On November 8, 1861, a U.S. navy warship stopped a British packet and seized two Confederate emissaries on their way to England to seek backing for their cause. England responded with rage, calling for a war of vengeance. The looming crisis was defused by the peace-minded Prince Albert. But imagine how Albert’s absence during this critical moment might have changed everything. For lacking Albert’s calm voice of reason, Britain now seizes the opportunity to attack and conquer a crippled, war-torn America. Ulysses S. Grant is poised for an attack that could smash open the South’s defenses. In Washington, Abraham Lincoln sees a first glimmer of hope that this bloody war might soon end. But then disaster strikes: English troops have invaded from Canada. With most of the Northern troops withdrawn to fight the new enemy, General William Tecumseh Sherman and his weakened army stand alone against the Confederates. Can a divided, bloodied America defeat England, or will the United States cease to exist for all time?
