Macario Peralta, Jr. (July 30, 1913 – January 7, 1975) was a Filipino soldier, lawyer, senator and Secretary of National Defense.
Born in Manila on July 30, 1913 of Ilocano-Pangasinan descent, Peralta grew up in Tarlac. He finished his Bachelor of Laws degree at the University of the Philippines, graduating cum laude, in 1936. He passed the bar the same year, obtaining second place to Diosdado Macapagal.
Peralta joined the Philippine Army in 1936 as a reserve officer and was later commissioned in the regular force as second Lieutenant. His first assignment was in Cebu as Commandant of the Visayan Institute ROTC cadets, later at the Adamson University in Manila. He attended the Philippine Army Infantry School in 1940, finishing at the top of his class.
War found him back in the Visayas as Chief of Operations of the 61st Division, then being mobilized in Iloilo. After the surrender of the USAFFE troops to the Japanese, Peralta, then a Col., organized and led the guerrillas in Panay,Romblon, Palawan, Marinduque and portions of Masbate and Mindoro, all in or bordering the Western Visayas. Col. Peralta's guerrilla forces controlled much of Panay when the Americans returned on 18 March 1945.
In this resistance campaign against the Japanese, Peralta displayed his exemplary leadership, competence and gallantry in action. For this he was awarded the Distinguished Service Star. The United States government conferred on him the Distinguished Service Cross and the Silver Star. The Distinguished Service Cross was presented to him on Panay, soon after liberation, as can be seen in this video on YouTube of the Panay landing taken by the Army Pictorial Service.
