of National Unity (GUNT) forces. Goukouni then established a National Peace Government in Bardaï and proclaimed it the legitimate government of Chad. Habré attacked the GUNT in the Tibesti in both December 1982 and January 1983 but was repelled on both occasions. Although fighting intensified over the next several months, the mountains remained under the control of the GUNT and Libyan forces. By 1986, following a series of military defeats, the GUNT had begun to disintegrate along with relations between Goukouni and Libya. In December, Goukouni was arrested by the Libyans, which spurred his troops to attack Libyan positions in the Tibesti, forcing the Libyans to withdraw. Libya sought to retake Bardaï and Zouar, and 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. The attack ultimately backfired, however, as it resulted in the prompt reaction of Habré, who sent 2,000 soldiers to support the GUNT forces. Although the Libyans were only partially repelled from the Tibesti, the broader campaign was a great strategic victory, as it transformed a civil war into a national war against a foreign invader, stimulating a sense of national unity never before seen in Chad. After a series of defeats in northeastern Chad, Libyan forces withdrew fully from the Tibesti in March 1987. MDJT War Following a decade of relative peace, in late 1997 the Tibesti saw the formation of the Movement for Democracy and Justice in Chad (MDJT), a rebel group opposed to Chadian president Idriss Déby. Numbering around 1,000 fighters at its peak between 2000 and 2001, and financed by Libyan Teda clans and the Libyan government, the MDJT was able to take control of several towns in the Tibesti. Battles with the Chadian National Army (ANT) were particularly violent between 1998 and 2002, resulting in the deaths of between 500 and 850 MDJT rebels and a comparable number of ANT soldiers at locales across northern Chad, including Bardaï. Although civilian casualties were relatively limited, many civilians were killed and injured by landmines, and the war resulted in the displacement of a large portion of the local population. Between 1998 and 2010 the MDJT had established a weak government in the Tibesti region, functionally independent from that of Chad. In 2002, however, weakened by its isolation in the Tibesti and from
