The contingent was then sent to southern Colombia to fight Peruvian forces with the main mission of delivering supplies to the front lines, aerial reconnaissance and air to land attacks. The fleet was divided into three squadrons with Puerto Boy as the main camp site. Support bases were in Caucaya airstrip (Puerto Leguízamo), El Encanto, Puerto Arica, La Pedrera and Tarapacá. The main combat operations started on February 14, 1933 in Tarapacá where the Peruvian garrison was bombed by seven Colombian aircraft and later assaulted by land forces. Later, on March 26, in the village of Guepi eleven Colombian planes and two cannon boats (MC Cartagena y MC Santa Marta) bombarded Peruvian positions and took over the town.
