Background of Philippines Involvement in the Korean War
One of the first United Nations members to answer the call to deploy troops and would go on to make meaningful battlefield contributions to the war effort in Korea was the Philippines. The Philippine government deployed one regimental combat team to fight in the Korean War that became known as the Philippine Expeditionary Force to Korea (PEFTOK). The PEFTOK soldiers arrived in Korea on September 19, 1950 at the port city of Pusan shortly after MacArthur’s successful Incheon Landing Operation that turned the tide of the Korean War.

During the nearly five years PEFTOK was deployed to Korea they participated in a number of heavy combat operations and established themselves a solid reputation as tough, tenacious fighters in the hills of Korea. Much of the tactical skills the Filipino soldiers used in Korea to great effect was honed during their own struggle against tyranny when the Japanese invaded the Philippines and Filipino guerrillas took to the hills to launch attacks against the Japanese. The Filipino military’s guerrilla warfare skills only improved when the military was called on to fight its own communist insurrection occurring in the highlands of the Philippines against the Hukbalahap which were guerrilla fighters aligned with the Philippine Communist Party.

“As Poor As We Are…”
This communist insurgency in the Philippines was the deciding factor for the Filipino President Elpidio Quirino to deploy forces to Korea. President Quirino feared that if Korea fell to the North Koreans then the global communist movement would then be encouraged to aid the Hukbalahap guerrillas fighting to overthrow the national government of the Philippines. President Quirino decided the Philippines had to make a stand against global communist movement and Korea was going to be that place. Here is how President Quirino opened his address to the Filipino soldiers about to deploy to Korea:

“Poor as we are, this country is making a great sacrifice in sending you there, but every peso invested in you is a sound investment for the perpetuation of our liberty and freedom.”

And poor they were because the Filipino government was nearly bankrupt at the time of this deployment due to the destruction of World War II as well as the continuing counterinsurgency struggle against the communist guerrillas in the highlands. Despite this the government was committed to deploying troops to Korea.

The Deployment of the 10th BCT
The military unit that heard this speech before they deployed was the 10th Battalion Combat Team (BCT). The Philippine military rotated combat teams to Korea every year with the 10th BCT being the first unit deployed to the peninsula which subsequently saw the heaviest combat of all the PEFTOK units sent to Korea. The 10th BCT was deployed with three infantry companies, a motorized reconnaissance company that was equipped with light M24 Chaffee tanks, a armored company with no tanks, and its own internal artillery battalion. The Filipinos were promised Sherman tanks from the US, but never received them to field the armored company with. In total the regiment was assigned approximately 1,400 men. An American trained tank commander, Lieutenant Colonel Mariano Azurin was chosen to lead this first PEFTOK unit into a war that would have great ramifications for his country if it was not won.

The 10th BCT was without a doubt a well equipped unit, but the UN command foundly them unprepared for combat in Korea and the unit spent it first weeks in Korea conducting pre-combat training in the city of Miryang. In October 1950, the 10th BCT received their first combat mission and was sent to the village Waegwan, which is the modern day home to the US military installation Camp Carroll. At Waegwan the 10th BCT’s reputation of being hardened anti-communist guerrilla fighters was put to the test. Throughout the hills in this area the Filipino soldiers worked with the US 25th Infantry Division to root out and destroy the remaining communists hiding in the hillsides.

Hunting Communist Guerrillas in the Hills of Korea
Before the Korean War South Korean communist guerrillas reinforced with North Korean infiltrators had tried to overthrow the ROK government and during the Korean War they were responsible for a number of attacks against the rear areas of American forces deployed to Korea. It was estimated that 35,000 communist guerrillas were operating in South Korea’s countryside and ironically enough it was up to a US trained tank commander LTC Azurin to help do something about it. The 10th BCT launched continuous small five man patrols during the day and at night to intercept the guerrillas trying to launch ambushes against UN supply lines in their area. The teams were small enough to avoid detection and sneak up and ambush the small guerrilla cells operating in the hills.

It was during this anti-guerrilla operation the PEFTOK would experience their first casualty with Private Alipio Ceciliano losing his life in defense of the Republic of Korea. However, the operation around Waegwon was a success with the 10th BCT killing large numbers of guerrillas in the hills and keeping the UN supply lines to Seoul open. The UN military leadership would turn to the Lieutenant Colonel Azurin again to lead another anti-guerrilla movement further north.

In late October LTC Azurin received orders that his men were going to be shipped north to the city of Kaesong to root out guerrillas harassing UN supply lines between Kaesong and Pyongyang. UN forces had moved across the 38th parallel and into North Korea to destroy the last remnants of the North Korean army and needed secure supply lines to support the offensive. LTC Azurin and his men would cross the 38th parallel themselves on October 31, 1950. The Filipinos were transported north by truck to conduct their operations in conjunction with the 65th Infantry which was an infantry regiment from Puerto Rico commanded by Colonel William Harris. The Filipinos were assigned to the 65th Regiment because of the mistaken belief that Filipinos spoke Spanish like the Puerto Ricans. Despite initial communication problems the two units’ leadership spoke enough English to coordinate operations between each other.

It was during this operation to secure the UN supply lines between Kaesong and Pyongyang that the Filipino battalion fought their first battle against a non-guerrilla unit. A battalion of North Korean soldiers ambushed the 10th BCT near the North Korean city of Muidong, but the hardened Filipino soldiers quickly counterattacked and killed 50 of the North Korean soldiers while only losing one Filipino soldier. Lieutenant Colonel Azurin continued his small team patrol tactics in this region to intercept guerrillas operating in the hills. Amazingly one of these small five man patrols was able to capture 77 North Korean soldiers that surrendered to them.

Relieving Colonel Azurin
It was during their anti-guerrilla campaign in North Korea that the bitter Korean winter hit the 10th BCT. The Filipino soldiers in the 10th BCT had never even seen snow before much less the extremely cold temperatures they found themselves in and were not properly equipped to deal with the cold. The 10th BCT was promised that they would receive cold weather gear from the American 24th ID regiment they found themselves working with in North Korea, but none arrived. Colonel Azurin fought bitterly with the American leadership to provide the clothing.

The 10th BCT would eventually receive their cold weather gear, but not before many Filipino soldiers received cold weather injuries and Colonel Azurin was relieved of his command at the request of the request of Colonel William Harris who accused Azurin of being, “much of a protester and not a doer”. The fight over the cold weather gear was the tipping point to remove Azurin because Colonel Harris had also fought bitterly with Azurin over dividing the 10th BCT from one whole battalion to five separate companies to conduct separate guerrilla operations in five different North Korean towns. Azurin wanted to keep the battalion together so each company could support each other and he could better command and control them. All indications are that Colonel Azurin was a good man trying to do his best for his soldiers, but as fate would have it, it ended up being a good thing for the 10th BCT to have Azurin relieved. The man who hand picked by Colonel Harris to replace Lieutenant Colonel Mariano Azurin would go on to become a great leader and a legendary hero of the Philippine military during the Korean War. This man was Lieutenant Colonel Dionisio Ojeda.
