fresh water, and the length
of the marches had to be regulated by the distance between water
supplies. Besides the streams, there were occasional pools, filled
during the rainy season, some probably made by the traders, who
travelled constantly between Corpus Christi and the Rio Grande, and some
by the buffalo. There was not at that time a single habitation,
cultivated field, or herd of domestic animals, between Corpus Christi
and Matamoras. It was necessary, therefore, to have a wagon train
sufficiently large to transport the camp and garrison equipage,
officers' baggage, rations for the army, and part rations of grain for
the artillery horses and all the animals taken from the north, where
they had been accustomed to having their forage furnished them. The
army was but indifferently supplied with transportation. Wagons and
harness could easily be supplied from the north but mules and horses
could not so readily be brought. The American traders and Mexican
smugglers came to the relief. Contracts were made for mules at from
eight to eleven dollars each. The smugglers furnished the animals, and
took their pay in goods of the description before mentioned. I doubt
whether the Mexicans received in value from the traders five dollars per
head for the animals they furnished, and still more, whether they paid
anything but their own time in procuring them. Such is trade; such is
war. The government paid in hard cash to the contractor the stipulated
price.
Between the Rio Grande and the Nueces there was at that time a large
band of wild horses feeding; as numerous, probably, as the band of
buffalo roaming further north was before its rapid extermination
commenced. The Mexicans used to capture these in large numbers and
bring them into the American settlements and sell them. A picked animal
could be purchased at from eight to twelve dollars, but taken at
wholesale, they could be bought for thirty-six dollars a dozen. Some of
these were purchased for the army, and answered a most useful purpose.
The horses were generally very strong, formed much like the Norman
horse, and with very heavy manes and tails. A number of officers
supplied themselves with these, and they generally rendered as useful
service as the northern animal in fact they were much better when
grazing was the only means of supplying forage.
There was no need for haste, and some months were consumed in the
necessary preparations for a move. In the
