New York City
After a season full of historically-inappropriate spy gadgetry (and almost two full seasons of teasing us with cameos in the TURN opening credits), it was truly refreshing to see one of the most famous and most bizarre inventions of the American Revolution in action on the small screen. I’m talking, of course, about the submarine Turtle, invented by Connecticut patriot David Bushnell in the 1770s.
At first glance, the real-life story of the Turtle seems too fantastical to be true. Even its very design – an odd, bulbous, wooden contraption with a small copper tower, detachable gunpowder kegs, and all sorts of hand-cranks, pedals, screws, and knobs – seems more appropriate to the world of Victorian steampunk fiction than the 18th century. It’s no wonder the Turtle has been an object of cultural fascination ever since news of it trickled into the public consciousness. Even today, you can find all sorts of Turtle paraphernalia for purchase: from t-shirts to 1/32 scale models to pre-made 3-D renderings of the 18th century submarine “ready for your game development.”
But beyond its funky quasi-steampunk appeal, there is a whole lot of historical significance ascribed to the Turtle – and for good reason. The US Navy’s historical division (a.k.a. Naval History and Heritage Command) has put together an excellent summary of the Turtle’s military achievements, which you can read in full on their research website devoted to the tiny wooden sub:
The submersible Turtle [was] the world’s first combat submarine. Named Turtle because its inventor, David Bushnell, believed the craft resembled “two upper tortoise shells of equal size, joined together,” it saw action in the first days of the American Revolution. Designed in 1771-1775 while Bushnell was a Yale College undergraduate, it embodied the four basic requirements for a successful military submarine: the ability to submerge; the ability to maneuver under water; the ability to maintain an adequate air supply to support the operator of the craft; and the ability to carry out effective offensive operations against an enemy surface vessel.
To achieve these requirements, Bushnell devised a number of important innovations. Turtle was the first submersible to use water as ballast for submerging and raising the submarine. To maneuver under water, Turtle was the first submersible to use a screw propeller. Bushnell was also the first to equip a submersible with a breathing device. Finally, the weaponry of Turtle, which consisted of a “torpedo,” or mine that could be attached to the hull of the target ship, was innovative as well. Bushnell was the first to demonstrate that gunpowder could be exploded under water and his mine was the first “time bomb,” allowing the operator of the Turtle to attach the mine and then to retire a safe distance before it detonated.
That’s quite a long list of firsts! In multiple ways, the Turtle was an engineering marvel ahead of its time. Another remarkable feature of the Turtle was its use of bioluminescent fungi as a light source. No, really! Known both then and now as “foxfire,” the phenomenon of glowing blue-green fungus found in decaying wood is documented back to ancient times, and Bushnell was smart enough to see it as a viable alternative to oxygen-sucking candle flames. (If you love ingenious details like these, then I highly recommend you check out the original description of the Turtle’s form and function as written by Dr. Benjamin Gale in November, 1775. It reads like a science fiction novel!)
The Turtle’s Maiden Mission
The fact that the American forces had a fully-functional submarine in their arsenal in 1776 is impressive enough – but on top of that, the Turtle’s wartime mission was remarkably complex, especially for an experimental piece of technology. The Turtle was conceived and built not for reconnaissance or stealthy transport, but to blow up enemy vessels by means of attaching timed underwater mines (i.e. small kegs of gunpowder with special fuses) to their hulls. Once again, from the Naval History and Heritage Command website:
Bushnell had devised Turtle as a means of breaking the British blockade of Boston harbor but because of problems with the vessel… the British fleet had departed from that harbor before Turtle was operational. The first attack on an enemy vessel [the British warship HMS Eagle] by Turtle took place in New York harbor in September 1776. Turtle functioned as anticipated, but the attack… did not succeed. Two subsequent attempts to attack British warships were thwarted by navigational issues and tides. Before Turtle could be re-deployed, it was sunk along with the sloop transporting it by enemy fire on 9 October 1776. Although recovered, Turtle saw no further service. Its eventual fate remains a mystery.
Although it did not achieve military success, Turtle was seen by men of the time as a revolutionary development. In 1785, George Washington wrote Thomas Jefferson: “I then thought, and still think, that it was an effort of genius.” The problem with Turtle, as the former head of the Naval Historical Center, Admiral Ernest M. Eller wrote, was Bushnell’s expectation that just one man could “carry out the combined duties of diving officer, navigator, torpedoman, and engineer, while at the same time fighting tides and currents and propelling the boat with his own muscles.”
While a submarine “practical” for warfare with range, power and reliability had to await the coming of the mechanical age, Turtle was an indispensable first step, which made future developments possible.
In short: The Turtle was a truly Revolutionary submarine, and it led to David Bushnell being credited as the Father of Submarine Warfare. But why did Ezra Lee’s attack fail? This excerpt from Connecticut History’s excellent article on the Turtle explains it, using Lee’s own testimony:
Later [in life], Lee described his unsuccessful attempt to fasten the mine [to the HMS Eagle]. “When I rowed under the stern of the ship, could see men and deck and hear them talk-then I shut all doors, sunk down, and came up under the bottom of the ship, up with the screw against the bottom but found that it would not enter.” Unable to affix the mine and with daylight upon the water, Lee decided to make for shore before the vessel was discovered by passing boats. But it was too late. Guard boats put off from shore in his direction and soldiers mounted the fort on Governor’s Island to catch sight of the strange craft.
Lee writes that he “let loose the magazine [mine] in hopes, that if they should take me, they should likewise pick up the magazine, and then we should all be blown up together…” Ezra Lee did not lack courage, only experience in a craft no one on earth had ever before piloted in action. The mine did explode, frightening off the pursuing guard boat; Lee escaped with his life and with Bushnell’s machine.
