The Battle of Sucro was fought in 75 BC between a rebel army under the command of the Roman rebel Quintus Sertorius and a Roman army under the command of the Roman general Pompey. The battle was fought on the banks of the river Sucro near a town bearing the same name (present day Albalat de la Ribera). It ended indecisively: with Sertorius winning a tactical victory but having to withdraw because Pompey's colleague Metellus and his army were approaching.
