Hippo Regius
Around July–August 431, Genseric raised the siege of Hippo Regius, which enabled Bonifacius to retreat from Hippo Regius to Carthage, where he was joined by Aspar's army. Some time in the summer of 432, Genseric soundly defeated the joint forces of both Bonifacius and Aspar, which enabled him to seize Hippo Regius unopposed. Genseric and Aspar subsequently negotiated a peace treaty of some sorts. Upon seizing Hippo Regius, Genseric made it the first capital of the Vandal kingdom.
