Morning Oregonian, 28 June 1916. Caption reads: To the right stands Lieutenant Henry R. Adair of the Tenth Cavalry. To the left if Captain G. F. Trevino, an officer of General Garcia’s staff. The photograph was taken recently at a Conference held between United States and Mexican officers at the American base camp.
The last task of the expedition was to scout around Villa Ahumada, Chihuahua, Mexico “to recon in the vicinity of the Santa Domingo Ranch” and avoid any confrontation with the Carrancistas. This was about 60 miles east of Colonia Dublan where the main U.S. Army camp was set.
At Carrizal, Chihuahua American troops came face to face with a much larger force of Carranza’s Mexican troops, and a battle began. A Sergeant sought to take reinforcements of ammunition to trapped troopers at the time of the surprise attack in Carrizal. Wounded and surrounded, with his final orders “go on sergeant”, 1st Lt Adair willingly relinquished the last chance of saving his own life.
1st Lt Adair was slated to be promoted to Captain on July 1, 1916.
His father died a couple of weeks after and was never told that his son was killed. They were buried together at the same time.
