As already stated, it was never my intention to remain in the army long, but to prepare myself for a professorship in some college. Accordingly, soon after I was settled at Jefferson Barracks, I wrote a letter to Professor Church—Professor of Mathematics at West Point—requesting him to ask my designation as his assistant, when next a detail had to be made. Assistant professors at West Point are all officers of the army, supposed to be selected for their special fitness for the particular branch of study they are assigned to teach. The answer from Professor Church was entirely satisfactory, and no doubt I should have been detailed a year or two later but for the Mexican War coming on. Accordingly I laid out for myself a course of studies to be pursued in garrison, with regularity, if not persistency. I reviewed my West Point course of mathematics during the seven months at Jefferson Barracks, and read many valuable historical works, besides an occasional novel. To help my memory I kept a book in which I would write up, from time to time, my recollections of all I had read since last posting it. When the regiment was ordered away, I being absent at the time, my effects were packed up by Lieutenant Haslett, of the 4th infantry, and taken along. I never saw my journal after, nor did I ever keep another, except for a portion of the time while travelling abroad. Often since a fear has crossed my mind lest that book might turn up yet, and fall into the hands of some malicious person who would publish it. I know its appearance would cause me as much heart-burning as my youthful horse-trade, or the later rebuke for wearing uniform clothes.
The 3d infantry had selected camping grounds on the reservation at Fort Jessup, about midway between the Red River and the Sabine. Our orders required us to go into camp in the same neighborhood, and await further instructions. Those authorized to do so selected a place in the pine woods, between the old town of Natchitoches and Grand Ecore, about three miles from each, and on high ground back from the river. The place was given the name of Camp Salubrity, and proved entitled to it. The camp was on a high, sandy, pine ridge, with spring branches in the valley, in front and rear. The springs furnished an abundance of cool, pure water, and the ridge was above the flight of mosquitoes, which abound in that region in great multitudes and of great voracity. In the valley they swarmed in myriads, but never came to the summit of the ridge. The regiment occupied this camp six months before the first death occurred, and that was caused by an accident.
There was no intimation given that the removal of the 3d and 4th regiments of infantry to the western border of Louisiana was occasioned in any way by the prospective annexation of Texas, but it was generally understood that such was the case. Ostensibly we were intended to prevent filibustering into Texas, but really as a menace to Mexico in case she appeared to contemplate war. Generally the officers of the army were indifferent whether the annexation was consummated or not; but not so all of them. For myself, I was bitterly opposed to the measure, and to this day regard the war, which resulted, as one of the most unjust ever waged by a stronger against a weaker nation. It was an instance of a republic following the bad example of European monarchies, in not considering justice in their desire to acquire additional territory.
Texas was originally a state belonging to the republic of Mexico. It extended from the Sabine River on the east to the Rio Grande on the west, and from the Gulf of Mexico on the south and east to the territory of the United States and New Mexico—another Mexican state at that time—on the north and west. An empire in territory, it had but a very sparse population, until settled by Americans who had received authority from Mexico to colonize. These colonists paid very little attention to the supreme government, and introduced slavery into the state almost from the start, though the constitution of Mexico did not, nor does it now, sanction that institution. Soon they set up an independent government of their own, and war existed, between Texas and Mexico, in name from that time until 1836, when active hostilities very nearly ceased upon the capture of Santa Anna, the Mexican President. Before long, however, the same people—who with permission of Mexico had colonized Texas, and afterwards set up slavery there, and then seceded as soon as they felt strong enough to do so—offered themselves and the State to the United States, and in 1845 their offer was accepted. The occupation, separation and annexation were, from the inception of the movement to its final consummation, a conspiracy to acquire territory out of which slave states might be formed for the American Union.
