    When the war started, this 10 elevation was in effect, which limited the range of this armament to 10,200 yards.  Three months after hostilities began, the gun mounts were again altered to permit 12° of elevation.  This increased the range from 10,200 yards to 11,400 yards.

    The above mentioned artillery comprised the entire armament of Fort Drum up to the beginning of the war.  A diagram showing the fields of fire reveal a wide area of dead space in the stern of the fort.  Only one battery, the rear 14-inch guns, would traverse this field of fire to the rear in Manila Bay.  The fact that the cagemast was directly between the turret and stern caused this battery to have severe limitation due to dead space.  Even though the cagemast had not existed, the top deck coupled with the height site created a dead space.  This meant that enemy surface craft, approaching Fort Drum from the rear in Manila Bay, could not be brought under fire from the guns of Fort Drum.

     

    When the Japanese Army gained control of Manila, and the Cavite shoreline, this weakness became a problem.  The fact that the enemy had seized a number of large harbor boats and countless other power craft and barges at Manila, heightened the acuteness of the problem.  Action was taken to remedy this situation.

     

    A Model 1906 3-inch seacoast gun, with pedestal mount, was shipped to Fort Drum.  A concrete base on which to bolt the pedestal was poured and the gun was mounted 12 January 1942, and designated as Battery Hoyle.  This emplacement was on top edge of the stern.

     

    The following day, 13 January, at 1430, an enemy vessel was observed approaching Fort Drum from Niac.  As it drew near, it turned out to be a double-deck vessel of the inter-island type.  That the enemy was well aware of the old weakness was evident as she bore down upon the fort, keeping the cage mast between her and the 14-inch turret.  Apparently she had not discovered our latest addition.  Major General Moore called Fort Drum and inquired if the newly emplaced 3-inch gun could be fired.  On receiving an affirmative answer, he ordered the Fort Commander to open fire with the 3-inch gun.  Remember that the concrete was less than 24 hours old and that the range drum was without graduation.  The piece had neither been bore-sighted nor checked for assurance level.

     

    A five-man crew of old artillerymen were assembled.  As the target grew nearer, observers noted that the decks were lined with enemy troops in uniform and civilians, apparently making an inspection trip to the area in the rear of Drum.

     

    Range was called vocally from the depression position finder in the cage mast.  Fire was opened at 9,000 yards.  The first round was off in deflection.  The Japanese surprise was evident by the mass confusion on her decks.  She began a fast turn which exposed her stern.  The seventh and eighth rounds were near misses throwing geysers of water on the target.  The ninth was short as the enemy was pulling out of range.  Never again did the enemy attempt to approach Fort Drum from the rear.  This was the first battery of seacoast artillery to open fire on the enemy in World War II.

     

    (3)   Other Armament.  For antiaircraft artillery there were two 3-inch mobile AA guns jacked down on spider mounts on the deck.  Fire control was by director and stereoscopic height finder.  Combination protection for both defense and low-flying planes was provided for by four 50-caliber, water-cooled, AA machine guns with improvised mounts and two 50-caliber air-cooled machine guns donated by the Air Corps.  Thirteen caliber 30, M1 water-cooled machine guns with Infantry mounts served for beach defense.  This was augmented by four Thompson sub machine guns secured from the 4th U.S. Marines through the detachment of marines on Fort Drum.  A quantity of Springfield rifles, with some long barrels, pump shotguns completed the defenses.

     

    Illumination was by searchlight.  Number twelve seacoast searchlight was located on the top of the eighty foot cage mast.  The light was put out of action the first day Fort Drum was taken under fire.  Number eleven seacoast searchlight was located on the southeast side of Fort Hughes.  This light was under the direct command of Fort Drum.  Its' mission was to provide illumination of that part of Manila Bay from Cavite to Rostinga Point, just southwest of Ternate.  The purpose of this was to prevent enemy attacks by water from the rear of Corregidor and the fortified islands.  This light was in action until the surrender.
