Last Campaigns in Samnium
While these events were passing, the war had not been suspended in Samnium. The campaign of 443 was confined like the preceding to the besieging and storming of several strongholds of the Samnites; but in the next year the war took a more vigorous turn. The dangerous position of Rullianus in Etruria, and the reports which spread as to the annihilation of the Roman army in the north, encouraged the Samnites to new exertions; the Roman consul Gaius Marcius Rutilus was vanquished by them and severely wounded in person. But the sudden change in the aspect of matters in Etruria destroyed their newly kindled hopes.
Lucius Papirius Cursor again appeared at the head of the Roman troops sent against the Samnites, and again remained the victor in a great and decisive battle (445), in which the confederates had put forth their last energies. The flower of their army--the wearers of the striped tunics and golden shields, and the wearers of the white tunics and silver shields--were there extirpated, and their splendid equipments thenceforth on festal occasions decorated the rows of shops along the Roman Forum. Their distress was ever increasing; the struggle was becoming ever more hopeless. In the following year (446) the Etruscans laid down their arms; and in the same year the last town of Campania which still adhered to the Samnites, Nuceria, simultaneously assailed on the part of the Romans by water and by land, surrendered under favourable conditions.
