After his great victories at Gettysburg and Union Mills, General Robert E. Lee’s attempt to bring the war to a final conclusion by attacking Washington, D.C., fails. However, in securing Washington, the remnants of the valiant Union Army of the Potomac, under the command of the impetuous General Dan Sickles, is trapped and destroyed. For Lincoln there is only one hope left: that General Ulysses S. Grant can save the Union cause. It is now August 22, 1863. Lincoln and Grant are facing a collapse of political will to continue the fight to preserve the Union. Lee, desperately short of manpower, must conserve his remaining strength while maneuvering for the killing blow that will take Grant’s army out of the fight and, at last, bring a final and complete victory for the South.
