Tomb of the Unknowns
This hallowed place of tremendous respect has more of a story behind it than you might think.
Hamilton Fish
Inside the Arlington National Cemetery is the Tomb of the Unknowns. It's a mandatory stop point for any visitor wanting to recognize and appreciate the many sacrifices made by America. The tomb itself came from an act of Congress, written, sponsored and published by Hamilton Fish, a Congressman from New York who had fought with the Harlem Hellfighters in World War I. 

Fish was the founding member of The American Legion and Chairman of the three person committee which wrote our American Legion Preamble. Fish was elected as a Past National Commander in 1979. He served in Congress for 24 years and lived to be 102. He accomplished many things during his lifetime. One of them was the construction of the Tomb of the Unknows (Soldiers).

On December 21, 1920, Congressman Hamilton Fish introduced Resolution 67 of the 66th Congress, which provided for the return to the United States the remains of an unknown American soldier killed in France during World War I and for interment of his remains in a hallowed tomb to be constructed outside the Memorial Amphitheater in Arlington National Cemetery in Arlington, Virginia across the Potomac River from the nation's capital. Congress approved the resolution on March 4, 1921. On October 23, 1921 at Châlons-sur-Marne, France, about 90 miles from Paris, remains of an unknown soldier were selected from among four caskets containing remains of unknown American soldiers killed in France. The selected remains were returned to the United States and interred at the tomb site in Arlington on November 11, 1921 in solemn ceremony following a state funeral procession from the U.S. Capitol building where the World War I Unknown had lain in state. The tomb, completed in 1937, came to be known as The Tomb of the Unknowns (Soldiers) which is today guarded around the clock daily by elite sentries of the U.S. Army's historic ceremonial but combat-ready 3rd Infantry Regiment—"The Old Guard." The tomb, and unknown soldiers of three U.S. wars interred there today, is thought to be the most hallowed military site in the United States and may well be Fish's greatest legacy to the nation.
A short note from the editor:
The Arlington National Cemetery had recently received another bomb threat. The visitors in the cemetery had to be evacuated for the day. The individual who did this most likely doesn't understand or appreciate the freedom won for them because of the great sacrifice made by those who now rest in peace. It is with great hope that authorities find the culprit who did this and the person comes to a new understanding what true freedom and patriotism is. 

Thank you from a grateful nation to all who have honorably served and sacrificed so much!
