In a conversation the other day a person made the observation that "corruption" is taxation where formal taxation structures don't exist.

In that context, In the newly developing "war between nations" (as opposed to war between Kingdoms), where the will/morale and ability of the populace to support a war is so critical to achieving true defeat, deep raids targeting that aspect of the populace were "strategic bombing" before bombers existed.

Grant sent Sheridan into the Shenandoah on the same mission, though the history books seem to focus on Sherman; and all seem to miss that it was on Grant's orders to execute Grant's strategy that both these trusted lieutenants acted.

Grant had a comprehensive grasp on the realities of modern warfighting as it was developing around him, that great tactical leaders like Lee did not appear to grasp. I suspect that if Grant had focused solely on the defeat of Lee's army or the capture of Richmond that the war would have been much more likely to have devolved into a decades long insurgency.
