Following Libya's withdrawal from southern Chad in 1982, Habré's Armed Forces of the North (FAN) took control of the entirety of Chad with the exception of the Tibesti, where Goukouni remained with his Libyan-backed Government of National Unity (GUNT) forces. Goukouni 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.
