I resolved to mark it by some token of recognition, which could be no other than a salute of arms. Well aware of the responsibility assumed, and of the criticisms that would follow, as the sequel proved, nothing of that kind could move me in the least. The act could be defended, if needful, by the suggestion that such a salute was not to the cause for which the flag of the Confederacy stood, but to its going down before the flag of the Union. My main reason, however, was one for which I sought no authority nor asked forgiveness. Before us in proud humiliation stood the embodiment of manhood: men whom neither toils and sufferings, nor the fact of death, nor disaster, nor hopelessness could bend from their resolve; standing before us now, thin, worn, and famished, but erect, and with eyes looking level into ours, waking memories that bound us together as no other bond;–was not such manhood to be welcomed back into a Union so tested and assured?”

“The General was riding in advance of his troops, his chin drooped to his breast, downhearted and dejected in appearance almost beyond description. At the sound of that machine like snap of arms, however, General Gordon started, caught in a moment its significance, and instantly assumed the finest attitude of a soldier. He wheeled his horse facing me, touching him gently with the spur, so that the animal slightly reared, and as he wheeled, horse and rider made one motion, the horse’s head swung down with a graceful bow, and General Gordon dropped his swordpoint to his toe in salutation.
