Overview: The third part recalls 1863, when opposition to the Civil War spread among Northerners: some see the high level of casualties as unacceptable, while others resent fighting to free black slaves.

The final 16 months of the Civil War are charted, including the battle at Gettysburg and Abraham Lincoln's battlefield dedication and, just days after the South's surrender at Appomattox, his assassination. Included: Abraham's dedication to bringing the South into the Union; Mary's private wish for revenge.
