As a member of Colonel Post's staff, I was naturally favored with a good view of the performance. We formed in line of battle at a distance of perhaps a half-mile from the bridge-head, but that unending column of gray and steel gave us no more attention than if we had been a crowd of farmer-folk. Why should it? It had only to face to the left to be itself a line of battle. Meantime it had more urgent business on hand than brushing away a small brigade whose only offense was curiosity; it was making for Spring Hill with all its legs and wheels. Hour after hour we watched that unceasing flow of infantry and artillery toward the rear of our army. It was an unnerving spectacle, yet we never for a moment doubted that, acting on the intelligence supplied by our succession of couriers, our entire force was moving rapidly to the point of contact. The battle of Spring Hill was obviously decreed. Obviously, too, our brigade of observation would be among the last to have a hand in it. The thought annoyed us, made us restless and resentful. Our mounted men rode forward and back behind the line, nervous and distressed; the men in the ranks sought relief in frequent changes of posture, in shifting their weight from one leg to the other, in needless inspection of their weapons and in that unfailing resource of the discontented soldier, audible damning of those in the saddles of authority. But never for more than a moment at a time did anyone remove his eyes from that fascinating and portentous pageant.