So how accurate is TURN’s use of the Turtle in the Season 2 episode “Providence”? TURN scores much higher than usual regarding historical accuracy when it comes to their use of the Turtle! In case there was any doubt, none of the Turtle’s missions involved Caleb Brewster or any part of the Culper Spy Ring whatsoever; if you look at our TURN Historical Timeline, you’ll find that the real-life Turtle set sail two full years before the Culper Spy Ring was even formed.
That said, the show’s incorporation of the submarine into its alternate history storyline was certainly entertaining, and it very closely paralleled pilot Ezra Lee’s original mission of 1776. (The notable exception being Caleb’s success in blowing up an enemy ship with an underwater mine where Lee had failed!) The Turtle used in the show is a dead ringer for the meticulously-researched 21st century museum replicas, and Caleb even mentions the use of Foxfire as a light source! Regarding Ben Tallmadge and “Davey” Bushnell meeting at Yale: Tallmadge (Class of 1773) was two years ahead of Bushnell (Class of 1775) at Yale, so their educations did overlap by two years. However, since Bushnell matriculated at the unusually ripe old age of 30 and was therefore twice as old as the average Yale student, he may have had less social interaction with his fellow undergraduates than a typical student — so Tallmadge’s line about how he “didn’t know much” about him makes a lot of historical sense, too.
All the Turtles of the World
If you want to see (or climb into) a Turtle yourself, Connecticut is a good place to start. The State of Connecticut is pretty darn proud of its submarine heritage: During the Revolutionary War, CT native David Bushnell’s efforts found widespread support among prominent Connecticut patriots like Silas Deane and Governor Jonathan Trumbull, who actually ended up convincing George Washington to support the Turtle venture. Modern-day Groton, Connecticut, the “Submarine Capital of the World,” is home to an active US sub base, the nuclear submarine manufacturer Electric Boat, and a museum that houses the first nuclear submarine in the world, the USS Nautilus.
So it’s little surprise that Connecticut is home to at least three full-size Turtle replicas. Two of them reside at the Connecticut River Museum in Essex; one is a cutaway model you can climb in yourself, and the other is a fully-functional reproduction that embarked on its maiden voyage in November of 2007. Another cutaway model, complete with a mannequin of Ezra Lee inside, can be found at the same Submarine Force Museum in Groton, CT that is home to the USS Nautilus.
The Royal Navy Museum in Gosport, England also has a Turtle replica, although their model is likely an older one, given that it’s much more spherical than the more recent, 21st century American replicas.
Finally, I thought I’d end this post by sharing some modern-day Turtle-related News of the Weird. It turns out that not every replica of the Turtle belongs to a museum; at least one of them belongs to an eccentric artist in New York City who found himself in trouble with the authorities on more than one occasion. Observe:
No, this isn’t a parody account of a Loyalist newspaper from 1776 — this incident happened in 2007! Philip “Duke” Riley, an artist with a history of embarking on legally-questionable stunts, built a working Turtle replica out of cheap plywood with the goal of stealthily approaching a British ship in New York Harbor (in this case, the Queen Mary II) in order to take pictures for an upcoming art installation. Riley and his two co-conspirators were promptly arrested after the New York Police and Coast Guard swooped in to intercept the little wooden sub. The New York Times (and plenty of other NY-area papers) published a full account of the bizarre and comical event that, like the Turtle itself, is almost too incredible to believe. The usually-stoic NYT wrote that Riley’s sub “resembled something out of Jules Verne by way of Huck Finn, manned by cast members from “Jackass.””
If you were feeling charitable, I suppose you could argue Mr. Riley was helping to keep the fascinating legacy of the Turtle alive in his own… unique way. On his own website, which has plenty of additional pictures and video of the submarine launch, he claims his voyage helped expose persistent security lapses surrounding New York Harbor. Whatever your opinion of Riley’s “marine mischief,” at least we got to see a replica of a Revolutionary War submarine on the cover of the New York Post, complete with a snarky headline!
There’s so much for to be said about the history of the Turtle and the brilliant innovation that went into it, but alas, there is only so much we can stuff into one blog post! For more Turtle articles, primary sources, sketches, and other resources, see the Further Reading section below.

Collection of photos, diagrams, and sketches of the Turtle from a variety of sources.
A few weeks ago, I took a leisurely day trip to New York City with friends who had recently moved to the area. As I emerged from Grand Central Station, blinking in the bright sunlight after a good ninety minutes on the train, I almost thought I was hallucinating when the first thing I saw in front of me was a little picture of British soldiers in cocked hats sitting atop a yellow taxi. Thankfully, I had my camera out when this bus drove by moments later:
(I think the “Pledge Defiance” banner running along the top of the bus is an especially nice touch.)
My own experience was corroborated by two other perceptive Connecticut
agents friends of mine who had visited New York City in recent weeks. Nisreen spied another TURN bus, while Steve surreptitiously snapped a photo of an ad in a subway station.
Over the course of the day, I saw many more ads for TURN on buses and taxis throughout the city — in fact, the only other TV show that seemed to be promoted more heavily than TURN in print advertising was HBO’s Game of Thrones. Pretty fitting, since one of the show’s primary settings will likely be 18th century New York City, although you’d never know it from the ad itself.
If anyone else has spotted ads for TURN in their corner of the country, please share! So far, this particular ad campaign guarantees that TURN is on the radar of literally millions of people in the New York City metro area. Whether they’ll actually tune in for the April 6th premiere, however, remains to be seen.
