The primary conflict in Robert Louis Stevenson's Treasure Island is a simple one: Who will get to the buried treasure first? We never fully understand why Billy Bones never attempts to return for the loot himself, but it could have been because he was wary of being followed by his former mates. After Jim Hawkins and his mom find the map, Squire Trelawney agrees to finance the voyage and cut Jim in on the treasure. After the squire's loose lips spread the word around Bristol about the voyage for treasure, Long John Silver becomes the main adversary for the squire's men. Silver and the majority of the crew mutiny and, after several battles with the loyal crew, they head for the treasure. Unbeknownst to them all, Ben Gunn has been marooned there, and he has already found the treasure. Eventually, Ben teams up with Squire Trelawney's men; Silver's men turn on him; the squire's group returns to the ship with Gunn and the treasure--and Silver; and the remaining pirates are left behind. Gunn receives a small share; Silver steals a small amount before disappearing; and Trelawney, Dr. Livesey, and Jim return to England--rich men all.
There are three types of conflicts in the novel that are all important. They are man vs. man, man vs. nature, and man vs. himself. These are all conflicts that Hawkins has. An example of man vs. man is Hawkins against Billy Bones. Man vs. nature is seen when Hawkins must navigate the strong currents of the island's narrow harbors. Hawkins also has some internal conflicts where he struggles with the choices he has to make. For example, Hawkins decides to abandon his crew. I'm not sure that one of these conflicts is more important than the others since they take place throughout the book and provide the challenges that Hawkins must face.
