nt of the United States during the term filled by
President Pierce. Had Hamer filled that office his partiality for me
was such, there is but little doubt I should have been appointed to one
of the staff corps of the army--the Pay Department probably--and would
therefore now be preparing to retire. Neither of these speculations is
unreasonable, and they are mentioned to show how little men control
their own destiny.

Reinforcements having arrived, in the month of August the movement
commenced from Matamoras to Camargo, the head of navigation on the Rio
Grande. The line of the Rio Grande was all that was necessary to hold,
unless it was intended to invade Mexico from the North. In that case
the most natural route to take was the one which General Taylor
selected. It entered a pass in the Sierra Madre Mountains, at Monterey,
through which the main road runs to the City of Mexico. Monterey itself
was a good point to hold, even if the line of the Rio Grande covered all
the territory we desired to occupy at that time. It is built on a plain
two thousand feet above tide water, where the air is bracing and the
situation healthy.

On the 19th of August the army started for Monterey, leaving a small
garrison at Matamoras. The troops, with the exception of the artillery,
cavalry, and the brigade to which I belonged, were moved up the river to
Camargo on steamers. As there were but two or three of these, the boats
had to make a number of trips before the last of the troops were
up. Those who marched did so by the south side of the river.
Lieutenant-Colonel Garland, of the 4th infantry, was the brigade
commander, and on this occasion commanded the entire marching force.
One day out convinced him that marching by day in that latitude, in the
month of August, was not a beneficial sanitary measure, particularly for
Northern men. The order of marching was changed and night marches were
substituted with the best results.

When Camargo was reached, we found a city of tents outside the Mexican
hamlet. I was detailed to act as quartermaster and commissary to the
regiment. The teams that had proven abundantly sufficient to transport
all supplies from Corpus Christi to the Rio Grande over the level
prairies of Texas, were entirely inadequate to the needs of the
reinforced army in a mountainous country. To obviate the deficiency,
pack mules were hired, with Mexicans to pack and drive them. I had
charge of the few wagons allot
