Exploring this Massive Sea Fortress in the Philippines

800meters off the coast of Maragondon in Cavite was one of the defense forts at the entrance to Manila Bay established by the United States.
The long, narrow island is surrounded by sheer cliffs over 30 meters. The whole island and fort has an area of 18 hectares with the highest elevation at 56 meters.
The entire island was designated as Fort Frank, in honor of Brigadier General Royal T. Frank, as part of the Harbor Defenses of Manila and Subic Bays built by the Philippine Department of the US Army in the early 1900s.

At dahil nagkaproblema ang iilang videoshots namin (yun pa naman ang mga kuha na may mahahalagang info) kaya dito ko nalang ilalagay sa comment section ang mga impormasyong nais nyong malaman tungkol dito sa Isla. Fort Frank (Carabao Island) was one of the defense forts at the entrance to Manila Bay established by the United States. The entire island was designated as Fort Frank, in honor of Brigadier General Royal T. Frank, as part of the Harbor Defenses of Manila and Subic Bays built by the Philippine Department of the US Army in the early 1900s. The fort's design included little protection against air and high-angle artillery attacks except camouflage. Also, most of its heavy ammunition was armor-piercing, intended for use against battleships, rather than the high explosive type that would be more useful against enemy troops and artillery. Fort Frank was heavily engaged in the Japanese invasion of the Philippines. On 31 January 1942, the fort's mortar battery bombarded mainland positions in the Pico de Loro Hills where the Japanese were placing artillery. The 75 mm guns were also able to engage mainland targets. The Japanese began bombarding Fort Drum and Fort Frank on 6 February 1942. Fort Frank was vulnerable in another way: its normal water supply was from a dam's reservoir on the Japanese-held mainland. On 16 February the Japanese discovered this and removed part of the pipeline near the dam. Although the fort also had a distillation plant to provide fresh water, this consumed fuel that was also needed for the gun batteries' generators that powered the ammunition hoists. The fort's commander ordered the distillation plant started, but also directed a 15-man team to attempt to restore the pipeline on the 19th. They successfully engaged a Japanese patrol but could not get to the pipeline. Eventually, another party repaired the pipeline on 9 March. On 20 March 1942, thirty-four soldiers were killed by Japanese artillery when a round ricocheted into a tunnel at Battery Crofton. Fort Frank was surrendered, along with all other US forces in the Philippines, on 6 May 1942, after destruction procedures were executed on its guns to prevent their use by the enemy. During their occupation, the Japanese were reportedly able to repair the 14 in (356 mm) gun of Battery Crofton and add three 100 mm (3.94 in) guns. In April 1945, during the American liberation of the Philippines, Fort Frank was heavily bombarded with 1,000 lb (450 kg) bombs and napalm (among other ordnance) in preparation for recapture. On 16 April 1945 the 1st Battalion, 151st Infantry Regiment and Co. C, 113th Engineer Battalion landed on Fort Frank to find that the Japanese had successfully evacuated the island.
