On April 9, 1865, General Robert E. Lee surrendered the Confederate Army of Northern Virginia to Union General Ulysses S. Grant at Appomattox Court House in Virginia.

This event marked a pivotal moment in the Civil War, effectively signaling the end of the conflict in the Eastern Theater. The surrender was a significant step towards the reunification of the nation, as it prompted other Confederate forces to surrender in the following weeks, leading to the eventual conclusion of the war.
