comes domesticorum in return. Civil War with Felix In 427, Bonifatius was recalled to Ravenna by Placidia, but refused the summons. Bonifatius was accused of attempting to form his own empire in Roman Africa at the allegation of Flavius Constantius Felix, who had also been a staunch supporter of Placidia and had been installed as the magister utriusque militiae of the west by Theodosius II. Placidia ordered Felix to send an army to restore the vital province in response. Felix's generals for the expedition included Mavortius, Gallio, and Sanoeces. Mavortius and Gallio led Roman forces proper, while Sanoeces commanded the Hun Foederati troops. Together the three generals laid siege to Bonifatius at Carthage. The three besiegers, however, turned on each other, and Sanoeces and his Huns killed the Romans before he was killed himself, which lifted the siege. When news reached Ravenna, Felix sent the Comes Sigisvultus against Bonifacius, who campaigned with his Goths in Africa for two years. Sigisvultus captured Carthage, but Bonifatius and his Gothic bucellarii continued to campaign in Numidia, where they were allowed to loot the province. Bonifatius also had his daughter baptized by an Arian priest, which caused a falling out between him and St. Augustine. However, Placidia sent an envoy to Bonifatius in 429, from which she learned that a letter had been forged ordering him not to return to Ravenna if summoned. A man named Darius was sent to negotiate a truce between Bonifatius and Sigisvultus, and as a result Bonifatius was restored to Placidia's favor and the civil war ended in time to face the Vandal threat. Campaigns against the Vandals Some sources report that Bonifatius invited the Vandals to Africa, though doubt has been cast on this in recent years. The Vandals crossed near Roman Tingis, and an inscription at Altava dated to 429 mentions the deceased was wounded by a "barbarian" during the Vandal advance across Africa. Their campaign was briefly halted by Darius, who negotiated a brief truce, but Gaiseric quickly resumed. Bonifatius, the African army, and a contingent of supporting Gothic foederati confronted and were defeated by Gaiseric near the city of Calama in 430, after which Bonifatius retreated to the city of Hippo Regius. In May or June of 430, Gaiseric laid siege to the city, and St. Augustine died during the siege, which was finally lifted in July or August of 431. Leaving it at the