Even if the annexation itself could be justified, the manner in which the subsequent war was forced upon Mexico cannot. The fact is, annexationists wanted more territory than they could possibly lay any claim to, as part of the new acquisition. Texas, as an independent State, never had exercised jurisdiction over the territory between the Nueces River and the Rio Grande. Mexico had never recognized the independence of Texas, and maintained that, even if independent, the State had no claim south of the Nueces. I am aware that a treaty, made by the Texans with Santa Anna while he was under duress, ceded all the territory between the Nueces and the Rio Grande—, but he was a prisoner of war when the treaty was made, and his life was in jeopardy. He knew, too, that he deserved execution at the hands of the Texans, if they should ever capture him. The Texans, if they had taken his life, would have only followed the example set by Santa Anna himself a few years before, when he executed the entire garrison of the Alamo and the villagers of Goliad.
In taking military possession of Texas after annexation, the army of occupation, under General Taylor, was directed to occupy the disputed territory. The army did not stop at the Nueces and offer to negotiate for a settlement of the boundary question, but went beyond, apparently in order to force Mexico to initiate war. It is to the credit of the American nation, however, that after conquering Mexico, and while practically holding the country in our possession, so that we could have retained the whole of it, or made any terms we chose, we paid a round sum for the additional territory taken; more than it was worth, or was likely to be, to Mexico. To us it was an empire and of incalculable value; but it might have been obtained by other means. The Southern rebellion was largely the outgrowth of the Mexican war. Nations, like individuals, are punished for their transgressions. We got our punishment in the most sanguinary and expensive war of modern times.
The 4th infantry went into camp at Salubrity in the month of May, 1844, with instructions, as I have said, to await further orders. At first, officers and men occupied ordinary tents. As the summer heat increased these were covered by sheds to break the rays of the sun. The summer was whiled away in social enjoyments among the officers, in visiting those stationed at, and near, Fort Jessup, twenty-five miles away, visiting the planters on the Red River, and the citizens of Natchitoches and Grand Ecore. There was much pleasant intercourse between the inhabitants and the officers of the army. I retain very agreeable recollections of my stay at Camp Salubrity, and of the acquaintances made there, and no doubt my feeling is shared by the few officers living who were there at the time. I can call to mind only two officers of the 4th infantry, besides myself, who were at Camp Salubrity with the regiment, who are now alive.
With a war in prospect, and belonging to a regiment that had an unusual number of officers detailed on special duty away from the regiment, my hopes of being ordered to West Point as instructor vanished. At the time of which I now write, officers in the quartermaster's, commissary's and adjutant—general's departments were appointed from the line of the army, and did not vacate their regimental commissions until their regimental and staff commissions were for the same grades. Generally lieutenants were appointed to captaincies to fill vacancies in the staff corps. If they should reach a captaincy in the line before they arrived at a majority in the staff, they would elect which commission they would retain. In the 4th infantry, in 1844, at least six line officers were on duty in the staff, and therefore permanently detached from the regiment. Under these circumstances I gave up everything like a special course of reading, and only read thereafter for my own amusement, and not very much for that, until the war was over. I kept a horse and rode, and staid out of doors most of the time by day, and entirely recovered from the cough which I had carried from West Point, and from all indications of consumption. I have often thought that my life was saved, and my health restored, by exercise and exposure, enforced by an administrative act, and a war, both of which I disapproved.
As summer wore away, and cool days and colder nights came upon us, the tents we were occupying ceased to afford comfortable quarters; and "further orders" not reaching us, we began to look about to remedy the hardship. Men were put to work getting out timber to build huts, and in a very short time all were comfortably housed—privates as well as officers. The outlay by the government in accomplishing this was nothing, or nearly nothing. The winter was spent more agreeably than the summer had been. There were occasional parties given by the planters along the "coast"—as the bottom lands on the Red River were called. The climate was delightful.
Near the close of the short session of Congress of 1844-5, the bill for the annexation of Texas to the United States was passed. It reached President Tyler on the 1st of March, 1845, and promptly received his approval. When the news reached us we began to look again for "further orders." They did not arrive promptly, and on the 1st of May following I asked and obtained a leave of absence for twenty days, for the purpose of visiting—St. Louis. The object of this visit has been before stated.
