Civil War

The American Civil War, also known as the "War Between the States" was fought from 1861 to 1865 between 20 free states of the North and West against 11 slave states of the South that seceded from the Union. 4 border states did not secede but had slavery and provided troops to both sides. The war started in April 1861 at Fort Sumter in Charleston Harbor, South Carolina and effectively ended with the surrender of Robert E. Lee and the Army of Northern Virginia at Appomattox Courthouse in April 1865. The American Civil War is the bloodiest conflict in American history. 

Result: Union Victory
