One of Vacula's men interposed his shield between a spear and the centurion momentarily, but another warrior took the legionary out of the fight with a thrust through the mail shirt and belly. The non-com was still off balance from his throw and more intent on drawing his sword than on swinging his shield into a posture of defense. One long spear tore through the apron of bronze-studded leather meant to protect the centurion's thighs. While Vacula thrashed like an eel on a fisherman's trident, another warrior thrust through the bridge of his nose.

The surviving legionary slipped aside, his javelin poised as a threat to keep the warriors away from him now that they had finished with his fellows.

Clodius Afer's leg came free. Almost as part of the same motion, he vaulted down from the vehicle to stand between Vibulenus and the warriors advancing with bloody spears. "Watch it, sir!" called the file-closer. "Watch it!"

The tribune picked up his shield by the center strap, acting in too much haste to thread his forearm properly through the loop and then grip the real handhold at the rim.

One of the warriors stabbed at Clodius, but the veteran responded by shifting a handsbreadth to block the point with the thick, keel-like boss of his shield.

Vibulenus' sword stood pommel-up and ready to his hand, caught by the same matting which had held Clodius' foot. He drew it as he jumped down and almost lost the weapon again. The rope fibers snagged the notch left in the blade when it met the spearhead. A warrior thrust at him, and only Clodius' quick sideways chop with his sword stopped the spear from taking Vibulenus through the chest.

"Watch it, puppy!" the non-com screamed, barely able to block a thrust from his own left side.

The Pompilius cousins, Rufus and Niger, launched their heavy javelins as they scrambled over the wrack of vehicles and dead or dying animals. Neither missile was artfully aimed, but one wobbled into the throat of a warrior concentrating on another attempt at Clodius.

The wounded spearman bleated and staggered into one of his fellows. The third warrior, disconcerted, backed a step to take stock of the situation. Gaius Vibulenus, to whom everything since the attack had begun was a white blur, saw an opportunity with the clarity of the moon in a starry sky. He ducked low and swung the bronze-bound edge of his shield onto the bare instep of the warrior who was backing away. The way the small bones crunched made hair raise on the tribune's own neck.

"Come on, boys!" the file-closer shouted with his feet planted and his shield raised. The Pompilii and three of their comrades swept down from one side, and the survivor of the legionaries who had accompanied Vacula circled the hostile spearmen from the other.

The warrior whom Vibulenus had disabled bludgeoned the tribune with his spear shaft. Vibulenus' helmet had been knocked off at the start of the action, but he had not noticed it was missing. The spear was too awkward to be a good club, but the warrior made up with strength and the shaft's weight for any lack of quickness.

Vibulenus sprawled on his back with his eyes and mouth wide open. The sky was a pale orange, a complement to the color it had been a moment before, and against it the young Roman had a double vision of the spearhead which the warrior had poised to finish the job he had started with the shaft. The weapon disappeared in a blur of armored skirts and the blocky, powerful thighs of Clodius Afer, lunging between Vibulenus and death.

The tribune thought he was getting to his feet again only seconds later, but all the warriors he had been facing were dead on the ground and no Roman he recognized was anywhere around. The sixth rank of legionaries had already marched by, disordered somewhat by the debris on the field but not by fighting. Each of the men held one javelin in the right hand and the other, heavier, missile gripped against the shield back.

Beyond them, already starting up the slope toward the enemy camp, were the leaders of the Roman advance. Among them Vibulenus could see the standard of the Third Century and the stocky form of Clodius Afer who was looking back over his shoulder to shout encouragement.

The tribune's vision was clear again. If it had not been…

All of Vibulenus' muscles seemed to work, but when he moved he had the feeling that his body had become a water-filled bladder and that there were no bones within his skin. The only war cars he could see were disabled ones and the few racing, empty but for their drivers, toward the shelter of the massed infantry.

Annihilation of the armored spearmen had scarcely changed the balance of numbers. Tens of thousands of the enemy remained; and Vacula, with pink brains leaking out of the hole which included both eyesockets, was only one reminder that the legion had suffered casualties as well.

The tribune picked up the sword he had dropped. The effort of bending and rising made the left side of his head throb as if he had just been clubbed there again. He retched, but there was nothing left for his stomach to heave up. When he wiped his mouth with the back of his hand, he remembered that he had vomited when he first tried to get to his feet. He had forgotten that…

Horns and trumpets called from Vibulenus' right, and the young tribune turned toward the source of the sound. Well behind the last rank, the command group was picking its way through the wreckage-once living and otherwise-of battle.

There were two men on horseback, Falco and another of the tribunes. The rest of the command group was mounted on beasts which bore far less resemblance to horses than the four-horned draft animals of the enemy did to oxen. They were carnivorous, beyond doubt: giant lions, perhaps, or even huger dogs. They wore coats of iron scales, like the horses of the richest Parthian cataphracts. The score of inhuman riders mounted on them, the Commander's bodyguard, were armored in jointed suits which must have weighed hundreds of pounds apiece.

Gaius Vibulenus had not known where his place was. He still was not sure, but he knew he did not belong here, behind the legion, with Falco and those who had bought the Roman prisoners from their Parthian captors.

The young tribune began to jog down the remainder of the slope, clutching his sword but leaving his shield behind with the bodies. Every time his foot hit the ground, it pumped his skull airily lighter so that the pain resonating inside it became diluted to heat and a mild pressure.

When he opened his mouth to cry, "Rome!" he found that his constricted throat would not pass even a croak. He tried to shout anyway as he staggered like a drunk or a madman, reaching the sixth rank as its legionaries dodged the more numerous trees at the low point of the valley.

There were sounds of further fighting ahead, but the upward slope blocked vision. The slight decline from the opposite side of the valley had given the rear ranks an almost theatrical view of the start of the battle.

Gaius Vibulenus was an inch or two taller than most of the line soldiers, because his family could afford to feed him well as a child. That was not enough of a height advantage to permit him to see over the helmets and crests, short black brushes for the legionaries and red transverse combs to mark the centurions. He struggled through the ranks, bumping and once pushing aside the troops who were doing their best to keep their order: the only task they were called on to perform at this moment.

Ahead were the shouts of men and the clattering of weapons, brilliants of sound embroidered on the thunderous background still shuddering from the enemy camp. The young tribune thought of hogs stumbling through chutes toward the slaughterer's knife, fearful and unable to see anything but the gap toward which they plunged between high board walls.
