Thai expeditionary force valiantly fought in the European battlefield, but lost 19 veterans during the war. After their return to Thailand on, the ashes of these 19 martyrs saw ceremonial sanctification in the Wat Mahathat nearby. These ashes were then encased in the monument in September 1919. Thus, the edifice is a memorial to these

Today, the white monument sits at the northern edge of Sanam Luang, near the National Gallery of Bangkok. A huge chedi-like spire crowns the four-sided structure. The names of the dead soldiers are engraved on the sides of the monument - 9 on the eastern plane and 10 on the western plane. A well-tended garden, with spruced hedges, surrounds the structure on all sides. People who cherish and remember the selfless sacrifice of these soldiers often visit the place and offer flowers, wreaths and garlands at the site.
