The Treaty of Pinsaqui ends the short but bloody war between Ecuador and Colombia
Disputes between Ecuador, ruled by the conservative Garcia Moreno, and Colombia, under the liberal Tomás de Mosquera, erupted when a Ecuadorian army crossed into Colombia only to meet complete defeat. The Colombians invaded in turn but the Treaty of Pinsaqui ended the short conflict, restoring affairs to their pre-war status. (By John Osborne)
