The third and fourth ranks had closed up so that the legionaries stood almost shield to shield as they mopped up spearmen still living in the wake of the front ranks. There had been an attempt to open out again as the advance continued unimpeded, but there were still clots and gaps like the pattern made by frog eggs on a still pond.
The portion of Vibulenus' brain which was in control functioned like a racer's, not like that of a man in the midst of battle. It sent the young tribune through one of the gaps. Ahead of him he could see the standards and the leading elements of the legion already coming to grips with the hostile infantry.
There was a shower of stubby javelins from the enemy lines. One of the missiles, weighted near the head with a lump of stone, hit Vibulenus in the middle of the chest. The bone point shattered against the molded bronze of his breastplate, but the shock threw him back a step and brought him to his senses. Then he took the remaining two paces forward to join Clodius Afer as the file-closer hacked through the ribs of an enemy.
The tribune has lost both his helmet and his shield, but the hostile infantry were just as naked as they looked from a distance. They were taller than the Romans, but they were by no means the size of the spearmen who had ridden to battle on the war cars. Some wore peaked leather caps and bandoliers which held half a dozen javelins like that which Vibulenus' breastplate had stopped; but none of those whom the tribune saw carried shields or wore any armor that would slow an edge of Spanish steel.
One of the enemy swung his stone-weighted javelin at Clodius like a mace. It glanced off the file-closer's neck guard, making the man stagger and his helmet ring. Vibulenus stabbed upward through the enemy's belly and watched its feathers flutter as the creature toppled backward and died.
Gaius Vibulenus Caper had just killed someone-not a man, he supposed; but it might have been. And all that mattered to him at the moment was that his sword caught in something and he had to jerk very hard on the hilt to clear the weapon.
"Bastard," snarled Clodius, slashing at the dead foe who had struck him. His voice was hoarse, and he gasped out the epithet between huge breaths through his mouth and nose together. "Bastard!" and he waded forward over bodies still quivering and oozing fluids from their wounds.
"Rome," wheezed the tribune in what was meant to be a shout. He hacked down the enemy who had just stabbed his left arm.
Hostile infantry higher on the slope volleyed bone and flint-tipped javelins, but those in contact with the Roman lines attempted to use theirs as hand weapons. The points could deliver a nasty or even fatal gash, and their stone weights might have been heavy enough to crush an unprotected skull. Against Romans with shields and full armor, they were singularly ineffective.
For a minute or two, Vibulenus and the leading elements of the legion cut at opponents as thickly packed as wheat in a field-and as defenseless. Then the rearmost ranks of legionaries launched the javelins most of them still carried, arching them well beyond the line of hand to hand combat. The enemy reacted like a glass tumbler struck by a paving stone,
Roman javelins had been reasonably effective against the warriors in the first stage of the battle, creating confusion even when blocked by shields or body armor. In the naked infantry, anyone hit was a victim, and the enemy was packed so densely that most of the missiles punched through two or even three of them. More of the hostile infantry had probably died on Roman swords already, but the suddenness of this disaster in the heart of the mass blew the troops who saw it into panicked flight.
When the pressure of their fellows behind them ceased, the front line of the enemy gave up even the pretence of resisting the legion. Vibulenus fell to his knees when his sword slashed only air. The victim he had tried to decapitate fled backward before the stroke in a great rubbery bound, his feather plumes fluttering like miniature wings as he flung away his bandolier of missiles.
None of the enemy within fifty feet of the tribune were still standing when he got his own feet under him again. The ground writhed with bodies trying to stuff bright-colored intestines back into sword-cuts or withdraw javelin heads which extended as far behind as the shaft did in front of the wound. Survivors of the hostile infantry were loping away in all directions, faster than even the handful of Roman cavalry on the wings could pursue after the slogging effort of battle.
Within and ahead of the fleeing infantry were the war cars, empty now save for the drivers who were as furiously bent on escape as any of their fellows in the infantry. The vehicles (those which the legion had not overrun at first contact) had been drawn up behind the infantry, awaiting the signal to retrieve the warriors whom they had carried to battle. Now, like birds from a blazing forest, they bolted away with nothing behind them save raging disaster.
The thunder from the enemy camp ceased. Legionaries from the right flank were climbing over the low earthen wall, unresisted by those within.
Vibulenus tried to stagger forward in pursuit of the enemy. Someone grabbed him by the left shoulder. When the tribune attempted to brush off the contact in single-minded concentration on his task, he found that he had a nasty wound in the left biceps which he could not remember receiving.
All the strength and determination drained out of the young tribune. He slipped into a sitting posture on the ground. The lower edge of his breastplate gouged him as he slumped, but at the moment he did not have the intellect to care or the energy to do anything about the discomfort.
"That's right, boy," said Clodius Afer, releasing Vibulenus' shoulder and sprawling down onto the ground himself now that he had stopped the younger man. "We've done our job-leave the rest to those as are fresh."
The filer closer took off his helmet and gestured with it at the rear ranks of the legion streaming on in distant pursuit of the enemy. The legionaries would not catch many of their naked foes, but their pressure would keep the enemy from regrouping and launching an attack on men exhausted by victory. "You get so tired," Clodius went on musingly, "you run right up on a spear and you don't know you've done it. Got to know when to stop, boy." He began to massage the back of his neck. Vibulenus could see the skin there had been scraped when the hostile mace drove down the helmet edge.
The tribune looked at Clodius. The younger man's vision had, since he sat down, been an apathetic blur for want of brain capacity to process what he was seeing.
Now the non-com's face sprang into sharp focus. The skin was flushed, and ghostly red and white outlines remained from the pressure of the helmet rim and cheek pieces during the battle.
Clodius' eyes were open. They held no expression, but the crow's feet at their corners belied the youthfulness suggested by the man's thick black hair.
The file-closer was breathing through his mouth, though the breaths were controlled and not the gasping spasms which thrust Vibulenus' ribs against the inside of his body armor. The non-com had the look of an ox in the traces, tired but stolid and immensely powerful.
The tribune remembered the way Clodius had struck Rufus as the legion deployed. He realized now that the veteran had known too well what the next hours would be like, and his knowledge had made him savagely intolerant of lapses in discipline.
Vibulenus glanced at his sword. Fresh, the blood on it had looked normal enough; but as the fluid dried, it took on a purplish sheen. His face stilled to hide his awareness that his right arm to the elbow was covered with the same inhuman fluid, Vibulenus began to wipe the flats of his weapon on the grass and gritty soil. His left arm was too stiff to use, and when he tried to move it, the scab and exposed muscle crackled painfully.
