The Battle of Serranilla occurred in September 1719 when the pirate captain Edward Kenway destroyed the British naval fort of Serranilla, off the coast of Nicaragua. Kenway, in command of the brig Jackdaw, used his ship's maneuverability to make several passes around the fort, bombarding its defenses each time. While the fort proved to be a very difficult obstacle, the pirates ultimately succeeded in destroying its outer defenses, allowing for Kenway and his crew to assault the weakened defenses. Kenway succeeded in slaying the officers in charge of the fort's defense, and he later headed to the war room and killed the fort's commander, Robert Killigrew. The fort became a pirate stronghold during the last few years of the Golden Age of Piracy, and Kenway would use Serranilla as a base for his operations against the Spanish Navy off the coast of New Spain.
