San Quentin

      Located off the islands of Grande and Chiquita at the eastern entrance of Subic Bay in 6 to 18 meters of water this is a excellent dive site for everyone. Surface conditions can be a little rough at times but the diving is relatively calm with a occasional mild current. The wrecks have been underwater for over 100 years and nature has not left that much left. The majority of the San Quinten has collapsed upon it’s self. The boilers do however still stand high above the surrounding area and above the wreck. Coral and sponges have a firm footing on the wreck, which sits on a patch of sand. The hull and deck have created many holes and crevices, which are the home of fish, ells and lobsters.


This is also a great site for night dives. Due south of the boilers across about 10 meters of sand you will find the keel of one of the merchant ships. To the north of the wreck is a shallow reef about 5 to 10 meters deep. Alive with many types of fish, corals and sponges, this reef has a special treat not seen on any other site wreck within Subic. In 1999 the University of the Philippines in secret had a special project that introduced giant clams to Subic bay. One of these sites is this reef.


On the 25th of April,(1898) at 11 p.m., says Señor Montojo, I left the bay of Manila for Subic with a squadron composed of the cruisers Reina Cristina, Don Juan de Austria, Isla de Cuba, Isla de Luzon, dispatch boat Marques del Duero, and the wooden cruiser Castilla. This last could merely be considered as a floating battery incapable of maneuvering, on account of the bad condition of her hull. The following morning, being at Subic, I had a conference with Captain Del Rio, who, though he did not relieve my anxiety respecting the completion of the defensive works, assured me that they would soon be finished. In the meanwhile the cruiser Castilla, even on this short cruise, was making much water through the bearings of the propeller and the opening astern.

They worked day and night to stop these leaks with cement, finally making the vessel nearly water-tight, but absolutely impossible to use her engines. One the morning of the 27th I sailed with the vessels to cover the entrance to the port of Subic. The Castilla was taken to the northeast point of the island of Grande to defend the western entrance, since the eastern entrance had already been closed with the hulls of the San Quintin and two old merchant vessels which were sunk there.

With much disgust, I found that the guns which should have been mounted on that island were delayed a month and a half. This surprised me, as the shore batteries that the navy had installed (with very little difficulty) at the entrance of the bay of Manila, under the intelligent direction of colonel of naval artillery, Señor Garces, and Lieutenant Beneavente, were ready to fight twenty-four days after the commencement of the work. I was also no less disgusted that they confided in the efficacy of the few torpedoes which they had found feasible to put there. The entrance was not defended by torpedoes nor by the batteries of the island, so that the squadron would have had to bear the attack of the Americans with its own resources, in 40 meters of water and with little security.


Our vessels could not only be destroyed, but they could not save their crews. I still held a hope that the Americans would not go to Subic, and give us time for more preparations, but the following day I received from the Spanish consul at Hong Kong a telegram which said :A enemy’s squadron sailed at 2 p. m. from the bay of Mira and according to reliable accounts they sailed for Subic to destroy our squadron, and then will go to Manila This telegram demonstrated that the enemy knew where they could find my squadron and that the port of Subic had no defenses. The same day, the 28th of April, I convened a council of the captains, and all, with the exception of Del Rio, chief of the new arsenal, thought that the situation was insupportable and that we should go to the bay of Manila in order to accept there the battle under less unfavorable conditions.
