On this day (6/2) in 1865: In an event that is generally regarded as marking the end of the Civil War, Confederate General Edmund Kirby Smith, commander of Confederate forces west of the Mississippi, signs the surrender terms offered by Union negotiators. With Smith's surrender, the last Confederate army ceased to exist, bringing a formal end to the bloodiest four years in U.S. history. The American Civil War began on April 12, 1861, when Confederate shore batteries under General Pierre G.T. Beauregard opened fire on Union-held Fort Sumter in South Carolina's Charleston Bay. During 34 hours, 50 Confederate guns and mortars launched more than 4,000 rounds at the poorly supplied fort, and on April 13 U.S. Major Robert Anderson, commander of the Union garrison, surrendered. Two days later, U.S. President Abraham Lincoln issued a proclamation calling for 75,000 volunteer soldiers to help quell the Southern "insurrection." Four long years later, the Confederacy was defeated at the total cost of 620,000 Union and Confederate dead.
Hmmm.... I've always though Lee's surrender to Grant at Appomattox, VA, signaled the end of the Civil War, but that was 4/7/1865, almost 2 months earlier. I guess news didn't travel as quickly back then.
