Since the introduction of the Medal of Honor at the beginning of the Civil War, only 19 men have received it twice.
Five received both the Army and Navy version for the same action. Four Navy sailors received two for actions during peacetime. Before the 20th Century, a number of Medals of Honor were bestowed for any valorous action – because it was the only medal at the time.
However, there are still 3 men who earned the Medal of Honor as we've come to know it – by gallantry in the face of the enemy – twice.
Those three men were John McCloy, U.S. Navy, and Daniel Daly, and Smedley Butler, both U.S. Marines .
The three men's paths would cross during the Boxer Rebellion in China, the Caribbean campaigns, and World War I.
The Boxer Rebellion
In early 1900, the United States and seven other nations dispatched forces to China to quell the Boxer Rebellion and to protect their national interests.

He earned the Navy Cross during the battle, reportedly because having a third Medal of Honor would have simply been ridiculous.
McCloy commanded the minesweeper USS Curlew during the Great War. He received a Navy Cross for his part in clearing the North Sea mine barrage after the war.
