Cabeza de Vaca was a Spanish conquistador that set out to find and claim new land; he took 5 barges on his expedition. On his journey across the ocean he was hit by many natural disasters. Four of his barges sank and his barge was the only one that had survived the conditions.
Even though Cabeza de Vaca and his crew survived, they were stranded on an island. They are starving and in need for resources so he sends a scout to go check out the area.
Cabeza de Vaca's scout was found by Indians and was taken back to the ship with the Indians. Cabeza de Vaca quickly made a trade with the Indians by giving them bells with the return of an arrow from each Indian in a declaration of friendship.
Cabeza tried leaving the island again but he failed; many of his crew members died in the attempt. They washed up on shore and the Indians wept with them in compassion for the members that passed.
Cabeza de Vaca's crew eventually got disease and spread it on to the Indians. The Indians were unhappy and were going to let the crew starve but Cabeza de Vaca negotiated a deal to where his crew would become medicine men for their people in order to live; the Indians were delighted with the deal.
