At the time of which I now write we had no transportation and the country about Salt River was sparsely settled, so that it took some days to collect teams and drivers enough to move the camp and garrison equipage of a regiment nearly a thousand strong, together with a week's supply of provision and some ammunition. While preparations for the move were going on I felt quite comfortable; but when we got on the road and found every house deserted I was anything but easy. In the twenty- five miles we had to march we did not see a person, old or young, male or female, except two horsemen who were on a road that crossed ours. As soon as they saw us they decamped as fast as their horses could carry them. I kept my men in the ranks and forbade their entering any of the deserted houses or taking anything from them. We halted at night on the road and proceeded the next morning at an early hour. Harris had been encamped in a creek bottom for the sake of being near water. The hills on either side of the creek extend to a considerable height, possibly more than a hundred feet. As we approached the brow of the hill from which it was expected we could see Harris' camp, and possibly find his men ready formed to meet us, my heart kept getting higher and higher until it felt to me as though it was in my throat. I would have given anything then to have been back in Illinois, but I had not the moral courage to halt and consider what to do; I kept right on. When we reached a point from which the valley below was in full view I halted.
The place where Harris had been encamped a few days before was still there and the marks of a recent encampment were plainly visible, but the troops were gone. My heart resumed its place. It occurred to me at once that Harris had been as much afraid of me as I had been of him. This was a view of the question I had never taken before; but it was one I never forgot afterwards. From that event to the close of the war, I never experienced trepidation upon confronting an enemy, though I always felt more or less anxiety. I never forgot that he had as much reason to fear my forces as I had his. The lesson was valuable.
Inquiries at the village of Florida divulged the fact that Colonel Harris, learning of my intended movement, while my transportation was being collected took time by the forelock and left Florida before I had started from Salt River. He had increased the distance between us by forty miles. The next day I started back to my old camp at Salt River bridge. The citizens living on the line of our march had returned to their houses after we passed, and finding everything in good order, nothing carried away, they were at their front doors ready to greet us now. They had evidently been led to believe that the National troops carried death and devastation with them wherever they went.
In a short time after our return to Salt River bridge I was ordered with my regiment to the town of Mexico. General Pope was then commanding the district embracing all of the State of Missouri between the Mississippi and Missouri rivers, with his headquarters in the village of Mexico. I was assigned to the command of a sub-district embracing the troops in the immediate neighborhood, some three regiments of infantry and a section of artillery. There was one regiment encamped by the side of mine. I assumed command of the whole and the first night sent the commander of the other regiment the parole and countersign. Not wishing to be outdone in courtesy, he immediately sent me the countersign for his regiment for the night. When he was informed that the countersign sent to him was for use with his regiment as well as mine, it was difficult to make him understand that this was not an unwarranted interference of one colonel over another. No doubt he attributed it for the time to the presumption of a graduate of West Point over a volunteer pure and simple. But the question was soon settled and we had no further trouble.
My arrival in Mexico had been preceded by that of two or three regiments in which proper discipline had not been maintained, and the men had been in the habit of visiting houses without invitation and helping themselves to food and drink, or demanding them from the occupants. They carried their muskets while out of camp and made every man they found take the oath of allegiance to the government. I at once published orders prohibiting the soldiers from going into private houses unless invited by the inhabitants, and from appropriating private property to their own or to government uses. The people were no longer molested or made afraid. I received the most marked courtesy from the citizens of Mexico as long as I remained there.
Up to this time my regiment had not been carried in the school of the soldier beyond the company drill, except that it had received some training on the march from Springfield to the Illinois River. There was now a good opportunity of exercising it in the battalion drill. While I was at West Point the tactics used in the army had been Scott's and the musket the flint lock. I had never looked at a copy of tactics from the time of my graduation. My standing in that branch of studies had been near the foot of the class. In the Mexican war in the summer of 1846, I had been appointed regimental quartermaster and commissary and had not been at a battalion drill since. The arms had been changed since then and Hardee's tactics had been adopted. I got a copy of tactics and studied one lesson, intending to confine the exercise of the first day to the commands I had thus learned. By pursuing this course from day to day I thought I would soon get through the volume.
We were encamped just outside of town on the common, among scattering suburban houses with enclosed gardens, and when I got my regiment in line and rode to the front I soon saw that if I attempted to follow the lesson I had studied I would have to clear away some of the houses and garden fences to make room. I perceived at once, however, that Hardee's tactics--a mere translation from the French with Hardee's name attached--was nothing more than common sense and the progress of the age applied to Scott's system. The commands were abbreviated and the movement expedited. Under the old tactics almost every change in the order of march was preceded by a "halt," then came the change, and then the "forward march." With the new tactics all these changes could be made while in motion. I found no trouble in giving commands that would take my regiment where I wanted it to go and carry it around all obstacles. I do not believe that the officers of the regiment ever discovered that I had never studied the tactics that I used.
