General Alfredo M. Santos (July 13, 1905 – February 7, 1990) was Chief of Staff of the Armed Forces of the Philippines in 1962 to 1965, making him the first four - star general of the Philippines' armed forces.

Engineer turned soldier, General Alfredo M. Santos is one of the most notable "Freedom Fighters" of the Philippines with a heroic war record. His outstanding achievements proved his selfless dedication to the service of his country and people, thereby bringing distinct honor to the Armed Forces of the Philippines. He is well known for his physical and moral courage, and keen sense of fairness, justice, honesty and integrity. He championed the cause of the deserving and competent reserved officers and integrees in their relentless struggle to gain meritorious recognition and achieve further competence in military service.

Alfredo M. Santos was born in Santa Cruz, Manila, Philippines, on July 13, 1905 to Fructoso L. Santos and Agatona J. Manapat, and was seventh among fourteen children. His secondary education was acquired in Manila North High school (now Arellano). He graduated at Mapúa Institute of Technology with a degree in Bachelor of Science in Civil Engineering in 1931. He showed interest in the military when he graduated on the top of his ROTC class in 1929. As a cadet colonel and Corp Commander in both institutions, he continued this interest after schooling.

General Santos' military career started when he was appointed probationary Third Lieutenant on June 8, 1936, after five years of civil engineering practice. He entered the Reserve Officer Service School (ROSS) at Camp Henry T. Allen in Baguio City, where he was made the Battalion Commander. He graduated at the top of his class, and twenty years after, he was honored as its Most Distinguished Alumnus.

Then Captain Santos was the most decorated Unit Commander of the 1st Regular Division in the memorable Bataan campaign, even dubbed by Commanding General, Brigadier General Fidel V. Segundo, as the "Hammer of the Division" when he brilliantly outmaneuvered and outsmarted the enemy during their attempt to pocket their area. In both attempts, his unit successfully broke through the Gogo - Cotar and Tuol Pockets, thus earning for himself the moniker "hero of the pockets"

For his heroic feat in battle, he was promoted to Major in the field. Two days after, he was decorated with the United States Army's Distinguished Service Cross for "extraordinary heroism in combat in Bataan" and the Silver Star for "gallantry in action". Later, the Philippine Government awarded him the equivalent Distinguished Conduct Star and Gold Cross for the same combat action.

On January 25, 1942, a superior Japanese Army force launched a determined and relentless attack southward from a general line along Pilar - Bagac Road. This attack swept the outpost line in resistance, and penetrated the Main Line of Resistance (MLR) of the 1st Regular Division on the Gogo - Cotar River area, Bataan, creating a 500 yard gap through which the enemy rushed. For four days, hundreds of death defying enemy troops tried to puncture and overwhelm the lines. Major Santos was given the hazardous mission of closing the gaps and annihilating the enemy troops who had infiltrated the lines as the gap posed a serious threat to the positions and the security of the division. With utter disregard for his personal safety, he led a counter attack against the strong and numerically superior Japanese forces positioned between the MLR and the Regimental Reserve Line (RRL). The fighting began at dawn of January 29, 1942. With dogged determination, the defenders fought assiduously and without pause against all odds to restore the defensive sector assigned to the 1st Regular Division.

Major Santos was ordered to surrender his unit to the Imperial Japanese Forces which he reluctantly did on April 12, 1942. He shared in the sufferings of those in the "Death March" to Camp O'Donnell at Capas, Tarlac, where he became a prisoner of war. He was released from the concentration camp on August 10, 1942.

The cessation of the hostilities between the Japanese invaders and the USAFFE forces did not stifle his fighting spirit and love for freedom. During the Japanese occupation from December 1942 to January 1945, he joined the Filipino - American Irregular Troops (FAIT) under Col. Hugh I. Straughn as Chief of the Intelligence Division of the North Section in Manila, with the rank of Colonel. He fought with the American and Filipino soldiers in the liberation of Manila from February to March 1945.

He returned to military control at the end of the liberation campaign that year and was assigned at Camp Murphy as Camp Inspector of the 2nd Camp Complement. Later, he held other positions of major responsibility, including Executive Officer and S-3 of the 1st Camp Complement; Acting District Commander at Camp Olivas, San Fernando, Pampanga; Commanding Officer of the 4th MP Battalion, Mandaluyong, Rizal, in April 1946; and Executive Officer of the Presidential Guard Battalion in Malacañang Palace, Manila.

In July 1946, he was sent to the United States as a student officer at the Command and General Staff College at Fort Leavenworth, Kansas, USA, where he finished the regular Command and Staff course a year later on July 3, 1947.

When Congressman Datu Mangelen and Senator Salipada Pendatun offered him the provincial governorship of Cotabato in 1951, through then Secretary of National Defense Ramon Magsaysay, he declined. It was a personal decision which was very difficult to make. At that time, the position was appointive, rather than elective. The province of Cotabato then was in turmoil. Violent clashes occurred, resulting in the death of many political followers of contending parties. But he contended that the problem was essentially political in nature, and that he had charted his course for a military career. His negative reply was honored. Major Santos knew what he wanted in his career and to him a diversion like that of the appointive offer would adversely affect his plan to attain the highest position in the military hierarchy.

