Nathan Bedford Forrest … used his horsemen as a modern general would use motorized infantry. He liked horses because he liked fast movement, and his mounted men could get from here to there much faster than any infantry could; but when they reached the field they usually tied their horses to trees and fought on foot, and they were as good as the very best infantry. Not for nothing did Forrest say the essence of strategy was to git thar fust with the most men.

Beneath everything else, North and West, there ran a profound, unvoiced, almost subconscious conviction that the [American] nation was going to go on growing-in size, in power, in everything a man could think of-and in that belief there was a might and a fury that would take form instantly at the moment of shock.
