Legio X Equestris

Founded by Julius Caesar around 61 (or 59) BC, during his time as governor of Hispania, Legio X Equestris was Caesar's first order. Like the other legions of Caesar made famous in the ancient Roman Legions, the Legion X Equestris has a bull as its symbol. However, the Legion X Equestris was Caesar's favorite legion and his most trusted legion. The Legion X Equestris accompanied the famous general when he invaded Gaul in 58 BC. It also played an important role in the civil war against Pompey, present at Ilerda and Pharsalus. The legion's most famous moment was at the Battle of Munda, the final battle of the conflict. After Caesar personally entered the fray, fighting alongside his favorite soldiers and encouraging them, Legio X Equestris repelled the Pompeians, winning the day and the war.

After Caesar's assassination, Legion X Equestris joined Mark Antony in his Parthia campaign. The legion also sided with him in the war with Octavian. After Actium, the Legion X Equestris was among the armies that surrendered to the emperor. However, after their uprising, the soldiers of the Legion X Equestris were punished, with the legion's name stripped. The Legion X Equestris was later merged with the Legion X Gemina (meaning "twins"), continuing to serve in the imperial Roman army as a new unit. During its existence, the Legio X Equestris was stationed on the Danube and Rhine rivers, defending the border against German invaders. The last mention of the legion is from the beginning of the fifth century when it was located at Vindobona (present-day Vienna).
