The siege begins in May or June 430.[3] While the bulk of the Vandal army imposed a land and sea blockade, detachments plundered the surrounding province. After 14 months, however, Gaiseric was the one short on supplies. The Vandals lifted the siege, making the ordeal a technical Roman victory. However, Boniface quickly abandoned the city by sea to meet with reinforcements from the eastern empire; the Vandals were able to occupy the town and subsequently defeated the combined Roman forces in a set battle.
