-- This forenoon, for more than an hour, again long strings of cavalry, several regiments, very fine men and horses, four of five abreast. I saw them in Fourteenth street, coming in town from north. Several hundred extra horses, some of the mares with colts, trotting along. (Appear'd to be a number of prisoners too.).........How inspiriting always the cavalry regiments! Our men are generally well mounted, they ride well, feel good, are young, and gay on the saddle, their blankets in a roll behind them, their sabres clanking at their sides. This noise and movement and the tramp of many horses' hoofs has a curious effect upon one. The bugles play -- presently you hear them afar off, deaden'd, mix'd with other noises.

   Then just as they had all pass'd, a string of ambulances commenced from the other way, moving up Fourteenth street north, slowly wending along, bearing a large lot of wounded to the hospitals.
