Accordingly the state of the Caeninenses by itself makes an irruption into the Roman territory.
But Romulus with his army met them ravaging the country in straggling parties, and by a slight engagement convinces them, that resentment without strength is of no avail.

He defeats and routs their army, pursues it when routed, kills and despoils their king in battle, and having slain their general takes the city at the first assault.

From thence having led back his victorious army, and being a man highly distinguished by his exploits, and one who could place them in the best light, went in state to the capitol, carrying before him, suspended on a frame curiously wrought for that purpose, the spoils of the enemy's general, whom he had slain, and there after he had laid them down at the foot of an oak held sacred by the shepherds, together with the offering, he marked out the bounds for a temple of Jupiter, and gave a surname to the god: "Jupiter Feretrius," he says, "I, king Romulus, upon my victory, present to thee these royal arms, and to thee I dedicate a temple within those regions which I have now marked out in my mind, as a receptacle for the grand spoils, which my successors, following my example, shall, upon their killing the kings or generals of the enemy, offer to thee." This is the origin of that temple, the first consecrated at Rome.

It afterwards so pleased the gods both that the declaration of the founder of the temple should not be frustrated, by which he announced that his posterity should offer such spoils, and that the glory of that offering should not be depreciated by the great number of those who shared it.

During so many years, and amid so many wars since that time, grand spoils have been only twice gained,[18] so rare has been the successful attainment of that honour.
