The adelantado incurred great expenses in the purchase of arms, ammunition, horses, and provisions; and, selling an estate, which yielded him two thousand ducats of rent, he fitted out four vessels at his own expense, and embarked in them four hundred Spaniards, under an agreement for a certain share of the advantages of the expedition.

In the year 1527 (the month is not known) the armament sailed from Seville, and, touching at the islands for supplies, it was remarked, as a circumstance of bad omen, that the adelantado had not on board two priests, which, under a general provision, every captain, officer, or subject who had license to discover and people islands or terra firma within the limits of the King of Spain, was bound to carry with him.

The fleet stopped at the island of Cozumel, where the adelantado had great difficulty in communicating with the Indians from want of an interpreter. Taking on board one of them as a guide, the fleet crossed over to the continent, and came to anchor off the coast. All the Spaniards went on shore, and, as the first act, with the solemnities usual in the new conquests, took formal possession of the country in the name of the king. Gonzalo Nieto planted the royal standard, and cried out, in a loud voice, "España! España! viva España!"

Leaving the sailors on board to take care of the vessel, the Spaniards landed their arms, ammunition, horses, and provisions, and, remaining here a few days to rest, from the excessive heat some became sick. The Indians knew that the Spaniards had established themselves in New Spain, and were determined to resist this invasion with all their strength; but, for the moment, they avoided any hostile demonstrations.

As yet the adelantado had only touched along the coast, and knew nothing of the interior. Experiencing great difficulty from the want of an interpreter, he commenced his march along the coast under the guidance of the Indian from Cozumel. The country was well peopled, and, without committing any violence upon the inhabitants, or suffering any injury from them, the Spaniards proceeded from town to town until they arrived at Conil. At this place, the Indians being apparently friendly, the Spaniards were thrown off their guard; and on one occasion, an Indian, who came to pay a visit, snatched a hanger from a little negro slave, and attempted to kill the adelantado. The latter drew his sword to defend himself, but the soldiers rushed forward and killed the Indian on the spot.

The adelantado now determined to march from Conil to the province of Choaca, and from this time they began to experience the dreadful hardships they were doomed to suffer in subduing Yucatan. There were no roads; the country was stony, and overgrown with thick woods. Fatigued with the difficulties of their march, the heat, and want of water, they arrived at Choaca, and found it deserted: the inhabitants had gone to join other Indians who were gathering for war. No one appeared to whom they could give notice of their pacific intentions, and the tidings that an Indian had been killed had gone before them.

Setting out again, still under the guidance of the Cozumel Indian, they reached a town named Aké. Here they found themselves confronted by a great multitude of Indians, who had lain in ambush, concealed in the woods.

These Indians were armed with quivers of arrows, sticks burned at the ends, lances pointed with sharp flints, and two-handed swords of very hard wood. They had flutes, and large sea-shells for trumpets, and turtle-shells which they struck with deers' horns. Their bodies were naked, except around the loins, and stained all over with earth of different colours, and they wore stone rings in their ears and noses.

The Spaniards were astonished at seeing such strange figures, and the noise that they made with the turtle-shells and horns, accompanied by a shout of voices, seemed to make the hills quake. The adelantado encouraged the Spaniards by relating his experience of war with the Indians, and a fearful battle commenced, which lasted all that day. Night came to put an end to the slaughter, but the Indians remained on the ground. The Spaniards had time to rest and bind up their wounds, but kept watch all night, with the dismal prospect of being destroyed on the next day.

At daylight the battle began again, and continued fiercely till midday, when the Indians began to give way. The Spaniards, encouraged by hope of victory, pressed them till they turned and fled, hiding themselves in the woods; but, ignorant of the ground, and worn out with constant fighting, the victors could only make themselves masters of the field. In this battle more than twelve hundred Indians were killed.
