Hello Einbauschrank,
I have visited Louis-Marcel-Alexandre Boudet's personnel file in the military archives in Vincennes.
His bio and portrait are online on my website: http://www.ecole-superieure-de-guerre.fr/louis-marcel-alexandre-boudet.html
Boudet left the Army in 1910, soon after he was wounded during the Abbeys uprising, Then he became a colonial administrator in Ivory Coast . As a reserve officier, he was mobilized in the Senegalese troops in August 1914, and was further (1917) a staff officer in the "Armée française d'Orient".
Demobilized in 1919, he disappeared in the wreck of the liner Afrique, on 13 January 1912, as he was going back to Africa.
Sorry, the bio is in French language ; however, please, tell me if you have difficulties for reading.
Best regards.
François
