A trip to the lab: It was a thrill to briefly hold a conserved Enfield rifle and see one going into a preservation tank at Georgia state park. These weapons and 18 others were found in a blockade runner wreck. The goal is to put them on exhibit

There are fun days and then there are really, really fun days. Today was one of the latter.

I began my adventure by hopping into my old SUV for the leafy drive to Panola Mountain State Park near Stockbridge, Ga., below Atlanta. I was excited about finally meeting Josh Headlee, curator and historic preservation specialist with the Georgia Department of Natural Resources.

We have stayed in touch by phone or email for nearly 13 years about a conservation project he calls “a labor of love.”

Of course, I was equally excited about seeing the fruits of that project: Two Civil War Enfield rifles that were part of a crate of 20 lost when a Confederate blockade runner ran aground in Charleston, S.C., in 1863. South Carolina divers brought them up in the late 1980s; the artifacts eventually came to Georgia, which had larger facilities to handle them.

The conservation of the rifles last year reached a significant milestone, with the first walnut stock emerging from treatment and appearing to be doing well outside a wet environment.

I had a chance to briefly hold the rifle stock this morning before we drove over to a laboratory housed in a former golf course building. Adrian Fox, interpretive ranger at Sweetwater Creek State Park, and I had the honor of watching Headlee dip the second gun into a preservation for a two-month bath (Picket video, above).

The British-made weapons have been displayed for nearly 15 years in a 300-gallon aquarium at Sweetwater Creek State Park in Douglas County as corrosive salts are removed. Headlee, who cleans the tank a couple times a year, chose guns 9 and 10 as the first to be treated with a preservative.

Visitors to Sweetwater Creek – about 50 miles from Panola Mountain - are a bit puzzled when they first see the aquarium, said Fox and Headlee. After all, shouldn’t it contain fish or turtles? And the mass of guns, a crate and lead lining appear to be a jumble.

Park employees tell them the gun cache is inherently interesting.

“It gives folks a rare glimpse to see historic preservation in action,” Fox told me. Staffers often hold a replica rifle near the tank to help them visualize what’s inside.

Conservation is a long process, so there is no timetable on when the weapons  – which have been in salt or freshwater for 163 years -- are completed. And there has been no decision on where they might be exhibited, finally free of a watery environment.

Headlee says Fort McAllister State Park below Savannah might be appropriate, given the Rebel blockade runner CSS Nashville was sunk there by the Union ironclad USS Montauk.

Blockade runner wreck served up a treasure

The Pattern 1853 Enfields were carried by the blockade runner CSS Stono and were bound for Charleston, S.C., in 1863. The rifles, stored in a wooden crate, were placed in an alternating butt-to-muzzle pattern, and blocks were used to prevent the weapons from shifting. 

The Stono, laden with precious arms, munitions and goods from Europe, ran aground on a submerged sandbar off Fort Moultrie in Charleston Harbor while trying to evade Federal ships.

The crate likely took a hard fall, breaking a few rifles, according to Headlee. (Picket video above and photo, right, of conserved rifle, piece of crate)

Saltwater destroyed most of the iron components, including barrels, locks and bayonets. The trigger guards, butt plates and nose caps at the end of the barrels are made of brass and are still intact.

Interestingly, the nose cap is the only metal piece still attached to the wooden stock of the treated rifle. It appears to be riveted in place and conservators don't want to risk breaking the fragile stock to remove it for treatment. 

Officials did not initially know how many of the highly prized Pattern 1853 rifles were inside, their position or condition. 

Each weapon originally weighed about 9 pounds and was approximately 53 inches long. The bore is .577-caliber. 

The treated rifle I hoisted weighed probably half of that, because much of the metal (iron) had corroded away.

The brass pieces survived. The iron, not so much

The craftsmanship involved in the manufacture of the guns was very good, Headlee previously said. “Enfield was top quality.” It was the second-most widely used infantry weapon in the Civil War after the Springfield.

The 1851 and 1853 Enfields, made for the British army, were an important technological advance from smoothbore to rifled muskets, increasing the accuracy and distance.

At least one of the weapons bears the mark, “T. Turner,” believed to be a Confederate inspector of the rifle. His name was on a stamped cartouche in the wood.

A tin and lead lining that sealed the cargo from salt air and ensured the rifles were not tampered with is in bad condition. Officials are not sure how much of that can be salvaged for display. The wooden lid to the box did survive and is resting in a freshwater tank with other components.

