History of the Lipa Guerrilla Headquarters Combat Team, Rillo-Neri Unit

The Rillo-Neri Unit was a guerrilla organization that was allegedly formed in the town of Balayan, and again allegedly by the authority coming from Col. Hugh Straughn, founder of the Fil-American Irregular Troops. It was supposed to have conducted intelligence work, kept peace and order and helped in the evacuation of the citizens of Balayan, Lemery and Tuy. Its combat team was also said to have participated in combat during the liberation of Batangas. While this guerrilla group failed to obtain full recognition from the United States Army, 130 of its members were recognized as a combat team and another 400 gained recognition with another guerrilla outfit, the Blue Eagle Brigade. In this document1 is contained a brief history of the Lipa Guerrilla Headquarters Combat Team, as the Rillo-Neri Unit Combat Team was renamed during the liberation period. This component of the larger Rillo-Neri Unit, unlike its mother organization, obtained official recognition from the United States Army.

PART II – ACTIVITIES OF THE UNIT BEFORE AMERICAN LANDING

Col Salvador Rillo and Lt Col Jaime Samperino Neri, SJ, were the founders of the Rillo-Neri Unit, Fil-American Irregular Troops, under Col Hugh S Straughn. To designate the Unit from the other Fil-Americans, the Rillo-Neri Unit was added in honor of the two founders.

I – After the fall of Bataan, Col Rillo called some of his close

[p. 3]

friends to a meeting for the purpose of organizing a group for the following activities:

1. To organize a group to direct dissemination of the American propaganda in the City of Manila and the Southern Provinces;

2. To raise funds and aid – clothing, food, medicine – for the American stragglers and escaped prisoners for:

a. Master, Lavesky and Barual – American employees of the Finance Department of the Quartermaster – staying with Mr Nazario in the barrio of San Jose del Monte at the foot of Ipo Mountain, Riza;

b. American Officers Capt Schalby, Lt Schaefer, Lt Moor, at Lt Silhavy, who were under the care of Mrs. Gertrudes B LaDuc, widow of an American; and

3. To do some sabotage works and, if possible, to resist small groups of Japanese patrols with what small weapons we had.

II. FORTY-SEVEN (47) SPRINGFIELD RIFLES, ORIGINAL ARMS OF THE UNIT:

HORACIO ILAGAN, ROTC Officer [of an outfit] disbanded in Manila, was requested by Col Rillo to bring to Balayan, Batangas forty-seven (47) Springfield rifles [that] Col Rillo was able to get from the Alejandro Albert Elementary School, Dapitan, Manila. On 15 April 42, Horacio Ilagan (appointed later on as res S-2 with the rank of Major) with 30 volunteer ROTC disbanded soldiers, started from Manila to bring the rifles to Batangas. By passing thru corn fields, under the coconut trees and later on crossing Mt Batulao, Maj Ilagan was successful in bringing the rifles to Balayan, Batangas.

III. COL RILLO CAUGHT on 6 June 1942 by JAPANESE MILITARY POLICE: Before the progress of the organization of the guerrilla unit in Balayan, Batangas could be reported in Manila, Col Rillo was arrested by the Japanese Military Police on 6 June 1942 at Balinwatak, Rizal, while trying to bring some supplies to the Americans at Ipo Mt. Because of this, the first try to organize a guerrilla unit under Col Rillo was foiled.

IV. MR. HORACIO ILAGAN AS GUERRILLA LIAISON OFFICER: While it is true that Col Rillo was imprisoned, yet his wife was able to get instructions from him. Maj Ilagan was told to contact Col Espina, Overall Commander of the Fil-American Irregular Troops under Col Straughn in Batangas – thru his son-in-law Maj Medrano. Maj Ilagan was appointed as Liaison Officer for the western part of Batangas Province, especially to Maj Deguito and Bahia, founders of the Pioneer Guerrillas of Balayan. Thru the efforts of Maj Ilagan, the following guerrilla organizers attached themselves to Col Espina:

Maj Distresa, founder of guerrilla movement in Nasugbu, Batangas
Maj Vicente Calingasan, guerrilla leader in Tuy, Batangas
Maj Tugegue, guerrilla leader of [the] eastern barrios of Balayan
Maj Amador Deguito, Maj Rodolfo Bahia and Maj Jose Unzon, organizers of the Pioneer Guerrillas in Balayan, Batangas
Capt Gagalac and Capt Licopa, organizers of the Glint in the towns of Calaca, Lemery and Taal, Batangas
Col Amando Ilagan, organizer of the Canluran Regiment in Taal, Batangas

V. RILLO-NERI UNIT ORGANIZED ON MILITARY FOOTING on 12 January 1945: After the killing of the different guerrilla founders and when Col

[p. 4]

Rillo was released on 25 December 42, Col Rillo went directly to Balayan, Batangas. There, he found out that most of the guerrilla organization was paralyzed because of the untimely death of the different guerrilla leaders, especially in the sector of western Batangas. The killing of Maj Deguito, Maj Bahia, Maj Tuguegue, Maj Distresa, Maj Evangelista and, finally, of Col Espina totally demoralized the different guerrilla organizations. Col Rillo ordered both Maj Pedro Zuñiga and Maj Rafael Ilagan, ex-USAFFE soldiers, to organize two BATTALIONS in the towns of Tuy and Balayan.

