Peruvian accounts state that in November 1994, a Peruvian patrol, advancing through the Cenepa headwaters, was intercepted by an Ecuadorian patrol. Being told they had crossed into Ecuadorian territory, the Peruvians were escorted to the Ecuadorian outpost of "Base Sur", where the patrol was given supplies before continuing their journey. Afterwards, realizing Base Sur was actually in Peruvian-claimed territory, the Peruvians asked the Ecuadorians for a meeting of superior officers. The meeting, which the Peruvians date to December 20 and the Ecuadorians to December 12, took place in "Base Sur", between the commanders of the opposing battalions in the area.
