Having defeated the Guaycurús, the governor pursued them. As one of the horsemen was following him, an Indian of the enemy seized hold of the mare he was riding by the neck, and pierced her through and through with three arrows he held in his hand; nor could they make him loose his hold of the animal before they had killed him.

If the governor had not been present at this fight the victory would have been doubtful.

These Indians are very tall, swift of foot, valiant and strong. They are Gentiles, having no fixed abode, and subsist by hunting and fishing. No nation had ever conquered them before the Spaniards, and their idea is, if anyone should vanquish them, to serve them as slaves. Their women are allowed the right of delivering a prisoner who has fallen into their hands, so that he shall neither be killed nor enslaved, and if he choose to remain among them, he is treated as one of their own people. These women have certainly more liberty than that bestowed on our women in Spain by Queen Isabella, our Sovereign Lady.
