Before going to war against the Numidians, Marius trained his soldiers extensively and modified Roman battle tactics. He also made his soldiers professionals by removing the property qualification. Even though this new motivated army won a series of impressive battles in Numidia, Marius was unable to defeat Jugurtha until the young prince was captured by a treachery in 104. His capture was arranged by Marius’ deputy Lucius Cornelius Sulla.
