Death came to Labienus in the Battle of Munda, an evenly matched conflict between the armies of Caesar and the sons of Pompey. King Bogud, an ally of Caesar, approached the Pompeians with his army from the rear. Labienus was commanding the Pompeians' cavalry unit at the time, and seeing this, took the cavalry from the front lines to meet him. The Pompeian legions misinterpreted this as a retreat, became disheartened and began to break. Pompeians suffered massive casualties during the rout. This defeat ended Caesar's Civil War. Labienus was killed during the rout. According to Appian, (BC2.105), his head was brought to Caesar. Caesar then dispatched men to locate the body of his old friend, and buried Labienus with full honours.
