The Battle of Maaten al-Sarra was a battle fought between Chad and Libya on September 5, 1987, during the Toyota War. The battle took the form of a surprise Chadian raid against the Libyan Maaten al-Sarra Air Base, meant to remove the threat of Libyan airpower, that had already thwarted the Chadian attack on the Aouzou Strip in August. The first clash ever held in Libyan territory since the beginning of the Chadian–Libyan conflict, the attack was fully successful, causing a high number of Libyan casualties and low Chadian casualties, also contributing to the definitive ceasefire signed on September 11 among the warring countries.
