At the end of the third day's fighting, all attacks of the Spaniards having been repulsed, Lieutenant-Colonel Huntington determined to take the offensive himself. About six miles southeast of the camp, at a place called Cuzco, there was a well from which the Spanish troops were said to obtain all their drinking-water, and a heliograph signal-station by means of which they maintained communication with Caimanera. On the morning of June 14 Captain Elliott, with two companies of marines and about fifty Cuban volunteers, was sent to attack this place, drive the Spaniards away, and destroy the well and signal-station. The expeditionary force engaged the enemy, five hundred strong, about eleven o'clock in the morning, and fought with them until three in the afternoon, driving them from their position and inflicting upon them a loss of sixty men killed and one hundred and fifty wounded. Then, after capturing the heliograph outfit, burning the station, and filling up the well, the heroic little detachment returned, exhausted but triumphant, to its camp, with a loss of only two men killed, six wounded, and twenty or thirty overcome by heat.
On the fourth day of the long struggle for the possession of Guantanamo Bay, the Spaniards virtually gave up the contest and abandoned the field. A few guerrillas still remained in the chaparral, firing occasionally at long range either into the camp or at the vessels of the fleet; but, finally, even this desultory, long-range target practice ceased, and the last of the enemy fled, either to the fort at Caimanera or to Guantanamo city, leaving the plucky marines in undisputed control of the whole eastern coast of the lower bay. Our total loss in the series of engagements was only six men killed and twelve or fifteen wounded; but among the killed was the lamented Dr. Gibbs, acting assistant surgeon, United States navy, who was shot at one o'clock on the night of the 11th.
After the four days of fighting were over, Captain McCalla, with the _Marblehead_, the auxiliary cruiser _St. Louis_, and the battle-ship _Texas_, steamed up the bay to the little village of Caimanera, demolished the fort there with a few well-directed shots, and drove the garrison back into the woods. In the course of this expedition the _Marblehead_ and the _Texas_ ran into a number of submarine contact mines, or fouled them with their screws; but, fortunately, none of them exploded. The firing-pins had become so incrusted with barnacles and other marine growths during their long immersion that the force of the blow when the ships struck them did not drive them in far enough to explode the charges. When we reached Guantanamo in the _State of Texas_, Captain McCalla's boats and launches had thoroughly explored and dragged the lower bay, and had taken out safely no less than thirteen contact mines, each containing about one hundred pounds of guncotton. The upper bay was still in the possession of the Spaniards; but its control was not a matter of any particular importance. What Admiral Sampson wanted was a safe and sheltered coaling-and repairing-station for the vessels of his fleet, and this he obtained when his war-ships and marines, after four days of almost incessant fighting, drove the Spanish troops from the whole eastern coast of the lower bay.
