For the operation Butler was given three companies of Marines and some sailors from the USS "Connecticut", about 100 men. They encircled the fort and gradually closed in on it. Butler reached the fort from the southern side with the 15th Company and found a small opening in the wall. The Marines entered through the opening and engaged the "Cacos" in hand-to-hand combat.
