Legio XXI Rapax

After the disaster of the Battle of the Teutoburg Forest, the legion was sent as reinforcements to Germania Inferior, where they shared the base camp of Castra Vetera (Xanten) with V Alaudae.

Along with the rest of the German border army, the XXI Rapax supported its commander, Vitellius, in the Year of the Four Emperors (69) and defeated Othonian forces at the First Battle of Bedriacum.

After that they were sent to Germania Superior, where they shared the castrum (camp) of Moguntiacum (modern day Mainz) with XIV Gemina.

In 89, the legions in Moguntiacum supported their commander, Lucius Antonius Saturninus, in his revolt against emperor Domitian.

[4] In spring of 92, several tribes (probably Marcomanni, Quadi, Jazyges) crossed the Danube and attacked Pannonia, probably destroying XXI Rapax.
