Instead of solving the minorities problems by informations and dialogue, the Government left the Army with the fight against the guerrilla, which were formed by these same minorities, much more trained, motivated and supervised, while the Indo-Chinese Federation Army, contrary to their opponents, were understaffed and could not meet all local needs.
