Then a new roar of acclamation broke upward and rolled away to the east. Two richly armed riders parted from the group and dashed off: Maharbal, light and slender, bending far over his horse's neck, rode headlong in Numidian fashion to his Numidians; Hasdrubal, erect and dignified, galloped to head the Gaulish and Spanish horse upon the banks of Aufidus; trumpets, drums, cymbals, crashed out in mad, barbaric discords; and, with their horse-head standards tossing amid the forest of spears, the Carthaginian line drove forward to the attack.
Running fast before the line of battle, Sergius could still make out, even through the dust, those same naked men with lynx-hide bucklers, dotting the plain at regular intervals, and each man's right arm seemed always whirling about his head. The Roman light troops had pushed on to skirmish, and now they began to fall back, though no arrow or javelin could have reached them—could have flown to the foe. Sergius watched in surprise their confusion and terror as they sought to plunge among the legionaries or hide themselves behind the horsemen; nor had they fled unscathed. Here a man ran by screaming and clasping his shattered hand to his breast; then another staggered up, with arm hanging broken at his side, while the big drops of blood fell slowly from his fingers; and yet a third appeared, pale and helpless, supported between two companions.
Sounds, too, now dull and heavy, and again ringing and metallic, seemed to punctuate the roar of the advancing host. Sergius saw a horseman near him clap his hand to his forehead and plunge headlong to the earth: horses reared and snorted, some fell with ugly, red blotches on their breasts and throats; the clangour and the thuds came faster—faster; for now the clay and leaden bullets of the slingers fell in showers, like hailstones, and it was good armour that turned them.
Manlius had leaped down to aid a friend who was reeling helplessly, with both eyes beaten out, and, a moment later, he approached Sergius, holding up a slinger's bullet. The red had sunken into the lines of the stamped inscription, and displayed them in hideous relief, "This to your back, sheep!"
"That is always the way with barbarians," sneered Marcus Decius. "No blow without an insult—look! They shall have blows themselves, soon, that will need no insults to piece them out."
Paullus had watched with eagerness, with anxiety, for the signal to advance. Varro seemed to hesitate, while the great masses of Rome, lashed by the bitter rain of the slings, writhed and groaned in anguish and rage; the light troops had disappeared, and the Balearians, now close at hand, leaped and slung without let or hindrance. Then it was that Paullus, waiting no longer, made a sign to his trumpeters. "Scatter me that rabble!" he cried, and the cavalry clarions raised their voices in one long, swelling peal of sound.
"Close! close!" rose the shout of battle, and the Roman horse dashed forward into the dust cloud—forward upon the slingers that suddenly were not there, had vanished, as it were, into the earth itself.
The straight trumpets and curved horns of the legions were ringing behind them, stirred to life at last, but the horsemen did not hear. What were those looming up ahead? Not naked slingers—armoured cavalry! Hasdrubal with his Gauls and Spaniards were before them—upon them; and all sense and volition were lost in the terrific shock.
Line after line went down, as if at touch, while fresh lines poured on over the heaving mass of men and horses, until those who were face to face seemed to fight upon a hill. Fiercer grew the pressure, tighter and more dense the throng; horses, crushed together, powerless to move, snorted and tossed their heads in terror, while the riders leaned forward and grappled with those opposite. Weapons first, then hands clutching at throats were doing the deadly work, and the dead, man and horse, stood fast amid the press, unable even to fall and become merged into the hideous, purple thing beneath their feet.
Mere weight, though, was beginning to tell. The human ridge that had marked the joining of battle seemed far back among the enemy, and squadron after squadron, in close array, breasted its top and plunged down to mingle with the living or take their places among the dead. The Romans were giving ground, slowly, stubbornly, but unmistakably, and still, above the shouts and shrieks, the trampling and the clash of weapons, the groans and the hard, short breathing, they could hear the harsh voice of the consul, Paullus, urging his men to make battle firmly.
