Others slept in their saddles, either leaning forward on the pommel of the saddle, or on the roll of coat and blanket, or sitting quite erect, with an occasional bow forward or to the right or left, like the swaying of a flag on a signal station, or like the careerings of a drunken man. The horse of such a sleeping man will seldom leave his place in the column, though this will sometimes occur, and the man awakes at last to find himself alone with his horse which is grazing along some unknown field or woods. Some men, having lost the column in this way, have fallen into the enemy's hands. Sometimes a fast-walking horse in one of the rear companies will bear his sleeping lord quickly along, forcing his way through the ranks ahead of him, until the poor fellow is awakened, and finds himself just passing by the colonel and his staff at the head of the column! Of course, he falls back to his old place somewhat confused and ashamed, and the occurrence lends him just excitement enough to keep him awake for a few minutes. It is seldom that men under these somnambulic circumstances fall from their horses, yet sometimes it does happen, and headlong goes the cavalier upon the hard ground, or into a splashing mud-puddle, while general merriment is produced among the lookers-on. But as no one is seriously injured, the "fallen brave" retakes his position in the ranks and the column proceeds as though nothing had happened. We had all these experiences in one form or another in our raid, and on reaching camp we found that several men had lost their caps by the way. The day following our arrival at camp the general in command issued his complimentary message, namely: HEADQUARTERS ARMY OF VIRGINIA, Washington, July 21. _To Hon. E. M. Stanton, Secretary of War_: SIR: The cavalry expedition I directed General King to send out on the nineteenth instant has returned. They left Fredericksburg at seven P. M., on the nineteenth, and after a forced march during the night made a descent at daylight in the morning upon the Virginia Central Railroad at Beaver Dam Creek, twenty-five miles north of Hanover Junction and thirty-five miles from Richmond. They destroyed the railroad and telegraph line for several miles, burned the depot, which contained forty thousand rounds of other musket ammunition, one hundred barrels of flour, and much valuable property, and brought in the Captain in charge as a prisoner. The whole country round was thrown into a great state of alarm. One private was wounded on our side. The cavalry marched eighty miles in thirty hours. The affair was most successful, and reflects high credit upon the commanding officer and his troops. As soon as full particulars are received I will transmit to you the name of the commanding officer of the troops engaged.