There is a silver lining to all of this: Components made of brass withstood the onslaught of corrosive saltwater.

Iron or steel screws holding the butt plates in place deteriorated over the years and the plates just slid off, said Headlee.

Conservators years ago found in the crate a bullet mold, tools and tampions -- cork and brass plugs inserted into the muzzle to ward off moisture. The team counted 20 tampions “in various states” of condition. 

Tampions are used on cannons and rifles to keep debris from falling into their barrels. (Picket photo, left, of tampion and other items at Panola Mountain.)

Headlee reached out to Enfield experts in England and elsewhere about the half dozen remnants of iron bayonets found stacked together. They told him bayonets normally would be shipped in a separate box.

“Why bayonets were in this crate I have no idea,” Headlee told the Picket last year. “They are all but gone. The fact we have this much is amazing.” The pieces are about an inch and a half long.

The Enfield fired a Minie ball. No ammunition was found in the crate.

A jug of preservative and a case of nerves

Headlee in 2022 selected two rifles  to be treated with a solution made by Preservation Solutions. Conservators previously used SP-11 to treat an intact coffin found in 2013 on the edge of the marsh at Fort McAllister, a Confederate river outpost below Savannah. Results on the coffin led to use on the Enfields.

Before the chemical treatment, the rifles are kept in water, which protects their cellular structure.

The treatment takes about two months and the rifle is turned once.

Without immersion in a preserver, pieces of wood will shrink, warp and crack.

“They could literally just fall apart,” Headlee previously told the Picket.

SP-11 is designed to displace water in the wood with preservatives that help to solidify the wood so it can be permanently exposed to the air. (At left, butt plate and other components, Picket photo)

The curator has been watching the preserved rifle to see whether there is leaching, cracking or splitting of the wood. 

He has seen no problems; a white film appeared on some of the stock as it emerged from the tank, but it was successfully cleaned off, he added.

“So far, it looks good,” Headlee said during my visit.

If the second rifle does as well as the first, another two rifles will be selected for the preservation treatment, perhaps this summer. In the meantime, he will travel back to Sweetwater Creek in the coming weeks to clean the tank and inspect and care for its contents. Fox, the interpretive ranger, said the staff there is very interested in the progress of the work.

The curator concedes he was nervous when the first gun emerged from its bath, and he will probably want to babysit the second a bit, as well.

As for me, it was exciting to see the Enfield components up close, especially the wooden block (Picket video above) that held the rifles in place when they were crated more than 160 years ago. I just imagined a craftsman cutting the grooves in which the barrels rested.

Oh, what a day.

Conservation in Georgia of 20 Enfield rifles has reached a significant milestone, with the first walnut stock emerging from treatment and appearing to be doing well outside a wet environment.

“I was thinking about it; this is the longest this rifle has been out of water in over 160 years,” said Josh Headlee, curator and historic preservation specialist with the state’s Department of Natural Resources.

“I want to give it a little time to monitor it closely and make sure nothing bad is going to happen to it. However, I think it’s going to work. The rifle seems pretty stable,” he said.

The British-made weapons – which went down with a Confederate blockade runner in Charleston Harbor -- have been displayed for nearly 15 years in a 300-gallon aquarium at Sweetwater Creek State Park in Douglas County as corrosive salts are removed.

Saltwater destroyed most of the iron components, including barrels, locks and bayonets. The trigger guards, butt plates and nose caps at the end of the barrels are made of brass and are still intact.

The state’s aim is to eventually exhibit the wooden remnants of the rifles.

Lab picked two rifles for initial treatment

Headlee in 2022 selected two rifles (left, Georgia DNR) to be treated with a solution made by Preservation Solutions. Conservators previously used SP-11 to treat an intact coffin found in 2013 on the edge of the marsh at Fort McAllister, a Confederate river outpost below Savannah.

Before chemical treatment, the rifles are kept in water, which protects their cellular structure. 

Without immersion in a preserver, pieces of wood will shrink, warp and crack. “They could literally just fall apart,” Headlee previously told the Picket. (Treated rifle above, Georgia DNR. View shows were the lock and hammer would have been.)

SP-11 is designed to displace water in the wood with preservatives that help to solidify the wood so it can be permanently exposed to the air.

The curator said he is watching the preserved rifle to see if there is leaching, cracking or splitting of the wood as it continues to dry.

