Cato was terrified, and for an instant the urge to turn and run seized his limbs. Then the horror of showing his fear in front of his men rescued him and he welcomed the cold chill of fright that pulsed through him and keyed up every muscle, and every one of his senses, in readiness for the imminent need to kill and to live. He made himself stand still a few heartbeats longer and face the howling mob racing across the grass towards the Roman line. Then he turned and walked towards the front rank of his century.
'Standard to the rear!' Cato thought he heard a tremor in his voice and concentrated on steadying it for the next order. 'Keep your shields up!'
As he assumed his position in the middle of the front rank Cato took a firm grasp on the handle of the shield Figulus held ready for him, and drew his sword.
At the far end of the cohort, Maximius cupped a hand to his mouth and roared out an order, only just audible above the din of the charging tribesmen. 'Front rank… ready javelins!'
The front rank rippled forward as the men advanced two paces and halted.
'Prepare!'
The men twisted at the waist and reached back with their right arms, angling the shafts of their javelins up towards the sky. Then they tensed, waiting for the final order. Maximius faced the enemy, gauging the gap between the Britons and his cohort. He let them come on, sprinting across the rich green tufts of grass. When they were no more than thirty paces away he swung back to his men.
'Release!'
There was a deep grunt from the front rank as their arms shot the javelins forward and a slender veil of dark shafts curved up, slowing as they reached the peak of their trajectory, then dipped, picking up speed, and clattered and thudded into the ranks of the enemy. The range was short, and scores of the Britons were struck down – pierced through by the heavy iron heads of the Roman javelins.
'Rear ranks, down javelins and move forward!' Maximius yelled, and the rest of the cohort stepped into position behind the men of the front rank, who quickly drew their swords and braced themselves for the impact of the charge. An instant later the Britons hurled themselves upon the Roman line, hacking and thrusting at the wide curved shields with their long swords and spears. Some, more powerfully built than their comrades, burst through the gaps between the shields, and straight on to the points of the swords of the men in the rank behind. Cato, tall and thin, was thrust back by a body piling into the surface of his shield. He gave ground, but as the enemy warrior plunged into the Sixth Century, he was cut down by the frenzied thrusts of the man to the left of Cato. The centurion briefly nodded his thanks to Velius and thrust his way back into line.
Once the immediate impact of the charge had been absorbed the Roman line quickly re-formed and the Britons were whittled down as they vented their rage and frustration on the red shields. Cato blocked the blows of the enemies in front of him, and thrust his blade out between his shield and that of the man next to him whenever a Briton dared to come within range. When he could, Cato glanced to each side to try to snatch some overview of how the fight was progressing. Despite the initial ferocity of their charge, the Britons were outnumbered and outfought, and the Roman line was never in danger of being broken.
Above the clash and thud and cries of battle Cato heard a command being passed along the cohort, and saw, away to his right, the First Century edge forward. Then he heard Centurion Felix's voice, nearby, bellow an order.
'Advance!'
As the Fifth began to press forward Cato repeated the order to his men and the legionaries leaned into the curve of their shields and pressed into the loose ranks of the enemy. With the Roman line thrusting forwards, the tribesmen had even less space to wield their longer blades and the exultant battle cries of a moment earlier died in their throats as each man sought to get away from the vicious blades of the short swords that stabbed out from between the broad shields. As it was only a skirmish there was no mass of bodies behind them to pin them in place and the Britons began to back away. Cato, watching over the metal rim of his shield, saw the men in front of him give ground, then there was a clear gap between the two sides. The legionaries continued to tramp forwards in close formation, then they passed over the line of those struck down by the javelin volley. They killed the injured as they tramped by and moved steadily on. There was no pretence of further resistance now, and the Britons broke and fled.
Ahead lay the river, and as soon as they realised the danger of being caught in between the iron and the water the Britons started to run towards the flanks of the cohort, hoping to escape round them while they still could. But the decurion and his men lay in wait with a half-squadron at each end of the Roman line. They spurred their horses on and cut down the fleeing warriors without mercy. Denied any escape on the flanks the Britons turned once more towards the river and, with the current gliding peacefully at their backs they made ready to die. Cato estimated that there were more than a hundred of them left, and many had lost or abandoned their weapons and stood with clenched fists and bared teeth, wild-eyed with terror. They were finished, he realised. All that was left to them now was death or surrender. Cato drew a deep breath and called out in Celtic.
'Drop your weapons! Drop them, or die!'
The warriors' eyes turned towards him, some filled with defiance, some with hope. Still the legionaries closed in on them, and the warriors retreated, splashing into the shallows of the Tamesis, then wading out until water reached their waists.
'Throw your weapons down!' Cato ordered. 'Do it!'
At once one of the warriors turned and tossed his sword out into deeper waters. Another followed suit, and then the rest threw down their weapons and stood in the slow current watching the Romans anxiously.
Cato turned down the line of the cohort, cupping a hand to his mouth. 'Halt! Halt!'
The centuries slowed and then stood still, a few paces short of the river bank. Cato saw the cohort commander break away from the end of the first cohort and come trotting down the line towards him.
'What do you think you're doing?' Maximius barked as he reached Cato.
'I told them to surrender, sir.'
'Surrender?' Maximius raised his eyebrows in frank astonishment. 'Who said anything about taking prisoners?'
Cato frowned.'But, sir, I thought you wanted prisoners…'
'After what they did? What the hell were you thinking?'
'I was trying to save lives, sir. Ours as well as theirs.'
'I see.' Maximius glanced round at the Sixth Century and leaned closer to their centurion before he continued quietly. 'This is no time for noble sentiments, young Cato. We can't afford to burden ourselves with prisoners. Besides, you didn't see what they did to the men back in the fort. My friend Porcinus… They have to die.'
'Sir, they're unarmed. They've surrendered. It wouldn't be right. Not now.'
'Wouldn't be right?' Maximius laughed and shook his head. 'This isn't a game. There aren't any rules here, Cato.'
There was no mercy in the commander's eyes, and Cato desperately tried another tack.
'Sir, they might have valuable intelligence. If we send them to the rear for interrogation-'
'No. I can't afford to detach men for guard duties.' Maximius drew his lips back in a faint smile. He turned round to Cato's men. 'Get them out of there! Get 'em out and bind their hands. Use strips from their clothing.'
