These commanders carried out the enrolment with unusual strictness, and led an exceptionally fine army into Samnium. But although they were on hostile territory, they exercised as little caution in choosing the site for their camp as though the enemy had been at a great distance.
Suddenly the Samnite legions advanced with such boldness that they encamped with their rampart close to the Roman outposts.
The approach of night prevented them from making an immediate attack; they disclosed their intention as soon as it grew light the next morning. The Dictator saw that a battle was nearer than he expected, and he determined to abandon a position which would hamper the courage of his men Leaving a number of watch-fires alight to deceive the enemy, he silently
withdrew his troops, but owing to the proximity of the camps his movement was not unobserved. The Samnite cavalry immediately followed on his heels but refrained from actual attack till it grew lighter, nor did the infantry emerge from their camp before daybreak.
As soon as they could see, the cavalry began to harass the Roman rear, and by pressing upon them where difficult ground had to be crossed, considerably delayed their advance.
