Various Affidavits in Support of the Triumvirate Guerrillas


The Triumvirate Guerrillas was a purported guerrilla outfit that operated in Lemery, Taal and San Luis with its headquarters in the last town. The organization failed to gain official recognition from the United States Army and was even accused of being a fake organization. In this page1 are various affidavits signed by different personalities which were submitted to the United States Army as supporting documents in support of the Triumvirate Guerrillas’ application for official recognition.

I, Mariano H. Cabarrubias, Colonel, Infantry Guerrilla, Blue Eagle, now residing in Nasugbu, Batangas, depose and say the following:

That, since 1942, I personally knew of the existence of and organized guerrilla unit in San Luis, Taal and Lemery named “TRIUMVIRATE GUERRILLAS” or Diokno’s Guerrillas, with its Headquarters at San Luis, Batangas.

That the Headquarters of the Triumvirate Guerrillas in San Luis were the Central Headquarters of all other Guerrilla Units that made contact with the Visayan and Mindoro Guerrillas. That this [group] Triumvirate Guerrillas was organized by Col Narciso Diokno and he is the CO at the same time. I knew [at] one time the son of Col. Diokno, Lt. Rafael Diokno, with other guerrillas capsized on the way back to Batangas from Abra de Ilog, Mindoro, when they contacted ranking officers of the Mindoro Guerrillas.

That on March 1945, Major Leodigario Diokno of the Triumvirate Guerrillas, with his men numbering about forty strong, were in Balayan bound for Nasugbu to ask aid from the Landing Party due to the abuses of the Japs in Lemery, Taal and San Luis, Batangas. As CO of the Rainbow Regiment Guerrillas and assigned in charge of the Balayan Sector, I personally requested Major Leodigario Diokno to lend us some of their arms so as to have a mass attack on Makukak, but instead they fought with us side by side with the 158 RCT (USA). In the fight in San Piro, Balayan, they also cooperate with us in the operation and in the said fight, Capt. Amado Diokno was slightly wounded; Lt. Constantino Diokno was seriously wounded, taken to Leyte by plane, and 2nd Lt. Ernesto Diokno [was] also wounded, taken to San Jose, Mindoro by plane.

That the rest of the party of Major Leodigario Diokno joined the advancing forces to Lemery.

That in the liberation of San Luis, Batangas, they fought side by side with the Landing Forces and they had contributed greatly to the early defeat of the Japs, especially those in Bagong Tubig and Durungao, San Luis.

In witness thereof, I have hereunto set my hand this 20th day of June 1946.

I, IRENEO M. CABRERA, Filipino, Major, Phil. Army, after having been duly sworn, depose and say:

That during the Japanese occupation, I participated in the resistance movement as an officer in the Blue Eagle Unit in Lemery, Batangas, and after the liberation of the said town, I was appointed military mayor;

That while engaging in guerrilla activities, I learned of the underground work of the TRIUMVIRATE GUERRILLAS organized sometime in June, 1942 by Major Leodegario B. Diokno, Guer., and Capt. Pedro B. Diokno, Guer. (the latter also the occupation and liberation mayor of San Luis);

That the said organization rendered invaluable assistance to our unit, as well as to other units like those of Ramsey, Barilea, Peralta, and even directly to Lt. Comdr. George F. Rowe alias Nicholson of the Advanced Hq, Special Unit, SWPA;

That I have direct personal knowledge of the following activities of the Triumvirate Guerrillas:

1. Hiding and giving material aid during the early days of the occupation, to ex-USAFFE men like Col. Amando Ylagan, Lt. Col. Marcelino de la Rosa, Major Jose de la Rosa, and many enlisted men who fled from Bataan and Corregidor;

Participation (active) in the liberation campaign: its men took part in the fighting in San Piro and Makokak, Balayan, Batangas and three of its officers were wounded; its men also fought side by side with the 158 R.C.T. in the Taal-Lemery-San Luis Sector, thus contributing in a large measure to its liberation at the cost of six men killed and many wounded.

That, if called, I am willing to testify further as to the activities of the Triumvirate Guerrillas.
