The South's defeat in the Civil War.

General Lee's surrender in 1865 marked the South's defeat in the Civil War.

Explanation:

Robert E. Lee was until 1861 Colonel of the US Army and the most successful general of the Confederate Army. His most important command during the Civil War was the supreme command of the Northern Virginia Army. Finally, in January 1865, he was appointed Commander-in-Chief of the Confederate Army. He established his fame with numerous victories, which he won with inferior forces mostly by shifting the focus against superior forces.  But a series of defeats marked that the Confederation was no longer holding its position, and in 1865, Lee surrendered his troops at Appomattox Court House, which marked the end of the Civil War and the defeat of the South.
