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.
