The Tepeacans received their enemy on their borders. A bloody battle followed, in which the Spanish horse were somewhat embarrassed by the tall maize that covered part of the plain. They were successful in the end, and the Tepeacans, after holding their ground like good warriors, were at length routed with great slaughter. A second engagement, which took place a few days after, was followed by like decisive results; and the victorious Spaniards with their allies, marching straightway on the city of Tepeaca, entered it in triumph.[250] No further resistance was attempted by the enemy, and the whole province, to avoid further calamities, eagerly tendered its submission. Cortés, however, inflicted the meditated chastisement on the places implicated in the massacre. The inhabitants were branded with a hot iron as slaves, and, after the royal fifth had been reserved, were distributed between his own men and the allies.[251] The Spaniards were familiar with the system of _repartimientos_ established in the islands; but this was the first example of slavery in New Spain.{*} It was justified, in the opinion of the general and his military casuists, by the aggravated offences of the party. The sentence, however, was not countenanced by the crown,[252] which, as the colonial legislation abundantly shows, was ever at issue with the craving and mercenary spirit of the colonist. {*} [It may have been the first instance of natives being reduced to slavery by the Spaniards, but female slaves at least had been given to them on several previous occasions by the Mexican chiefs. The present case has also no connection with the system of _repartimientos_, by which, after the conquest was effected, the soil and its inhabitants were divided among the new possessors. In the case of the Tepeacans, no attempt was made to enslave the adult males, whose services were not needed, and who would have brought only embarrassment to their captors. See Bernal Diaz, Hist. de la Conquista, cap. 135.--K.]] Satisfied with this display of his vengeance, Cortés now established his headquarters at Tepeaca, which, situated in a cultivated country, afforded easy means for maintaining an army, while its position on the Mexican frontier made it a good _point d’appui_ for future operations. The Aztec government, since it had learned the issue of its negotiations at Tlascala, had been diligent in fortifying its frontier in that quarter. The garrisons usually maintained there were strengthened, and large bodies of men were marched in the same direction, with orders to occupy the strong positions on the borders. The conduct of these troops was in their usual style of arrogance and extortion, and greatly disgusted the inhabitants of the country.
