It was now the 19th of February, and the galleon was not to leave port till the 14th of March, or, according to the old style followed by Anson, the 3d of March. The interval was employed in scrubbing the ships' bottoms, in bringing them into the most advantageous trim, and in regulating the orders, signals, and positions to be observed when the famous ship should appear in sight. The positions held were as follows: The squadron was stationed forty miles from shore,--an offing quite sufficient to escape observation: it consisted of the Centurion, the Gloucester, and three armed prizes: these were arranged in a circular line, and each ship was nine miles distant from the next, the two vessels at the extremes being, therefore, thirty-six miles apart. As the galleon could be easily discerned twenty miles outside of either extremity, the whole sweep of the squadron was seventy-five miles, the various vessels composing it being so connected by signals as to be readily informed of what was seen in any part of the line. The Centurion and the Gloucester were alone intended to come to close quarters, or, indeed, to engage in the action at all: they were therefore strengthened by accessions from the others. The calls of hunger and all other duties were neglected on the 3d of March: all eyes were strained in the direction of Acapulco, and voices continually exclaimed that they saw one of the cutters returning with a signal. To their extreme vexation and dismay, both that day and the next passed without bringing news of the galleon. A fortnight went by; and Anson at last came to the melancholy conclusion that his presence upon the coast had been discovered, and that an embargo had been laid upon the object of all their hopes. He afterwards discovered that his presence was suspected, but not known, but that the wary Spaniards had frustrated his schemes by detaining the galleon till the succeeding year. With a heavy heart, the admiral gave orders for the departure of the fleet from the American coast, in prosecution of the plans drawn up previous to his leaving England. He sailed early in May with the Centurion and Gloucester only, having scuttled and destroyed his three prizes on the enemy's coast. A terrible attack of scurvy soon reduced both vessels to half their working force, and a storm of unusual violence completely disabled the Gloucester. She held out, however, till the middle of August, when her stores, her prize-money, and her sick were with great difficulty removed to the Centurion, which was herself in a crazy and well-nigh desperate condition. The Gloucester was set on fire, lest her wreck might fall into the hands of the Spaniards: she continued burning through the night, firing her guns successively as the flames reached them: the magazine exploded at daylight.
