The earliest military action to be awarded a Medal of Honor was performed by Colonel Bernard J.D. Irwin, an assistant army surgeon serving in the first major U.S.-Apache conflict. Near Apache Pass, in southeastern Arizona, Irwin, an Irish-born doctor, volunteered to go to the rescue of Second Lieutenant George N. Bascom, who was trapped with 60 men of the U.S. Seventh Infantry by the Chiricahua Apaches. Irwin and 14 men, initially without horses, began the 100-mile trek to Bascom’s forces riding on mules. After fighting and capturing Apaches along the way and recovering stolen horses and cattle, they reached Bascom’s forces on February 13 and proved instrumental in breaking the siege.
