What does Robinson discover about the ship that comes to the island and brings hostages to the beach?

After spending over twenty-eight years on his island, Robinson Crusoe finds that a ship has approached the island and anchored nearby. He immediately recognizes it to be an English ship, although he is suspicious as to its presence in that region. He knows that English ships do not come into these waters and believes that the ship might be carrying “thieves and murderers.”
Keeping his guard up, he and Friday continue to watch the sailors as they bring the longboat to shore. They see several of the sailors dragging three of the men onto the shore, threatening and mistreating the three men to the point that Friday believes that the sailors intend to eat the three men, just as his own people do to their captives.
After the three men plead for their lives, the sailors fall asleep after wandering on the shore, and Crusoe approaches the three hostages to find out more about their circumstances. One of the three men explains that he had been the captain of the English ship and that his crew had mutinied against him and then captured him, his first mate, and a passenger. Crusoe offers to help the men escape and to seek justice against these mutineers with the captain in exchange for passage to England when the ship is recovered.
