 Commandant Galopin had been sent to the north of Chad to negotiate the release of Françoise Claustre, and her fellow hostages, by the French and Chadian governments.However, it has been alleged that he had a second mission, which was to encourage dissent among the rebels, and it was for this, together with his involvement in the interrogation of captured rebels using torture, that he had been condemned.The extent of Hissène Habré's involvement in his death is also disputed.
