The decisive confrontation between the Libyan-FAP forces and the Chadian regular forces took place at Faya-Largeau, the capital of the BET. The city, defended by 5,000 Chadian soldiers, fell on 18 February after sharp fighting to a force of 2,500 rebels, supported by possibly as many as 4,000 Libyan troops. The Libyans do not seem to have directly participated in the fighting; in a pattern that was to repeat itself in the future, the Libyans provided armor, artillery and air support. The rebels also were much better armed than before, displaying Strela-2 surface-to-air missiles.
