First Medal of Honor action occurred 13 February 1861

Many people think the Medal of honor came about and was first awarded during the Civil War. Actually, thee first MoH was awarded to a Doctor for his actions in a fight between a U.S. Army Infantry and Chiricahua Apaches. Read the below article from History.com

The earliest military action to be awarded a Medal of Honor is 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 14 and proved instrumental in breaking the siege. The first U.S.-Apache conflict had begun several days before, when Cochise, the Chiricahua Apache chief, kidnapped three white men to exchange for his brother and two nephews held by the U.S. Army on false charges of stealing cattle and kidnapping a child. When the exchange was refused, Cochise killed the white men, and the army responded by killing his relatives, setting off the first of the Apache wars.

Although Irwin’s bravery in this conflict was the earliest Medal of Honor action, the award itself was not created until 1862, and it was not until January 21, 1894, that Irwin received the nation’s highest military honor.
