General Lee surrenders to General U.S. Grant at Appomattox in April of 1865

I know this is some years late but I hope that it helps others that need may need it.

Explanation: On April 9, 1865, near the town of Appomattox Court House, Virginia, Confederate General Robert E. Lee surrendered his Army of Northern Virginia to Union General Ulysses S. Grant. ...
