The ambush carried out by the fighters of the Reynaldo Pinon Command of the New People's Army RPC-NPA) on the 45th IB PA on April 12 in Sitio Minanga, Bigao, San Mariano was a splendid victory.
Three soldiers were killed in the said battle and three troops were also wounded. The NPA sustained no casualties. According to Vic Balligi, spokesperson of the RPCNPA, this tactical offensive was carried out amidst an onrush of military operations of the 45th IB and the 52nd Recon Coy in the towns of San Mariano, Ilagan and Benito Soliven, Isabela, which they had been conducting since March 29. The NPA used a command detonated explosive to ensure that it would only explode when the targeted vehicle carrying the enemy troops passed.
The people rejoiced over the punishment of the troops of the 45th IB who had long made them suffer and inflicted violence on them. At no time did the residents of Minanga agree to the military basing in their area. Under the 45th IB, intimidation and the interrogation of barrio folk and the illegal inspection and ransacking of their loads to and from the barrio were rampant. There were instances when the military would also fire their guns indiscriminately.
The NPA timed its tactical offensive with the visit of the chief commander of the 502nd Bde. Gen. Rolando Senga. To cover up his embarrassing failure to thwart the NPA attack, Capt. George Domingo invented the story that they recovered two guns from the ambush site and that the two fighters they had supposedly wounded were now dead.
