Civil War Siege Campaigns: The Battle for Charleston

Charleston, South Carolina — The Most Contested City of the Civil War

Charleston: The City That Fired the First Shot

No city in American history bears a more charged relationship with the Civil War than Charleston, South Carolina. It was here, at the Convention Hall on Meeting Street on December 20, 1860, that South Carolina voted to become the first state to secede from the United States — setting in motion a chain of events that would lead to the bloodiest conflict in American history. And it was here, on April 12, 1861, that the first shots of the Civil War rang out across the harbor as Confederate artillery opened fire on the federal garrison at Fort Sumter.

From first shot to final evacuation, Charleston stood at the heart of the Confederate experience. The city that launched the war endured one of its longest and most complex military sieges, holding out against Union naval and land forces from the summer of 1863 until February 1865 — a remarkable 587-day defense that became a symbol of Confederate tenacity and military engineering skill.

The Confederate Museum, housed in the historic Market Hall where many of these soldiers began their service, preserves the material legacy of Charleston's Civil War experience. Its collection of artifacts, documents, and personal effects provides an intimate window into the lives of the men who defended the city and the women who supported them through four years of war.

The Defense of Charleston Harbor

Charleston Harbor presented natural advantages for defense that Confederate engineers exploited brilliantly. The harbor entrance was controlled by a network of islands and shoals that channeled approaching vessels into narrow, fortified passages. At the mouth of the harbor sat Morris Island to the south and Sullivan's Island to the north, each bristling with Confederate artillery. In the middle of the harbor, Fort Sumter stood as the anchor of the entire defensive system.

When Union Admiral Samuel F. Du Pont launched a major naval assault with nine ironclad warships on April 7, 1863, he expected to quickly overwhelm the Confederate defenses and open the harbor. Instead, Confederate gunners — firing with precision from the harbor forts — disabled all nine vessels in under two hours of fierce combat. Du Pont's defeat ended any hope of a quick naval solution and forced Union planners to consider a long-term siege strategy.

Fort Wagner and the 54th Massachusetts

With the naval approach blocked, Union forces shifted their attention to Morris Island, whose possession would allow them to bombard Fort Sumter at close range. The key to Morris Island was Battery Wagner, a massive earthwork fortification at the island's northern tip. Earthen fortifications like Wagner were proving remarkably resistant to artillery fire — cannon balls and shells simply buried themselves in the sand and earth rather than shattering masonry walls.

On the night of July 18, 1863, Union forces launched a frontal assault on Battery Wagner. Leading the charge was the 54th Massachusetts Infantry, one of the first African American regiments organized in the North. Colonel Robert Gould Shaw, commanding the regiment, led his men across 600 yards of open beach under devastating Confederate fire. The assault reached the parapet but could not be maintained, and Shaw was killed along with nearly half his regiment. The failed attack became one of the most celebrated military actions of the Civil War, commemorated in Augustus Saint-Gaudens' famous relief memorial on Boston Common.

The Long Bombardment of Fort Sumter

Unable to take Wagner by storm, Union forces settled in for a siege. Through August and September 1863, Union artillery systematically reduced Battery Wagner to rubble, and Confederate forces evacuated the position on September 7, 1863. But Fort Sumter, which Union guns had been pounding since August 17, proved far more resilient.

Union artillery fired more than 5 million pounds of projectiles at Fort Sumter during the siege — reducing its brick walls to a formless rubble mound. Yet Confederate engineers transformed the rubble into an even more effective defensive position. Working at night under fire, Confederate labor crews rebuilt the fort's interior with new traverses and bombproofs, turning Sumter into an almost indestructible fortification. By the end of the siege, the fort had been hit by more than 3,500 projectiles and still flew the Confederate flag.

Daily Life in Besieged Charleston

While the harbor battles raged, the civilian population of Charleston experienced the siege in ways that combined routine and terror. Union batteries on Morris Island were close enough to shell not just the harbor fortifications but the city itself. Beginning in August 1863, Union forces deliberately bombarded civilian neighborhoods in Charleston, particularly the lower wards near the Battery, in an attempt to break Confederate morale and force an evacuation.

The civilian response was a combination of evacuation and adaptation. Many wealthy families moved to plantations in the interior of the state or to Columbia and other inland cities. Those who remained learned to live in the northern portions of the city, away from the most dangerous zones of fire. The Confederate Museum's collection of letters and diaries from this period documents the strange rhythms of life in a besieged city — attending church despite nearby explosions, worrying about family members in the field, and maintaining the routines of daily life against a backdrop of constant threat.

The H.L. Hunley: Confederate Innovation Under Pressure

The pressures of the Charleston siege drove Confederate ingenuity in unexpected directions. Unable to challenge Union naval supremacy directly, Confederate engineers in Charleston developed new weapons technology that would have lasting implications for naval warfare. The most dramatic of these was the H.L. Hunley, a hand-powered submarine that became the first submarine in history to sink an enemy warship.

On February 17, 1864, the Hunley attacked the Union blockade vessel USS Housatonic and sank it with a spar torpedo — a bomb on the end of a long pole attached to the submarine's bow. The Hunley itself disappeared shortly afterward and was not found until 1995, when a search team located it buried in the harbor mud. The vessel is now preserved and on display at the Warren Lasch Conservation Center in North Charleston, one of the most significant Civil War artifacts in existence.

The Fall of Charleston

The Confederate evacuation of Charleston came not from military defeat at the hands of the siege forces, but from a strategic necessity imposed by General William T. Sherman's devastating march through the Carolinas. As Sherman's army swept northward through South Carolina in early 1865, it threatened to sever the railroad connections that kept Charleston supplied. With the city facing isolation, Confederate commander General William Hardee ordered the evacuation on February 17, 1865.

Confederate forces destroyed military supplies and equipment before departing, and fires broke out in parts of the city. Union forces — including African American troops who had fought to reach this moment — entered Charleston on February 18, 1865. On April 14, 1865 — four years to the day after Fort Sumter had surrendered — a ceremony was held at the fort to raise the same United States flag that had been lowered in 1861.

The artifacts preserved in The Confederate Museum are a testament to the men and women who lived through this history. Visiting the museum today, in the very building where many of those soldiers received their orders before marching out to the harbor forts, connects us to this story in a direct and immediate way that no secondary account can match.