If this weapon remains stable, Headlee said, the second Enfield will undergo the treatment. “We’re slowly picking the hard crusty layer off of it before we put it in the wood preserver,” he added. (Left side of the rifle, above)

The items are being treated at a facility at Panola Mountain State Park east of Atlanta.

Divers pulled up prized weapons decades ago

The Pattern 1853 Enfields were carried by the blockade runner CSS Stono and were bound for Charleston, S.C., in 1863. The rifles, stored in a wooden crate, were placed in an alternating butt to muzzle pattern, and blocks were used to prevent the weapons from shifting.

The Stono, laden with precious arms, munitions and goods from Europe, in 1863 ran aground on a submerged sandbar off Fort Moultrie in Charleston Harbor while trying to evade Federal ships.

An archaeological diver pulled up the box carrying the 20 rifles in the late 1980s. One end was damaged, apparently when the ship sank. Some of the Enfields were damaged.

Officials did not initially know how many of the highly prized Pattern 1853 rifles were inside, their position or condition. 

Each weapon originally weighed about 9 pounds and was approximately 53 inches long. The bore is .577-caliber. (At right, treated gun, Georgia DNR. It shows were the trigger guard and assembly would have been.)

The craftsmanship involved in the manufacture of the guns was very good, Headlee previously said. “Enfield was top quality.”

The Enfield was the second-most widely used infantry weapon in the Civil War after the Springfield.

The 1851 and 1853 Enfields, made for the British army, were an important technological advance from smoothbore to rifled muskets, increasing the accuracy and distance.

At least one of the weapons bears the mark, “T. Turner,” a reference to well-known English gunmaker Thomas Turner, who turned out quality weapons in the mid-19^th century.

Barrel plugs called tampions remarkably survived

 A tin and lead lining that sealed the cargo from salt air and ensured the rifles were not tampered with is in bad condition.

But there is a silver lining to all of this: Components made of brass withstood the onslaught of corrosive saltwater. Conservators are still trying to determine how to treat them.

Iron or steel screws holding the butt plates in place deteriorated over the years and the plates just slid off, said Headlee.

Conservators years ago found in the crate a bullet mold, tools and tampions -- cork and brass plugs inserted into the muzzle to ward off moisture.

The team counted 20 tampions (above, Georgia DNR) “in various states” of condition. Tampions are used on cannons and rifles to keep debris from falling into their barrels.

Headlee finds it remarkable much of the cork used for the Enfield tampions remains.

“They were just found in a grouping. We feel like they were in a box or bag in the crate.”

A closer look at chains and bayonet remnants

The Enfields featured a nipple protector, which kept the hammer away from the firing mechanism when not in use. A chain was attached to a plug placed over the weapon’s nipple.

Headlee last year sent me a photo of one chain from the Stono guns (above, Georgia DNR). “Some of them are still on the rifles.”

He reached out to Enfield experts in England and elsewhere about the half dozen remnants of iron bayonets found stacked together. They told him bayonets normally would be shipped in a separate box.

“Why bayonets (remnant below, Georgia DNR) were in this crate I have no idea,” Headlee said. “They are all but gone. The fact we have this much is amazing.” The pieces are about an inch and a half long.

The Enfield fired a Minie ball. No ammunition was found in the crate.

Eventually, if all goes as hoped, the 20 rifles will go on display somewhere in the state.

“Even up to the end of the (Civil War), the Enfield rifle was kind of the M16 rifle of the day,” said Headlee. “It had been used for years and years. Bang for the buck, it was as good as any standard weapon.”

Springfield and Enfield rifles were neck and neck in effectiveness, he added. “They were like a Ford and a Chevy.”

Interestingly, the  nose cap is the only metal piece still attached to the wooden stock of the treated rifle. It appears to be riveted in place and conservators don't want to risk breaking the fragile stock to remove it for treatment. 

Battle of Hampton Roads anniversary: They flocked to a Va. museum to look at USS Monitor artifacts and get a good view of its turret, which is normally submerged

Hundreds of those attending a Battle of Hampton Roads anniversary event at a Virginia museum got a rare glimpse Saturday at the USS Monitor’s battle-marked turret out in the open, rather than awash in conservation solution.

Conservators at The Mariners’ Museum and Park in Newport News in January accessed the turret for the first time in more than five years, following draining of the 90,000-gallon tank that surrounds the remarkable ironclad artifact.

Since then, a treatment solution has been drained and filled weekly as conservators perform maintenance in its interior. Dents from Monitor's 1862 duel with the CSS Virginia are visible today.

Will Hoffman, director of conservation, told the Picket the 20-year conservation process is working.

