It took its name from the Bight of Biafra, the Atlantic bay to its south, on the east end of the Gulf of Guinea.

It took a second military tribunal judge to sentence Victor Banjo, because Odumegwu Ojukwu's first military judge stated that there were not enough evidence to convict Victor Banjo of coup charges.  There has been no third party verification of Victor Banjo's involvement in the Nigerian Coup nor Biafran Coup.  His alleged involvement in both coup plots has been based on unsubstantiated hearsay.
