Rome, meanwhile, was increased by Alba's downfall. The number of citizens was doubled, the Caelian Hill was added to the City, and, that it might be more thickly settled, Tullus chose it for the site of the king's house and from that time onwards resided there.
The chief men of the Albans he made senators, that this branch of the nation might grow too. Such were the Julii, the Servilii, the Quinctii, the Geganii, the Curiatii, and the Cloelii. He also built, as a consecrated place for the order he had enlarged, a senate-house, which continued to be called the Curia Hostilia as late as the time of our own fathers.1
And that all the orders might gain some strength from the new people, he enrolled ten squadrons of knights2
from among the Albans, and from the same source filled up the old legions and enlisted new ones.
Confiding in these forces, Tullus declared war on [p. 109]
the Sabines, a nation second only at that time to3
the Etruscans in its wealth of men and arms. On either side there had been aggressions and refusals to grant satisfaction.
Tullus complained that at the shrine of Feronia, in a crowded fair, Roman traders had been seized; the Sabines alleged that, before this, refugees from their country had fled to the grove of sanctuary, and had been detained in Rome.
These were put forward as the causes of war. The Sabines, not forgetting that a portion of their own forces had been settled in Rome by Tatius and that the Roman state had recently been further strengthened by the addition of the Alban people, began themselves to look about for outside help.
Etruria was close by, and the nearest of the Etruscans were the Veientes. There the resentment left over from the wars was the strongest incentive to revolt, and procured them some volunteers; while with certain vagrant and poverty-stricken plebeians even the prospect of pay was effectual. Official aid there was none, and the Veientes (for there is less to surprise us in the others) held firmly to the truce they had agreed upon with Romulus.
While preparations for war were making on both sides with the greatest energy, and success appeared to hinge upon which should first take the field, Tullus anticipated his enemies and invaded the Sabine country.
A desperate battle was fought near the Silva Malitiosa,4
where, owing partly, it is true, to the strength of their infantry, but most of all to their newly augmented cavalry, the Roman army gained the mastery.
The cavalry made a sudden charge; the ranks of the Sabines were thrown into disorder, and from that moment were unable, without heavy loss, either to hold their own in the fight or to extricate themselves by a retreat.
