From Calansayan, there is a road constructed by the Japs going to Sorosoro Hill. This road terminates at the group of houses H-1 shown in the sketch. These houses are occupied by the Japanese forces. From these houses, there are several trails going up the hill and to the mouths of tunnesl A, B, C, D, and E.

50 meters south of these houses are two tunnels, A and B, shown in the sketch. The distance between tunnels A and B is around 10 meters. These tunnels are dug at the foot of the hill passing straight thru the other side.

Around 20 meters north of these houses is a dugout marked 0 where ammunition is kept. This dugout is covered by big trees.

At the summit of the hill (the most elevated part of the hill marked S on the sketch), the Japs dug a hole downward connecting the ends of the tunnels C, D, and E in level with the foot of the hill.

The Japs stay in all these tunnels especially during the daytime when there are planes around.

Southwest of Point S, going down the hill, there is a small depression wherein the barracks have been constructed. These barracks are made of bamboos and cogon roofing. There is a dugout under these barracks where the ammunition and good supplies are kept.

Right at the foot of the hill marked M in the sketch are machine guns, .50 caliber. Fronting this machine gun emplacements are five (5) lines of barbed wire entanglements starting from the group of houses marked H-1 and terminating at the side of the river shown in the sketch. These barbed wire entanglements are not visible from the air because they are placed under big trees. Trucks, ammunition and food supplies are kept under these big trees along the barbed wire entanglements.

From the railroad crossing shown in the sketch going east before reaching the hill are several tank traps strayed among the banana trees. These are shown by rectangles shown in the sketch. These tank traps cover around 1km. distance.

The strength of Sorosoro Hill is changeable, ranging from 500 to 1000 strong. Sorosoro and Banay-banay forces interchange. The Sorosoro Hill forces are under the command of Capt. Tanisi and 2nd Lt. Fukoka.
