Civil War Submarine

Confederate Efforts to Build an Effective Civil War Submarine

Drawing designs and constructing prototypes of 1860’s submarines was one thing, but keeping the crew alive was something quite different. The latter was more difficult.

The impetus for the Confederate Navy to build an effective Civil War submarine was to aid in Union blockade running. Part of the Union plan to win the American Civil War was to choke off all southern ports. Union blockades were effective but not foolproof. The Confederate Navy did have a degree of success in running the blockades.

The Confederate side built their first submarine model in New Orleans in 1861. It was named the “Pioneer” made of heavy iron plates at a length of nineteen feet. A crude snorkel was used to supply oxygen to the crew. The ownership of this Civil War submarine wasn’t the Confederacy directly, but rather three southern Confederate supporters. Two were marine engineers named Baxter Watson and James R. McClintock. The third was a southern businessman by the name of Robert Barrow. Barrow was helped by his wealthy brother-in-law, Horace Lawson Hunley. Hunley, originally from Tennessee, had deep pockets.

The submarine Pioneer was tested in the waters of Lake Pontchartrain. The vessel showed promise during the first test having sunk a barge with a torpedo. The second test didn’t fare quite as well in as much as the crew of four were killed. Not long after that, New Orleans was taken by the Union’s Admiral David Farragut in April 1862.

Another Attempt from Mobile Alabama

When Admiral Farragut took New Orleans, the builders of the Civil War submarine Pioneer fled east to Mobile Alabama with the plans. There, they teamed up with a British machinist and set out to build another southern submarine. The group did build another model but it soon sunk during tests without any loss of life.

The groups next creation would eventually become the submarine CSS Hunley. The basis of the CSS Hunley was an old twenty-five foot long boiler.

How the CSS Hunley Operated

The Civil War submarine CSS Hunley obviously operated quite crudely compared to the early German U-Boats of World War One. By the same token, it was engineered amazingly well for the year 1862 considering that covered wagons still crossed the Overland Trail.

The power source that turned the vessels propeller consisted of the crew. A special rod bent to make handles was connected to the propeller which the crew turned by hand as shown on the CSS Hunley diagram in this article. This alone allowed the boat to move. The top of the boat’s hull had two hatches that were raised about eight inches above the top hull surface and which was fitted with glass and waterproofed by rubber edges. This was the one way the crew could observe where they were and what was on the water surface. The weapon was a torpedo that was hauled by the sub by a 200 foot long rope. When the vessel submerged the captain would light a candle and water would fill the tanks until the submarine submerged to about three inches under water. The depth was accomplished by the captain depressing a lever that worked the diving fins.

Off to Charleston

The CSS Hunley appeared to be a design and operational  success and by late summer of 1862 the Civil War submarine was shipped off to Charleston South Carolina by rail. Her task in Charleston would be to help penetrate the Union sea blockade.

Unfortunately for the Confederacy, submarine troubles were not behind them. One time when the Hunley was in Charleston harbor a passing steamer’s wake flooded the open hatch of the Hunley and sent her down. A Lieutenant who was just about to close the hatch ended up escaping and was the only survivor. This demonstrated just how dangerous this type of duty was. After the sub was raised, another series of trials were undertaken and additional volunteer crews were lost including the Lieutenant who had previously escaped the first sinking. Even more tests were performed with volunteers and after some further close calls the CSS Hunley was amazingly declared ready for duty.

The CSS Hunley vs the Union Sea Blockade

History records show that the Union Navy was not totally unaware that the Confederacy was working on a secret new marine weapon. Nevertheless, the Union ship Housatonic surprisingly ended up being the victim of the  CSS Hunley. Ship lookouts had spotted a strange submerged object approaching their vessel but couldn’t quite figure out what it was. At first it was thought to possibly be a porpoise. Shots were fired at this submerged object as it came even closer but the ships heavier guns couldn’t shoot at that low of an angle. Rifles and shotguns were shot at the object to no avail.

Even though the Housatonic began drifting, the Hunley made contact with the hull of the Housatonic and an explosion occurred. Her crew began evacuating the sinking vessel and were picked up by another Union ship. Eventually, the Housatonic sank in about twenty-eight feet of water. Five crew members were lost and the Union investigation afterwards determined that some type of torpedo had destroyed her.

Where Was the CSS Hunley?

The Hunley disappeared. When the Confederates learned about the sinking of the Housatonic about a year later, they figured that the Hunley must have been dragged down to the bottom by her victim and her entire crew lost. Years later however some witnesses would say that the submarine was a hundred feet away from the Housatonic when the explosion occurred.

The location of the attack was well known and the wreck of the sloop Housatonic was eventually moved. At the time, divers did indeed notice the Confederate submarine during this removal but made no effort to salvage the vessel. Again, when the Housatonic had been hit, the existence of the Hunley wasn’t a known fact. The only thing that was determined was that the Houstatonic was hit with some type of torpedo or other explosive device.

The location of the CSS Hunley was unknown for over a century after the explosion. The Hunley was eventually discovered by the National Underwater Marine Agency archeologists Ralph Wilbanks, Wes Hall and Harry Pecorelli on May 3rd 1995. One of the Hunley’s conning towers was discovered under a few feet of sediment off Sullivans Island in Charleston Bay. The silt which covered the Hunley’s hull actually served to protect it from the salt water that is known to erode most sunken ships. The vessel was pretty much intact and in good condition aside from the front viewport.

