His temporary rank had gone to his head, and he is reported to have shown considerable severity and hauteur in his treatment of his former neighbours in Guinobatan, to which place he had returned at the close of the insurrection.

Meanwhile, a wealthy Chinese _mestizo_ named Don Circilio Jaucian, on whom Ola, during his brief career as an Insurgent officer, had laid a heavy hand, had become _presidente_ of the town.
Smarting under the indignities which he had suffered, Jaucian made it very uncomfortable for the former major, and in ways well understood in Malay countries brought it home to the latter that their positions had been reversed.

Ola's house was mysteriously burned, and his life in Guinobatan was made so unbearable that he took to the hills.
Ola had held higher military rank than had any of his outlaw associates, and he became their dominating spirit.

He had no grievance against the Americans, but took every opportunity to avenge himself on the _caciques_ of Guinobatan, his native town.
Three assistant chiefs of constabulary, Garwood, Baker and Bandholtz, were successively sent to Albay to deal with this situation.

Baker and Bandholtz were regular army officers.