Subsequently, Lieutenant Colonel Santos was given command of the Panay Task Force, composed of the 15th Battalion Combat Team (BCT) with some elements of the 9th BCT and the PC commands of Iloilo, Capiz and Antique. Reporting to his new command on March 1, 1951, he once more showed his incontestable ability and grit in military tactics. As proof of this, he earned the distinction of having accounted for the fall of two of the highest ranking dissidents at the height of the Huk campaign.

This position gave him the opportunity to put his military prowess in full play. He made history when Guillermo Capadocia, erstwhile Secretary General and one of the founders of the Communist Party of the Philippines (CPP), was captured at Barrio Yubog in San Remigio, Antique. During the hectic campaign to capture Capadocia and destroy the leftist band in 1951 and 1952 on Panay Island, Major Santos made one crucial decision which ensured the success of the operations. He organized a civilian commando unit headed by Pedro Valentin, a mountain leader who knew the people and the terrain very well. Part of his command decision was the designation of the civilian commando unit as the attacking force, while elements of the 15th BCT served as the holding or covering forces. Had it been otherwise, the wily Capadocia would have had the government forces running around at circles as they were handicapped in the rough terrain. Capadocia's death was the result of Major Santos' bold plan. The incessant military operations aimed primarily at the capture, whether dead or alive, of dissident leaders resulted in the surrender of hundreds of their men. In addition, the capture of the rebels' arms, supplies and equipment as well as important documents which were of great value to the entire campaign for peace and order throughout the country was crucial in breaking up the backbone of the dissidents' depredations in Visayas and Mindanao.

In the crucial campaign to capture Huk leader Balgos and destroy his group in the Bicol region, Colonel Santos made a decision to pull out all Army troops from the provinces of Sorsogon, Camarines Norte and Camarines Sur after an on - the - spot study and evaluation of the situation in the field. Operations then concentrated in the Manito area where the Huk leader was reportedly holed up. It was a risky decision as it left those other area at the mercy of Balgos and his marauders, headed by the murderous Commander "Tagle". But the weather proved to be an unexpected ally in Colonel Santos' operation. A strong typhoon that was raging at the time, and the possibility that Balgos could have slipped out due to the thinness of the cordon surrounding him was very evident. Balgos did try to escape but failed to do so as he encountered army troops along the trail he took. His death compensated for the great risk taken. It virtually broke the expansion phase of the HMB and CPP in the Bicol region.

Colonel Santos' deep understanding and full knowledge of the nature of the dissident underground movement enabled him to effect the intelligent deployment of his troops as well as secure the cooperation and support of the civilian population and weakening the Huk organization. Six day after his second achievement, Colonel Santos was appointed ad interim Brigadier General by President Ramon Magsaysay, a well deserved appointment which was confirmed by the Commission of Appointments on May 4, 1955.

His successful effort in the Huk campaigns spread abroad and inspired other military leaders in Southeast Asia who were locked in similar fierce battle aimed at stopping the spread of Communism in their own similar countries. As a result, he was awarded Philippine Legion of Honor (Degree of Commander) and later another Legion of Honor (Degree of Officer) from the United States Government.

In 1956, he was assigned back at Camp Murphy as Chief of the War Plans Division. As a fitting recognition for the enviable military achievement of General Santos, he was nominated and subsequently installed as the first Chief of SEATO Military Planning Office with headquarters in Bangkok, Thailand. The SEATO member nations' respect for the Filipino general was immensely enhanced by his unassailable dignity, integrity and competence in the effective organization of the said office by February 15, 1957.

On August 1, 1960, he was designated Commanding General of the Philippine Army. Upon assumption of his duties, a career management program was vigorously pursued for officers, reassigning them in accordance with their career profile. A stickler for professional excellence, he instituted rigid training for troops and required appropriate compulsory schooling of officers who were in need of it. Through his conscientious and indefatigable efforts, he efficiently carried out the broad policies and vital mission of the PA, particularly the build - up and training of the Citizen Army and the implementation of the socio - economic military program of the AFP.

He was deeply concerned with the welfare of his men and endeavored to ameliorate the living conditions of the enlisted personnel and their families, raising their morale and improving discipline in the command. To better prepare military personnel for civilian life, he pursued non-military projects that could provide opportunities to soldiers and reservists especially upon their retirement or separation from the service, in the form of practical lessons and training in livestock raising.

On the matters of promotion and assignment of officers and men under his command, Major Santos emphasized the merit system for the sake of morale and discipline. His firm, mature and unyielding decisions on administrative matters, which were tempered with and founded upon justice and human understanding, contributed to a large extent to the effective synchronization of the various PA staffs and efficient functioning of the entire command.

After having served for more than two years as Commanding General of the Philippine Army, he was appointed by President Diosdado Macapagal as Chief of Staff of the AFP on September 1, 1962, thus becoming the first military man from the ranks of the ROTC and "citizen army" to be named to the highest military post. With his ascendance to this top position, he also set precedent of being the first one - star general to be elevated directly to a three - star rank, that of Lieutenant General.

The latest honor bestowed upon General Santos was his election into the Allied Officers Hall of Fame at the United States Army Command and General Staff at Fort Leavenworth, Kansas USA. He received the Certificate of Honor from US Ambassador Henry A. Byroade in simple ceremonies held at the US Embassy, Roxas Boulevard, Manila on April 14, 1973.
