I discovered this book in the library as I was searching for books whose titles start with the letter X and I'm glad I did.
World War II continues to amaze me because even though the entire thing lasted less than 6 years, there are so many fascinating stories that happened all over the place. The story of the midget subs dubbed the X-Craft is one of those.
One of the biggest, baddest battleships in the German navy was the Tirpitz (named after Admiral Von Tirpitz), and so fearsome was the ship that it terrorized the entire northern ocean. Not only did it have some of the most powerful guns of any ship at the time, it was also throughly armored like a floating tank, and had blistering speed, so it could make lightning raids against ports and ship convoys, devastate them without fear of being damaged, and make an escape before any defenses could be brought to bear.
The British had to maintain numerous ships and aircraft carriers in the North Atlantic just to guard against this one ship, and those ships were desperately needed in the Pacific. So the British admiralty and Churchill made sinking the Tirpitz one of their highest priorities.
The Tirpitz was so well protected that attacking through conventional means couldn't hope to succeed. It was anchored in a remote Norway fjord, in a bay protected by destroyers, mines and numerous gigantic anti-submarine nets, overlooked by a small fishing village dominated by the Nazis and patrolled by the Gestapo. The overland approach from the south was a trackless arctic desert, and the hills around the fjord offered excellent sight lines in every direction, with anti-aircraft emplacements surrounding the area. Attacks by air, land or sea would be seen miles away and easily repulsed.
Thus was hatched the idea of using midget subs, crewed by four men, to sneak in under the numerous defenses of the anchorage, drop massive bombs to the bottom of the harbor in order to hit the Tirpitz in its most vulnerable spot -- directly underneath -- and then get away undetected.
Things don't go as planned.
This is a terrifically exciting story, full of twists and turns, setbacks and freak accidents and fortuitous turns of fate. I couldn't help thinking what an amazing movie this would make. It's so tense in some spots that I was torn between eagerness to find out what happened next and not wanting to know, lest my worst fears were realized. I think that feeling was heightened by the fact that this is a true story, which always raises the stakes.
Gallagher did a thorough job of researching this raid, including going over the ships' logs and interviewing many of the surviving combatants. (The edition I read was the original hardcover from 1969, so it was written some 26 years after the events.) There are so many interesting little tidbits that he uncovered, such as the fact the mini-subs were too small to use typical naval equipment, so they had to improvise. One such improvisation was using the same four-cylinder Diesel engines which powered London's double-decker buses. Not a great solution, but the best one they could come up with given the time constraints. They had to design, build, test and launch the operation as soon as possible, which meant the subs had to be designed and built in just a couple of months. That kind of thing always amazes me.
Not only were the technical aspects fascinating and the raid itself nail-biting, but the characters of the young men who volunteered were an incredible mix of personalities.
I think stories like this are amazing for all those reasons. I really want to see James Cameron make a movie about this.
