Ironclad ships revolutionised naval warfare in the 19th century. Here we look at their humble beginnings and their sudden demise.

These vessels were covered in iron plates and offered a significant advantage in naval warfare. In this article, we will explore the history of ironclad ships and their significance in the US Civil War.

Origins of Ironclad Ships

The origins of ironclad ships can be traced back to the mid-19th century when the naval powers of Europe began experimenting with iron plating for their warships. The first iron-hulled warship was the French Navy’s Gloire, launched in 1859.

The Gloire was not fully armoured, but it had a protective iron belt along the waterline, which made it more resistant to enemy fire.

The success of the Gloire inspired other navies to build iron-hulled warships, and soon several countries began experimenting with armoured ships. In 1860, the British Navy launched the HMS Warrior, which was the first iron-hulled warship to be fully armoured.

One of the first ironclads was the Royal Navy’s HMS Warrior. It was launched in 1860.

The Warrior had an iron hull and was plated with iron armour that was over four inches thick.

The development of ironclads was driven by a need for warships that could withstand enemy fire. Prior to the development of ironclads, warships were made of wood, which made them vulnerable to enemy fire. As naval guns became more powerful, wooden warships became increasingly vulnerable to canons.

Ironclad ships were a significant improvement over wooden ships because they could withstand shot and mount heavy guns. However, ironclad ships were also more expensive to build and maintain than wooden ships, which meant that they were not as widely adopted by navies.

The American Civil War was a turning point in the development of ironclad ships. Both the Union and Confederate navies recognised the potential of ironclads and began building them during the war.

The success of ironclads during the war demonstrated their effectiveness in naval warfare and led to further development of armoured ships in the years to come.

The American Civil War and Ironclad Ships

The US Civil War broke out in 1861, and both the Union and Confederate navies quickly realised the importance of ironclad ships. The Confederates were at a disadvantage, as they lacked the resources and infrastructure of the Union. They had to rely on existing ships, which they converted into ironclads.

The Union’s first ironclad ship was the USS Monitor, launched on January 30, 1862. The ship was designed by John Ericsson, a Swedish-American engineer. The Monitor was small and compact, with a low profile and a rotating turret that housed two 11-inch Dahlgren guns.

The first battle between true ironclads was in March in 1862 between the CSS Virginia (left) and the USS Monitor.

The ship’s armour consisted of 2.5 inches of iron plates, which made it nearly impervious to enemy fire.

The first major engagement between ironclads took place on March 9, 1862, at the Battle of Hampton Roads. The Confederate navy had converted the USS Merrimack, a wooden frigate, into an ironclad ship called the CSS Virginia.

The Virginia was much larger than the Monitor and was armed with ten guns. The two ships engaged in a fierce battle, but neither was able to sink the other. The engagement demonstrated the effectiveness of ironclad ships and signalled a new era in naval warfare.

The Union and Confederate Ironclad Ships

After the Battle of Hampton Roads, both sides began building more ironclad ships. The Union built a total of 50 ironclads, while the Confederates built around 20. The following is a list of some of the most significant ironclad ships used during the Civil War.

Union Ironclad Ships

  • -USS Monitor (1862) – 987 tons, two 11-inch Dahlgren guns, armour: 2.5 inches of iron plates.
  • -USS Galena (1862) – 950 tons, two 11-inch Dahlgren guns, armour: 2.5 inches of iron plates.
  • -USS New Ironsides (1862) – 3,486 tons, four 11-inch Dahlgren guns, armour: 5 inches of iron plates.
  • -USS Cairo (1862) – 512 tons, six 32-pounder guns, armour: 2.5 inches of iron plates.
  • -USS Tecumseh (1863) – 1,039 tons, two 15-inch guns, armour: 2.5 inches of iron plates.

Confederate Ironclad Ships

  • CSS Virginia (1862) – 4,500 tons, ten guns, armour: 4 inches of iron plates.
  • CSS Arkansas (1862) – 1,160 tons, ten guns, armour: 4 inches of iron plates.
  • CSS Tennessee (1863) – 1,200 tons, six guns, armour: 4 inches of iron plates.
  • CSS Albemarle (1864) – 1,520 tons, four guns, armour: 4 inches of iron plates.

Significance of Ironclad Ships

Ironclad ships had a significant impact on naval warfare during the US Civil War. They were able to withstand enemy fire and could mount heavy guns, which made them effective in attacking enemy vessels and coastal fortifications.

Ironclads could also be used to block harbours and prevent enemy ships from entering or leaving.

One of the most significant actions involving ironclads during the Civil War was the Siege of Vicksburg in 1863. The Union navy used their ironclad ships to attack Confederate fortifications along the Mississippi River.

The Union fleet was able to bypass the Confederate fortifications and effectively cut off supplies to Vicksburg. The siege lasted for several months and ended with the surrender of Confederate forces on July 4, 1863.

Another significant engagement involving ironclads was the Battle of Mobile Bay in 1864. The Union navy had assembled a fleet of ironclad ships, including the USS Tecumseh, USS Chickasaw, USS Manhattan, and USS Winnebago.

The Confederate navy had built the CSS Tennessee, which was their most powerful ironclad ship. The Union fleet engaged the Confederate ships, and after a fierce battle, they were able to capture the CSS Tennessee.

The use of ironclads during the Civil War also had a significant impact on the development of naval technology. After the war, navies around the world began building ironclad ships, which led to further advancements in naval technology.

Beginning of the End of the Ironclad

The demise of the ironclad ship can be attributed to several factors. Despite their effectiveness in naval warfare, ironclad ships were expensive to build and maintain. This made them less attractive to navies that were looking to maximise their resources.

The development of new technologies also played a role in the demise of the ironclad. The invention of the self-propelled torpedo in the late 19th century posed a significant threat to armoured ships.

Torpedoes were cheap to build and could easily sink even the largest battleships. This made it more difficult for navies to justify the cost of building armoured ships.

The development of new gun technologies also made it more difficult for armoured ships to remain effective. The introduction of high-explosive shells in the early 20th century made it easier for enemy ships to penetrate armour. This meant that even heavily armoured ships were vulnerable to enemy fire.

The emergence of new naval powers also contributed to the demise of the ironclad. During the late 19th and early 20th centuries, several countries began expanding their navies and building new warships.

This created a competitive arms race that drove technological advancements in naval warfare. As new technologies were developed, older ships like ironclads became obsolete.

Another factor that contributed to the demise of the ironclad was the changing nature of warfare. As naval warfare evolved, the focus shifted from traditional battleships to submarines and aircraft carriers.

Submarines were highly effective at attacking surface ships, while aircraft carriers provided a new way to project military power across long distances. This meant that armoured ships like ironclads were less relevant in modern naval warfare.

The End

The outbreak of World War I marked the true end of the ironclad era. The war saw the emergence of new technologies like submarines and aircraft carriers, which quickly rendered armoured ships obsolete. During the war, several ironclad ships were sunk by submarines or damaged beyond repair by naval mines.
