The sheer carnage of the, America’s deadliest war, inspired Memorial Day as a way to honor the war dead. The observances originally were called Decoration Day because thankful Americans decorated and cared for soldiers’ graves. “Memorial Day” usage began appearing in 1882, but “Decoration Day” was common until post-World War II. Congress officially changed the name in 1967,
Keep noon and 3 p.m. local time in mind today. At noon, all flags lowered to half-staff should be raised completely for the remainder of the day. And at 3 p.m., a National Moment of Remembrance takes place. President Bill Clinton started the tradition in 2000.
Arlington National Cemetery in Arlington County, Virginia, is a military cemetery in the United States of America, established during the American Civil War on the grounds of Arlington House, formerly the estate of the family of Confederate general Robert E. Lee's wife Mary Anna (Custis) Lee, a great grand-daughter of Martha Washington. The cemetery is situated directly across the Potomac River from the Lincoln Memorial in Washington, D.C.
In an area of 624 acres (253 ha), veterans and military casualties from each of the nation's wars are interred in the cemetery, ranging from the American Civil War through to the military actions in Afghanistan and Iraq. Pre-Civil War dead were reinterred after 1900.
Each year, members of the 3rd U.S. Infantry regiment, also known as the Old Guard, are charged with placing American flags at the graves of each service member in Arlington National Cemetery. Created in 1784, the regiment is the oldest active duty regiment in the U.S. Army.
The Tomb of the Unknowns has been perpetually guarded since July 2, 1937, by the U.S. Army. The 3rd U.S. Infantry Regiment ("The Old Guard") began guarding the Tomb on April 6, 1948. There is a meticulous routine which the guard follows when watching over the graves.
The Tomb Guard:
Marches 21 steps down the black mat behind the Tomb.
Turns, faces east for 21 seconds.
Turns and faces north for 21 seconds.
Takes 21 steps down the mat.
Repeats the routine until the soldier is relieved of duty at the Changing of the Guard.
After each turn, the Guard executes a sharp "shoulder-arms" movement to place the weapon on the shoulder closest to the visitors to signify that the Guard stands between the Tomb and any possible threat.
Twenty-one was chosen because it symbolizes the highest military honor that can be bestowed—the 21-gun salute.
Each turn the guard makes is precise and is instantly followed by a loud click of the heels as he snaps them together. The guard is changed every half hour during daylight in the summer, and every hour during daylight in the winter and every two hours at night (when the cemetery is closed to the public), regardless of weather conditions.
