Not only is his writing good but his research is extensive and accurate. He weaves a story that shows the compassion and dedication of the silent service. This is a must read for anyone interested in submarine warfare!” – Jared (Hawaii, US) “I read just about any WWII history book I can get my hands on, be it navy, army, air corps or marines. This is one of the best I've read on submarines. The selflessness of this and all brave crews living in cramped, smelly, over heated tin cans is amazing. I doubt I could ever do that. I’m amazed at the sacrifice and courage of these men. The author really puts a face to the battles that happened under the water, securing the seas for the victory of the allied forces. Simply wonderful!” – Anna (Minnesota, US)
