Battery Smith can be found by following the trail which leads off the tour tram-turning pad near Battery Grubbs. Follow the trail a few hundred yards and you'll come to a tunnel entrance on your left. When exploring the tunnel, be aware that it's on more than one level, and watch for the the trapdoors in the floor, which lead down to lower levels.
Hearn hearn75.jpg (32629 bytes) 1 12-in BCLR A-59 29,000  
Battery Hearn was formerly known as Smith No. 2 but the name was changed pre-war.  Hearn is a big favourite with the tourists, who mill around it like moths to a flame and take their obligatory "been there, done that" photographs.   Captain Herman Hauck put a link of chain in the recoil cylinder of one of Crockett's operational 12-inch guns. If it were ever fired by the Japanese, it would have self-destructed immediately. Hearn is always on the tour list, as is Crockett, because they're easily reached. The truth of the matter is that neither of them played any significant role in the hostilities, due to their positions facing squarely towards the South China Sea and the naval assaults that never came. A 1936 Corps of Engineers map shows Btty. Hearn was then named Btty. Smith No. 2.  What was  at the bottom of this curious piece of history? The answer can now be found at  Battery Smith
Cheney chnyvue.JPG (91549 bytes) 2 12-in DC D-59 17,000 cheney1.JPG (91395 bytes)
Battery Cheney complemented Btty Wheeler as large above ground batteries, sited to face the sea lanes approaching Manila Bay.   Built into the rocky cliffs and steep ravines, particularly on Topside, were batteries containing a formal array of eighteen twelve inch and ten inch coastal rifles and twenty-four twelve-inch mortars. On an average day in the early spring of 1942 about 11,500 persons were crowded onto Corregidor's 1735 acres, yet the coast artillery batteries and the beach defences had less than half the number of defenders needed. This was because over half of the persons on the island were not trained combatants. The bulk of the population of the fortress was more like that of a sprawling Philippine version of the Pentagon.

Named after Capt. Woodridge Geary, a casualty in the 1899 US-Philippine war, was commenced in 1907 and completed 1911 at a cost of $145,198. On 2 May 1942, Battery Geary takes a direct hit from a 240mm shell. The tail of the island lies under a cloud of smoke and dust.  One of the mortars still has a "fire in the hole".

Way BttyWay.JPG (105603 bytes) 4 12-in 4-M,’88 Mortars E-60 14,000 way2.jpg (120512 bytes)
Battery Geary and  Battery Way were armed with 12-inch mortars.  Geary had eight, and Way had four. By 1941, these weapons were decidedly old.  In the annals of bravery, one can't go past Batteries Geary and Way. Because  the high trajectories of their mortars were able  to put shells on the Bataan peninsular, the Japanese artillery made special effort to bring counterbattery fire upon them. Battery Way kept on firing until the day of the surrender, when its last mortar became so hot, it "froze" the breech. For the history of the unit which manned Btty Way, go to Btty "E" 60th Coast Artillery (AA). For a portrait of their CO jump to Eric Sprengle's Major William "Wild Bill" Massello. On 6 May 2002, a memorial was dedicated to Massello in a small ceremony held at Battery Way.  The keynote speaker was Tom Murphy, who has written "Wild Bill's Memorial."  Eric Sprengle's Major William "Wild Bill" Massello.For a Floor Plan, go to Floor Plan Battery Way
Grubbs grubbs.JPG (73511 bytes) 2 10-in DC C-91 13,500  
Unfortunately for the purposes of posterity, President Clinton visited Corregidor not too long ago and Battery Grubbs suffered from a coat of paint and the installation of handrails. There are some things that really should be left to appear as if they are rusting in peace. There's no room for "prettying-up" the wreckage of history with cans of jungle-green paint.
R.J. 43   2 8-in DC   24,000 named after the Road Junction where it was located
Ramsey   3 6-in DC   14,000  
Battery Ramsay - suffered a direct hit, and there is very little of it which has survived. There is a large hole in the ground where it once was, and the guns, together with their concrete emplacements, are up-ended nearby as if some giant hand had smashed them aside. The battery was not manned when it was hit. Al McGrew, one of our regular contributors, manned a machine gun sited immediately in front of  the No. 1 gun, and has contributed a plan of the battery.

- Walking the trails of Corregidor and hiking it's hills can bring you to gems in the jungle such as Battery Morrison. You'll find it rusting in peace, and you'll want to leave it that way. If you have the time, walk the road which is behind Middleside Barracks until you get to Battery James. Then walk back along the road until you see a walking track going up the hill to your left. Follow it through and you'll arrive at Btty. Morrison.

