Hippo Regius
Advancing eastwards along the coast, the Vandals were confronted on the Numidian border in May–June 430 by Bonifacius. Negotiations broke down, and Bonifacius was soundly defeated. Bonifacius subsequently barricaded himself inside Hippo Regius with the Vandals besieging the city. Inside, Saint Augustine and his priests prayed for relief from the invaders, knowing full well that the fall of the city would spell conversion or death for many Roman Christians.
