The Tombs of the Unknown Soldiers contain the remains of a dead soldier who is unidentified. These remains are considered impossible to be identified, and so serve as a symbol for all of a country's unknown dead wherever they fell in the war being remembered. The anonymity of the entombed soldier is the key symbolism of the monument; it could be the tomb of anyone who fell in service of the nation, and therefore serves as a monument symbolizing all of the sacrifices, for this reason it became a war memorial.

The idea of a Tomb of the Unknown Warrior was born in 1916 from the Reverend David Railton, who, while was serving as chaplain to British forces in France, had seen a make-shift grave marked by the written legend 'An Unknown British Soldier'. He wrote to the Dean of Westminster in 1920to convey a remembrance of that scene. 

Selection of the soldier destined for burial in the Nave at Westminster Abbey began in France, where the remains of four unknown British war casualties were exhumed from France and Belgium. The Brigadier General L.J. Wyatt, commander of British troops in France and Flanders, at random selected one to become the Unknown Soldier of the Great War, and two officers placed the body in a coffin and sealed it. 

In November 8 a service was held to commemorate the sacrifice of the Unknown Soldier, officiated by chaplains from the Church of England, the Roman Catholic Church, and the Non-Conformist Churches. 

In November 11, the Unknown Soldier was transported through London's crowd-lined streets and to the west end of the Nave in Westminster Abbey. Following the hymn "Lead Kindly Light", King George V sprinkled soil from the battlefield at Ypres.  So the ritual was very important at national level. Some 1.2million people visited the Abbey during the week after the burial.

In November 18 a temporary stone sealed the grave, inscribed with the words: "A British Warrior Who Fell in the Great War 1914-1918 for King and Country.  Greater Love Hath No Man Than This."

In October 17, 1921 American General John J. Pershing presented the Medal of Honor to the Unknown Soldier of Great Britain.  That Medal of Honor now hangs in a frame on a nearby pillar.

In November 11, 1921, the same date on which the American Unknown Soldier was laid to rest at Arlington National Cemetery. A slab of black Belgian marble became the permanent replacement with an inscription to forever commemorate the Unknown soldier from World War I.

The documents we read have the function of teaching how the ritual of the Unknown soldier was born, increasing understanding of the humanitarian impact of armed conflict, exploring feelings and emotions of people involved in, and affected by, armed conflict and respecting human life and dignity.

To facilitate the divulgation of the history of the memorial, the writers of the texts we read used a simple syntax and language.