Monja was at the Wheeler Point end of the South Shore Road.  The road between Searchlight Point and Wheeler Point has been cut by bombardment and landslides, and Monja is no longer accessable by road. Due to its isolated location at the base of the steep cliffs, it was the scene of protracted  heavy action between Japanese Marines and members  of the 503rd PRCT.  It's also been the scene of some more recent attempts by treasure hunters to obtain access to the tunnels and magazines.  There's nothing there, except adventure. During the siege, it was manned by Filipinos from G-92nd CA under command of an American,  Lt. Ulanowitz.

Reyson Battery Reyson appears to be the result of inaccurate scholarship. It is mentioned in a few books, notably some which were published in the Philippines, however there is no record of it ever having existed on Corregidor. The extended stories of the "Search for Battery Reyson" and the "Suicide Cliff" over which no Japanese Defender ever committed suicide can be found at Reyson.

Drum rm7.jpg (15585 bytes) Refer Drum Page for data Fort Drum is not on Corregidor, but is one of the chain of forts stretched across the mouth of Manila Bay, like a string of pearls.   The forts were, from the west, named Mills, Hughes, Drum and Frank

503rd RCT Veteran Corregidoros Don Abbott writes:


"Let me expound a bit on my classification of the guns on Corregidor.  I  would class them as BIG GUNS, 155 GUNS, SMALL GUNS AND AAA.

Start with the "Big Guns"  you have Morrison (2x6inch disappearing), Way (4x12 inch Mortars),  Grubbs (2x10inch disappearing), Smith 1 1x12inch Barbette), Hearn (formerly known as Smith 2)(1x12inch Barbette), Cheney (2x12inch disappearing), Wheeler (2x12inch   disappearing), Geary (8x12inch Mortars), Crockett (2x12inch disappearing) and Ramsay (3x6inch disappearing).  RJ 43 (1x8inch Railroad Gun) would have been a big gun1 but it was emplaced shortly before the end and never entered into the fight.

Then there are the 155 mm GPF's (they are about 6 inches).  They were emplaced in batteries, Sunset, Monja, Rock Point, Levagood, Kysor, Stockade, Ordnance Point and Hamilton.   Actually, these are problem to place because, for example Lt (later LG) Wright took two 155's from Battery Sunset and formed a "roving battery" to try and get away from Japanese counter fire.  Some of the time he set up in the parade ground and fired over the 59th CA barracks.

The small guns were the 3-inch pedestal mounted guns designed to protect the  mine fields.  These batteries, manned by  the Philippine Army were at Hanna, Cushing, James and Maxwell Keyes. The 60th CA manned several Anti-Aircraft batteries firing 3-inch AA mounted guns at Boston, Chicago and Denver.

Searchlights, although not guns, were important installations.  There were several of these.  I have not got into the 50 caliber MG's like the one Al McGrew manned.  You asked about Battery Monja. Monja is spanish for Nun.   There is a Monja Island a few miles west of Corridor.   You can locate Battery Monja on Wheeler point at the west end of the South Shore Road.  There was one 155 mm gun placed in a concrete embrasure.  There was, also, one 155 mm gun in the cut at the end of the road.  This battery was manned by Filipinos from G-92nd CA under command of an American Lt. Ulanowitz.  I have some good drawings of Battery Monja and will send some of them to you when I find them.(Don found the drawings and a detailed engineering view of Monja and its magazine are now available - Ed.) "

Don Abbott


The attack and reduction of the larger fortifications such as Batteries Geary, Hearn, Smith and Wheeler presented more formidable obstacles. The underground portions of these concrete and steel reinforced blockhouses were virtually impervious to artillery and naval gunfire. In addition, their underground interiors were honeycombed with tunnels, storerooms baffles behind the entrances and exits, and built with many exits, some overrun with vines and brush or concealed behind rubble. The enemy within these fortifications had to be forced out into the open or somehow killed within them.

This Battery History, like others on the website,  appears here because of a long line of men, many whose names will never be known. These men, at the risk of their lives, composed the the original documents whilst in a Japanese Prison Camp and hid them for the duration.  Not every battery history has survived the war, and their loss is part of the tragic story of being in the hands of an enemy who had no regard for human life.  

At the end of the line of these men who have preserved these histories, are George Munson and Al McGrew (himself a POW) who made them available to me so that I could publish them for the first time on the internet,  and bring them into the public domain.
