Battle of Angoteros (1903)

The Battle of Angoteros was an armed clash that occurred on June 26, 1903, between troops from Peru and Ecuador in the area of the Napo River; originated by the advance of an Ecuadorian detachment in Peruvian territory. The Peruvian troops were commanded by Captain EP Juan Chávez Valdivia and Ensign Oscar Mávila Ruiz. This event revived the need to reach an agreement, so on February 16, 1904, both parties agreed to continue the arbitration trial before the King of Spain.

Another armed incident occurred shortly after, this time in Torres Causana, on July 28, 1904, where once again the Peruvians rejected an Ecuadorian advance on their territory.
