In some unimportant ways I acted as aid for Kilpatrick. A few hundred yards in advance of the main body rode a vanguard of two hundred men, thrown forward to warn us should we strike any considerable number of the enemy's cavalry. As is ever the case, the horses of a small force will walk away from a much larger body, and it was necessary from time to time to send word to the vanguard, ordering it to "slow up." This order was occasionally intrusted to me. I was to gallop over the interval between the two columns, then draw up by the roadside and sit motionless on my horse till the general with his staff came up. The slightest irregularity of action would bring a shot from our own men, while the prospect of an interview with the Johnnies while thus isolated was always good. I saw one of our officers shot that night. He had ridden carelessly into the woods, and rode out again just before the head of the column, without instantly accounting for himself. As it was of vital importance to keep the movement secret as long as possible, the poor fellow was silenced in sad error as to his identity. On we rode, night and day, with the briefest possible halts. At one point we nearly captured a railroad train, and might easily have succeeded had not the station and warehouses been in flames. As it was, the train approached us closely, then backed, the shrieking engine itself giving the impression of being startled to the last degree. On a dreary, drizzling, foggy day we passed a milestone on which was lettered, "Four miles to Richmond." It was still "on to Richmond" with us what seemed a long way further, and then came a considerable period of hesitancy, in which the command was drawn up for the final dash. The enemy shelled a field near us vigorously, but fortunately, or unfortunately, the fog was so dense that neither party could make accurate observations or do much execution. For reasons that have passed into history, the attack was not made. We withdrew six miles from the city and went into camp. I had scarcely begun to enjoy much-needed rest before the Confederates came up in the darkness and shelled us out of such quarters as we had found. We had to leave our boiling coffee behind us--one of the greatest hardships I have ever known. Then followed a long night-ride down the Peninsula, in driving sleet and rain.
