General Thomas J. Jackson's Appearance during the Shenandoah Valley Campaign of 1862, by Robert Catlett Cave

Confederate General Thomas J. "Stonewall" Jackson        His appearance did not impress me as extraordinary. While he did not have the splendid physique, courtly bearing, and gracious manner of General R.E. Lee, he did not strike me as remarkably ungainly in figure, awkward in movement, or rough in demeanor. He did not sit his horse with the easy, graceful, and elegant poise of General Stuart, but he was not uncommonly slouching in the saddle. I did not notice that his uniform looked older and more dingy than those worn by others, or that it bore evidence in accumulated dirt of having been oftener "slept in on the bare ground." His military cap did not appear to be conspicuously "old" and "yellowed," and I did not remark that it was tilted so far forward that he had to "lift his chin in the air to look under the brim." he did not have an "abstracted" and "absent-looking" air; he was not moving his lips as if "wrestling in prayer"; he made no imploring gesture with his hand, as if beckoning Heaven to his aid; and he was not "sucking a lemon." Neither then nor afterwards did I notice the remarkable peculiarities of figure, dress, manner, and habit ascribed to him by some writers in their attempt to make him appear different from other men, and give him the earmarks of genius. To my mind, some of the oddities they attribute to him are suggestive of clownishness and crankiness rather than genius. I am glad that I can remember him without associating him with personal characteristics that really detract from his greatness...
