The war correspondent of the Columbus (GA) Times penned the following descriptions of what Lee, Longstreet, and Jackson looked like following their campaign into Maryland. It was reprinted in numerous papers, but this article has been pulled from the November 4, 1862 issue of the Staunton Spectator (VA).

General Longstreet is stout and fleshy, and of good height, and has a quiet courageous look. He seems full of thought and of decision, and his face makes an agreeable impression alike on new and old acquaintances. He is characteristically a fighting man--none can equal him in forcing a strong and well fortified position, and General Lee showed his appreciation of an old tried soldier, when he patted him on the shoulder after the late battle and said, "My old war horse!" In this engagement he was second in command of the army, and his old corps keenly felt the need of his able handling.
I was surprised at Stonewall Jackson's appearance. He has been described as a sort of clown. I never yet saw him riding with his knees drawn up like a monkey, and his head resting upon his breast. He has a first rate face, and seems a plainly dressed Captain of Cavalry, with an unpretending Staff. His uniform is fine enough, certainly, for the hard life he leads. But the imagination, is piqued, you know, by the absence of pretension, as "a King in grey clothes." Stonewall can't like to come about the army much. The boys keep him bareheaded all the time. When they begin to cheer him he usually pulls off his hat, spurs his fine horse, and runs through, greeted with cheers every step for five miles.
