These are the Curtiss JN-3 airplanes of the U.S. Army's First Aero Squadron, which flew from a newly-established base at Columbus, NM following Villa's raid, to Pershing's headquarters at Casas Grandes, Chihuahua, Mexico on March 19 and 20, 1916.

According the Wikipedia account, these planes proved unsuitable due to the altitude and heat conditions, and were returned to Columbus by April, 1916.
