“A bridle upon the city.” That’s how the London Times described Castle Pinckney just before the Civil War. But what does it mean?
Welcome to Castle Pinckney, a small masonry fortification in Charleston Harbor. It played a surprisingly important role in American history. Castle Pinckney stands on Shutes Folly, a small island about one mile off the Charleston shore.
Let’s step back to the late 1790s. War with France seemed possible. The US government decided to build a fort on this island to protect Charleston. They named it Fort Pinckney after Charles Cotesworth Pinckney, a Revolutionary War hero. Completed in 1804, this first fort was made of logs and earth. Sadly, a severe hurricane destroyed it just months later.
Undeterred, the government built a replacement between 1809 and 1810. This time, it was a brick-and-mortar structure and called Castle Pinckney. It was garrisoned throughout the War of 1812, but it never saw any action. Afterwards, the Castle Pinckney was abandoned and fell into disrepair.
But Castle Pinckney’s story doesn’t end there. During the Nullification Crisis of 1832, President Andrew Jackson threatened to use military force to collect a controversial tariff. Castle Pinckney was re-garrisoned. The fort was primarily a storehouse for gunpowder and other military supplies.
By the late 1850s, Castle Pinckney was part of a network of defensive positions in the harbor. These included Fort Sumter and Fort Moultrie. In 1860, Castle Pinckney had fourteen 24-pounders, four 42-pounders, four 8-inch howitzers, one 10-inch and one 8-inch mortar, and four light field pieces.
Here comes the interesting fact: On December 27, 1860, South Carolina seceded from the Union. One week later, South Carolina militia seized Castle Pinckney from its small US Army garrison. It was the first Federal military installation seized by a Southern state government.
After the Confederate attack on Fort Sumter, the Charleston Zouave Cadets garrisoned Castle Pinckney. Union prisoners of war were held here. These prisoners had been captured during the First Battle of Bull Run. According to the Charleston Mercury, these prisoners were selected because they were the most insolent and insubordinate. They were allowed to wander during the day and were confined to cells only at night.
However, the Castle Pinckney proved to be too small for permanent confinement. After six weeks, the prisoners were moved back to the Charleston City Jail. Later, after a fire damaged the jail, the prisoners were briefly returned to the island.
Some sources say that Castle Pinckney never fired a single hostile shot during its existence. In 1890, parts of the old brick walls were dismantled to make way for a harbor lighthouse. There was local opposition. Some wanted to build a retirement home for servicemen on the island instead.
Castle Pinckney was declared a U.S. National Monument in 1924. But this status was removed in 1951. The island was sold to the State Ports Commission in 1958. There were even plans for a private residence, a nightclub, and a restaurant. A local Sons of Confederate Veterans post took over management in the late 1960s.
Castle Pinckney was listed on the National Register of Historic Places in 1970. Today, Castle Pinckney stands as a ruin. It is a testament to the tides of history. Its location makes access difficult. Nature is gradually reclaiming it. But its story remains. It is a story of defense, conflict, and a nation divided. Remember Castle Pinckney. It was the first Federal installation to fall in the Civil War.
