Tomb of the Unknowns

Arlington's First Official Unknown Soldier

At Arlington National Cemetery, the subject of a new WETA program that premieres Feb. 5 at 8 p.m., one of the most haunting features is the Tomb of the Unknowns, also known as the Tomb of the Unknown Soldier.

On the rear of the monument, there's a haunting inscription: Here rests in honored glory, an American soldier known but to God.

But the story of how the first official unknown soldier from World War I was selected for burial in the graves alongside the monument is a strange one. For one, he wasn't actually the first unidentified casualty to be entombed at Arlington.