Viewing the CSS Hunley Today

The discovery of the Confederate submarine CSS Hunley is obviously one of the more historic finds of the twentieth century. The public is invited to see the Hunley themselves. The old CSS Hunley can be seen on weekends only at the Warren Lasch Conservation Center, located at 1250 Supply Street (on the old Charleston Navy Base), North Charleston, South Carolina.

Confederate Navy

The American Civil War battles were waged all over the south, in the far west in the present state of Arizona and in the north at Gettysburg. One of the somewhat under publicized actions undertaken by the Confederate Navy were hostile events in the Atlantic as far north as Nova Scotia. Not only did significant action occur in the North Atlantic but damage to Union shipping was widespread. The navy in the Civil War was very active in the North Atlantic.

The CSS Tallahassee

This story’s focus is on the Confederate Navy’s ironclad coal powered steamer CSS Tallahassee and the nineteen days of raids during 1864. The Confederates named the ship after the Florida state capital. Interestingly enough, the CSS Tallahassee was able to obtain coal at Halifax. Neutrality laws applied to Nova Scotia but part of those laws required that a Civil War ship could only remain there 24 hours.The Tallahassee was originally named the Atalanta and had bee built on the Thames River in England. She was a fast vessel and very stable. With her twin screws, the Talllahassee was said to be able to cross the English Channel in 77 minutes. After the ship successfully ran the Union blockade in Wilmington several times, the Confederacy purchase her in 1864.

The CSS Tallahassee was successful in running the Union blockade at Wilmington North Carolina on August 6th and steamed northward. The Confederate steamer was described as about one thousand tons, painted a light lead color, no bowsprit, with two smoke-stacks and a red bottom. The Commander of the CSS Tallahassee was John Taylor Wood. Wood was a relative of Jefferson Davis and a grandson of President Zachary Taylor.

The CSS Tallahassee at War

After running the Union blockade on August 6th 1864, the CSS Tallahassee under the command John Taylor Wood went on a nineteen day spree of raids along the North Atlantic seaboard. The Tallahassee was responsible for the destruction of twenty-six ships. This Confederate Navy vessel had great success finding ways to steam through the blockades.

These raids on shipping were not lost on the Union Navy. In fact, the CSS Tallahassee had two Union gunboats on her tail as she sailed northward toward Halifax Nova Scotia. When the Tallahassee entered Halifax Harbor, Wood believed that the Union war ships anchored in the sea lane just outside the port. Commander Wood was well aware that he could be in a tight situation. While in port, the Confederate vessel loaded enough coal to make it to the nearest Confederate port and did repair work to her mast. The Tallahassee skipper met with luck. After spending some thirty-six hours at Halifax because of the mast repair, Commander Wood hired at local harbor pilot to guide him past the waiting federal vessels. This, the pilot did by using another more shallow channel generally used by fishing boats. The CSS Tallahassee reached the open sea and made her way back to Wilmington North Carolina.

As it turned out, there were no federal war ships waiting to intercept the Tallahassee. The first federal vessel that did arrive on the scene at the harbor entrance was the USS Pontoosuc which got there a few hours after the Tallahassee departed.

The Ship that Wouldn’t be Caught

Not only did the CSS Talahassee have a successful raiding run in the northeast in August of 1864 and then return safely to Wilmington from Halifax, but this well commanded Confederate Navy vessel continued to be very active in the Confederate war effort. The vessel took on a new name, the Olustee, and was put in command of Lt. W.H. Wood.

Again, the Olustee was successful in running the Union blockades. During the last part of October 1864 she ran a blockade and destroyed six ships off Cape Delaware. This time she did suffered damage while exchanging gunfire with federal war ships, nevertheless the Olustee did make it safely back to Wilmington.

A New Name and the Final Confederate Voyage

For a third time, the vessel received a new name by it’s Confederate owners. When the Olustee arrived back at Wilmington after the Cape Delaware action, the Confederacy changed her name to the Chameleon and removed her battery. Her new commander was Lt. J. Wilkinson. In late December 1846, the new Chameleon steamed toward Bermuda. Her mission was to obtain badly needed supplies and return to Wilmington.

The problem was that when the Chameleon tried to enter Wilmington or any other southern port she found it impossible. Commander Wilkinson decided to steam in the other direction and took the ship all the way across the Atlantic to Liverpool England.

The Chameleon arrived in Liverpool on April 9th 1864. The American Civil War was essentially over. The British seized the Chameleon and sold her to the merchant shipping fleet. Interestingly enough, the United States Government filed suit to have the vessel returned. After about one year, the Chameleon (aka Tallahassee and Olustee) was returned to the American consul in Liverpool and the U.S. government took ownership of the ship.

The CSS Tallahassee and History

There are several things that make the story of the CSS Tallahassee a significant American Civil War event. As mentioned at the beginning of this article, the danger to Union shipping in the Atlantic off New England by the Confederate Navy has not been an overly publicized element of Civil War history. This alone is significant. The fact that the then named CSS Tallahassee was able to raid for nineteen days and while being chased by federal war ships was able to find shelter in Halifax Harbor is another fascinating story. Add to this the fact she escaped from Halifax and safely steamed back to Wilmington is another unbelievable twist. In addition to all of the above, this same vessel under other names and other commands was able to continue running blockades and sink more Union vessels later the very same year.

The only real end to the story of the CSS Tallahassee was when she sailed to England in April of 1865 and effectively surrendered to the British government. In many ways, this vessel ended her wartime service to the Confederacy under her own terms, not by fire from a Union war ship.