"What we have seen is the further loosening of corrosion since the last time we were in the tank. This corroborates what our electrochemical monitoring system has shown," he said.

Sabrina Jones, senior director of advancement at the museum, told the Picket in a Monday email an estimated 70 percent of Saturday's 1,000 visitors attended an open house at the “wet lab” that houses the upside-down turret and other Monitor items still undergoing conservation.

Following this weekend, a new treatment solution will be incorporated into the turret tank by the end of the week, Jones said.

"Conservators will not enter the tank again until maintenance is required (likely years) or until we are ready to 'flip' the turret. We do not have a timeline on the flipping as it needs several partners to 'engineer' it and a campaign to fund the materials and work," said Jones.

The tank was drained to allow for the assessment of the desalination process (removing harmful ocean salts), routine maintenance and the removal of nut guards from underneath the turret. The nut guards are the remains of thin armor plating used in part of the turret.

March 8-9 was the anniversary of the clash between the ironclad and Virginia.

“That turret is the first turret that fought in combat in world history,” Hoffman told TV station WAVY ahead of the weekend. “Every turret on a ship, you know, from gun battleships all the way through now with autonomous Lidar you see on modern ships, all that comes from the turret that’s sitting in that tank behind me.”

The turret was raised off Cape Hatteras, N.C., by U.S. Navy and other divers in 2002 and brought to Newport News. The Mariners’ Museum and Park displays hundreds of Monitor items recovered since its discovery in 1973.

Many artifacts, including two Dahlgren guns, gun carriages and personal effects from sailors were recovered from inside the turret. The finds there included the remains of two men who were unable to escape when USS Monitor sank during a storm on Dec. 31, 1862, as it was being towed south in the Atlantic Ocean.

Saturday’s events included lectures, 3D-printed artifacts, a STEM design program and tours of the museum galleries. It was cosponsored by NOAA's Monitor National Marine Sanctuary. This year's focus was about maritime careers, such as engineering and underwater archaeology.

"This weekend was an absolute home run as the galleries were buzzing all day with new and returning folks," said Jones.

USS Monitor Center director emeritus John Quarstein, who was among the speakers, told the Picket he has been inside the turret numerous times over the years.

“My amazement is based on several experiences.... when I thought about the shot damage, when I think about the men serving in the turret and what they experienced, when I realize how the turret revolutionized naval warfare, etc. I also think about the many design flaws found when looking at the turret and then think about all of the graft, greed and grift involved in ironclad construction during the War of the Rebellion,” he wrote in an email.

Quarstein has a new book, “From Ironclads to Admiral: John Lorimer Worden and Naval Leadership,” coming out next month. Worden skippered the USS Monitor during the battle and later served on the USS Montauk.   

Retired atmospheric physicist and author Charles McLandress presented a lecture about William F. Keeler, his great-great grandfather. Keeler’s numerous letters home are the basis of a book by McLandress, "Ink, Dirt and Powder Smoke: The Civil War Letters of William F. Keeler, Paymaster on the USS Monitor."

“The main points of my talk were to highlight the importance and beauty of Keeler's Civil War letters and to tell the life story of this complex and fascinating individual (Forty-Niner, dry goods merchant, watch maker, iron founder, inventory, orange grower, newspaper correspondent and more),” McLandress told the Picket. “I interweaved the story of the Monitor with Keeler's impressions of events and people, with focus on the Monitor.”

These tools helped keep submarine Hunley running -- whether on the surface or underwater. The gizmos are now on exhibit at conservation lab near Charleston

Conserved glass bottle, wrench and hammer carried by sub crew (Friends of the Hunley)

In-depth research and tinkering went into the design and construction of the stealthy submarine H.L. Hunley. While there were predecessors, the Confederate vessel was the first to be an effective weapon, sinking a Union ship off Charleston Harbor.

“We think it was very watertight. The construction was very sound, according to the riveting,” said Nick DeLong, among the Clemson University archaeologists conserving the Hunley at a lab in North Charleston, S.C.The rivets were inverted, creating a smooth exterior and reducing drag in the water.

“They knew a lot more about hydrodynamics than people thought,” DeLong told the Picket on Thursday as the Friends of the Hunley announced “Tools & Tides,” a new exhibit at the Warren Lasch Conservation Center.

The submarine had a rather complex system of drawing, pumping and discharging water, so the moving parts required regular maintenance. The Hunley was a “work in progress” that required the crew to keep it seaworthy with common tools. Adding to the challenge was a tiny environment that featured limited lighting and likely condensation from water, sweat and breathing.

