On this date in 1975, French Major Pierre Galopin was executed by Chad rebel Hissène Habré.
Galopin (English Wikipedia entry | French) had been dispatched to the former French colony to negotiate the release of two French nationals* seized as hostages by Habre’s Command Council of the Armed Forces of the North (CCFAN).
You’ll never guess it: CCFAN also took Galopin hostage.**
CCFAN tried to leverage its new captive into an arms trade. When France dragged its feet, the Chadians terminated the negotiation by having Galopin condemned by a “revolutionary tribunal” and hanged to a roadside tree.
Habre would eventually take power as President of Chad in 1982, and was subsequently welcomed on state visits to the former mother country — much to the disgust of those who remembered the Frenchman sacrificed to his ambitions. Galopin was hardly the last man to be so distinguished: as of this writing, Habre is serving an eternal prison sentence in neighboring Senegal for crimes against humanity committed during his eight years ruling Chad.
* Archaeologist Françoise Claustre and development worker Marc Combe. (A third hostage, West German doctor Christoph Staewen, had also been taken, but had quickly been ransomed by his government.) Combe escaped in 1975. Claustre was not released until 1977.
** CCFAN was also riven by a major internal division that by 1976 would split the movement into two rival organs. It has long been murky (French-language pdf here) just whose interest within CCFAN was best served by the hostile course of events.
