Thus passed the winter. Meanwhile, the Romans had been as active as their enemies. They made the most energetic preparations for war, and with the opening of the spring were in the field. Pyrrhus, who had failed to receive the great army promised him, did not feel strong enough to meet the Roman force. He offered peace and arbitration, but his offers were scornfully rejected. He then sent spies to the Roman camp. One of these was caught and permitted to observe the whole army on parade. He was then sent back to Pyrrhus, with the message that if he wanted to see the Roman army he had better come himself in open day, instead of sending spies by night.
The two armies met at length on the banks of the river Siris, where Rome fought its first great battle with a foreign foe. The Romans were the stronger, but the Greeks had the advantage in arms and discipline. The conflict that followed was very different from the one fought by Alexander at Issus. So courageous and unyielding were the contestants that each army seven times drove back its foes.
"Beware," said an officer to Pyrrhus, as he charged at the head of his cavalry, "of that barbarian on the black horse with white feet. He has marked you for his prey."
"What is fated no man can avoid," said the king, heroically. "But neither this man nor the stoutest soldier in Italy shall encounter me for nothing."
At that instant the Italian rode at him with levelled lance and killed his horse. But his own was killed at the same instant, and while Pyrrhus was remounting his daring foe was surrounded and slain.
On this field, for the first time, the Greek spear encountered the Roman sword. The Macedonian phalanx with its long pikes was met by the Roman legion with its heavy blades. The pike of the phalanx had hitherto conquered the world. The sword of the legion was hereafter to take its place. But now neither seemed able to overcome the other. In vain the Romans sought to hew a way with their swords through the forest of pikes, and as a last resort the Roman general brought up a chosen body of cavalry, which he had held in reserve. These came on in fierce charge, but Pyrrhus met them with a more formidable reserve,—his elephants.
On beholding these strange monsters, terrible alike to horse and rider, the Roman cavalry fell back in confusion. The horses could not be brought to face their huge opponents. Their disorder broke the ranks of the infantry. Pyrrhus charged them with his Thessalian cavalry, and the Roman army was soon in total rout, leaving its camp to the mercy of its foes.
During the battle Pyrrhus, knowing that the safety of his army depended on his own life, exchanged his arms, helmet, and scarlet cloak for the armor of Megacles, one of his officers. The borrowed splendor proved fatal to Megacles. The Romans made him their mark. Every one struck at him. He was at last struck down and slain, and his helmet and cloak were carried to Lavinus, the Roman commander, who had them borne in triumph along his ranks. Pyrrhus, fearing that this mistake might prove fatal, at once threw off his helmet and rode bareheaded along his own line, to let his soldiers see that he was still alive, and that a scarlet cloak was not a king.
The battle over, Pyrrhus surveyed the field, strewn thickly with the dead of both armies, his valiant soul moved to a new respect for his foes.
