Legio I Adiutrix

Legio prima adiutrix ("Rescuer First Legion"), was a legion of the Imperial Roman army founded in AD 68, possibly by Galba when he rebelled against emperor Nero (r. 54-68). The last record mentioning the Adiutrix is in 344, when it was stationed at Brigetio (modern Szöny), in the Roman province of Pannonia. The emblem of the legion was a capricorn, used along with the winged horse Pegasus, on the helmets the symbol used by I Adiutrix legionaries was a dolphin.

The legion probably originated from the I Classica, a legion levied by Nero among the marines of the Classis Misenensis, but was later completed by Galba. The legion was stationed near Rome.

In the confusing Year of the Four Emperors, the legion fought in Otho's army in the Battle of Bedriacum, where this emperor was defeated by Vitellius The victorious Vitellius ordered the legion transferred to Spain, but by the year 70 it was fighting in the Batavian rebellion.

The city of Moguntiacum (Mainz) is the legion's first known base camp, shared with Legio XIV Gemina, where they attended mainly building activities. In 83, they fought the Germanic wars against the Chatti, a German tribe living across the Rhine, under the command of Emperor Domitian. After that they were transferred to the Danubian army stationed in the Roman province of Pannonia, to fight the Dacians.
