Concept note-1: -Charleston Harbor, SC | Apr 12-14, 1861. The attack on Fort Sumter marked the official beginning of the American Civil War-a war that lasted four years, cost the lives of more than 620, 000 Americans, and freed 3.9 million enslaved people from bondage.
Concept note-2: -Although Fort Sumter held no strategic value to the North-it was unfinished and its guns faced the sea rather than Confederate shore batteries-it held enormous value as a symbol of the Union. The United States Army began building Fort Sumter on an artificial island at the entrance to Charleston Harbor in 1829.
Concept note-3: -The bombardment of Fort Sumter was the first military action of the American Civil War. Following the surrender, Northerners rallied behind Lincoln’s call for all states to send troops to recapture the forts and preserve the Union.
Concept note-4: -The Confederate victory at the Battle of Fort Sumter resulted in enormous support for military action from both the North and South. President Lincoln called for 75, 000 volunteers to put down the rebellion, while four more states joined the Confederacy.
