Getting my bearings again with some difficulty, I now made a wide detour to the left, in the hope of passing around this outpost and striking the river beyond. In this mad attempt I ran upon a more vigilant sentinel, posted in the heart of a thicket, who fired at me without challenge. To a soldier an unexpected shot ringing out at dead of night is fraught with an awful significance. In my circumstances--cut off from my comrades, groping about an unknown country, surrounded by invisible perils which such a signal would call into eager activity--the flash and shock of that firearm were unspeakably dreadful! In any case I should and ought to have fled, and did so; but how much or little of conscious prudence there was in the prompting I do not care to discover by analysis of memory. I went back into the corn, found the river, followed it back a long way and mounted into the fork of a low tree. There I perched until the dawn, a most uncomfortable bird. In the gray light of the morning I discovered that I was opposite an island of considerable length, separated from the mainland by a narrow and shallow channel, which I promptly waded. The island was low and flat, covered with an almost impenetrable cane-brake interlaced with vines. Working my way through these to the other side, I obtained another look at God's country--Shermany, so to speak. There were no visible inhabitants. The forest and the water met. This did not deter me. For the chill of the water I had no further care, and laying off my boots and outer clothing I prepared to swim. A strange thing now occurred--more accurately, a familiar thing occurred at a strange moment. A black cloud seemed to pass before my eyes--the water, the trees, the sky, all vanished in a profound darkness. I heard the roaring of a great cataract, felt the earth sinking from beneath my feet. Then I heard and felt no more. At the battle of Kennesaw Mountain in the previous June I had been badly wounded in the head, and for three months was incapacitated for service. In truth, I had done no actual duty since, being then, as for many years afterward, subject to fits of fainting, sometimes without assignable immediate cause, but mostly when suffering from exposure, excitement or excessive fatigue. This combination of them all had broken me down--most opportunely, it would seem.
