As Lee rode toward Appomattox Court House on April 9, 1865, Longstreet said, "General, if he does not give us good terms, come back and let us fight it out." But General Grant, Longstreet's best friend at West Point and in the antebellum army, offered generous terms, and it was over, at a cost of more than 620,000 American lives. 

At Appomattox, Longstreet was warmly received by Grant, and their friendship from before the war continued. Longstreet never saw Robert E. Lee again, although they did exchange letters prior to Lee's death in 1870.
