Answer:
First, the Spaniards came across a group of hostile Indians who gave them food and shelter, but they overstayed their welcome. Next, they were stranded in a swamp, and killed their horses every 3 days for food, and they used the rest of the horse to make a raft. Their raft then fell apart killing many of the men at sea, and stranding the survivors. Some died from drinking sea water, and others died other unfortunate deaths. The natives on that island gave them food, but they were disgusted by the Spaniards because they ate the men who died. Many of the crew were taken in by the Natives as slaves, and 5 years later, de Vaca, and 3 of his men escaped from slavery, and had to walk all the way back to New Spain. 400 men left on that expedition, 4 came back.
