This mountain fastness formed the citadel from which the Samnites issued in conquering excursions over the surrounding country, and enabled them in time to extend their dominion far and wide, and to rival Rome in the width and importance of their state. Thus Rome and Samnium approached each other step by step, and the time inevitably came when they were to join issue in war.
Three wars took place between the Romans and the Samnites. In the first of these Valerius Corvus (the origin of whose name of Corvus we have already told) led the Roman army to victory. In honor of this victory Rome received from Carthage (with which city it was to engage in a desperate contest in later years) a golden crown, for the shrine of Jupiter in the Capitol.
In 329 B.C. Rome finally overcame the Volscians, with whom they had been many years at war, and three years afterwards war with the Samnites was again declared. The latter were invading Campania, in which country lay the volcano of Vesuvius and the city of Naples. Rome came to the aid of the Campanians, and a war began which lasted for more than twenty years.
Of this war we have but one event to tell, that in which Rome suffered the greatest humiliation it had met with in its entire career, the famous affair of the Caudine Forks. It was in the fifth campaign of the war that this event took place. Two Roman armies had marched into Campania and threatened the southern border of Samnium, which the Samnite general Pontius was prepared to defend. His force occupied the passes which led from the plain of Naples into the higher mountain valleys; but he deceived the Romans by spreading the report that the whole Samnite army had gone to Apulia, where they were besieging the city of Luceria. His purpose was to lure the Romans into these difficult defiles under the impression that the Samnites were trusting to the natural strength of their country for its defence.
The trick succeeded. The Roman consuls believed the story, and, in their haste to go to the aid of their allies in Apulia, chose the shortest route, that which led through the Samnian hills. The absence of the Samnite army would enable them, they thought, to force their way through Samnium without difficulty; and, blinded by their false confidence, the consuls recklessly led their men into the fatal pass of Caudium.
This pass was a narrow opening in the outer wall of the Apennines, which led from the plain of Campania to Maleventum. To-day it is traversed by the road from Naples to Benevento, and is called the valley of Arpaia. In the past it was famous as Caudium.
Into this defile the Romans marched between the rugged mountain acclivities that bounded its sides, and through the deep silence that reigned around. The pass seemed utterly deserted, and they expected soon to emerge into a more open valley in the interior of the hills.
But as they advanced the pass contracted, until it became but a narrow gorge, and this they found to be blocked up with great stones and felled trees. Brought to a halt, the troops stood gazing in dismay and dread on these obstacles, when suddenly the silence was broken, loud war-cries filled the air, and armed Samnites appeared as if by magic, covering the hills on both flanks, and crowding into the pass in the rear.
The Romans were caught in such a trap as that from which Cincinnatus had rescued a Roman army many years before. But there was here no Cincinnatus with his stakes, and they were far from Rome. The entrapped army made a desperate effort to escape, attacking the Samnites in the rear, and seeking to force their way up the rugged surrounding hills. They fought in vain. Many of them fell. The Samnite foe pressed them still more closely into the rocky pass. Only the coming of night saved them from total destruction.
But escape was impossible. The gorge in front was completely blocked up. The pass in the rear was held by the enemy in force. The flanking hills could hardly have been climbed by an army, even if they had not been occupied. No resource remained to the Romans but to encamp in the broader part of the narrow valley, and there wait in hopeless despair the outcome of their folly.
