How did Jim become a prisoner of the squire and dr livesey?

Jim became a prisoner of Squire Trelawney and Dr. Livesey after being captured by the mutinous crew of the Hispaniola during their quest for treasure on Treasure Island. Initially part of the expedition, Jim's knowledge of the pirates' plans led to his being hunted by them, forcing him to seek refuge with the squire and the doctor. Eventually, the conflict between the loyal crew and the mutineers escalated, leading to Jim's temporary captivity as he navigated the dangers of the island and the treachery among the crew.
