Location
Lat 14° 22' 0N Long 120° 37' 0E  Island at the entrance to Manila Bay near Corregidor.

History
This island was developed by the US Army as a coastal defense fortification prewar. There are many untouched relics still remaining on the island, including two massive 14" coastal guns and four 12" mortars, all still emplaced in their pre-WW II positions. Today it is abandoned and off limits to visitors generally.

Fort Hughes
Located on Caballo Island.

Tony Feredo adds:
"The fort's magazines and other concrete structures of the batteries are there. All old wooden building already gone. Wharf is still original and a big chunk already got destroyed via a typhoon in 2002. No memorials except for a few markers where bones of Japanese soldiers were re-buried years after the war."

Battery Craighill
There are two pits, each armed with 2-inch Mortar M1912 on on 12-inch Mortar Carriage M1896M3. These had 50% longer barrels than the ones on Corregidor.

Tony Feredo adds:
"They also fired experimental rounds on 12-inch shells to be used as AA rounds. The problem was that it did not produce the proper muzzle velocity to arm the fuse at a certain height which will cause the shell to detonate."

Crew members from the gunboat USS Mindanao (PR-8) joined the crew of this gun on April 10, 1942 after the fall of Bataan. After firing only 26 practice rounds, the Army instructors qualified the sailors as artillery qualified. By the end of the battle, they had fired 500 shells at targets at Bataan and Cavite. Continually bombed by the Japanese, the gunners suffered only one casualty.
