Never by any chance did he utter a word of abuse against the North. Even when his beloved Arlington was seized, and the swords, pictures, silverware and other precious mementos of Washington were carried off, his protest was couched in quiet and dignified language, well calculated to make those to whom it was addressed (and later every American) blush with shame. Likewise in the heat of battle, when wild tongues were loosed and each side accused the other of all that hate could suggest, he never forgot that his opponents were Americans. "Drive those people back," or "Don't let those people pass you," were the harshest words he ever uttered of his foes. To him war was not a mere license to destroy human life. It was a terrible weapon to be used scientifically, not with the idea of slaughtering as many of the enemy as possible, but to protect the State for whose defense he had drawn his sword. This was distinctly his attitude as he watched Pope's defeated columns reeling from the field. Neither by word nor deed did he exult over the fallen foe or indulge in self-glorification at his expense. His sole thought was to utilize the victory that the war would be speedily brought to a successful close; and, spreading out his maps in the quiet of his tent, he proceeded to study them with this idea. Almost directly in front of his victorious army stretched the intrenchments of Washington but, although he knew something of the panic into which that city had been thrown by the last battle, he had not troops enough to risk assaulting fortifications to the defense of which well-nigh every able-bodied man in the vicinity had been called. The fall of Washington might perhaps have ended the war, but the loss of the neighboring state of Maryland and an attack on some of the Pennsylvania cities, such as Harrisburg and Philadelphia, promised to prove equally effective. The chances of wresting Maryland from the Union seemed particularly favorable, for it had come very close to casting its lot with the Confederacy and thousands of its citizens were serving in the Southern ranks. He, accordingly, made up his mind to march through Maryland, arousing its people to the support of the Confederate cause, and then carry the war into Pennsylvania where a decisive victory might pave the way to an acknowledgment of the independence of the Southern States and satisfactory terms of peace.