The small exhibit, timed to the anniversary of the Feb. 17, 1864, sinking of the USS Housatonic, features tools that would be useful for quick repairs. The display (left) includes bolts, a wrench, chisel and hammer -- items you would find in a Home Depot, for example, but took years of conservation to be made ready for their debut.

The exhibit opens to the public this weekend.

“It was a very basic tool set to help (with) anything on the fly,” said DeLong. “While the submarine was revolutionary, they had to use what they knew to solve problems they could not foresee.”

The eight-man crew perished after the Hunley went down after jamming a torpedo into the Housatonic’s wooden hull. To this day, historians and others disagree on what caused the loss of the Hunley shortly after it became the first submarine to sink an enemy vessel.

It’s tempting to engage in conjecture on how the artifacts could have been used to save the ship. For example, if there was a problem with the ballast tank, perhaps the wrench or a T-shaped tool would have been helpful in making a repair, allowing the Hunley to rise to the surface. But we just don’t know what failed.

Here’s a look at the recently conserved items in the new exhibit, with all photos and most of the captions provided by the Friends of the Hunley. Several tools were discovered beneath Capt. George Dixon’s bench. DeLong said the artifacts likely did not shift much when the Hunley went to the bottom. This is the first time they have been put on exhibit.

Glass bottle

The 12-sided glass apothecary bottle was found on the crew bench still holding liquid from 1864 (The hand-cranked submarine was recovered in 2000 and has proved to be a time capsule holding precious artifacts).

The contents of the bottle remained a mystery until testing revealed it was mercury, which was most likely used for the submarine’s depth gauge. DeLong says the remaining fluid in the container matches the amount of mercury needed to operate the gauge.

T-shaped tool

The artifact was found between the pump mechanism and the frame ring, suggesting it was used to adjust or remove portions of the forward ballast pump. The Hunley had a forward and aft pump, with the crew department in between, DeLong told the Picket.

“They (the pumps) were quite effective. They were connected through piping so if one failed the other would pump water.” The crew opened a valve that would allow water in, making the Hunley descend. The pumps pushed water out so that it could rise to the surface.

Chisel

This wrought-iron tool was uncovered next to the forward bulkhead. It was stuck to the hull and bilge pump pipe due to heavy concretion. It has a flat-blade edge and would have been used for general utilitarian tasks.

Bolts/wedges

The tools served as flat-head wedges, according to DeLong. They were used to hold some of the submarine’s frame rings.

The bolts, with an attached nut, were found beneath the forward pump outflow pipe under the captain seat and could have been integral components in the ballast and pump system's operation.

They were treated using a sub-critical chamber, a cutting-edge conservation technique developed by the Hunley scientific team, officials said in a press release. 

Ball-peen hammer

Made of different materials, the ball-peen hammer required different conservation methods. For example, the treatment used for the iron can be detrimental for the wood handle. The Clemson team removed the head of the hammer and placed it in sodium hydroxide. The handle was immersed in polyethylene glycol.

Wrench

This large adjustable monkey wrench underwent desalination in sodium hydroxide and then was rinsed in deionized water and placed in the lab oven to quickly dry. Next, it was cleaned with air abrasion and a special coating was applied to protect the metal from corrosion.

They plan to dive deeper into use of the tools

The Clemson archaeologists intend to do a deeper analysis of the use of these tools and their interaction. The T-shaped item may have been a key, but the project does not know how it was used, said DeLong.

“We want to look at the submarine as a functioning artifact,” he said. Among the topics to be studied was the Hunley’s air intake system

DeLong is among those completing a volume on the crew members and their personal belongings.

The Hunley museum is open from 10 a.m.-5 p.m. on Saturdays and 10 a.m.-3 p.m. on Sundays. The Warren Lasch Conservation Center is at 1250 Supply St. in North Charleston. Tickets for tours can be purchased online here. The cost is $18 for adults and $10 for youth ages 6-12, plus a service charge

On Picket first: USS Monitor conservators drain turret tank for first time since 2019, will conduct visual checks and maintenance inside beginning Thursday

Conservators later this week will be able to access the turret of the USS Monitor for the first time in more than five years, following Monday’s draining of the 90,000-gallon tank that surrounds the remarkable artifact.

The Mariners’ Museum and Park in Newport News, Va., broadcast the four-hour draining – the first since 2019 -- on YouTube and took questions from those curious about the long conservation process.

