Lotsa books to be cited here:
The Run Silent Run Deep trilogy, RSRD, Cold Is the Sea, Dust on the Sea by Edward Beach--a post-graduate course in how to run a fleet boat. After you read and understand these you'll be as crazy as I am.
I-Boat Caoptain by Zenji Orita with Joseph D Harrington. This rare book is just outstanding if you want to understand the Japanese side of the sub war.
The Admiral's Wolfpack by Jean Noli. A Donitz-centric view of the U-Boat war. Wonderful book.
Wake of the Wahoo by Forest J Sterling. Introduction by Admiral Lockwood! My copy is totally worn out and doesn't have another reading left in it.
The Boat by Lothar-Gunther Buchheim. The Das Boot story without the sniveling Everyman who mucks up the whole movie with his "noble suffering." These were warriors, damn it, not girlie men. Yea they suffered, but not that way. The movie makes me sick. The book hits a note of unparalleled purity.
Submarines at War-the History of the American Silent Service by Edwin P Hoyt. I love this author. Silent Victory without the dryness. You won't wade through this one.
The Destroyer Killer--the true story of Commander Sam Dealey and the men of the submarine Harder--heroes of the pacific in World War II! by Edwin P Hoyt. See a pattern here? If you want to understand Eugene Fluckey you must understand Sam Dealey first.
Japanese Destroyer Captain by Captain Tameichi Hara with Fred Saito and Rober Pineau. Absolutely irreplaceable!!!!
War Patrols of the USS Flasher by William R McCants. Personally autographed by Capt McCants to my wife's grandfather from the Kraken. Why is this book not always mentioned in the same sentence as "Thunder Below?" You wonder where I get my heretical ideas?
Silent Running-My years on a World War II Attack Submarine by Vice Admiral James F Calvert. President George Bush, Admiral Nimitz, Admiral J L Holloway, and Admiral Fredrick B Warder (of Seawolf) signed on to plug this book's back cover. You don't have to buy a vowel to get a clue on whether this is worth obtaining.
Torpedoman by Ron Smith. This actual torpedoman wrote a fictional account from the viewpoint of the grunts in the torpedo room. This is not particularly well written and is more marvelous for it's unpolished grit. From the back cover, "The story moves into the real arfea of combat unique to submarines with its physical and emotional demands that challenge human endurance--where the desire to perform one's duty is in constant conflict with the desire to live. A near mutiny occurs as the crew struggles with the decision of sacrificing themselves by blindly following orders or disobeying and surviving." Yeah, it's fiction but there is reality here that no other source covers. Where in the world are you going to find this book? My copy may be one of only several dozen.
Fresh Water Submarines--the Manitowoc Story. Wooooo Hooooo! Loved this book by Rear Admiral William T Nelson.
The Last Patrol by Harry Holmes. In chronological order the story of every American submarine lost in World War II.
Threshold of Hell by Albert Rupp. The story of a crewman of the USS Grenadier, scuttled, crew captured and imprisoned for the duration by the Japanese. What was his attitude after the war? The inscription reads "To Warren Watkins/Diesel Boats Forever/Best Wishes, Albert Rupp" Captured but never defeated.
Sub Duty by Grover S McLeod. Crewman on board the Halibut, Finback and Hawkbill during the war. A great read!
I tried to list books that haven't been mentioned. All the ones previously mentioned are also excellent. You're set for a couple of years there! Get to work.:rotfl:
