In fact the fighting between the Thais and the French in December 1940 and January 1941 had been brief and inconclusive. Only 59 Thai troops were killed, and the final territorial settlement was imposed on both parties by Japan, which did not want to see a prolonged war between two regional allies at a time when it was preparing to launch a war of conquest in South East Asia. Thailand's gains were less than it hoped for, although more than the French wished to concede. Nevertheless the Thai regime of Field Marshal Plaek Phibunsongkhram decided to celebrate the war as a great victory, and the monument was commissioned, designed and erected within a few months.
