In the later part of the tale there is an expedition to Vientiane which clearly follows one of the routes taken by Bangkok armies during the war against Vientiane in 1827–1828. There are also two military campaigns to Chiang Mai, but here the geography is much less certain. The place names are correct, but temples are located in the wrong town, routes between places make no geographical sense, and other mistakes indicate that the authors had only a hazy idea of the northern region.
