Civil War soldiers described the experience of combat as both terrifying and confusing. The American writer, Ambrose Bierce, captures both the confusion and terror of the Battle of Shiloh in the below excerpt of his 1881 recollections of the battle.  

Before us ran the turbulent river, vexed with plunging shells and obscured in spots by blue sheets of low-lying smoke. The two little steamers were doing their duty well. They came over to us empty and went back crowded, sitting very low in the water, apparently on the point of capsizing. The farther edge of the water could not be seen; the boats came out of the obscurity, took on their passengers and vanished in the darkness. But on the heights above, the battle was burning brightly enough; a thousand lights kindled and expired in every second of time. There were broad flushings in the sky, against which the branches of the trees showed black. Sudden flames burst out here and there, singly and in dozens. Fleeting streaks of fire crossed over to us by way of welcome. These expired in blinding flashes and fierce little rolls of smoke, attended with the peculiar metallic ring of bursting shells, and followed by the musical humming of the fragments as they struck into the ground on every side, making us wince, but doing little harm. The air was full of noises. To the right and the left the musketry rattled smartly and petulantly; directly in front it sighed and growled. To the experienced ear this meant that the death-line was an arc of which the river was the chord. There were deep, shaking explosions and smart shocks; the whisper of stray bullets and the hurtle of conical shells; the rush of round shot. There were faint, desultory cheers, such as announce a momentary or partial triumph. Occasionally, against the glare behind the trees, could be seen moving black figures, singularly distinct but apparently no longer than a thumb. They seemed to me ludicrously like the figures of demons in old allegorical prints of hell….

The night was now black-dark; as is usual after a battle, it had begun to rain. Still we moved; we were being put into position by somebody. Inch by inch we crept along, treading on one another’s heels by way of keeping together. Commands were passed along the line in whispers; more commonly none were given. When the men had pressed so closely together that they could advance no farther they stood stock-still, sheltering the locks of their rifles with their ponchos. In this position many fell asleep. When those in front suddenly stepped away those in the rear, roused by the tramping, hastened after with such zeal that the line was soon choked again. Evidently the head of the division was being piloted at a snail’s pace by some one who did not feel sure of his ground. Very often we struck our feet against the dead; more frequently against those who still had spirit enough to resent it with a moan. These were lifted carefully to one side and abandoned. Some had sense enough to ask in their weak way for water. Absurd! Their clothes were soaked, their hair dank; their white faces, dimly discernible, were clammy and cold. Besides, none of us had any water. There was plenty coming, though, for before midnight a thunderstorm broke upon us with great violence. The rain, which had for hours been a dull drizzle, fell with a copiousness that stifled us; we moved in running water up to our ankles….

In a few moments we had passed out of the singular oasis that had so marvelously escaped the desolation of battle, and now the evidences of the previous day’s struggle were present in profusion. The ground was tolerably level here, the forest less dense, mostly clear of undergrowth, and occasionally opening out into small natural meadows. Here and there were small pools–mere discs of rainwater with a tinge of blood. Riven and torn with cannon-shot, the trunks of the trees protruded bunches of splinters like hands, the fingers above the wound interlacing with those below. Large branches had been lopped, and hung their green heads to the ground, or swung critically in their netting of vines, as in a hammock. Many had been cut clean off and their masses of foliage seriously impeded the progress of the troops. The bark of these trees, from the root upward to a height of ten or twenty feet, was so thickly pierced with bullets and grape that one could not have laid a hand on it without covering several punctures. None had escaped. How the human body survives a storm like this must be explained by the fact that it is exposed to it but a few moments at a time, whereas these grand old trees had had no one to take their places, from the rising to the going down of the sun. Angular bits of iron, concavo-convex, sticking in the sides of muddy depressions, showed where shells had exploded in their furrows. Knapsacks, canteens, haversacks distended with soaken and swollen biscuits, gaping to disgorge, blankets beaten into the soil by the rain, rifles with bent barrels or splintered stocks, waist-belts, hats and the omnipresent sardine-box–all the wretched debris of the battle still littered the spongy earth as far as one could see, in every direction. Dead horses were everywhere; a few disabled caissons, or limbers, reclining on one elbow, as it were; ammunition wagons standing disconsolate behind four or six sprawling mules. Men? There were men enough; all dead apparently, except one, who lay near where I had halted my platoon to await the slower movement of the line–a Federal sergeant, variously hurt, who had been a fine giant in his time. He lay face upward, taking in his breath in convulsive, rattling snorts, and blowing it out in sputters of froth which crawled creamily down his cheeks, piling itself alongside his neck and ears. A bullet had clipped a groove in his skull, above the temple; from this the brain protruded in bosses, dropping off in flakes and strings. I had not previously known one could get on, even in this unsatisfactory fashion, with so little brain. One of my men whom I knew for a womanish fellow, asked if he should put his bayonet through him. Inexpressibly shocked by the cold-blooded proposal, I told him I thought not; it was unusual, and too many were looking.
