General Lee and the remnant of the Army of Northern Virginia continued the fight until they were surrounded, outnumbered and without hope of reinforcements or food rations for the starving army.
On April 9, 1865, Robert E. Lee met Ulysses S. Grant at Appomattox Court House, Virginia to surrender his Army of Northern Virginia. There were other Confederate Armies in the field but this effectively marked the end of the Civil War.
President Abraham Lincoln was shot by John Wilkes Booth at Ford’s Theater in Washington, D.C. on April 14, 1865 and died the following morning. The North went into mourning and many in the South realized that the best hope for a fair reconciliation with the North died with him.
There were over 620,000 deaths in the Civil War, making it the costliest war in American history.
