Watched it.
Very well done and accurate.
The thing that Grant (and Sherman) ushered in was the concept of modern warfare. The civilians were no longer just observers and the fighting didn't just take place on the battlefield.
Had they not broken civilian support for the Confederacy, the war could have gone on much longer.
And Grant was dogged in his pursuit of Lee and the Army of Virginia.
As long as you still have an army in the field, you can continue to fight.
Grant understood that, and went after Lee while the previous Union generals preferred to wait until they felt assured of victory.
