But although the brig was moored well in, so that the boats passing to and fro might have but a short distance to travel, we in the felucca were alongside and had secured undisputed possession of the vessel before the boats with their armed crews had traversed half the distance between her and the shore; seeing which, the occupants paused and drew together, as if to confer and to await further developments.  Of this brief pause we promptly availed ourselves by getting the brig under way and working her and the felucca out toward the entrance, when, much to our astonishment, the boats with one accord turned round and pulled back to the beach.  This unexpected action on their part was a great relief to me, for I had fully expected that they would make a concerted effort to recapture the brig, or the felucca, or both, by boarding, in which case we should have had our hands full, and must almost certainly have lost a few men.  But probably they believed the felucca to be armed with cannon, and fully expected to be received with liberal doses of grape and canister, which would fully account for their sudden and unexpected display of prudence.  Be that as it may, we were allowed to work both craft out to sea without molestation; when, having hurriedly overhauled our prize and found that she was amply provisioned for a much longer voyage than that to Port Royal, I put her in command of my second midshipman, with a prize-crew of ten men, and, giving him instructions to report to the Admiral without delay, dispatched him forthwith.  Then, transferring myself and the remainder of my following back to the felucca, we re-entered the Cove and came to an anchor outside of but close to the islet that masked the entrance, and in such a position that the little craft could be warped right in alongside a bit of cliff that dropped sheer down into the water.  We had scarcely done this when a deep, hollow _boom_, echoing and re-echoing along the face of the cliff that enclosed the Cove, told us that the party which had been dispatched to breach the road up the face of the cliff, and so cut off the retreat of the pirates toward the interior of the island, had accomplished its task.
