Note 27 — Chapter XII · The Mountain Barrier: Part One

Breakneck Ridge, over which Highway 2 corkscrewed its way between Pinamopoan and Limon for about 7,200 yards, was actually a hill mass with many spurs branching off from an irregularly shaped crest line toward the shores of Carigara Bay to the north and the Leyte River valley to the south. Shoulder-high cogon grass was thick on the low ground, and the pockets between the hills were heavily forested. The valleys were deep, with precipitous sides. The 1st Division had heavily fortified the area, taking advantage of the innumerable thickly wooded pockets that served as natural forts. The Japanese had also built an elaborate system of trenches and other defensive positions and had honeycombed the area with spider holes. Many of the latter were on reverse slopes some distance below the crests and were protected from direct fire. In front of each spider hole the enemy had cut fire lanes through the cogon grass, which was left so short that even a crawling soldier would be exposed to fire. The constant rainfall made the hills slippery and treacherous, and, more important, provided a protective curtain in the day and covered movements of the enemy at night.27
