After dark I set out from Cashtown to gain the head of the column during the night. My orders had been peremptory that there should be no halt for any cause whatever. If an accident should happen to any vehicle, it was immediately to be put out of the road and abandoned. The column moved rapidly, considering the rough roads and the darkness, and from almost every wagon for many miles issued heart-rending wails of agony. For four hours I hurried forward on my way to the front, and in all that time I was never out of hearing of the groans and cries of the wounded and dying. Scarcely one in a hundred had received adequate surgical aid, owing to the demands on the hard-working surgeons from still worse cases that had to be left behind. Many of the wounded in the wagons had been without food for thirty-six hours.
Their torn and bloody clothing, matted and hardened, was rasping the tender, inflamed, and still oozing wounds. Very few of the wagons had even a layer of straw in them, and all were without springs. The road was rough and rocky from the heavy washings of the preceding day. The jolting was enough to have killed strong men, if long exposed to it. From nearly every wagon as the teams trotted on, urged by whip and shout, came such cries and shrieks as these:
'O God! Why can't I die!'
'My God! Will no one have mercy and kill me!'
'Stop! Oh! For God's sake, stop just for one minute; take me out and leave me to die on the roadside.'
'I am dying! I am dying! My poor wife, my dear children, what will become of you?'
Some were simply moaning; some were praying, and others uttering the most fearful oaths and execrations that despair and agony could wring from them; while a majority, with a stoicism sustained by sublime devotion to the cause they fought for, endured without complaint unspeakable tortures, and even spoke words of cheer and comfort to their unhappy comrades of less will or more acute nerves. Occasionally a wagon would be passed from which only low, deep moans could be heard. No help could be rendered to any of the sufferers. No heed could be given to any of their appeals. Mercy and duty to the many forbade the loss of a moment in the vain effort then and there to comply with the prayers of the few. On! On! we must move on. The storm continued, and the darkness was appalling. There was no time even to fill a canteen with water for a dying man; for, except the drivers and the guards, all were wounded and utterly helpless in that vast procession of misery. During this one night I realized more of the horrors of war than I had in all the two preceding years.
