4.  The news of this disaster excited at Rome an alarm greater than suited the importance of the affair; for, as if the army had been destroyed, a justitium was proclaimed, guards mounted at the gates, and watches set in every street:  and armour and weapons were heaped on the walls.  All the younger citizens being compelled to enlist, the dictator was ordered to join the army.  There he found every thing in a more tranquil state than he expected, and regularity established through the care of the master of the horse, the camp removed to a place of greater safety, the cohorts, which had lost their standards, left without tents on the outside of the ramparts and the troops ardently impatient for battle, that their disgrace might be the sooner obliterated.  He therefore immediately advanced his camp into the territory of Rusella.  Thither the enemy also followed, and although, since their late success, they entertained the most sanguine hopes from an open trial of strength, yet they endeavoured to circumvent the enemy by a stratagem which they had before practised with success.  There were, at a small distance from the Roman camp, the half-ruined houses of a town which had been burnt in the devastation of the country.  A body of troops being concealed there, some cattle was driven on, within view of a Roman post, commanded by a lieutenant-general, Cneius Fulvius.  When no one was induced by this temptation to stir from his post, one of the herdsmen, advancing close to the works, called out, that others were driving out those cattle at their leisure from the ruins of the town, why did they remain idle, when they might safely drive them through the middle of the Roman camp?  When this was interpreted to the lieutenant-general, by some natives of Caere, and great impatience prevailed through every company of the soldiers, who, nevertheless, dared not to move without orders, he commanded some who were skilled in the language to observe attentively, whether the dialect of the herdsmen resembled that of rustics or of citizens.  When these reported, that their accent in speaking, their manner and appearance, were all of a more polished cast than suited shepherds, “Go then,” said he, “tell them that they may uncover the ambush which they vainly conceal, that the Romans understand all their devices, and can now be no more taken by stratagem than they can be conquered by arms.”  When these words were heard, and carried to those who lay in ambush, they immediately arose from their lurking place, and marched out in order into the plain which was open to view on every side The lieutenant-general thought their force too powerful for his small band to cope with.  He therefore sent in haste to Valerius for support, and in the mean time, by himself, sustained the enemy’s onset.
