in
Bangkok is a memorial to the
Thai soldiers killed on the Western Front in World War I. It's not widely known that
Thailand deployed an expeditionary force to fight on the side of the Western powers during the Great War in Europe 1914 - 1919.

At the northern edge of Sanam Luang near the National Gallery, there's a neat garden with well trimmed hedges. In the center stands a white four-sided structure topped with a chedi-like spire. This is the Monument to the Expeditionary Force with the names of the dead inscribed on the sides; 9 on the western face and 10 on the eastern face. Some of them were just 21.

In the reign of King Vajiravudh or King Rama VI, World War I broke out between Britain/France and the Central Powers made up of Austria-Hungary, Bulgaria, Germany and the Ottoman Empire (Turkey). Like the USA,
Thailand was initially neutral.
