Admiral Montojo had meanwhile transferred his flags to the Isla de Cuba; and the Baltimore, leaving the American line, made straight for his former flagship, which threw a torrent of shells toward the intrepid American. The Baltimore, however, notwithstanding that a few of these deadly missiles exploded on her deck, wounding eight of her crew, continued her course till within 2500 yards of her antagonist. Then from her decks she fired a broadside at the Spaniard. There was an ominous silence for a minute or two, and both Spaniards and Americans waited anxiously for the smoke to lift. Suddenly, all saw a sight that struck every man in both fleets with terror, for it seemed the probable fate of all. The Cristina shot into the air and then fell back upon the waves with a thunderous crash, while a thousand fragments of men and timbers--promiscuously mingled in awful confusion--were whirling through the air. Down into the waves she sank--that gallant man-of-war--the pride of the Spanish fleet--down into the deep blue sea. Upon the surface, amid tons of floating débris, a hundred sailors struggled for life; many sank to rise no more; some, however, succeeded in reaching one of the adjacent consorts. The Baltimore, aided by the Olympia and the Raleigh, now kept up a deadly fire on the Juan de Austria; which answered this terrible fusillade with intermittent volleys, that spoke well for the courage, but poorly for the aim, of her gunners. It was at this moment that the Raleigh sent a shell crashing through the other's centre, exploding her magazine; in an instant she seemed a crater of flame, and sank back like the Cristina, a total wreck. Her flying fragments also inflicted such damage upon the gunboat El Correo, which lay beside her, that she was completely disabled. The Petrel gave her a finishing shot, that closed her brief career. Another Spanish gunboat, the General Lezo, also set out to accomplish great things, but the Concord, with a few good shots, put a quietus upon her warlike ambition, and, like her sister ships, she too was soon a floating wreck. Meanwhile, the Boston was engaged in a duel with the Velasco. Captain Wildes, of the former, stood on the bridge of his ship vigorously fanning with a palm-leaf fan; for it was a hot morning and it was the captain's policy to keep cool. The Velasco responded to the Boston's broadsides but feebly. Then with a plunge she careened to one side and sank heavily, her crew having scarcely enough time to escape to the adjacent shore. The Castilla had already been set on fire and scuttled by her crew, to prevent her magazine from exploding.
