Ok checked those videos most of them First of all their dates are unverified and certainly unverifiable by me Most concern the formation of the Expeditionary Force under Leclerc as I already explained this did not arrive in Indochina before at the earliest late August Some mention the formerly Vichy French forces withdrawn to China after March  it should be noted that those forces were small and withdrawing not reconquering the territory Other videos again claim to show fighting against the Japanese yet all they show is Japanese POWs labouring for the French Expeditionary Corps oh and of course Vietnamese civilians seemingly detained by said French forces that material clearly shows events of the early phase of Leclercs arrival he didnt stay long that is to say a period between the Viet Minhs declaration of Vietnamese Independence and the Civil War In short none of these videos show any material concerning a French reconquest of Indochina against Japanese occupiers
