Step back in time aboard the restored USS Cairo, a Civil War ironclad wonder

James Eads’ Cairo and Edwin Bearss’ Discovery

In 1861, self-taught engineer James Eads took on what seemed impossible – building seven ironclad warships in just 100 days.

He set up shipyards across four states, paid workers top wages, and ran round-the-clock shifts to meet his deadline. The USS Cairo, one of these revolutionary vessels, sank in 1862 and stayed lost for nearly a century.

Then in 1956, historian Edwin Bearss found it using only old maps and a pocket compass. The river mud had kept thousands of Civil War artifacts in perfect condition.

Today, you can walk the decks of this restored ironclad at Vicksburg National Military Park and see history frozen in time.

A Self-Taught Engineer Built 7 Ironclads in Just 100 Days

James Eads grabbed a huge chance in August 1861 when the Union gave him a contract worth $89,600 per gunboat. The catch?

He had to build seven ironclad warships in just 100 days. Eads took this on without any formal education or shipbuilding know-how.

The Civil War was heating up, and the Union badly needed these boats to control the Mississippi River. Eads promised to deliver what most naval experts thought impossible.

Samuel Pook Created a Floating Fortress Design

Naval architect Samuel Pook drew up plans for what folks called the City-class gunboats. Each boat was 175 feet long and 51 feet wide, with a turtle-shaped design.

The boats had wooden sides sloped at 35 degrees and covered with 2. 5-inch iron plating to bounce off enemy shots.

Thirteen cannons armed each gunboat, with three facing forward, four on each side, and two at the back. The shallow depth of only six feet made these boats perfect for western rivers.

Workers Earned Double Pay for Round-the-Clock Construction

Eads set up a huge making network across four states: Kentucky, Ohio, Illinois, and Missouri. He paid workers $2 for 10-hour days plus extra for overtime, twice the normal wage back then.

Teams worked seven days a week across shipyards in Carondelet, Missouri; Mound City, Illinois; and Cincinnati, Ohio. Eads worked with dozens of suppliers for wood, iron, engines, and other parts.

He even turned existing shops into places that made ship parts.

USS Carondelet Beat the Famous Monitor to the Water

The first of these new boats, USS Carondelet, hit the water on October 12, 1861, making it the first ironclad built in America. This happened three months before the more famous USS Monitor launched in January 1862.

While the Monitor got more news coverage for its fight with the CSS Virginia, the western ironclads played a key role in Union wins. Eads finished all seven gunboats by his 100-day deadline.

A Confederate "Torpedo" Sank USS Cairo in Minutes

USS Cairo joined the Mississippi River Squadron and fought against Confederate strongholds along western rivers.

On December 12, 1862, while clearing mines (called "torpedoes" back then) from the Yazoo River near Vicksburg, trouble struck. Cairo hit an electric mine planted by Confederate fighters.

The blast tore a hole in the hull, and the ironclad sank in just 12 minutes. Not a single crew member died in the sinking.

Nobody Remembered Where the Ironclad Disappeared

After Cairo sank, people forgot where it went down.

The war kept going, Vicksburg fell to Union forces, and the other City-class gunboats kept fighting. The Yazoo River changed course over the years, and mud buried the sunken ironclad.

Civil War veterans died, taking their knowledge with them. Cairo became just another small note in naval history books.

For nearly a century, the boat lay hidden beneath the muddy waters.

Three History Buffs Hunted for the Lost Warship

Vicksburg National Military Park historian Edwin Bearss teamed up with Don Jacks and Warren Grabau in 1956 to look for the lost ironclad.

Bearss spent months studying old maps, battle reports, and newspaper stories to narrow down the search area. The three men mixed their knowledge of Civil War history, geography, and basic science to make a search plan.

They worked on weekends and holidays, using their own money and gear.

A Pocket Compass Led Them to Buried Treasure

The search team used basic tools: a small fishing boat, a pocket compass, and homemade iron bar probes. They noticed the compass needle moved when passing over certain spots in the river, showing large iron masses below.

After finding these magnetic spots, they pushed their iron rods into the mud, hitting metal 36 feet under the surface. On November 12, 1956, they confirmed they had found Cairo.

Mud Preserved Thousands of Civil War Artifacts

The thick Yazoo River mud created perfect keeping conditions for Cairo and its contents. The silt kept away oxygen, stopping rust and decay of over 6,800 items.

Searchers found weapons still loaded, personal items like combs and toothbrushes, medical supplies, clothes, and even bottled pickles still good. Naval gear, tools, and machines stayed in great shape.

This time capsule showed daily life aboard a Civil War vessel.

Raising an Ironclad Required Innovative Techniques

The recovery job ran from 1959 to 1964, needing special gear and new digging methods. Workers first used water jets to clear mud from the hull parts.

They attached lifting straps to the heavy iron pieces and raised them using barges with cranes. The team carefully noted the spot of every item before taking it out.

This recovery became one of the first major underwater dig projects in American history. The job cost over $100,000.

Visitors Can Walk Through Civil War Naval History Today

Congress transferred Cairo’s ownership to the National Park Service in 1972 after years of conservation work. The reconstructed vessel opened to the public in 1977 at Vicksburg National Military Park in Mississippi.

Today, visitors can walk through a covered display featuring the reassembled ironclad and view thousands of artifacts in the adjacent museum.

The Cairo exhibit remains one of the most complete collections of Civil War naval items anywhere.

This remarkable preservation allows modern Americans to connect directly with the technological innovation and daily life of Civil War sailors from over 160 years ago.

Visiting USS Cairo Gunboat, Mississippi

You can see the USS Cairo and its 6,800+ recovered artifacts at Vicksburg National Military Park on 3201 Clay Street. The museum and outdoor gunboat exhibit are open 8:30am-4:30pm daily.

Park entrance costs $20 per vehicle (good for 7 days) and they only accept cards or digital payments, no cash. You can buy passes online at Recreation.
