The Battle of Fort Sumter was the deadliest battle of the Civil War. It occurred on April 12, 1860. Following the secession of Virginia, Union forces still occupied forts along the state's coastline and refused calls to evacuate. Union General Ricahrd Anderson moved his soldiers from Fort Knox to Fort Sumter because he thought it would be easier to defend. At least two Union ships were fired upon as they tried to bring reinforcements to the soldiers trapped in the fort. In the early morning of April 12th, Confederate forces led by Stonewall Jackson began bombarding the fort. Anderson's men held out for 34 hours before surrendering. As a result of the Union victory, President Buchanan called for the mobilization of 75,000 soldiers, which resulted in the secession oftwo additional states. The Civil War had begun.
