The Battle of Fort Sumter was a short, 34‑hour bombardment in April 1861 in Charleston Harbor that ended with a Confederate victory and marked the official start of the American Civil War.

Quick Scoop: What Happened

  • In the early morning of April 12, 1861, Confederate guns around Charleston Harbor opened fire on the Union-held Fort Sumter at about 4:30 a.m., signaling the beginning of the Civil War.
  • The fort was commanded by Union Major Robert Anderson, while the attacking Confederate forces were under Brig. Gen. P. G. T. Beauregard.
  • Confederate batteries from multiple points around the harbor bombarded the fort for roughly 34–36 hours; the small Union garrison was outgunned and running low on supplies.
  • Fires broke out inside the fort, the flagstaff was shot down, and Anderson’s men had little food or ammunition left, making continued resistance untenable.
  • On April 13, Anderson agreed to surrender and evacuate; the Confederates allowed him and his men to leave and even permitted a ceremonial 100‑gun salute to the U.S. flag.
  • Remarkably, no one was killed directly by enemy fire during the battle itself; the only deaths occurred when a gun exploded during the surrender salute, killing two Union soldiers.

Why It Happened

  • Fort Sumter sat in Charleston Harbor, South Carolina, which had seceded and joined the new Confederate States of America, but the fort was still held by U.S. troops.
  • President Abraham Lincoln refused to abandon this federal installation or recognize Confederate independence, while Confederate leaders insisted the fort could not remain under U.S. control inside what they claimed as their territory.
  • Tensions escalated over resupplying the fort; once it was clear the Union would try to hold on, Confederate authorities ordered the bombardment rather than allow the garrison to be reinforced.

Key Outcomes and Significance

  • The battle ended in a clear Confederate victory: they captured Fort Sumter after forcing the Union garrison to withdraw.
  • The firing on Fort Sumter electrified public opinion in both the North and the South, leading both sides to call for volunteers and mobilize for a much larger war.
  • Although “bloodless” in combat terms, this clash opened four years of devastating conflict that would kill over 600,000 Americans.

In short, Fort Sumter was a brief but decisive bombardment: Confederates fired first, the Union surrendered the fort, and the Civil War moved from political crisis to open war.

TL;DR: Confederate forces bombarded the Union garrison at Fort Sumter on April 12–13, 1861, forcing its surrender without major battle casualties, and triggering full-scale Civil War between North and South.
