To reestablish their supply lines and retake the towns of Bardaï, Zouar and Wour, the Libyans sent a task-force of 2,000 troops with T-62 tanks and heavy support by the Libyan Air Force into the Tibesti. The offensive started successfully, expelling the GUNT from its key strongholds, also through the use of napalm. This attack ultimately backfired, causing the prompt reaction of Habré, who sent 2,000 FANT soldiers to link with the GUNT forces. Also Mitterrand reacted forcefully, ordering a mission which parachuted fuel, food, ammunition and anti-tank missiles to the rebels, and also infiltrated military personnel. Through this action, the French made clear that they no longer felt committed to keep south of the Red Line, and were ready to act whenever they found it necessary.
