31st Infantry Regiment (United States) (Philippine Scouts) was a regiment of the Philippine Scouts organized under the United States Army for service in the Philippines from the early 20th century through World War II. Composed primarily of Filipino enlisted men and American officers, the regiment served in garrison duty, frontier policing, and major combat during the Japanese invasion and the Battle of Bataan. It suffered capture and internment following the surrender on Bataan and was later reconstituted in various forms during the postwar period.
The 31st Infantry Regiment traces its origin to the expansion of the Philippine Scouts after the Philippine–American War when the United States War Department sought professionalized indigenous forces for colonial defense. The regiment was organized under regulations from the United States Army and stationed at posts such as Fort William McKinley and Fort Stotsenburg in the Philippine Islands, integrating veteran noncommissioned officers from units like the 26th Cavalry Regiment (Philippine Scouts), the 43rd Infantry Regiment (Philippine Scouts), and the 45th Infantry Regiment (Philippine Scouts). Officers were assigned through United States Military Academy graduates, Infantry Branch (United States) personnel, and volunteers from the Regular Army, while recruits were drawn from regions such as Ilocos, Cebu, Leyte, and Mindanao. Organizational structure followed the US regimental model with headquarters, battalions, companies, and attached machine-gun elements influenced by doctrine from the United States Army War College and equipment issued by the Ordnance Department.
During the interwar years the 31st Infantry Regiment conducted garrison duty, counterinsurgency patrols, and civic action programs in coordination with the Philippine Constabulary, the Insular Government of the Philippine Islands, and American colonial administrators including governors-general such as William Cameron Forbes and Francis Burton Harrison. The regiment participated in joint exercises with units like the 26th Cavalry Regiment (Philippine Scouts) and trained under policies shaped by the National Defense Act (Philippines) and US strategic assessments from the General Staff (United States Army). It operated in strategic areas including the Central Luzon plains and the Cordillera Central, adapting to tropical disease control guided by the United States Public Health Service and medical doctrine from Walter Reed Army Institute of Research predecessors. The 31st also contributed men to civil infrastructure projects alongside the Philippine Bureau of Public Works and maintained ties with American military institutions such as the Presidio of San Francisco via rotation and officer exchange.
With rising tensions in the Pacific Theater (World War II), the 31st Infantry Regiment was mobilized for the defense of the Philippine Islands under the command structure of United States Army Forces in the Far East (USAFFE) led by Douglas MacArthur and subordinate commanders including Jonathan M. Wainwright IV and Edward P. King Jr.. Engaged in delaying actions and perimeter defense during the Japanese invasion of the Philippines (1941–42), the regiment fought in the Battle of Bataan alongside units such as the 45th Infantry Regiment (Philippine Scouts), the 192nd Tank Battalion (United States), the 31st Infantry Regiment (United States) (other US regiments), and elements of the Philippine Army. Under heavy artillery and aerial attacks by the Imperial Japanese Army and Imperial Japanese Navy Air Service, the 31st conducted rear-guard actions, reconnaissance, and counterattacks during the collapse of organized resistance. Supply shortages, tropical disease, and intense combat contributed to attrition culminating in the surrender of Bataan in April 1942.
Following capture, members of the 31st Infantry Regiment endured the Bataan Death March and subsequent imprisonment in camps run by the Empire of Japan, including transfer to locations such as Cabanatuan, Olongapo, and camps in Formosa and Japan. Prisoners faced starvation, forced labor on projects tied to the South China Sea, exposure to disease, and summary executions; some were transported aboard "hell ships" such as the Arisan Maru and Enoura Maru. A minority of the regiment evaded capture and later joined the Philippine resistance movement and guerrilla units under leaders like Ramon Magsaysay and Carlos Romulo, linking with Allied intelligence networks including Combined Operations and Office of Strategic Services. Survivors liberated in 1944–45 were repatriated via Leyte and Manila and later provided accounts used by inquiries into war crimes prosecuted by the Tokyo Trials and United States military tribunals.
After World War II, the Philippine Scouts and regiments like the 31st were largely disbanded as the Philippine Commonwealth moved toward independence under leaders such as Manuel Roxas and the new Republic of the Philippines. Veterans of the 31st Infantry received recognition from the United States Congress, veterans' organizations like the Veterans of Foreign Wars and American Legion, and military decorations including the Purple Heart and Distinguished Service Cross. The regiment's lineage and honors influenced successor units within the United States Army Philippine Department records and contributed to historical studies at institutions such as the National Archives and Records Administration and the United States Army Center of Military History. Memorialization appears at sites including the Bataan Memorial, Corregidor, and the Libingan ng mga Bayani, and in scholarship by historians like John W. Van Alstyne and Louis Morton.
The 31st Infantry Regiment's insignia, colors, and regimental traditions reflected the hybrid nature of the Philippine Scouts, combining elements consecrated by the United States Army Institute of Heraldry and local Philippine symbols. Regimental honors included campaign credit for Bataan and unit citations recognized by the Department of the Army. Traditions upheld by veterans encompassed commemorations on Araw ng Kagitingan (Day of Valor), ceremonies at Fort Santiago, and reunions sponsored by organizations such as the Philippine Scouts Heritage Society. The regiment's history remains cited in works on the Pacific War, Philippine military heritage, and US colonial military policy.
