Don Juan Requejo Guerrero, the fourth mayor of the province of Bagua, recalls that the natives staged three consecutive attacks on the town of Copallín Viejo.

According to priest José Maria Guallart, in 1845 a group of aguarunas, including women, visited Copallín Viejo (today the Hillocks of Aramango) to trade copal, parrots, and changuitas for machetes and axes.

Since history tells the story of winners and the influential rather than losers and commoners, the natives of Copallín have been labelled as savages dedicated to butchery and looting, while the colonists are often portrayed as innocent and defenseless.

Records show that in 1857, natives assaulted the ancient village of Copallín, killing its inhabitants, destroying its crops, appropriating its goods, and taking its women.

Those who escaped the slaughter, among them some Huatangari, continued to seek out sympathetic and hospitable populations for some time, until the inhabitants of The Freckle claimed a section of land where they grouped and, in 1860, founded a village called New Copallín.
