Army Maj. Gen. Fox Conner ordered an armed military guard for the Tomb of the Unknown Soldier on 24 March 1926, and it has been maintained with honor ever since.
The Tomb, located at Arlington National Cemetery, was dedicated on Armistice Day (now Veterans Day) in 1921, but was at first unguarded. Responding to concerns that the site was not receiving the proper respect from tourists, Conner, then the Deputy Chief of Staff of the Army, ordered a guard drawn from the 3rd Cavalry Regiment at nearby Fort Myer (now Joint Base Myer-Henderson Hall). The original day guard was extended to a round-the-clock watch in 1937.
Today, a single M14-armed volunteer Sentinel stands guard over the Tomb at any given moment, with two reliefs rotating on a 24-hour shift. The Sentinels are changed every hour (on the hour) in winter months (October through March), and every half hour during the warmer months from April through September.

In an ode to the 21-gun salute to the Unknowns, as described by Arlington National Cemetery, “The Tomb Guard marches exactly 21 steps down the black mat behind the Tomb, turns, faces east for 21 seconds, turns and faces north for 21 seconds, then takes 21 steps down the mat and repeats the process.”
The two relief Sentinels, along with two (E-5) Assistant Relief Commanders and a sidearm-carrying (E-6) Relief Commander, are on duty in their quarters under the Memorial Room of the Tomb’s Amphitheater. The pistol is loaded with a 21-round magazine.
Since 2018, the Relief Commanders have carried specially made ceremonial SIG Sauer P320 M17 9mm pistols that carry a high-polish DLC coating and are filled with details honoring their task– while still being functional. They replaced a set of Beretta-made M9s, which were used by the guard since 1988, walking on over 11,000 consecutive days.
Each of the current four pistols bears a name — Silence, Respect, Dignity, or Perseverance— which is featured on the dust cover. The wood grip panels come from the decking of the old cruiser USS Olympia, which brought the Great War Unknown from France in 1921. The removable optics plate is engraved with a copy of the Greek Figures featured on the east panel of the Tomb, representing Peace, Victory, and Valor, repeated on the magazine floor plates. The front sight contains a vial of marble dust collected from the Tomb of the Vietnam Unknown in 1998 when he was disinterred for identification. The cocking serrations on the slide are engraved “XXI” in an ode to the 21-gun salute. Further, they all use a serial number which includes “02JUL37”, the date the guard went 24-hours.
The four serial numbers are: LS02JUL37A21 (Silence), LS02JUL37B21 (Respect), LS02JUL37C21 (Dignity), and LS02JUL37D21 (Perseverance).

The optics plate is engraved with three Greek figures. As noted by the Army, “Peace holding a dove, Victory holding a palm branch, and Valor holding a sword. Victory stands between peace and valor to reward the devotion and sacrifice that went with courage to make the cause of righteousness triumphant.” (Photos: Staff Sgt. Oscar Toscano/U.S. Army.)
The grips feature the crest of the Tomb of the Unknown Soldier Identification Badge on one side and the 4th Battalion, 3rd Infantry Regiment crest on the other. Note the engraved magazine base pads. (Photos: Staff Sgt. Oscar Toscano/U.S. Army.)

The above memorial is the mast of the lost USS Maine (Battleship No. 10), sunk in 1898, an event that sparked the Spanish-American War. It was dedicated at the cemetery in 1915 after the warship was raised.
Among the images were some of the Sentinels of the Tomb of the Unknown Soldier, who stand watch 24 hours a day, 365 days a year, in any weather.
The mortal remains of that initial Soldier, whose identity was only “Known but to God,” was selected from unknown Americans who gave up their lives in France during the Great War. Over 38,000 Americans were buried in French soil at military cemeteries in the Meuse-Argonne, St. Mihiel, Somme, and Aisne-Marne regions. One set of unidentified remains were selected from each cemetery for review.
From those four sets of identical flag-draped caskets, a decorated GI who had served in the conflict and had been twice wounded, Sgt. Edward F. Younger, selected one to become the Unknown Soldier by resting a bouquet of white roses on its cover. The Unknown was then taken to the port of Le Harve under a ceremonial escort provided by French and American troops and attended by thousands of locals along the way.
André Maginot, the French Minister of Pensions, presented the French Legion of Honor– the country’s highest order of merit– to the Unknown Soldier.

