The Legio II, Sabina was a Roman military unit of the late Republican era, which may have been formed by Julius Caesar in the year of the consulate of 48 BC and coincide, in this case, with the Legio II. Enlisted to fight against Pompey, they took part in the subsequent Battle of Munda of 45 BC. Alternatively it could be the Legio II, formed by the consul, Gaius Vibius Pansa in 43 BC and recruited in Sabina, hence its nickname. If this theory is true, than it probably participated in the subsequent battle of Philippi of 42 BC on the side of the triumvirate, Octavian and Marc Antony. After the defeat of the Republicans, Legio II swore allegiance to Octavian and with the same remained until the battle of Actium of 31 BC, after which it seems to have been dissolved in the years between 30 and 14 BC (sent on leave were between 105,000 and 120,000 veterans and some of its soldiers may have been integrated into the new Legio II Augusta.
The legion participated in the Roman conquest of Britain in 43. Future emperor Vespasian was the legion's commander at the time, and led the campaign against the Durotriges and Dumnonii tribes. Although it was recorded as suffering a defeat at the hands of the Silures in 52, the II Augusta proved to be one of the best legions, even after its disgrace during the uprising of queen Boudica, when its praefectus castrorumPoenius Postumus, who was then its acting commander, contravened Suetonius' orders to join him and so later committed suicide. After the defeat of Boudica, the legion was dispersed over several bases; from 66 to around 74 it was stationed at Glevum, and then moved to Isca Augusta, building a stone fortress that the soldiers occupied until the end of the 3rd century. The legion also had connections with the camp at Alchester in Oxfordshire; stamped tiles record it in the 2nd century at Abonae on the tidal shore of the Avon.
In his fantasy novel Grail, the author Stephen R. Lawhead states that the legion was ensnared by the black magic of the witch Morgan le Fay, doomed to perpetually wander the mists of Lyonesse.
Lindsey Davis' character Marcus Didius Falco and his best friendLucius Petronius Longus both served in the legion during Boadicea's Revolt in AD 60/61, while they were teenagers. Marcus and Lucius only refer to their service in asides, due to the bad memories of the Revolt and the boredom in a cold, unfriendly country. The scenes of carnage and destruction in Londinium left a deep impression on both of them, with neither keen to return to Brittania. Their internal references also hint that their disgraced prefect, Postumius, did not commit suicide, but instead was executed by the legionaries for his refusal to march to Governor Suetonius's aid during the Revolt, but the legionaries swore an oath never to speak of this to outsiders. Novels that most directly refer to their service in Britain are The Silver Pigs, The Iron Hand of Mars, A Body in the Bath House and The Jupiter Myth.
It is also the Legion in which OptioQuintus Licinius Cato and Centurion Lucius Cornelius Macro serve during the first five books of the Eagles of the Empire series by Simon Scarrow. The books also cover Vespasian's career as commander of the legion and the invasion of Britain.
The story of the legion's role in Boadicea's Revolt and the subsequent suicide of its acting commander features in Imperial Governor, George Shipway's 1968 novel about Gaius Suetonius Paulinus.
The II Legion features in Adrian Goldsworthy's novel series, beginning with Vindolanda, about a fictitious centurion of the legion.
