The Ecuadorian Army, evidently bent on preventing any repetition of the "Pachacútec" incident, and to forestall any Peruvian attempt to reach to crests of the Condor range, had gone on to establish a "defensive" perimeter on the area of Cenepa valley, with two outposts, "Tiwinza" and "Base Sur", on the Cenepa headwaters (i.e. in the eastern side of the Cordillera del Cóndor, in Peru's land), and a larger outpost, "Coangos", on the high ground overlooking them from the north (see map).
