Who won the battle in the stockade?

This is actually in chapter 21. Jim is assigned to load the muskets. Before the men even know it, a small group of pirates swarm the stockade fence, while others open fire from the woods. In the ensuing battle, the fight goes back and forth quickly before the battle is finally won. In the end, Jim and his men kill three pirates, three of the four who are storming the stockade, and the fourth pirate retreats as a coward.

May be that is chapter 21. Because I read it in book. Thank you so much
