XV "Apollinaris" is sometimes confused with two other legions with the same number: An earlier unit which was commanded by
Julius Caesarand met its end in North Africa in 49 BC, and a later unit that was present at the Battle of Philippion the side of the Second Triumvirateand then sent east.
Octavianus (later Emperor Augustus) raised XV "Apollinaris" in order to end the occupation of
Sicilyby Sextus Pompeius, who was threatening Rome's grain supply. After the Battle of Actium, the legion was sent to garrison Illyricum, where it probably remained until 6 BC, though it might have seen action in the Cantabrian Wars.
6 BC, "Apollinaris" was part of the huge campaign by Emperor Tiberiusagainst the Marcomannithat was obstructed by a revolt in Pannonia. "Apollinaris" saw a good deal of fighting in the suppression of the revolt. It was most likely this legion that built the Colonia Iulia Aemona. By 9the legion was headquartered in Pannonia, in the town of Carnuntum.
There the unit stayed until sent to Syria and possibly
Armeniaby Neroin 61or 62, these territories newly conquered from the Parthians. After the conclusion of the war with Parthia, the legion was sent to Alexandriabut soon found itself engaged in the fierce fighting of the First Jewish Revolt, capturing the towns of Jotapataand Gamla. It was the Fifteenth that captured the Jewish general later to become famous as the historian Josephus. During this period the legion was commanded by Titus, who would later become Emperor.
After the suppression of the revolt, the legion returned to Carnuntum and rebuilt its fortress. Elements of the XVth fought in the
Dacian Warsalthough the main body of the legion remained in Pannonia.
115, war with Parthia broke out again and the legion was sent to the front, reinforced with elements of the XXX "Ulpia Victrix". The legion fought in Mesopotamia, which was conquered by the Romans. After the conflict was over the unit stayed in the east with a new headquarters at Satalain northeastern Cappadocia, with elements stationed at Trapezuson the Black Sea and at Ancyra, modern-day Ankara. From this base the XVth helped repulse an invasion of Alansin 134.
162, Rome and Parthia were at war once more; the campaign, led by Emperor Lucius Veruswas successful, and the legion occupied the Armenian capital Artaxata. In 175, the general Avidius Cassiusrebelled against Emperor Marcus Aurelius, but the Fifteenth remained loyal and earned the additional title "Pia Fidelis".
The history of the legion after this point involves more conjecture. As a unit stationed in the Middle East, it is almost certain to have taken part in later campaigns against Parthia, including the sack of its capital
Ctesiphonby the Romans in 197, and in wars against the new Sassanidpower that arose in Persia thereafter, though there is no direct record of this. At the beginning of the 5th century, the legion reappears in history: it is still quartered at Satala and Ancyra, though having lost its post at Trapezus somewhere along the way, and is under the command of the " Dux Armeniae".
An inscription possibly relating to this legion was found in a cave in eastern
Uzbekistan, perhaps carved by soldiers captured by the Parthiansand dispatched to their eastern frontier as border guards.
