A force of equal size used to be supplied by the Latins, now, however, they were hostile to Rome. The two armies were drawn up in the same formation, and they knew that if the maniples kept their order they would have to
fight, not only vexilla with vexilla, hastati with hastati, principes with principes, but even centurion with Centurion.
There were amongst the triarii two centurions, one in each army —the Roman, possessing but little bodily strength but an energetic and experienced soldier, the Latin, a man of enormous strength and a splendid fighter —very well known to each other because they had always served in the same Company.
The Roman, distrusting his own strength, had obtained the consuls' permission before leaving Rome to choose his own sub-centurion to protect him from the man who was destined to be his enemy.
This youth, finding himself face to face with the Latin centurion, gained a victory over him.
