Though counting more fighting vessels, the Spanish fleet was inferior to the American squadron in size and armament. The Spanish vessels mounted 116 guns, the American 135. But the Spanish fleet was protected by land batteries and forts armed with modern guns. The Spaniards were, therefore, much superior to the Americans in force and armament. At ten minutes past five the battle began, the Spaniards opening fire from ships and forts, at a distance of more than four miles. Two great mines were exploded in the path of the Olympia, but too far away to cause damage. At twenty-three minutes past five Dewey said to Captain Gridley: "You may fire when ready." Almost instantly an eight-inch gun roared out American defiance. As with one voice the blue-jackets of the squadron gave forth the American war-cry, "Remember the Maine!" and the battle was on. The Castilla lay moored head and stern under the protection of the guns, and surrounded by barges, which made it impossible to strike her below the water-line. The Reina Cristina, Admiral Montejo's flag-ship, and the other vessels of his fleet moved out to the battle protected by the forts and batteries. The Olympia in the lead, followed by the other vessels of the American squadron, headed straight for the centre of the Spanish line; then changing course, ran parallel to the Spanish line at a distance of four thousand yards. After passing the Spanish position the American squadron turned and again passed the Spanish line, decreasing the distance. The Spaniards were in strong position and fighting with consummate courage, but it soon became apparent that nothing could withstand the effects of American gunnery. Still, the Spaniards, knowing the exact distance of our vessels, were doing some damage. Early in the battle a shot struck and passed clean through the Baltimore, and another disabled a six-inch gun and exploded a box of ammunition, wounding eight men but killing no one. The Olympia was struck by a shell which, exploding outside, did little damage, and the signal halyards were cut out of the flag-officer's hands. The lines were immediately replaced by a blue-jacket. The Boston was struck by three shells, one starting a fire in a stateroom and another in the hammock-netting, while a third passed through the foremast near Captain Wildes. The squadron passed four times before the enemy, slightly decreasing the distance on each run, and on the fifth, believing that the depth of water was greater than he had supposed, Dewey took the Olympia closer, until on this last run he was within two thousand yards of the enemy. The Spaniards were suffering terribly and fought with courage and desperation. Admiral Montejo on the Reina Cristina sallied forth alone and made straight for the Olympia at full speed, but the concentrated fire of the whole American squadron drove him back to the protection of the breakwater, and as the flag-ship sped away, a shell from the Olympia struck her, passed through her
