The Paquisha War or Fake Paquisha War () was a military clash that took place between January and February 1981 between Ecuador and Peru over the control of three watchposts. While Peru felt that the matter was already decided in the Ecuadorian–Peruvian War of 1941, Ecuador claimed that the Rio de Janeiro Protocol was not executable because a 78 km section of the border was not precisely defined. In the aftermath of the incident, both sides increased their military presence along the Cordillera del Cóndor area and Cenepa Valley, starting an escalating spiral of tension and provocation that finally resulted in another military confrontation in 1995, the Cenepa War. While the name Paquisha War is widely used by the international community and Ecuador, in Spanish this incident is also known as the Falso Paquisha War (Conflicto del Falso Paquisha) in Peru and, occasionally, as the Paquisha Incident or the Upper Comaina Conflict (conflicto del Alto Comaina). Historical background For details on the history of the border dispute between Ecuador and Peru, please see History of the Ecuadorian–Peruvian territorial dispute. The Paquisha or "False Paquisha" Incident The conflict began on January 22, 1981, the day on which the Peruvian government denounced the attack on one of its aircraft that was carrying out a supply mission destined for border surveillance posts on the Comaina River. Peruvian President Fernando Belaúnde Terry ordered the inspection of the river until its source located on the eastern side of the Condor range (in Spanish, Cordillera del Cóndor). In this inspection, three Ecuadorian detachments were found with facilities in the territory considered to be Peru by the Peruvian Government according to the previous treaties. These detachments had captured the old observation posts Nos. 22, 3 and 4. The Ecuadorian position indicated that these detachments corresponded to the "Paquisha" base established in Ecuadorian territory. But, after measuring the coordinates, it was found that they did not correspond to the aforementioned Paquisha accepted in the Rio de Janeiro Protocol but, as Peruvian President Fernando Belaúnde described it, to a "False Paquisha", a name he gave it to be able to easily distinguish it from the first Paquisha that was legal under the Rio Protocol of 1942. The establishment of these posts was considered by the Peruvian Government as a violation of a status quo line arranged between the military leaders of both countries in the course of several meetings
