"But tell me, at least, the history of the four days preceding your arrest."
"I will. Let me see—this is Friday. Well, until this morning's fatal sleep, I had not slept since Sunday night. Monday was passed in the usual routine of military duty. Monday evening I was sent on a reconnoitering expedition to the old castellated Spanish fort of the Casa de Mata, that occupied the whole night. On Tuesday morning I was selected to attend the messenger who went with the flag of truce into the city to carry our General's letter of expostulation to Santa Anna, which employed the whole day. On Tuesday night, without having had an hour's rest in the interval, I was put on guard. Wednesday morning I was sent with a party to escort an emigrant caravan across the marsh to the village of Churubusco. Wednesday afternoon you saw me on guard and I told you that I had not slept one hour for three days and nights."
"Yes, you looked ill enough to be ordered on the sick list."
"Yet, listen. Thoroughly exhausted as I was, on Wednesday night I was ordered to join a party to go on a secret reconnoitering expedition to the Molina-del-Rey. On Thursday morning I was sent out with another party on a foraging tour. On Thursday night I was sent in attendance upon the officer who carried despatches to General Quitman. On Friday morning I was set on guard between the hours of four and eight!"
"Oh, heaven, what an infamous abuse of military authority!" exclaimed Herbert, indignantly.
"Herbert, in my life I have sometimes suffered with hunger, cold and pain, and have some idea of what starving, freezing and torture may be, but among all the ills to which flesh is heir, I doubt if there is one so trying to the nerves and brain of man as enforced and long-continued vigilance, when all his failing nature sinks for want of sleep. Insanity and death must soon be the result."
"Humph! Go on. Tell me about the manner of their finding you," said Herbert, scarcely able to repress his indignation.
"Well, when after—let me see—eighty-four—ninety—ninety-six hours of incessant watching, riding and walking, I was set on guard to keep the morning watch between four o'clock and eight, 'my whole head was sick and my whole heart faint'; my frame was sinking; my soul could scarcely hold my body upright. In addition to this physical suffering was the mental anguish of feeling that these men had resolved upon my death, and thinking of my dear mother and Clara, whose hearts would be broken by my fall. Oh! the thought of them at this moment quite unmans me. I must not reflect. Well, I endeavored with all the faculties of my mind and body to keep awake. I kept steadily pacing to and fro, though I could scarcely drag one limb after the other, or even stand upright; sleep would arrest me while in motion, and I would drop my musket and wake up in a panic, with the impression of some awful, overhanging ruin appalling my soul. Herbert, will you think me a miserably weak wretch if I tell you that that night was a night of mental and physical horrors? Brain and nerves seemed in a state of disorganization; thought and emotion were chaos; the relations of soul and body broken up. I had but one strong, clear idea, namely, that I must keep awake at all costs, or bring shameful death upon myself and disgrace upon my family. And even in the very midst of thinking this I would fall asleep."
"No power within yourself could have prevented it; indeed, you had to drop into sleep or death!"
"I pinched myself, I cut my flesh, I burned my skin, but all in vain. Nothing could withstand the overwhelming power of sleep that finally conquered me, about five o'clock this morning. Then, in the midst of a delightful dream of mother and Clara and home, I was roused up by a rude shake, and awoke to find my musket fallen from my hands, and my Captain and Colonel standing over me. It was several minutes before I could travel back from the pleasant land of sleep and dreams and realize my real position. When I did I had nothing to say. The inevitable ruin I felt had come, and crushed me into a sort of dumb despair. Nor did my superior officers reproach me—their revenge was too perfect. The captain called a sergeant to take my gun, and I was marched off to my present prison. And, Herbert, no sooner was I left alone here than sleep overcame me again, like a strong man, and despite all the gloom and terror of my situation, despite all my thoughts of home and mother and Clara, I slept like a tired child. But this awakening. Oh! this awakening, Herbert!"
