January 15, 1970

Official surrender papers signed by Biafran General Philip Effiong, deputy to Ojukwu who had fled to the Ivory Coast a few days prior

Four days after Nigerian forces captured the final Biafran stronghold of Owerri, Biafran troops surrendered. Members of the Biafran leadership held their final meeting in which Ojukwu declared that he was going abroad “in search of peace.” He turned control of the presidency over to vice president Philip Effiong and control of the military to Major Joseph Achuzie. Ojukwu then left from Uli airstrip and flew to Cote d’Ivoire.

After Ojukwu’s departure, Effiong immediately called a ceasefire. On January 12, Effiong, Achuzie, and other prominent members of the Biafran military and leadership broadcast their surrender to the Nigerian forces.
