tomb of the unknown soldier

     The tomb of the unknown soldier is a real American tradition--not pretend. There is a real dead soldier, killed in combat, buried in a tomb, with a memorial. Each of these "unknown soldiers" is someone whose body could not be identified. In this way the one soldier stands for all of the soldiers killed in the war. The unknown soldier of the American Revolution (1775-1783) is buried here in Philadelphia, with a perpetual flame as a memorial.
