Sinking the Spanish Fleet: Isla and Manila
The Boston, Concord and Petrel were ordered to enter the bay and destroy the ships there. The Petrel being of very light draught was able to penetrate behind the breakwater up to the gunboats. The Spaniards on board made haste to surrender, and their ships were then scuttled and fired. The only ship left was a transport belonging to the coast survey, and she was taken possession of by our forces. At 40 minutes past 12 o'clock, the Spanish flag had been hauled down from Cavite and the white flag of surrender was flying. The Olympia stood off towards Manila, leaving the other vessels to take care of the wounded on shore.
In this battle the Spanish lost the following vessels: Reina Cristina, Castilla, Don Antonio de Ulloa, sunk; Don Juan de Austria, Isla de Luzon, Isla de Cuba, General Lezo, Marquis del Duero, El Correo, Velasco and Isla de Mindanao, burned; the Manila and several tugs and launches captured. There were 1,000 Spaniards killed in the engagement and more than 600 wounded, among the latter Admiral Montojo and his son, a lieutenant, both slightly. The wounded were removed to the arsenal in Cavite, where they were attended by the American surgeons, who gave their skill, science, and labor to succor the unfortunate. Yet while this work of humanity was in progress the Archbishop of Manila was issuing a pastoral letter to his flock in which he called upon all Christians in the island to defend the faith against heretics who designed to erect an insuperable barrier to salvation, intending to enslave the people and forbid the sacraments of baptism, matrimony, and burial, and the consolation of absolution. He declared that if the Americans were allowed to possess the islands, altars would be desecrated and the churches changed into Protestant chapels. Instead of there being pure morality, as then existed, examples of vice only would be inculcated. He closed by appointing May 17 as a day of rejoicing over the renewed consecration of the islands to "the Sacred Heart of Jesus."
Commodore Dewey sent a message to Governor-General Augusti in Manila proposing to be permitted to use the submarine cable to Hong-Kong for the purpose of communicating his reports to the government at Washington. Augusti refused the permission and Commodore Dewey cut the cable, thus rendering impossible all communication with the world except by mail, by way of Hong-Kong, three days' sail distant. He then anchored before Manila to await reinforcements and orders, the revolutionists under General Aguinaldo cutting off all supplies from the landside, and investing the city in effective siege.
