under what circumstances will umuofia go to war

Ogbuefi Ezuogo, a powerful orator, gives the traditional opening: he faces four different directions, raising a clenched fist, and cries "Umuofia kwenu," to which the men all cry "Yaa!" He greets them this way a fifth time, and then he tells them that men from the neighboring village of Mbaino have killed a girl from Umuofia. This could cause war if restitution is not offered.
