Chibok ambush

The Chibok ambush was an attack of Boko Haram insurgents against a Nigerian Army convoy in the night from 13 to 14 May 2014, as the latter was searching for schoolgirls who had been kidnapped by the Islamist rebels. Even though the Nigerian Army forces managed to extricate themselves from the ambush, the attack seriously affected the morale of the involved soldiers who felt that their leadership was carelessly sacrificing them in the war against the insurgents. As result, elements of the Nigerian Army's 7th Division subsequently mutinied at Maiduguri and almost killed their own commander, "humiliat[ing] the Nigerian military".
