The transports used were built for carrying freight and possessed but limited accommodations for passengers, and the climate added to the discomfort of all.
The transports with troops were assembled in the harbor of Anton Lizardo, some sixteen miles south of Vera Cruz, as they arrived, and there awaited the remainder of the fleet, bringing artillery, ammunition and supplies of all kinds from the North.

With the fleet there was a little steam propeller dispatch-boat--the first vessel of the kind I had ever seen, and probably the first of its kind ever seen by any one then with the army.

At that day ocean steamers were rare, and what there were were sidewheelers.

This little vessel, going through the fleet so fast, so noiselessly and with its propeller under water out of view, attracted a great deal of attention.

I recollect that Lieutenant Sidney Smith, of the 4th infantry, by whom I happened to be standing on the deck of a vessel when this propeller was passing, exclaimed, "Why, the thing looks as if it was propelled by the force of circumstances." Finally on the 7th of March, 1847, the little army of ten or twelve thousand men, given Scott to invade a country with a population of seven or eight millions, a mountainous country affording the greatest possible natural advantages for defence, was all assembled and ready to commence the perilous task of landing from vessels lying in the open sea.
The debarkation took place inside of the little island of Sacrificios, some three miles south of Vera Cruz.
