with barred "Madagascar", military octagonal cachet "Corresp. D'Armee 2 Fevr 96 K.IAI" (Kompong Iai, Laos), endorsed "Troupes du Mekong", handwritten "Saravane", sent to France, with "Bassac Laos 4 Fevr 96" and "Saigon-Central Cochinchine 13 Fevr" transits, Bellac and Montpellier arrival pmks, v.f. This is the only known usage from Kamthong-IAI, office serving the Bolaven Plateau (an elevated region in southern Laos), letter coming from Saravane Lao (Salavan, today). The "Corresp.D'Armee" cachet is apparently an error as it should have been "Corps Exp." (total franchise). A splendid Colonial military item, unique in every sense
