Passage: It took Clifford's men two weeks of struggle through mud and rain—often dangerously close to friendly mortar and artillery fire—to root the Japanese out of fighting positions on the way up Kilay Ridge. On 2 December Clifford's battalion finally cleared the heights overlooking the road, and 32nd Division units quickly took over. Clifford's outfit suffered 26 killed, 101 wounded and two missing, in contrast to 900 Japanese dead. For their arduous efforts against Kilay Ridge and adjacent areas, both flanking battalions received Presidential Unit Citations. Clifford and Spragins both received the Distinguished Service Cross for their actions. It was not until 14 December that the 32nd Division finally cleared the Breakneck–Kilay Ridge area, and linked up with the 1st Cavalry Division on 19 Dec., placing the most heavily defended portions of Highway 2 between Carigara Bay and the Ormoc Valley under X Corps control.Throughout this phase, American efforts had become increasingly hampered by logistical problems. Mountainous terrain and impassable roads forced Sixth Army transportation units to improvise resupply trains of Navy landing craft, tracked landing vehicles, airdrops, artillery tractors, trucks, even carabaos and hundreds of barefoot Filipino bearers. The 727th Amphibian Tractor Battalion made daily, often multiple, trips with ammunition and rations between Capoocan and Calubian. From Calubian, the 727th tractors would navigate the Naga River to Consuegra and then traverse overland to Agahang. On their return trip, they would evacuate the casualties. Not surprisingly, the complex scheduling slowed resupply as well as the pace of assaults, particularly in the mountains north and east of Ormoc Valley and subsequently in the ridgelines along Ormoc Bay.
