G-1 COMMAND POST
 

Text and Photos by John Moffitt

 

In his serialization of Col. Paul Bunker's diary, there are numerous references to meetings taking place at G-1 throughout the siege.  On Corregidor maps there is a structure labeled "G1" with the official designation of "Gun Group Command Post #1." It is located midway between Batteries Smith and Hearn. After taking some GPS waypoints for Mapmaster at Battery Grubbs, I decided to head over there and check it out.

This area always seemed like a no-mans land to me as from the side of the roads, all you see is thick vegetation in there. Not a fun place to travel at all. However, like many places on the island, it is deceiving. The sides of the roads and trails are quite open, so plants grow thick. Once you get past them into the canopy, the plants fade away and walking is actually not too bad.

To make it even easier, I walked on the old trail to the eastern entrance of the Battery Smith Tunnel. Here I set the GPS to show me the straight line direction to Battery Hearn. From the tunnel entrance to the Battery Hearn gun, it is 239 metres so not far at all.

The terrain is slightly hilly with a downward slope towards the right. I saw small hills, craters and traces of old roads. In only a few minutes I could see what looked like a black tunnel entrance in a small hill slightly off to one side. (Photo A.) This turned out to be a battle damage hole in the side of a soil, grass and tree covered structure.

On looking inside the hole I saw lots of similarities with C1, so I knew I had found G1. I could see the hexagonal platform for the range and direction finding equipment however the roof has partially collapsed closing the narrow front viewing area.

I will try to explain what I mean by the “narrow front viewing area”. Photo B in this series is an image of the upper section of the C1 Command Post near Battery Wheeler. G1 probably looked like this in better days. Notice the narrow viewing area which is on the front and both sides. Metal bars at the corners support the reinforced concrete roof above the lower walls. These bars are positioned on an angle so that they present the least profile as possible that would block the view of the range and direction finding equipment located inside. 

In G1, the roof is partially collapsed towards the front. (Photo D.)Both front corners including the metal bars are missing, so the main supports for the roof are gone. To me it looks like this was caused by battle damage.

(Above) Gun Group Command Posts such as G1 and their individual battery control equivalents all have hexagon shaped concrete pedestals where range finding and azimuth equipment would be mounted. (Below) U.S. Army photo, via the CDSG Website, showing a range finder on the left and azimuth scope on the right.
 

I was taking photos when I finally realized “Hey, where is the outside door?” I had entered through the hole in front the side wall. C1 has a doorway and steps up to ground level at the rear of the telephone booths but this Command Post did not. Past the telephone booths I got a surprise. At the rear wall on the left hand side was a set of steps down to a second level. I love exploring. :D

I headed down the stairs. As usual, the lizards were not happy to have a guest. The largest ones are about 8 inches to a foot long but I don’t think they are dangerous. They just scurry along the upper walls or ceilings ahead of you. If you get close to them such as pass through a doorway that they are near, they start dropping from the ceiling and run away on the floor.

Two years ago in the pitch blackness, I had a small one land on the back of my neck before he jumped off. I damn near had a heart attack. Occupational hazards I guess.

At the bottom of the stairs you turn left into a square room. It is totally empty except for concrete fragments and some miscellaneous junk on the floor. The ceiling looks like the scrappers spent considerable time here. Another thing I noticed is all the bullet holes in one corner. I wonder what happened here to provoke this many years ago.

As you enter this room, you see another doorway to the right. When I take photos in tunnels or zero light rooms, I turn off my flashlight so as not to get a white spot in the photos. At this time I noticed a faint glow coming from the second doorway so I knew there was an outside opening not far too away.

Finishing my photos in the room, I went through the doorway to the left. Within six feet or so it turns to the right and you see a long set of steps up to the surface.

This Command Post had no vertical air vent up to the surface but perhaps it was not needed. The upper level was open at the front and the lower level had the staircase at the rear.

I don’t think this place gets many visitors. In a way, I'm glad. I cleared the entrance a bit more, took some photos and continued on to Battery Hearn.

B.  the upper section of the C1 Command Post near Battery Wheeler. G1 probably looked like this in better days. Notice the narrow viewing area which is on the front and both sides. Metal bars at the corners support the reinforced concrete roof above the lower walls. These bars are positioned on an angle so that they present the least profile as possible that would block the view of the range and direction finding equipment located inside.

 

C.  C1 showing one of the angled metal bars and the hexagon shaped range and direction finding pedestal on the inside floor. 

 

 D. In G1, the roof is partially collapsed towards the front. Both front corners, including the metal bars, are missing so the main supports for the roof are gone. To me it looks like this was caused by battle damage.

 

E. Looking towards the collapsed front. The front left corner is severely damaged and to the right, the whole corner and a section of the wall is missing. This is the larger hole from which I entered the room.

 

 F.  Taken from the doorway at the rear of the main room. Note the hexagon shaped pedestal on the floor

 

G.  To the rear of the main room is a doorway going to the communications area which had three ‘telephone booths’ on each side.

 

H. Telephone booths. Cable and power conduits can be seen to the rear of the right side wall.

 

 

I. View from the communications area out into the main room.

 

 

 

J.  View of the rear wall with telephone booths on each side. Steps head down to the left.

 

K. Looking down the steps. A green painted square area at the bottom leads to a rectangular room to the left.

 

L. Looking back up the stairs.

 

M. As you enter this room, you see another doorway to the right. When I take photos in tunnels or zero light rooms, I turn off my flashlight so as not to get a white spot in the photos. At this time I noticed a faint glow coming from the second doorway so I knew there was an outside opening not far too away.

N. The doorway to the right comes from the upper level.

 

O. Looking up the steps. They are steeper than this view indicates.

 P. Looking down the steps.

 

Q. Command Post outside entrance.

 

R. View of Battery Hearn with the magazine at the rear. Few tour guides know that a major battle occurred around this magazine, "Calhoun's Hill" in 1945.  It's like a tour guide driving you through the town of Sainte Mère Église and not showing you the church.
