The Acting Council General of British Nigeria, James Phillips, and his party of 250 Nigerian soldiers are ambushed and killed by forces of the Kingdom of Benin. Beninese scouts have learned that he is on a secret mission to kill the Oba (king) of Benin, and take possession of the country. Phillips has disguised his African soldiers as porters, but his plan is already known. Determined to take Benin as a possession one way or another, Britain will use Phillips' death as an excuse to launch a full-scale war, destroy Benin City, and arrest the Oba.