The casket was carried aboard Dewey’s old flagship, the armored cruiser USS Olympia (C-6; CA-15; CL-15; IX-40) on 25 October by Sailors and Marines while the warship’s band played both the American and French national anthems as well as Chopin’s “Funeral March.”

Installed on one of the cruiser’s topside hatches, the Unknown was guarded by Marines and Sailors for the voyage across the Atlantic to the Washington Navy Yard, where Olympia arrived on 9 November.

There, the remains were transferred to the escort of the Army.
After laying in state at the Capitol Rotunda for two days and being visited by 90,000 people, the casket was transported to Arlington on Armistice Day, celebrating the end of the Great War that had occurred three years prior on the 11th hour of the 11th day of the 11th month of 1918.
The procession from the Capitol to Arlington included several military units to include those from nine allied nations as well as nurses who served in France, while Gen. John Persing, who commanded the American forces in Europe during the war, walked behind the horse-drawn funeral caisson.
Honors rendered that day included the presentation of the Medal of Honor by President Harding. Four military chaplains (to include a rabbi) participated in the funeral service. A national two-minute silence augmented the thousands in attendance. Flowers and wreaths were massed while salutes were fired. Pershing deposited some soil from France into the tomb. The chief of the Crow Nation rested his coup stick across the tomb as a tribute to the fallen and presented his war bonnet.
Today, Armistice Day is known as Veterans Day and the Tomb has had other Unknowns interred to include the World War II and Korean War Unknowns in 1958 and 1984, respectively. Guarded originally by details from nearby Fort Myer and, since 1948, by an elite group of Sentinels provided by the 3rd Infantry Regiment “The Old Guard,” the Tomb has been reverently secured 24 hours a day, 365 days a year, no matter the weather.
In honoring the 100th anniversary of the interment of the WWI Unknown Soldier, for the first time in a century, the public has been allowed entrance to the normally off-limits Tomb of the Unknown Soldier Plaza this week to place flowers near the memorial.
On Veterans Day, Nov. 11, the public is invited to observe a joint full honors procession, meant to replicate elements of the World War I Unknown Soldier’s 1921 funeral procession. Following this, there will be a combined services flyover of the cemetery and the National Mall in conjunction with the Armed Forces Full Honors Wreath Ceremony to honor the Unknowns and the centennial of the Tomb, set for 11 a.m.
For more information on the Tomb, here is a tour of the display room in the Tomb of the Unknown Soldier Exhibit at Arlington National Cemetery.
As for Olympia, she lingered on in Naval service, decommissioned in 1922 and preserved as a relic/floating office space at the Philadelphia Naval Shipyard until 1957 when she was stricken and transferred to a local non-profit for use as a civilian-run museum ship, a task she continues to perform today.
A lead plaque was installed on the cruiser’s hatch in the 1920s where the Unknown had rested for the trip from France but, sadly, is not on the ship today, being removed when she was decommissioned. However, it is preserved at the NMUSN.

On this date, November 9th, 1921, cruiser OLYMPIA arrived at the Washington Navy Yard carrying the Unknown Soldier of the first World War, having brought the casket across the stormy Atlantic Ocean from Le Havre, France. It was at this time that the casket was transferred from the hands of the U.S. Navy aboard OLYMPIA to the waiting Army contingent, who would then carry the body to Arlington National Cemetery for interment where he rests at the Tomb of the Unknowns today.
Sentinels, assigned to the 3d U.S. Infantry Regiment (The Old Guard), stand guard at the Tomb of the Unknown Soldier at Arlington National Cemetery, Va., Jan. 22, 2016, as a record breaking snow storm hits the Washington, D.C. area. The Tomb Guards maintain a constant vigil at the Tomb no matter the weather conditions and has done so in an unbroken chain ever single second of the past 48 years.
