Undersea Warrior: The World War II Story of "Mush" Morton and the USS Wahoo

Rate this book
No man above or below the waves was as admired-or feared-as this determined naval commander...

Among submariners in World War II, Dudley "Mush" Morton stood out as a warrior without peer. At the helm of the USS "Wahoo" he completely changed the way the sea war was fought in the Pacific. He would relentlessly attack the Japanese at every opportunity, going through his supply of torpedoes in record time on every patrol. In only nine months, he racked up an astounding list of achievements, including being the first American skipper to wipe out an entire enemy convoy single-handedly.

Here, for the first time, is the life and legend of a heroic, dynamic, and ultimately divisive submarine commander who fought the war on his own terms, and refused to do so any other way.

Mush Morton , never heard of him until Janruary . This guy was insane , the good insane, the brave insane, the kind of insane that mesmerizies people and causes them fight to the death for you .

He was a hero in the true sense of what a hero is . He set the trend in submarine warfare aganist Japan , this one guy in my opinon contributed more than any one single man during WW2 towards ending it .

“Undersea Warrior” by Don Keith, published by Caliber.

Category – Military/World War II

This book is about the “Silent Service”, and the exploits of a daring Naval Officer and his submarine, the USS Wahoo.

The Japanese bombing at Pearl Harbor awakened a sleeping giant, until this time submarines were used mostly for coastal patrol and reconnaissance; they very seldom actively engaged the enemy.

After Pearl Harbor a young and brash naval officer, Dudley “Mush” Morton changed the entire role of the submarine service. He and his crew actively took on the enemy and were responsible for some of the more daring exploits during World War II. Mush was the first to use a “head to head” shot, firing a torpedo at a ship coming directly at his sub. He was adamant in his condemnation of faulty torpedoes, and several times thought he had ended his naval career due to his outspoken criticism.

Mush also had a deep hatred for the enemy. He was considered a criminal by some of his colleagues when after sinking a Japanese ship, instead of picking up survivors, he ordered them shot. This led to some thinking that he was a madman.

Even with all the controversy surrounding him, he was loved by his crew and all of his officers went on to stellar careers in the submarine service. One of his officers, Dick O’Kane, led the most successful patrol of World War II.

Mush is remembered at the Naval Academy and several other Naval Installations by having buildings named after him. He single handedly changed the way of submarine warfare in the Pacific.

A fascinating book, especially for those who served in the Armed Forces, but even more so for those who served and serve aboard submarines.

It's now October 10, 2018. I read this book back in August of 2015 (guess that was before I was really using GoodReads?) Here's the brief review I wrote on Amazon back then:

"A very readable account of Mush Mortan and the USS Wahoo. The author did not at all attempt to sugar coat Captain Mortan's action in going after what he perceived to be Japanese soldiers escaping one of the ships he had just sent to the bottom. Unfortunately, some of those "Japanese soldiers" were actually prisoners of war being moved for use as slave labor. In today's world, many would look at Captain Mortan as a war criminal for this incident. Personally, I have mixed emotions on this, especially asI have a Merchant Marine background But taken in the context of what was going on in WW2???"

When I wrote that review I was forgetting about the Peleus affair.

A German U-Boat commander and several of his officers were tried and executed for machine-gunning survivors of the freighter Peleus.

A novel I'd read back in high school, and then actually re-read in 2014 was based on the Peleus affair. It was "An Operational Necessity" by Gwyn Griffin. I don't recall the title, but I've also read a non-fiction book on it.

Fairly comprehensive overview of the career of one the more famous United States' submarine "aces" from World War 2.

The most interesting question the book left me with (and let me be clear, the author does not overtly advance this question) is this- Was Mush Morton's successes due more to his near fanatical "kill the sonza bitches" tactics, or the skill of the men who served under him in the attack party and who would go on to become successful skippers- Dick O'Kane, George Grider, etc. Again- not a question that is actively kicked around in the book, but one that I began to mull over as the book came to a close.

Overall, a very enoyable and quick read.

Well Written Biography

I found this to be a well written biography of a World War II submarine skipper who re-wrote the rules for submarine warfare in the early days of the Pacific war zone. Older and conservatively trained captains were pushed out in favor of more aggressive skippers. Mush Morton was one of them and he had an exemplary record aboard the Wahoo. If you are a fan of this period of history, this book will please.

What a great book! Really enjoyed reading this after having read a book about the family search for the downed sub. I have read so many histories about how the torpedoes used during this stage of the war cost commanders so many lost targets and so reading the frustration aboard one of the most notorious “killer” subs of the era was incredibly interesting. Also reading why it is believed that “Mush” did not get a Medal of Honor was interesting and still could be considered debate worthy. Overall a very good read that did not overstay it’s welcome. Highly recommended.

