of the First World War, making it clear just how hard fought and costly it was, and how Bayly’s men helped win this difficult and dangerous campaign.” —History of War
