U.S.M.C. Lieutenant Frank S. Reasoner—who became the first Marine awarded the prestigious Medal of Honor posthumously for action in Vietnam—is killed by enemy fire on July 12, 1965. He was the second Marine overall to be awarded the nation's highest award for valor during the Vietnam War.

Reasoner and his battalion had been on a sweep of a suspected Viet Cong area to deter any enemy activity aimed at the nearby airbase at Da Nang. He and the five-man point team he was accompanying were cut off from the main body of the company. He ordered his men to lay down a base of fire and then, repeatedly exposing himself to enemy fire, killed two Viet Cong, single-handedly wiped out an enemy machine gun emplacement, and raced through enemy fire to rescue his injured radio operator. Trying to rally his men, Reasoner was hit by enemy machine gun fire and was killed instantly.

When Navy Secretary Paul H. Nitze presented the Medal of Honor to Reasoner’s widow and son in ceremonies at the Pentagon on January 31, 1967, he spoke of Reasoner’s willingness to die for his men: “Lieutenant Reasoner’s complete disregard for his own welfare will long serve as an inspiring example to others.”

Lieutenant Reasoner was the first Marine to receive the Medal of Honor posthumously for action in Vietnam. The first Vietnam War Marine to receive the Medal of Honor was Robert Emmett O'Malley, who received his medal almost two months earlier.

First Medal of Honor and the Great Locomotive Chase

The Medal of Honor is given to America's bravest heroes, and the first people to receive it certainly proved their courage.
