Law, reserve service and the defence of Panay
Macario Peralta Jr. was born in Manila on 30 July 1913 and graduated in law from the University of the Philippines in 1936. Reserve military training gave him a second professional path. During the 1941 mobilisation he commanded the 61st Provisional Regiment, connecting his prewar training to the defence of Panay against the Japanese invasion.
The NHCP historical marker distinguishes two milestones: his refusal to surrender at Daanbanwa, Lambunao, on 1 June 1942, and the organisation of the Free Panay Guerrilla Forces at Inadlawan, Dueñas, on 1 July. Keeping them separate explains how a decision to continue fighting became an organised resistance command.
Radio links and the Sixth Military District
Resistance depended on communication as well as combat. The U.S. Army’s history of the Leyte campaign records February 1943 correspondence and radio recognition of Peralta as commander of the Sixth Military District. Contact with the Allied command provided a framework for identifying units, sharing intelligence and arranging liaison rather than leaving every island organisation isolated.
The same account describes attempts by Peralta and Mindanao commander Wendell Fertig to coordinate neighbouring groups, including contacts in Leyte. Competing local claims complicated that process. Recognition of a regional coordinating role should not be inflated into command of every Philippine guerrilla force; wartime resistance remained a network of distinct organisations and jurisdictions.

Military resistance and civilian authority
Panay’s resistance also raised the question of who could govern while the prewar state was disrupted. In an Army History review of scholarship on wartime Panay, Ivan A. Zasimczuk describes disagreements between Peralta and governor Tomás Confesor over printing currency and paying civilian officials. These were disputes about resources and jurisdiction within resistance, not simply divisions between collaborators and patriots.
That account complicates a biography told only through battlefield success. A guerrilla commander needed supplies and local cooperation, while civilian officials sought to preserve their own authority. The review supports this limited description of their disagreement; it does not establish a judicial verdict against either man or settle every episode in their relationship.

The combined liberation of Iloilo in 1945
When American forces returned to Panay in March 1945, Peralta’s guerrillas already controlled much of the island outside the remaining Japanese positions. The U.S. Army campaign account describes the 40th Infantry Division’s operations alongside this established local force. Allied troops did not arrive in an island without resistance, nor did the guerrillas liberate every position entirely on their own.
Iloilo City was liberated on 20 March 1945. Local intelligence, secured territory and guerrilla cooperation formed part of a combined campaign with returning regular forces. Explaining that partnership gives Peralta a substantial role without erasing the other Filipino participants or the Allied units involved in the city’s recovery.
Senate investigations and national defence
Peralta’s Senate term ran from 1949 to 1955. The institutional profile credits him with a resolution investigating the Tambobong–Buenavista estate transaction and efforts concerning veterans’ priority in government employment and senators’ disclosure of assets and liabilities. These specific concerns extend his biography beyond the prestige attached to guerrilla leadership.
He later served as national defence secretary under Diosdado Macapagal from 1962 to 1965 and died on 30 December 1965. His career thus moved through three different kinds of authority: resistance command under occupation, elected legislative scrutiny and civilian cabinet responsibility for defence. None was simply a continuation of the wartime military district.
