 In 1981, it was alleged that a senior Nigerian military officer working in the military headquarters stole the Nigerian battle plans for the first Bakassi war with Cameroon and passed it along to French Intelligence who shared it with the Cameroonians.This intelligence coup weakened Nigeria's willingness to fight and forced it to the negotiation table; it was a great humiliation and the NSO had failed to stop it.Umaru Shinkafi in a libel lawsuit he filed against Alhaji Umaru Dikko – the former transport minister in the Shagari cabinet – had alleged that the NSO had indeed informed Shagari about the impending Buhari coup in 1983.
