doubled into maniples and the most experienced officers set in a chain of command. Old signal horns had been procured and three simple sequences repeated until the least of them could be expected to halt, withdraw or attack. Anything more complex would give them difficulty, Seneca acknowledged, but he looked satisfied as he marched. They were well-armed, well-fed and from the greatest fighting nation the world had ever known. Every legion began with nothing more than the culture and a few good officers. For road guards who had felt forgotten by the city they served, this was their chance. It helped that they stood against traitors with the city behind them. Most had family in Rome and would fight far better for them than for some lofty ideal of the Senate.
Ahenobarbus felt the eyes of the men around him and his spirits soared at the responsibility he had prayed for all his life. Just marching with them was a joy that was difficult to mask. He could not have asked for more from the gods and swore he would make an offering of a sixth of his wealth if they gave Caesar into his hands.
The scouts had marked the enemy forces ten miles north of Corfinium and that was a distance they could cover in less than three hours. Ahenobarbus had been tempted to ride, but sense had overruled his vanity. The men would see he walked with them, and when the time came he would draw his sword and hurl his spears with the rest.
Seneca had drawn up a plan of attack and, despite himself, Ahenobarbus had been impressed at his knowledge. It was one thing to give the order, quite another to create the formations and the tactics. It helped that they were facing Roman-trained soldiers, Seneca said. Only the lie of the land was unknown. Everything else would be by the military manuals and Seneca had read all of them.
Even Ahenobarbus’ initial impression of the recruits had altered as the ranks took shape. It took hard men to run isolated road posts and more than a few had fought in Greece and Spain before ending their careers on the forts. They marched in a perfect column and Ahenobarbus was only sorry they did not have drummers to sound the beat for them.
It was difficult not to imagine the honours Pompey would bestow for capturing a man who threatened the city. At the very least, it would mean a tribune’s rank, or a position as a magistrate. At his age, Ahenobarbus knew he would not be allowed another command, but it did not matter. He would have this day as a memory no matter what came after. In truth, leading a legion in some lonely mountains far from home did not appeal. It was far better to picture the soft life of attending court and accepting bribes from the sons of senators.
The countryside was filled with small farms, with every piece of flat ground taken up with waving wheat and barley to feed the maw of the city to the south. Only the road remained clear and Ahenobarbus did not look at those merchants who had dragged their carts off the stones to let his legion pass. His legion.
As soon as his scouts reported that Ahenobarbus had left Corfinium, Julius gave the order to march. If the commander of the guards declined the chance to attack, Julius trusted his veterans to catch them on the road before they could reach the safety of Rome. He had no fear of the untested troops. His Tenth had faced overwhelming numbers, ambush, night attacks, even the chariots of the Britons. He would trust them against any force in the world, if it were a matter of killing. Taking the guards alive would be a harder challenge and the extraordinarii riders had been racing back and forth between Brutus and the Tenth all morning with orders. The idea of forcing a surrender was a new one in Julius’ experience, especially against Roman legionaries. Without an absolutely overwhelming advantage, he knew his people would fight to the last man rather than leave Rome open. From the first contact, he had to terrify them into obedience.
The veteran Tenth breasted through the wheat, trampling it in a great swathe. Even in a wide formation, Julius could see the lines in the fields behind them stretching for miles, as if metal tines had been drawn across the earth. It was a straight path, despite the rise and fall of the landscape. The extraordinarii rode ahead, searching for the first sight of the Roman enemy. The Tenth loosened their swords in their scabbards as they marched, waiting for the horns that would send them into a battle line.
Ahenobarbus saw the dark stain of the enemy across the land and his heart began to race in anticipation. Seneca had the horns sound a warning note and the blare stiffened the backs of his soldiers, tightening their nerves. Almost unconsciously, the pace of the march increased.
‘Form square!’ Seneca roared along the ranks and the column dissolved as the centuries moved apart.
It was not a parade manoeuvre, but the formation appeared out of the lines like the head of a hammer, with the handle trailing behind along the wide road. Gradually, the tail dwindled in length until they were going forward in one solid mass. Their spears were gripped in sweating palms as they readied themselves for battle and Ahenobarbus could hear the muttered prayers of the men around him as they gave up their souls and pressed on. He thanked his gods to have been given such a moment as they crossed into the wheat and trampled it before them. He could not turn his head away from the shining metal of the Gaul legion. These men threatened his city and he watched them approach in fascination and swelling fear. He heard their own horns whine across the fields and saw the swift response as the lines blurred into smaller units, sliding inexorably towards him.
‘Be ready,’ he called across the heads of his countrymen, blinking sweat from his eyes. Then the stillness of the day snapped as the Tenth legion roared and broke into a run.
Julius advanced with the others, keeping a tight rein so as not to go beyond his loping men. He watched the distance shrink as both sides accelerated and tasted the dust of the fields in his mouth. The Tenth had not unwrapped their spears and he hoped they understood the plans he had made. They raced across the open ground towards the road guards in their formations and after their first shout they were grim and terrifyingly silent.
Julius counted the paces between the two armies, gauging the range. He doubted Ahenobarbus could launch spears in full waves from such a motley gang, but he would have to risk the lives of his Tenth to get close enough.
At the last moment, he called the halt and the Tenth crashed to a stop. Julius ignored the enemy as they lumbered towards him. There were fifty paces to go before they were in range for spears, but he searched beyond them in the distance, looking for the rising dust that would show him his veteran legions marching around. With the tramp of the road guards in his ears, Julius rose up in the saddle, balancing on one knee.
‘There they are!’ he called, exulting.
Hidden by the hills, Brutus, Domitius and Mark Antony had circled and Ahenobarbus was caught between two forces. Julius knew he could have destroyed them, but his aim was more subtle and more difficult. As Ahenobarbus came into spear range, Julius raised his hand and wound it in a circle above his head. The Tenth wheeled right and marched, keeping their distance all the time. It was as if they were attached by a long rope to the enemy, and the move forced the road guards to turn with them or leave their flanks open.
Julius grinned to himself as he saw the chaos that ensued. It took more than a few simple horn signals to turn a square on the spot. He saw the lines compress and widen as those in front tried to match the Tenth and those behind became confused and angry.
The Tenth moved around the rim of the wheel and when they had made a full quarter turn, Brutus had the Third bellow out a challenge and approach. Julius nodded in fierce excitement as he saw the veterans move apart into an arc as if they were on parade. They closed off the retreat and added to the confusion and terror in those they surrounded.
The men with Ahenobarbus were caught. Some of them tried to face the new threats, but all four legions turned about them, causing chaos in the milling centre. No spears could be launched from within that confused mass.
The revolving armies raised a plume of dust from the wheatfields, thickening the air and making men cough and sneeze. Ahenobarbus
