It is unknown if he took part in the Battle of the Catalaunian Plains where his father died, nor is it known what he did during the short reign of his eldest brother Thorismund (451–453).
But it is somewhat known that Frederic accompanied his brother Theodoric II on multiple campaigns possibly from 456 to 463 in Gaul and Hispania after Theodoric's accession to the throne in 453 as the Goths expanded their influence in the crumbling Western Roman Empire after the deaths of Aetius (21 September 454) and Valentinian III (16 March 455).
All that is recorded of him is that he took part in the Battle of Aurelianum (463) against the Magister Militum of Gaul Aegidius.
His death had serious repercussions in the Kingdom as Theodoric II would be murdered in early 466 by their youngest, but most ambitious brother Euric.
