This chapter covers the delicate politics surrounding the integration of Habré’s faction into the CSM. It also describes how French military successes against different rebel factions led to divisions within the northern rebellion, and a split between its main leader, Goukouni Weddeye, and Gaddafi’s Libya. It then covers the fighting which broke out between Habré and Malloum in February 1979. The chapter looks at how the balance of power shifted in favor of Habré as Goukouni’s forces infiltrated the capital and joined Habré’s men. The chapter also analyzes the ambiguous role played by France in facilitating a northern victory, as well as the subsequent debates and recriminations within the French policymaking apparatus. This led to a sharp deterioration in relations between French military officials and diplomats. Meanwhile, by early March 1979, over half of N’Djamena’s population had fled the city towards the south, thus effectively leaving behind an ethnically cleansed capital in the hands of a fragile coalition of Frolinat rebels.