VI. SCHOOL FOR OFFICERS ORGANIZED: Under Col Fortunato Borbon, ex-Bataan veteran and Maj Basilio Fernando, and later on Capt Lino Inciong, other USAFFE OFFICERS, a school for officers’ training was organized at the Hq of the unit at Dao, Balayan, Batangas.

VII. REGIMENTAL HQ COMBAT TEAM ORGANIZED: Armed with the forty-seven of April 1942, a Regimental Hq Combat Team of 50 EM and 4 Officers under Capt Gregorio Arcalas was organized. This Combat Team increased in number every time the Japanese sent out patrols of less than 10 men. Such that its members were 170 EM and 6 Officers when the Americans landed in Nasugbu, Batangas on 31 Jan 45.

VII. SABOTAGE MISSIONS: On 5 August 43, Col Rillo was arrested for the runners of Col Nakar, CO of the Northern Luzon Guerrillas. Thanks that Maj Ilagan was caught him. [?] In November 43, while a strong storm was passing [over] Manila, 5 simultaneous fires started at the different depots of the Japs. Maj Ilagan, together with 10 Hunters ROTC [men], set fire to the Japanese gasoline depot at Paco, Manila. At the same time, another one was burning the depot at Grace Park and the other one at the Chinatown. A big one was eating up the supply depot near the Manila Railroad and a beautiful one destroying the ammunition depot along the seashore of Tondo, Manila.

IX. AMERICAN SOLDIERS RESCUED, CARED [FOR] AND LATER ON ESCORTED TO FREDOM: Following the surrender of Corregidor and Bataan, many American stragglers tried to cross to Looc, Batangas. Some of them found refuge at Calan, Tuy. While it is true that the Lopez family of Balayan was feeding these Americans, yet it was the RILLO-NERI UNIT soldiers who were guarding night and day these Americans. Later on the members of the Unit [took] these Americans to Mindoro for them to enjoy once more freedom. The following Americans were taken care [of] immediately after their escape from Corregidor in May 1942 up to November 1944, when they were escorted to Mindoro:

1. Capt. Bert C Fuller (Bataan escapee)
2. Major Raymond Humphrey (Bataan escapee)
3. A R M 2 C John W Montgomery (6345666) VB-15, USN Down Nov 6, 1944
4. Lt. J. G. Dondero, Donald (Bataan escapee)
5. Lt. J. G. W. Resing (251421) VB-15 USN Down on 6 Nov 1944
6. Lt. J. G. W. E. Miller (158079) VF-32 USN Down Sept 21, 1944
7. Capt Whitecomb, Airforce of USA (Bataan escapee)
8. Marine Corps Reid Chamberlain (Bataan escapee)

X. INTELLIGENCE REPORTS: Col Rillo and Fr Neri were among those lucky prisoners of war who were able to escape from Muntinglupa Bilibid Prison together with about 200 political prisoners. Both Col Rillo and Fr Neri immediately proceeded to Balayan, Batangas. By this time, the Combat Team had a strength of 141 EM and 5 officers fully armed. For the purpose of ensuring that all intelligence reports of all the guerrilla units would reach Col Nicholson (Commander Rowe), Fr Neri was sent to Mindoro in Sept

[p. 5]

1944 to be the Liaison Officer of the Unit to Col Nicholson. From time to time, regular intelligence reports were sent to Mindoro thru runners on small sailboats that crossed the ocean from Balayan, Batangas to Mindoro. Jap strength, movements of the enemy, the garrisons and fortifications, the airfield constructions, the arms of the Japs and the positions of the different artillery guns were continuously reported. Later on, Fr. Neri proceeded to Leyte.

XI. ENEMY CASUALTIES: In spite of the general instruction that the guerrilla units should avoid armed contact with the enemy, every time that the Japs gave an opportunity to inflict casualties, the Unit Regimental Hq Combat Team did not hesitate. Every time the Japs sent out patrols of not more than 10 men, no one would be able to return alive to report about what happened. Those Japs would really get their desire to reach heaven. Every time a Jap was killed, another arm was added to the unit and new recruits were accepted. Before the American landing in Nasugbu, Batangas on 31 Jan 45, the Combat Team, which started with 50 EM and 4 officers, had already a strength of 170 EM and 6 officers. Or an increase of 129 arms which naturally represented 129 Japs killed. Too bad the Japs learned their lessons quite so fast so that they never dared to send another patrol composed of 10 men only.

PART III

Your intelligence report of Feb 3 and 4 is very good. It verifies and gives us valuable information that we badly needed. Both Maj Vanderpool and I appreciate it much. Good work like that will bring sure victory so much sooner.

