Passage: The pattern of the war delineated itself in 1978, with the Libyans providing armour, artillery and air support and their Chadian allies the infantry, which assumed the bulk of the scouting and fighting. This pattern was radically changed in 1986, towards the end of the war, when most Chadian forces united in opposing the Libyan occupation of northern Chad with a degree of unity that had never been seen before in Chad. This deprived the Libyan forces of their habitual infantry, exactly when they found themselves confronting a mobile army, well provided now by the United States, Zaire and France with anti-tank and anti-air missiles, thus cancelling the Libyan superiority in firepower. What followed was the Toyota War, in which the Libyan forces were routed and expelled from Chad, putting an end to the conflict.
