October 23, 1921 – in the French town of Chalons-sur-Marne, an American officer selects the body of the first “Unknown Soldier” to be honored among the approximately 77,000 United States servicemen killed on the Western Front during World War I.

Bearing the inscription “An Unknown American who gave his life in the World War,” the chosen casket traveled to Paris and then to Le Havre, France, where it would board the cruiser Olympia for the voyage across the Atlantic. Once back in the United States, the Unknown Soldier was buried in Arlington National Cemetery, near Washington, D.C.
