Ken Burns The Civil War - Most Hallowed Ground (1864)

Streaming video - 2015

The episode begins with the presidential election of 1864 that sets Abraham Lincoln against his old commanding general, George McClellan. The stakes are nothing less than the survival of the Union itself: with Grant and Sherman stalled at Petersburg and Atlanta, opinion in the North has turned strongly against the war. But 11th-hour 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, poignantly typical of the Civil War, Lee’s Arlington mansion is turned into a Union military hospital and the estate becomes Arlington National Cemetery, the Union’s most hallowed ground.
