On September 1, 1932, Peruvian civilians crossed into Colombian territory and invaded the town of Leticia in the Colombian Amazon claiming that the town was Peruvian territory. The Colombian military aviation only had 11 instructors, four Curtiss-Wright CW-14R Osprey air combat support planes and one Curtiss Falcon O-1. The military aviation then received full financial support from the Congress of Colombia. Colombia bought aircraft from Germany and the United States, while others were activated from the airline operating in Colombia SCADTA (Sociedad Colombo-Alemana de Transporte Aéreo) and their pilots, which included some German citizens, one of these was Major Herbert Boy. The imported aircraft were 4 Junkers F.13, 4 Junkers W 34 and 3 Junkers K 43, 6 Junkers Ju 52, 2 Dornier Merkur II, 4 Dornier Wal, 20 Curtiss Falcon F-8F and 30 Curtiss Hawk II F-11C.
