Voulet-Chanoine mission

The Voulet–Chanoine Mission or Central African-Chad Mission (French: mission Afrique Centrale-Tchad) was a French military expedition sent out from Senegal in 1898 to conquer the Chad Basin and unify all French territories in West Africa. This expedition operated jointly with two other expeditions, the Foureau-Lamy and Gentil missions, which advanced from Algeria and Middle Congo respectively. With the death of the Muslim warlord Rabih az-Zubayr, the greatest ruler in the region, and the creation of the Military Territory of Chad in 1900, the Voulet–Chanoine Mission had accomplished all its goals. However, this success followed numerous misadventures, including the refusal of the expedition commander and his second-in-command to follow orders from France, and their subsequent murder at the hands of their soldiers. In the end, only one of the nine Europeans leading the mission, Paul Joalland, was to reach Chad.

The Voulet–Chanoine Mission to Lake Chad set out from Dakar in November 1898, moving through French Sudan (modern Mali). It was composed of 50 Senegalese Tirailleurs, 20 spahis (both units recruited in West Africa) and 30 interpreters, but the bulk was formed by 400 auxiliaries and 800 porters that were pressed into service. The force was directed by nine European officers, the two commanders, the artillery expert lieutenant Paul Joalland, Lt. Louis Peteau, Marine-Lt. Marc Pallier, the medical officer Dr. Henric and three NCOs. The expedition was fully armed with artillery, machine guns, hundreds of rifles and millions of rounds of ammunition.
