[7] During his service, Harmon became a Mess Attendant First Class and was serving aboard the San Francisco during the Naval Battle of Guadalcanal.

[9] The President of the United States of America takes pride in presenting the Navy Cross (Posthumously) to Mess Attendant First Class Leonard Roy Harmon, United States Navy, for extraordinary heroism and devotion to duty in action against the enemy while serving on board the Heavy Cruiser U.S.S.

In addition to displaying unusual loyalty in behalf of the injured Executive Officer, he deliberately exposed himself to hostile gunfire in order to protect a shipmate and, as a result of this courageous deed, was killed in action.

His heroic spirit of self-sacrifice, maintained above and beyond the call of duty, was in keeping with the highest traditions of the United States Naval Service.
