"Don't ask questions. Now you must sit down and eat; you don't know when you will get another meal." At dusk I started. My purpose was to avoid our own pickets and reach before dawn a point opposite the right of the rebel line, which was believed to rest on James River, near or at Mulberry Island, or Mulberry Point; I would then watch for opportunities, and act accordingly, with the view of following up the rebel line, or as near to it as possible. I took no gun or anything whatever to burden me. I was soon outside the guard line of the camp. My way at first was almost due north by the Young's Mill road. Darkness quickly came, and I was glad of it. The stars gave me enough light. My road was good, level, sandy--a lane between two rail fences almost hidden with vines and briers. At my left and behind me I could hear the roar of the surf. When I had gone some two miles, I thought I heard noises ahead, I stopped, and put my ear to the ground. Cavalry. Were they our men, or rebels? I did not want to be seen by either. I slipped into a fence corner. A squad rode by, going toward Hampton, no doubt. I waited until they had passed out of sight, and then rose to continue my tramp, when suddenly, before I had made a step, another horseman rode by, following the others. If he had looked in my direction, he would have seen me; but he passed on with his head straight to the front. I supposed that this last man was on duty as the rear of the squad. Now I tore up my pass into little bits and tossed them away. The party of cavalry which, had passed me, I believed, were our patrol, and that I should find no more of our men; so I was now extremely cautious in going forward, not knowing how soon I might run against some scouting party of the rebels. The road soon diverged far from the shore; the ground was sandy and mostly level; and in many places covered with, a thick, small growth. The imperfect light gave me no extended vision, but from studying the map before I had set out I had some idea of the general character of the country at my right, as well as a pretty accurate notion of the distance I must make before I should come near to the first rebel post; though, of course, I could not know that such post had not been abandoned, or advanced even, within the last few hours. I went on, then, keeping a sharp lookout to right and left and straight ahead, and every now and then stopping to listen. My senses were alert; I thought of nothing but my present purposes; I felt that I was alone and dependent upon myself, but the feeling was not greatly oppressive.
