Ab urbe condita

The carnage had almost extended to the second line where the standards were stationed when there appeared in the side distance a cloud of dust as though raised by the tread of an immense army. It was Sp. Nautius —some say Octavius Maecius —the commander of the auxiliary cohorts.

They raised a dust out of all proportion to their numbers, for the camp-followers mounted upon the mules were dragging leafy boughs along the ground. At first the arms and standards gradually became visible through the beclouded light, and then a loftier and thicker Cloud of dust gave the appearance of cavalry closing the column.

Not only the Samnites but even the Romans were deceived, and the consul endorsed the mistake by shouting to his front rank so that the enemy could hear: “Cominium has fallen, my victorious colleague is coming on the field, do your best to win the victory before the glory of doing so falls to the other army!”

He rode along while saying this, and commanded the tribunes and centurions to open their ranks to allow passage for the cavalry. He had previously told Trebonius and Caedicius that when they saw him brandish his spear aloft they should launch the cavalry against the enemy with all the force they could.

His orders were carried out to the letter; the legionaries opened their ranks, the cavalry galloped through the open spaces, and with levelled spears charged the enemy's centre. Wherever they attacked they broke the ranks. Volumnius and Scipio followed up the cavalry charge and completed the discomfiture of the Samnites At last the dread of gods and men had yielded to a greater terror, the “linen cohorts” were routed;

those who had taken the oath and those who had not alike fled; the only thing they feared now was the enemy.
