Legio II Adiutrix ("Second Legion, the Rescuer") was a legion of the Imperial Roman army founded in AD 70 by the emperor Vespasian (r. 69–79), originally composed of Roman navy marines of the classis Ravennatis. There are still records of II Adiutrix in the Rhine border in the beginning of the 4th century. The legion's symbols were a Capricorn and Pegasus.
