Pancho Villa - Following guerilla leader Pancho Villas raid on Columbus, New Mexico (in which 16 Americans died), President Wilson sent Gen. Blackjack Pershing and 10,000 soldiers into the mountains of northern Mexico to hunt Villa down. The mission ultimately failed but Mexicans viewed the act as an unjust invasion. It is said that the pejorative designation gringo came from this time, as US soldiers clad in olive uniforms were met with cries of Green, Go!
