The 34-hour bombardment that ignited the American Civil War from a harbor fortress
When Major Robert Anderson moved his small Union garrison to Fort Sumter in December 1860, he hoped to secure a defensive position. Instead, he triggered a high-stakes siege. By April 1861, the fort was isolated, undersupplied, and surrounded by Confederate batteries, setting the stage for the war's opening engagement.
The crisis began after South Carolina seceded on December 20, 1860. Major Robert Anderson, commanding U.S. forces in Charleston, moved his men from the vulnerable Fort Moultrie to the unfinished Fort Sumter on December 26. This move was viewed by local authorities as a breach of faith, as they had expected the fort to remain unoccupied. While President James Buchanan attempted to resupply the garrison in January 1861 using the merchant ship Star of the West, the vessel was forced to retreat after being fired upon by shore batteries.
By March 1861, the situation had evolved into a formal siege. Brigadier General P. G. T. Beauregard, appointed by Confederate President Jefferson Davis, arrived in Charleston to organize the harbor's defenses. Meanwhile, newly inaugurated President Abraham Lincoln faced a dilemma: he needed to resupply the starving garrison without appearing as the aggressor. When Lincoln announced he would send provisions, the Confederate government demanded an immediate evacuation. Anderson refused, and at 4:30 a.m. on April 12, 1861, Confederate batteries opened fire.
The bombardment lasted 34 hours. The fort, designed to defend against naval attacks, was ill-equipped to handle land-based artillery, and its guns were largely aimed at the Atlantic. With supplies dwindling and wooden barracks set ablaze by heated shot, Anderson surrendered on April 14. Remarkably, no one died during the engagement, though two soldiers were killed in a gun explosion during the surrender ceremony. The battle prompted Lincoln to call for 75,000 volunteers, leading four more states to secede and marking the definitive start of the American Civil War.
