Legio X Equestris

Legio X Equestris (Latin: Tenth Legion "Mounted"), a Roman legion, was levied by Julius Caesar in 61 BC when he was the Governor of Hispania Ulterior. The Tenth was the first legion levied personally by Caesar and was consistently his most trusted. The name Equestris was applied after Caesar mounted legionaries from the Tenth on horses as a ruse in a parley with the German King Ariovistus in 58 BC[dubious – discuss] because he did not trust his Gallic cavalry auxiliaries from the Aedui tribe. Legio X was famous in its day and throughout history, because of its portrayal in Caesar's Commentaries and the prominent role the Tenth played in his Gallic campaigns. Its soldiers were discharged in 45 BC. Its remnants were reconstituted, fought for Mark Antony and Octavian, disbanded, and later merged into X Gemina.
