Editing Battle of Ad Decimum (section)

===Prelude===
The [[Vandal Kingdom]] in North Africa was ruled by King [[Hilderic]]. His reign was noteworthy for the kingdom's excellent relations with the [[Byzantine Empire]] ruled by Emperor [[Justinian I]].<ref name=":0">{{Cite book|url=https://archive.org/details/belisariuslastro00ianh|title=Belisarius : the last Roman general|last=Hughes, Ian (Historian)|date=2009|publisher=Westholme|isbn=978-1594160851|location=Yardley, Pa.|oclc=294885267|url-access=registration}}</ref> Procopius writes that he was "a very particular friend and guest-friend of Justinian, who had not yet come to the throne",<ref name=":5" /> noting that Hilderic and Justinian exchanged large presents of money to each other. Hilderic allowed a new Chalcedonian bishop to take office in the Vandal capital of Carthage, and many Vandals began to convert to the Chalcedonians, to the alarm of the Vandal nobility. Hilderic rejected the [[Arianism|Arian]] Christianity that most Vandals followed. However, in 531,<ref>J-J.Norwich "A short history of Byzantium", Penguin Books</ref> Hilderic was overthrown by his cousin [[Gelimer]], a popular military commander who had commanded successfully against the Moors.<ref name=":0" /> Gelimer began persecuting the non-Arian population, and many fled to the Byzantine Empire. Justinian sent Byzantine general [[Belisarius]] to reconquer the former Roman province of North Africa. On Midsummer Day 533 the expedition set off. It consisted of 5,000 Byzantine cavalry and twice as many infantry and some additional units but their number and composition is not named by the primary sources.<ref name=":0" /> They travelled in a fleet of 500 transports,<ref name=":0" /> escorted by ninety-two [[dromons]].<ref name=":1">{{Cite book|title=The Generalship of Belisarius|last=Brogna|first=Anthony|publisher=Hauraki Publishing|year=2015}}</ref> Once the fleet arrived safely in North Africa, the Byzantine army disembarked and marched up the coast to [[Carthage]], the Vandal capital, the ships keeping pace with the army offshore.<ref name=":0" /> Contact with the fleet was lost however when it had to sail round [[Cape Bon]].<ref name=":0" />
