Three archival photographs recently made public by the French National Library depict men associated with an event taking place in colonial Laos around 1920. However, upon examination of the pictures and textual sources, combined with contemporaneous documents, it turns out that the pictures are actually from Tonkin (colonial northern Vietnam) and may depict Batchai (Pa Chay Vue) a celebrated Hmong messiah in 1918 when he met with colonial authorities in an ultimate negotiation attempt before launching a four-year rebellion. Batchai famously led a violent revolt against Tai and French power in Tonkin and Laos between 1918 and 1921, which has been documented in French military reports. No photograph has ever been found of the rebel leader and his supporters and this find in itself would be of significance, especially for the Hmong diaspora in the West for whom Pa Chay Vue has achieved near-mythical status as a major folk hero. This article examines whether or not this is him; but beyond the simple task of identification, it proposes interpretations for the events that suggest a more complex affair than French military archives have ever been willing to tell, including the hypothesis of an administrative cover up.
