Summary: In Part IV of the American Civil War the nation reels from the cost of the conflict. The Battle of Antietam takes its toll as the nation's bloodiest single day of combat - ever. The Battle of Gettysburg becomes the country's most costly single battle, still to this day. The Union army control is given to Ulysses S. Grant who battles Robert E. Lee through the Overland Campaign, inching closer to Richmond where the life of the Confederate States of America seems to be waning.
