The President of the United States of America, in the name of Congress, takes pleasure in presenting the Medal of Honor to First Lieutenant William Wallace McCammon, United States Army, for extraordinary heroism on 3 October 1862, while serving with Company E, 24th Missouri Infantry, in action at Corinth, Mississippi. While on duty as Provost Marshal, First Lieutenant McCammon voluntarily assumed command of his company, then under fire, and so continued in command until the repulse and retreat of the enemy on the following day, the loss to this company during the battle being very great.
