Twice, that I remember, small trains were sent from Corpus Christi, with cavalry escorts, to San Antonio and Austin, with paymasters and funds to pay off small detachments of troops stationed at those places.

General Taylor encouraged officers to accompany these expeditions.

I accompanied one of them in December, 1845.

The distance from Corpus Christi to San Antonio was then computed at one hundred and fifty miles.
Now that roads exist it is probably less.

From San Antonio to Austin we computed the distance at one hundred and ten miles, and from the latter place back to Corpus Christi at over two hundred miles.
