On the 21st of July General Patterson, who had been operating with a large union army watching General Joe Johnston's motions around Winchester, fell back from Charlestown to Harper's Ferry. This was the day on which the first battle of Bull Run was fought in which Johnston took an important part, having given the slip to Patterson, who no doubt, was much surprised afterwards to learn that his antagonist was not still at Winchester on that fatal day. Patterson's army occupied Harper's Ferry for several days and helped themselves to most of what was left by the rebels. Whatever may be said of their exploits on the field of battle their achievements in the foraging line are certainly worthy of mention in this and all other impartial histories of that period. The United States army at that time was composed of "three month's men" and certainly, it must be said that if they were not thieves before their enlistment their proficiency in the art of stealing was extraordinary, considering the short time they were learning this accomplishment so necessary or at least so becoming in a thorough campaigner, especially while in an enemy's country. Hen's teeth are articles the scarcity of which is proverbial in all countries, but it can be safely averred that, when this army left Harper's Ferry, the teeth of those useful fowls were as plentiful at that place as any other part of them, and Saint Columbkill himself could not desire more utter destruction to the race of cocks than was inflicted on them at Harper's Ferry by General Patterson's army. Indeed, every thing movable disappeared before them and, at the risk of not being believed, the author will declare that he learned of their carrying off a tombstone from the Methodist cemetery. What they wanted with it he will not venture to guess, but a regard for the truth of history compels him to relate the fact. It may have been that some company cook wanted it for a hearth-stone or it may have been that some pious warrior desired to set it up in his tent as an aid to his devotions, but certain it is that six or eight soldiers of this army were seen by many of the citizens conveying it between them from the cemetery to their bivouac in the armory yard.
