They, perceiving us at our first coming on land, supposed us to have been their enemies the bordering Spaniards; and having, by their forerunners, descried what number we were, and how feeble and weak, without armour or weapon, they suddenly, according to their accustomed manner when they encounter with any people in warlike sort, raised a terrible and huge cry, and so came running fiercely upon us, shooting off their arrows as thick as hail, unto whose mercy we were constrained to yield, not having amongst us any kind of armour, nor yet weapon, saving one Caliver and two old rusty swords, whereby to make any resistance or to save ourselves; which, when they perceived that we sought not any other than favour and mercy at their hands, and that we were not their enemies the Spaniards, they had compassion on us, and came and caused us all to sit down.
