Pompeius the Younger's head was then cut off and brought to Hispalis, where it was displayed to the local populace. Meanwhile, the Lusitanians who had escaped the battle rallied many of their tribal members and attacked the forces of Gaius Didius, who had set up a camp near the coast. Provoking Didius to sally out from his camp by setting fire to his landed ships, the Lusitanians ambushed and killed him and many of his men. Those who survived fled to their remaining ships and escaped to the sea. After Munda and Gnaeus Pompeius' death, Julius Caesar believed the Pompeians to be completely defeated in Spain, and consequently left only few forces there to mop up the remaining resistance when returning to Rome. Unlike his older brother, however, Sextus Pompey successfully evaded the Caesarian pursuers and actually rebuilt the Pompeian armies. By the time Caesar was assassinated in 44 BC, he had reconquered most of southern Spain for the Pompeian cause.
