In the First World War, Kleuap Kaysorn chronicled Thai soldiers' support for the US Army in the Maas-Argonne offensive. The warm relationship between the Thais and the Americans shines through. Eye-opening documents reveal why King Rama VI of Siam joined the Allies, sensitive to atrocities against civilians. With courage and intelligence, he foresaw a grim price if Imperial Germany controlled more of Asia. The book studies the horrific Spanish Flu virus pneumonia pandemic with echoing lessons. New appraisals of the characters of Rama VI and Kaiser Wilhelm II are made from the King's own letters, speeches and poetry, with chilling lost quotes on racism and murder from the Kaiser. Recently-discovered pictures and artefacts from the time place the reader everywhere the Thai soldiers went.