An excellent book; well-written, good documentation and sources, little to no speculation. The only concern I had with it is that it doesn't seem to know exactly what it is. It's not a biography of CMDR Morton, and it's not a history of the USS Wahoo. A wide variety of problems are brought up - but no resolution is given (certainly that's because, in some cases, there was no resolution).

I'm glad he included information on the search (and the finding) of the Wahoo; good closure and very meaningful. Once again, however, he only lightly touches on the details.

I had read the Logs of the Wahoo before and they are more robust and exciting than the "Undersea Warrior" writing of Mush Morton's odyssey. The book is written, I suspect, for those who have not done any research on the Wahoo's history. The book points out, and the logs, the disillusionment and real animosity directed toward the torpedos, and the politics involved, that they were required to use. History, covered well, is to me, is necessary to enable one to look at the present and see some of what lies ahead in our future.

Keith isn't enough of an historian for my taste. On the whole not a bad read, especially for those with a particular interest in WWII submarine warfare on the American side of things, and in Morton in particular. That said, the tone was a bit too casual and more playing to the audience, again those with a bent towards this sort of thing and, in addition, Navy vets like myself who seem to have an above and beyond fascination, than to honest-to-God history.

Great topic, poorly written. This is the story of WWII submarine officers and operations, with a good sub-plot (sorry for the pun) about innovative thinkers overcoming institutional conservatism. But the author uses juvenile language ("...the sonarman listened furiously") and often fills in gaps with his own speculation. And he does not appear to understand submarines.

An excellent telling of Wahoo 's story

Previous studies of Mush Morton and the Wahoo focus on the ten months of their patrolling and end in mystery. This book tells the story of Morton's life and how the story ended with the discovery of the wreck. Dad but you get a feeling of closure

A great story filled with adventure and history. This is one of those books you are happy to have discovered hiding on your bookshelf. Definitely an exciting read for anyone that is interested in history, especially about submarine warfare in the Pacific theater during World War 2.

Inspiring

A true account of a submarine commander who truly honored his personal insights. Mush Morton revised the way submarine warfare was conducted. While I wish there was no need for warfare there will continue to be. The courage and command style are important facets of Morton’s legacy. Told eloquently, this is an important read for anyone interested in lessons to be learned from people who answer the call to defend their country.

A Submariner’s Tale - Required Professional Reading

I have always lived in awe and solemn respect for the men who served on WWII era submarines. There service and sacrifice is right up there with those veterans who stormed ashore on D-day.

As a modern nuclear submarine driver, I lived and served during the Cold War years. I have read many fine books on WWII submarines escapades and this one is one of the best. It is for both layman and expert. I’m sure you will enjoy it too!

A spine tingling, thoroughly researched and well written biography of Dudley W. (Mush) Morton and his war patrols as skipper of the submarine USS Wahoo, one of the most successful submarines in the Pacific in WW-II. As Veterans' Day 2023 approaches on November 11th, it was a solemn of the debts we owe to our military veterans and of the sacrifices they and their families made over the centuries of our existence as a representative democracy.

Great read!

Recommend this book to any navy and/or war historian. The reading of this fine book stroked my patriotic spirit and brightened my admiration and appreciation for these and many others that have died and served to keep this great nation safe. The task our servicewomen and men are conducting on foreign and domestic soil is unbelievable. thanks to all!

Great book...my 2nd by this author. True account of a WWII submarine commander. Morton is credited with changing the way submarines are employed and this is his story. Well researched and detailed I like the way that he describes naval traditions, like the wardroom so that non naval people may understand.

What makes a man (now women too can serve on submarines) this biography explores the world of Commander Dudley W. Morton, AKA Mush Morton, the man who was feared by the IJN and for good reason. His patrols with Richard O'Kane is legendary. This biography explores this man's life and I wish there were more books about him.

I was glued to this and failed to notice...

This book is a true page Turner. My wife got stuck in the chicken coop and I was mesmerized and failed to notice. That is the power of a good book, well written and easy to get in the moment with the subjects the author presents.

Really enjoyable account of one of the most colorful and dynamic submarine skippers of WWII. Ready to engage the enemy when requires, sometimes using unorthodox methods, he was one of the best. I would love to have gone to sea with him.

A great telling of a story that we would not know about if not for the authors for sight in sharing. "Mush" Morton refined submarine warfare and helped lead the way for victory in the Pacific theater of WWII.
