When the general and his staff, which I have described above, were well nigh Brightwood, he halted to inquire, of the alarmed negroes and straggling citizens who were wending their way into the city, what news they had of the enemy outside. But no trustworthy information could he get from any of them. They all knew that General Early was coming; and that they had left just before he had got to where they lived. This sort of information was not exactly the kind a general would consider it safe to base his plan of operations on. Nor was the general any more fortunate in getting information concerning the enemy from a number of squads of cavalry, whose business it seemed to be to ride excitedly to the front and then ride excitedly back again. Indeed, the whole business of these doughty troopers, it seemed to me, was to increase the alarm and confusion. It was nearly sundown, the weather was hot and oppressive, and the general was full of troubles. The worst of these was that he could not find the troops he was sent to command. Nor could he get any tidings concerning General Early and his rebels. Hence it was that he concluded, and very naturally, that the enemy would not be within sight of the defenses until morning, and that the city would at least be safe until that time without any more of his generalship. He therefore went into camp for the night, pitching his headquarters in a clump of wood near Rock Creek, and not far from Crystal Spring. And here let me record that the general had not even a camp guard. To make the matter worse, there was no forage for the horses, and nothing for supper. Never was general so much to be pitied. The two orderlies, however, were willing fellows, and soon had a fire lighted. They then proceeded to a neighboring house, and got refreshments for the general, without which he must have gone hungry to bed. As the night advanced, the discomforts of the situation increased. In short, it may as well be confessed, the general's headquarters were besieged long before midnight, and that sleep was a thing not to be enjoyed. You may have made up your mind that the besiegers were an advance guard of the rebels; but they were not. They were nothing less than an army of fierce musquitoes, who made such a persistent attack on the general and his staff as to make his position almost untenable. In truth, they so harassed the corpulent engineer, in rear and flank, that he mounted his horse and returned to the city, where he spent a comfortable night at Willard's Hotel, and went back in the morning refreshed. My authority for this is the distinguished engineer himself.
