Eo rapidius Cerialis, missis in Mediomatricos qui breviore itinere legiones in hostem verterent, contracto quod erat militum Mogontiaci quantumque secum transvexerat, tertiis castris Rigodulum venit, quem locum magna Trevirorum manu Valentinus insederat, montibus aut Mosella amne saeptum; et addiderat fossas obicesque saxorum.
These circumstances moved Cerialis to prompter action: he despatched some officers to the Mediomatrici to direct the legions against the enemy by a more direct route, while he united the troops at Mayence with all the forces that he had brought with him; after a three days march he came to Rigodulum, which Valentinus had occupied with a large force of Treviri. The town was naturally protected by hills or by the Moselle; in addition Valentinus had constructed ditches and stone ramparts.
