Legio XIV Gemina

Legio quarta decima Gemina ("The Twinned Fourteenth Legion") was a legion of the Imperial Roman army, levied by Julius Caesar in 57 BC. The cognomen Gemina (Twinned) was added when the legion was combined with another understrength legion after the Battle of Actium. The cognomen Martia Victrix (martial and victorious) was added sequentially following their service in the Pannonian War c. AD 9 and the defeat of Boudicca in AD 61. The emblem of the legion was the Capricorn, as with many of the legions levied by Caesar.

The XIV G.M.V was first raised by Caesar in Cisalpine Gaul during his raids into, and conquest of, Gaul. Following its first destruction under Caesar it was immediately reconstituted. Their enlistment term was for 16 years, as per the other Republican legions (though Augustus raised that to 20). For years after the Massacre at Atuatuca carried out by the Eburones under Ambiorix together with Cativolcus they were viewed as an unlucky legion, but survived due to the efforts of their Aquilifer, Lucius Petrosidius. They were frequently left behind to guard the camp during battles and raids.
