Time had passed since Marcellus and his soldiers first entered Gaul, enough time for them to finally enter the Pyrenees. Aside from a few small conflicts with brigands and barbarians, they arrived at their destination with few losses. The soldiers of Marcellus legions were high in morale as they entered the mountain range and cut off Constantine's ability to escape.
The plan was simple: dispatch a messenger to the allied troops in Hispania, informing them to begin their counterattack so that they can push the usurper and his armies back to the mountains where they would be caught between Marcellus' troops and those of Hispania. Thus, for the time being, Marcellus had established a camp at the foothills of the mountains where his army lie in wait for the enemy.
