, York With Octavian, whom the Senate later titled
Augustus, established as sole ruler of the Roman world, the legion was sent to Hispania to take part in the large-scale
campaign against the Cantabrians (25–19 BC). The nickname Hispana ("stationed in Hispania") is first found during the reign of Augustus and probably originated at that time. After that the legion was probably part of the imperial army in the
Rhine borderlands that was campaigning against the Germanic tribes. Following the abandonment of the eastern Rhine area (after the disastrous
Battle of the Teutoburg Forest in AD 9), the Ninth was relocated to
Pannonia.
Britain (AD 43 – at least 108) In AD 43 the legion most likely participated in the
Roman invasion of Britain led by the emperor
Claudius and general
Aulus Plautius, because they soon appear amongst the provincial garrison. In AD 50 the Ninth was one of two legions that defeated the forces of
Caratacus. Around the same year, the legion constructed a fort,
Lindum Colonia, now
Lincoln. Under the command of
Caesius Nasica they put down the first revolt of
Venutius, king of the
Brigantes tribe, between 52 and 57. The Ninth suffered a serious defeat at the
Battle of Camulodunum under
Quintus Petillius Cerialis in the rebellion of
Boudica (61), when most of the foot-soldiers were killed in a disastrous attempt to relieve the besieged city of
Camulodunum (Colchester). Only the cavalry escaped. The legion was later reinforced with
legionaries from the Germania provinces. When Cerialis returned as governor of Britain ten years later, he took command of the Ninth once more in a successful campaign against the
Brigantes in 71–72, to subdue north-central Britain. Around this time, they constructed a new fortress at
York (
Eboracum), as shown by finds of tile-stamps from the site. The Ninth participated in
Agricola's invasion of
Caledonia (modern Scotland) in 82–83. According to Tacitus, the legion narrowly escaped destruction when the Caledonians beyond the Forth launched a surprise attack at night on their fort. The Caledonians "burst upon them as they were terrified in their sleep". In desperate hand-to-hand fighting, the Caledonians entered the camp, but Agricola was able to send cavalry to relieve the legion. Seeing the relief force, "the men of the Ninth Legion recovered their spirit, and sure of their safety, fought for glory", pushing back the Caledonians. The legion also participated in the decisive
Battle of Mons Graupius. The last attested activity of the Ninth in Britain is during the rebuilding in stone of the legionary fortress at
York (Eboracum) in 108. This is recorded in an inscribed stone tablet discovered in 1864, now displayed in the
Yorkshire Museum in York.
Germania Inferior (108? – 130?) Several inscriptions attesting IX Hispana have been found in the site of the legionary fortress on the lower
Rhine river at
Noviomagus Batavorum (
Nijmegen, Netherlands). These include some tile-stamps (dated 104–120); and a silver-plated bronze pendant, found in the 1990s, that was part of a
phalera (military medal), with "LEG HISP IX" inscribed on the reverse. In addition, an altar to
Apollo, dating from this period, was found at nearby
Aquae Granni (
Aachen, Germany), erected in fulfillment of a vow, by Lucius Latinius Macer, who describes himself as
primus pilus (chief centurion) and as
praefectus castrorum ("prefect of the camp", i.e. third-in-command) of IX Hispana. (it was commonplace for chief centurions, on completion of their single-year term of office, to be promoted to
praefectus castrorum). The archaeological evidence thus appears to indicate that elements of IX Hispana were present at Noviomagus sometime after AD 104 (when the previous incumbent legion,
X Gemina, was transferred to the Danube) and that IX was probably replaced by a detachment of legion
XXX Ulpia Victrix not long after AD 120. Less clear is whether the whole IX legion was at Nijmegen or simply a detachment. The evidence for the presence of senior officers such as Macer convinced several scholars that the Ninth Legion as a whole was based there between 121 and 130. It may have been both: first a detachment, later followed by the rest of the legion: a
vexillatio Britannica ("British detachment") is also attested at Nijmegen in this period. However, it is unclear whether this detachment was drawn from the IX Hispana (and its attached
auxiliary regiments) alone, or from a mix of various British-based units. == Theories about the Ninth's disappearance ==