Maj Vanderpool awaits word on what rice you can sell to us (₱7.30) per sack, too. Send your answer to me at Guerrilla Hq.

Your courier tells me they captured a Jap saber you now have that may have a family seal and unit identity on it. Could I see that saber for intelligence information? It may give me good information on what troops are left still fighting us.

Keep up the good work and intelligence reports.

1. I wish to express my gratitude to the RILLO-NERI UNIT for the memorial work they, and all guerrilla units of Batangas and Cavite Provinces, have done.

2. I salute you as patriotic civilians turned guerrillas to protect your homes, and work side by side with the U.S. in eliminating the Japs. I gave you my assurance that your vigil yet remains only a matter of hours, before you can again stroll in your fields and cities. Other sectors of your province yet await the joyous time. We are turning our attention now to their needs.

III. ASSIGNED SECTOR OF RESPONSIBILITY – Operating Memo No 28: Two operating memos were issued by the 11th A/B Div assigning Sector of Responsibility for each attached unit to the 11th A/B Div. Memo No 28 assigned sectors of responsibilities for the different units. In my sector of responsibility, the Rillo-Neri Unit killed 42 Japs in its different patrol operations. After clearing the area, the unit was assigned to help the other units mop their respective areas.

IV. MATIPOK (86.7-169.8) Calaca, Batangas OPERATIONS: On 16 April 45, 30 EM of the Rainbow Regt, under Lt V Daguigan; 30 EM of Co “C” Hunters ROTC; 42 EM of the Batangas Fil-Americans under Lt Real; and 50 EM of the Lipa Guerrilla Hq Combat Team, under Lt Baylosis, conducted the Matipok Operation in Calaca, Batangas under the overall command of Capt Ilagan. These different guerrilla units started from different starting points from the town proper passing thru different barrios and merging at one point at Mt Matipok. While the operation did not encounter much enemy opposition, yet the operation was successful for it was the cause for the return of the evacuated farmers to their fields. Operation was for 3 days from 16 to 19 March 45. 11 Japs encountered and killed.

V. BARRAGON (87.4-170.1) Lemery, Batangas OPERATIONS: After 4 days of patrolling with 30 EM, Capt Horacio L Ilagan cornered about 50 Japs on a hill-mole of Baragon, Lemery. There was only one lone trail two feet wide

[p. 13]

to the position of the Japs. The trail was covered by two Jap 30 cal machine guns. After trying the enemy for e [a few?] minutes, Capt Ilagan decided to withdraw 400 yards from the enemy to a good place protected by natural terrain. Capt Ilagan could not penetrate the enemy line, but the Japs, too, could not go out [of] their position. So, Capt Ilagan asked for reinforcement and artillery support. At about 1660, the Reconnaissance Patrol of the 188th Reg A/B Div was directed by cab to where Capt Ilagan was. This American unit had already received 3 false alarms during the day, so that the American Lt and 1st Sgt refused to believe that there were Japs in the area pointed by Capt Ilagan. In spite of Capt Ilagans advice to attack the Japs by that time, the operation would [be] overtaken by darkness, the American Lt ordered the attack. Covered by trench mortar fire and one machine gun, the Americans and 30 EM of Capt Ilagan attacked the Japs’ position. [The] Japs held their fire until we were 20 yards from their position. They opened fire and Sgt Besas, the American 1st Sgt, were terribly wounded. The American Lt was shot in the left arm. Darkness overtook operations. The Cab ordered Capt Ilagan to go back to his former position and to watch the Japs for the whole night. On 21 May 45, the 188th Bat 11th A/B Division under Maj Alexander and the Rillo-Neri Unit of 5 EM under Capt Ilagan, attacked and got every Jap. Japs killed and counted, 39. [The] Operation covered up 4 days from 18 to 21 May 45.

VI. CACAWAN TO CAHEL (85.7-169.4) Calaca, Batangas OPERATIONS: Patrol reports sent by the guerrilla units stationed at Calaca, Batangas verified the reports of the civilians that the Japs [had] driven from Matipok Operation went to contact the Japs covering the area around Cacawan and Cahel, Calaca, covering an area of about a square mile. Lt McDonald sent Capt Ilagan with 30 EM to check the report. After an encounter with the enemy for about 10 mins, Capt Ilagan decided to retreat because the enemy was now in numbers, in a better position, and with better and bigger arms. Lt Conlon, Unit Training Officer, refused to believe Capt Ilagan’s reports. So, on 3 June 45, Capt Ilagan and Lt Conlon with 3 EM, decided to try once again the enemy. This time, Lt Conlon agreed with Capt Ilagan.

On 17 June 45, the entire 188th Bat 11th A/B Div under Maj Alexander together with 80 EM and officers under Capt Ilagan, decided to attack the Japs. The Jap position was shelled for two continuous nights and days with 105 cal guns before the 188th and the Lipa Guerrilla Hq Combat Team could get [to] the Japs’ position. Japs killed and counted 108 with several more which could not be determined because the bodies were scattered into pieces.
