Gaius Octavius
Legio X Fretensis ("Tenth legion of the Strait") was a legion of the Imperial Roman army. It was founded by the young Gaius Octavius (later to become Augustus Caesar) in 41/40 BC to fight during the period of civil war that started the dissolution of the Roman Republic. X "Fretensis" is then recorded to have existed at least until the 410s.
