Most Hallowed Ground - 1864

S1, E7: The presidential campaign of 1864 set Abraham Lincoln against his old commanding general, George McClellan. The stakes are nothing less than the survival of the Union itself. Opinion in the North has turned strongly against Lincoln and the war, but 11th-hour Union victories at Mobile Bay, Atlanta and the Shenandoah Valley tilt the election to Lincoln, and the Confederacy's last hope for independence dies. In an ironic twist, Lee's Arlington mansion is turned into a Union military hospital and the estate becomes Arlington National Cemetery -- the Union's most hallowed ground.
