Titus Labienus was one of Julius Caesar’s most experienced legates during the conquest of Gaul and commanded major operations on Caesar’s behalf. When civil war began in 49 BCE, he joined Pompey and became one of Caesar’s most determined opponents.
He fought in Greece, North Africa and Spain and was killed at the Battle of Munda in 45 BCE. The limited evidence leaves his motives open to interpretation.
Simon Turney’s Marius’ Mules XI places Titus Labienus on the Pompeian side as Caesar carries the civil war into Greece and confronts his former allies. In Marius’ Mules XIII, Labienus is one of the principal commanders who regroup with Cato and Metellus Scipio in Africa after Pompey’s death. Marius’ Mules XIV follows the final phase of that opposition in Spain, where Labienus joins Pompey’s sons in trying to build one last army capable of defeating Caesar.
