During the night of 11-12 December, organizations defending the waterfront and beaches – the 7th AAA (AW) Battalion, elements of the Amphibious Tractor Battalion, and the Tank Destroyer and Cannon Company weapons of the 307th Infantry [Regt. of the 77th ID] – observed several enemy vessels moving into the bay, apparently with the intention of landing at Ormoc and on the beaches northwest of the town. The first vessel to be seen was a fifty-man barge approaching the Ormoc pier. By the time it came within range, all units had been alerted and the guns which bristled along the shoreline were tracking the unsuspecting craft. Fire was withheld until it was fifty yards from the pier. Then the silent night was shattered by the point-blank roar of 40 mm guns, .50 caliber machine guns, self-propelled howitzers and guns, and light and heavy machine guns, tracers from all of which converged on the barge. The first round of 40 mm fire was a direct hit and the barge became an orange ball of flame. Some Japanese stood on the gunwales and screamed "Don't shoot", apparently in the belief that their forces still occupied the town. They were smothered by fire from all sides which literally blew the barge out of the water.
The light from the burning boat, augmented by 60 mm illuminating shells, disclosed another Japanese landing vessel of the approximate size and type of an LST which, under cover of darkness, had beached northwest of Ormoc and was unloading troops and heavy equipment.
Self-propelled howitzers and guns of the 307th Infantry, which were emplaced along the beach within 1,000 yards [914 m] of the ship, opened fire while artillery forward observers of the 902d Field Artillery Battalion, who were with the 307th, directed artillery fire on the landing point and inland. Excitement ran high as a terrific volume of fire was poured into the enemy ship. A gunner on an M-10 tank destroyer was heard shouting above the din: "Throw up another flare so I can hit the son-of-a-bitch again." The Japanese skipper attempted to retract his ship but had not withdrawn over fifty yards when it burst into flames and sank.
There were indications that another vessel had beached still farther to the west. The artillery shelled the area and at dawn, a crippled ship was observed slowly making its escape far across the bay to the east. The shelling continued and, before it got out of range, its speed had been further reduced, its hull pierced, and clouds of black smoke were pouring from it. Planes later located and sank this vessel.
