It was on the 12th of October, 1524, that Cortez commenced his march almost due south from the city of Mexico. His force consisted, when he started from Mexico, of about one hundred Spanish horsemen and fifty infantry, together with about three thousand Mexican soldiers. Apprehending that Guatemozin and the cacique of Tacuba, from their strong influence over the natives, might excite disturbance during his absence, he took them as captives with him. Several Catholic priests were taken to conduct the services of religion, and to convert the heathen tribes. The imperial retinue, for Cortez now moved with the pomp of an emperor, was conducted on the grandest scale the time and the occasion would admit. A large herd of swine followed the army a day's journey in the rear. Most of the food, however, was to be collected by the way. By the aid of a rude map and Indian guides, Cortez designed to direct his steps across the neck of the broad peninsula of Yucatan to the head of the Bay of Honduras. For many days their path conducted along a low and marshy country intersected by innumerable streams. Some they were able to ford; over others their ingenious architects would speedily throw a bridge. Occasionally they would arrive upon the banks of a stream so wide and deep that many days would be employed in rearing a structure over which they could pass. Cortez, in his letter to Charles V., enumerating the difficulties encountered, states that in a distance of one hundred miles he found it necessary to construct no less than fifty bridges. The amiable Marina accompanied Cortez on this expedition, since her services were very essential as interpreter. But Cortez now, having buried his lawful wife, and probably looking forward to some more illustrious Spanish alliance which might strengthen his influence at court, regarded Marina as an embarrassment. He therefore secured her marriage with a Castilian knight, Don Juan Xamarillo. A handsome estate was assigned to the newly-married couple in the native province of Marina, through which the expedition passed on its way to Honduras. We hear of Marina no more. Her son, Don Martin Cortez, aided by the patronage of his powerful father, became one of the most prominent of the grandees of his native land. He filled many posts of opulence and honor. At last he was suspected of treason against the home government, and was shamefully put to the torture in the Mexican capital.
