Scarcely was the felucca under way when the sentinel who had been left in the battery, to keep watch upon the movements of the pirates ashore, summoned us to our posts; and upon our arrival there we at once saw that our preparations had not been completed a moment too soon.  For, as we topped the hill that obstructed the view of the Cove from the seaward side of the islet, we saw the whole male population of the settlement, numbering about one hundred and forty, marching down to the beach, with the evident intention of embarking in their boats and pulling off to attack us.  With the aid of my telescope I could distinctly distinguish the figure of Fernandez, who was assuming the direction of operations; and I could not but admire the strictness of the discipline which he appeared to exercise over his followers, for the fellows seemed amenable to his briefest order.  They possessed exactly twenty boats in all, ranging in size from a craft capable of accommodating forty men down to the little Norwegian dinghy in which I had made my escape, and it was evident that every man of the party had been previously told off to some particular boat; for upon their arrival at the beach the hitherto compact body at once dissolved into twenty separate detachments, each of which made its way, in a perfectly orderly manner, to a particular boat; the whole flotilla being launched and manned at Fernandez' word of command.  This done, the boats were turned round with their bows pointing straight for the islet, and--again at the word of command--the oars, as one, dropped into the water and the expedition advanced to the attack in a long straight line.
