When Lincoln subsequently meets with the Confederates, he tells them that slavery cannot be restored as the North is united for ratification of the amendment, and that several of the southern states' reconstructed legislatures would also vote to ratify. On April 3, Lincoln visits the battlefield at Petersburg, Virginia, where he exchanges a few words with Lieutenant General Ulysses S. Grant. Six days later, Grant receives General Robert E. Lee's surrender at Appomattox Courthouse.