For the next several weeks, the treatment solution will be drained and filled weekly, and conservators will have access to the turret interior for maintenance. They are expected to enter the turret Thursday.

"On the days the conservators are physically working in the turret tank, they will stop occasionally throughout the day to run the sprinklers in the tank, in order to keep the turret saturated and prevent drying," said Tina Gutshall, The Mariners' grants administrator. "The rest of the year, the tank stays filled."

One benefit will be for museum visitors to see the empty turret on March 8, the anniversary of the 1862 Battle of Hampton Roads between the Union ironclad Monitor and CSS Virginia.

Following that, a new treatment solution will be incorporated into the turret tank, The Mariners' said.

The tank was drained to allow for the assessment of the desalination process (removing harmful ocean salts), routine maintenance and the removal of nut guards from underneath the turret. The nut guards are the remains of thin armor plating used in part of the turret.

A live chat during the draining brought a host of questions, including the goal of conservation, other shipwrecks, the sophisticated design of the turret and more. One commenter said an ancestor was a carpenter who worked on USS Monitor’s interior wood components.

Will Hoffman, chief conservator, participated in part of the chat, saying he and his colleagues were excited about getting inside the turret during the next several weeks to assess the treatment and clean the electrolytic reduction system that removes salt.

The turret was raised off Cape Hatteras, N.C., by U.S. Navy and other divers in 2002 and brought to Newport News. It is positioned upside down.

The chat and YouTube presentation asked for donations and support for the long-term project.

The next step is to flip the turret and treat it with dry ice. The conservation of the turret could be complete within 10 years, but officials have no firm timetable.

Crews have worked inside the turret during previous drainings, but most were several years ago. The long-term aim is to put the turret on display at the museum with other Monitor artifacts.

“We are working closely with NOAA to encourage support from industry experts on the technical expertise and to raise the funds to make this next monumental step a reality,” Hoffman said in the chat.

A major point of study is whether it is best to treat the turret as is (a large ring), or to take apart the 198 wrought iron plates, which are in bolted layers of eight, to get at them separately. "We do not plan to take the armor ring apart, but aim to disassemble the roof assembly once the turret has been rotated," conservators said in an email to the Picket.

I asked Jeff Johnston, who was a historian and program specialist with NOAA’s Monitor National Marine Sanctuary, about the significance of Monday’s tank draining.

“It allows the conservators a chance to inspect how the conservation is progressing, replace any anodes that need it, and/or reposition anodes for better treatment where necessary,” he said. “They can inspect the turret and clean up any generated sludge. It's also a great opportunity for museum visitors to get a good look at the turret while the maintenance is happening.”

Additionally, Johnston said, conservators have the option of dry ice blasting to help the electrolysis better reach the surface metals and reduce rust. The museum said this week that approach continues to be the plan.

"Full dry-ice cleaning will follow the turret rotation, which is still in the planning phase," conservators said.

Many artifacts, including the two Dahlgren guns, gun carriages and personal effects from sailors were recovered from inside the turret. The finds there included the remains of two men who were unable to escape when USS Monitor sank during a storm on Dec. 31, 1862, while it was being towed.

One commenter wondered how the ironclad’s crew coped with the concussive forces generated when the Virginia’s shells struck the turret.

“​​It is incredible to imagine what it would have been like inside the turret during the Battle of Hampton Roads,” the park replied. “It was hot, the ships were exchanging fire and the turret was spinning continuously.”

USS Monitor Center director emeritus John Quarstein told the Picket several sailors and officers were concussed during the battle, including chief engineer Alban Stimers. “When the first shots from the CSS Virginia struck the turret's side, everyone in the turret then knew that nothing could harm them.”

Quarstein (left), who routinely gives lectures on USS Monitor and other Civil War vessels, says the ironclad was truly a revolutionary warship.

“So many sections of the little ship that saved the nation, especially the turret, reinforce the fact that the Civil War is the first industrial war which changed America forever.”

On March 6, 1862, the new Union ironclad – its radical design dubbed “Ericsson’s folly” by its doubters -- steamed down New York City’s East River for the short journey to Virginia. There were doubts about whether the Monitor could withstand the seas and intense enemy firepower; it fired only two cannons from the revolving turret.

But the small ship quickly challenged the heavily armored CSS Virginia upon arrival and ended the latter’s rampage against Federal ships. The stalemate foreshadowed the end of wooden warships.
