[5] Acyl, the FROLINAT's then adjutant chief of staff in charge of the direction and administration of the military, promptly left Faya for Tripoli under the protection of Libyan troops.
[6] Acyl's faction, renamed Democratic Revolutionary Council (CDR) at the beginning of 1979,[7] did not participate in the battle of N'Djamena that erupted in February 1979 and caused the fall of the government in Chad.
[8] For this he was overlooked at the first international peace conference held in March in Kano, in Nigeria, where the main militias agreed to create a government of national unity, which excluded all pro-Libyan factions.
[10] The participants of the conference were unable to reach any agreement on forming the cabinet, and a few weeks later Habré and Goukouni unilaterally agreed with the N'Djamena Accord to exclude Acyl and his allies from the new Transitional Government of National Unity (GUNT).
To defeat his rival Goukouni, probably persuaded by Acyl,[17] on June 15 signed a defense pact with Libya; as a result 7,000 Libyan troops and 7,000 members of the Libyan-raised Islamic Legion were in Chad by the end of 1980, and helped expel Habré from N'Djamena on December 16, after a week of harsh fighting.
[22] Consequently, when, on October 22, French president François Mitterrand proposed to send an Organisation of African Unity peace contingent into Chad to replace the Libyans.
[18] A month later, on July 19, Acyl died in the southwestern town of Laï when he inadvertently stepped backwards into the spinning propellers of his Cessna airplane, a gift from Gaddafi.
