"Another masterly book from Nick Jellicoe - fascinating and stimulating covering not just the convoy debate side pieces on U-boat action accounts and technical explanations – very highly recommended."

"It surpasses previous books on this subject, many of which are in any case out of print, and can therefore be considered to fall into the essential category for a wide range of readers. This is especially so in the case of the heavy mountings that form the largest part of the text, illustrations and drawings and, since we are unlikely ever to see their like again, this book may well become the last word on the subject. I thoroughly recommend it." Read the full review [link=https://navalinstitute.com.au/29607-2/]here[/link]

“The Silent Service’s First Hero is truly a revelation. Ryan Walker’s book is one of the few histories to examine the pre-Second World War U.S. Navy submarine force, setting it apart from most submarine histories.

Readers will benefit from Walker’s thorough research, placing Henry Breault in the context of a very different time. Thanks to Walker’s exhaustive study, we now know far more about Henry Breault than simply the bare bones of his Medal of Honor citation – we know about his service in the Canadian navy and numerous other U.S. submarines, his complicated marriage, his evident leadership ability as a chief of the boat (without wearing chief’s anchors!), and even how to properly pronounce his name! Relying on sparse and often-vague documentation from over a century ago, Ryan Walker has crafted as full a portrait as we are likely to have.. Read more
