Captain O’Shea climbed the rampart and lashed an American ensign to a spar thrust into the sand. The bright flag was neither half-masted nor reversed as a signal of distress. The breeze flaunted it as a defiance, a message from men who had forfeited its protection, who cheered the sight of it for sentimental reasons which they could not have clearly explained. The governments of the United States and Spain were at peace. This was not an affair between the two Powers. It was a little private war, a singular incident. And yet it was somehow fitting, after all, that these outlaws should prefer to see the stars and stripes waving over their heads. Presently Colonel Calvo planted beside this ensign the tricolor of the Cuban revolutionaries, with the lone star. It was done with a certain amount of ceremony which commanded respect and admiration. It signified that he, too, speaking for his men, was ready to make the last stand, to accept the decree of fortune. Johnny Kent grasped his hand and apologized. The cruiser moved cautiously nearer the key, taking frequent soundings. The wreck of the _Fearless_ had been discovered and must have been identified, for the cruiser cleared for action, and the bugles trilled on her decks. The huge, four-sided mound of sand heaped upon the back of the key evidently puzzled the officers. After a long delay, the vessel let go an anchor a thousand yards from the beach and spitefully hurled several shells into the shattered hulk of the _Fearless_. Then a pair of eight-inch turret-guns were trained at Captain O’Shea’s thick walls of sand. A string of small flags fluttered from the cruiser’s signal-yard. O’Shea comprehended the message without consulting the international code-book. “She invites us to surrender,” he explained, “which I decline to do at present. Let her shoot away. Maybe she will tire of it and leave us.” No white flag was displayed on the rampart, and the cruiser lost her temper. A projectile passed over the key with a noise like a derailed freight-train. Others followed until the sand was spurting in yellow geysers. Such shells as struck the earthwork burrowed deep holes without causing appreciable damage. The Spanish commander soon perceived that this impromptu fortification was costly to bombard. His gunners were merely burying shells in a large heap of sand, and his government had not been lavish in filling his magazines. A mortar battery was needed to discommode this insane crew of pirates. And undoubtedly, if a landing-party should be disembarked on the open beach, these rascals of Captain O’Shea would fight like devils. The cruiser had been ordered to fetch them back to Havana alive and they would be formally executed in the Cabañas fortress as a warning to other hardy seafarers in the filibustering trade. These men had not only fired on the Spanish flag, but they had also blown it out of water.
