Majorian
During his reign, Majorian was able to secure several succesful campaigns in Gaul and Hispania reconquering much of both provinces and bringing it back under Roman Control. In 460 Majorian went to Hispania and ordered to build as massive fleet for preperations for an invasion of Africa, but before he was able to put his plans into action, his redied fleet was burned most of it destroyed and only leaving a few warships in a good state. After the incident, Majorian abandons his plans for a possible reconquest of Africa and instead focused on retaking Gaul and Hispania instead.
