The Manuripi campaign was an armed confrontation between Bolivian and Peruvian troops and a group of indigenous people in 1910. The Bolivian press has treated this conflict as "forgotten" due to the little importance with which it is taken in the country's history,^[1] perhaps due to the singularity of the confrontation, since a treaty had already been signed several months ago that awarded those territories to Peru.

At that time, the borders between Peru and Bolivia were not well defined, and the Argentine arbitration of July 9, 1909, caused tensions to rise. During this, Bolivian Captain Lino Echeverría and 16 men remained in the small fortress of Avaroa on the Manuripí River. This led to fighting, and on June 21, 1910, Echeverría repelled an attack by 25 Peruvians, with losses on both sides. This was followed by the Peruvian 5th Infantry Regiment, consisting of 180 men, 2 machine guns, and 20 canoes, landing at the confluence of the Manuripi and Mejahuirra rivers on July 22.^[2] It is believed^{[by whom?]} that the arrest of a smuggler by Bolivian troops further heightened tensions. Two months later, a force of 150 Peruvian and indigenous soldiers presented an ultimatum to the fort held by Echeverria. During the ensuing attack, Echeverria and three other Bolivian soldiers were killed while defending the fort, and several prisoners were taken.^[3]
