 He arrived at an opportune time, as it turned out, for a particularly zealous Yakan chieftain named Datu Kalun (also spelled Kalung and Kalum) wanted to rid Lamitan of its small but growing Christian presence.The Christian community got wind of this plan, however, and Pedro Cuevas characteristically volunteered to lead the resistance composed of the Chavacanos and their Yakan converts and sympathizers.In the confrontation between the two groups, the Yakan Datu Kalun was subsequently slain and his supporters roundly defeated.
