For extraordinary heroism and eminent and conspicuous conduct in battle at the junction of the Cadacan and Sohoton Rivers, Samar, Philippine Islands, 17 November 1901. In command of the columns upon their uniting ashore in the Sohoton Region, Col. Porter (then Capt.) made a surprise attack on the fortified cliffs and completely routed the enemy, killing 30 and capturing and destroying the powder magazine, 40 lantacas (guns), rice, food and cuartels. Due to his courage, intelligence, discrimination, and zeal, he successfully led his men up the cliffs by means of bamboo ladders to a height of 200 feet. The cliffs were of soft stone of volcanic origin, in the nature of pumice, and were honeycombed with caves. Tons of rocks were suspended in platforms held in position by vine cables (known as bejuco) in readiness to be precipitated upon people below. After driving the insurgents from their position, which was almost impregnable, being covered with numerous trails lined with poison spears, pits, etc., Col. Porter led his men across the river, scaled the cliffs on the opposite side, and destroyed the camps there. He and the men under his command overcame incredible difficulties and dangers in destroying positions which, according to reports from old prisoners, had taken three years to perfect, were held as a final rallying post, and had never before been penetrated by white troops. Col. Porter also rendered distinguished public service in the presence of the enemy at Quinapundan River, Samar, Philippine Islands, 26 October 1901.
