'For fuck's sake! Stay down!'

'No! No. We must run. Run for it!'

Proculus started to rise up from the grass, kicking out at the arm that grasped his tunic. 'Let go!'

Figulus glanced at the approaching horsemen, and instinctively rose up behind Proculus. He threw himself forward, smothering the man as the two of them crashed back to the ground. The optio slammed the pommel of his sword into the side of the legionary's head and Proculus went limp at once. Figulus took no chances and lay across the inert body, sword poised at the man's throat as the horsemen rumbled towards them.

Almost at the last moment the column edged fractionally away from the men in the grass and began to pass down the side of the prone figures, no more than twenty feet away. Cato's head was turned to the side and he hardly breathed as he stared at the dark shapes of men huddled inside their cloaks as they urged their mounts back towards the promise of a dry tent and shelter from the rain and wind. The column pounded along, quite oblivious to the legionaries, yet it seemed to Cato that the last of the horsemen would never pass them. Just when he felt an almost overwhelming urge to rise up and throw himself upon the mounted scouts, the tail of the column galloped by. Cato watched the back of the last horseman, watched him ride on towards the camp, and he drew a deep breath and released some of the tension that had wound his muscles up as tight as a quartermaster's purse. He waited until the end of the scout column was far enough away that he could not make out any details before he passed the word for his men to continue towards the copse.

It took the best part of an hour before Figulus joined the others crouching in the dark shadows beneath the dripping boughs of the oak trees. Proculus was conscious again, but groggy, and he made no protest as the optio thrust him towards the others. Cato looked back towards the fortress, but there was no sign that the alarm had been raised yet. By his reckoning they had no more than four hours under the cover of night: enough to put perhaps as much as ten miles between themselves and the first of the pursuers. The fringe of the marsh, as far as he could recall, was at least fifteen miles away. It would be a close thing.

And then what?

The perils and uncertainties of the future weighed down on Cato's heart like a sack of rocks. If they were caught by their own side, execution would follow swiftly, and a stoning, or being beaten to death would be the least of the agonies an angry General Plautius would visit on them. A slow, agonising death by crucifixion was more than likely. And if the enemy got to them first the Romans would be sure to suffer some barbaric torment: burning alive, flaying or being thrown to the dogs. And if they managed to evade both sides, then they would hide in the marshes, reduced to eating anything they could find or steal. A lingering starvation then, until winter killed them off.

For a moment Cato was tempted to turn round and accept the least terrible of these fates. But then he cursed himself for being a weak-minded fool. He was alive, and that was all that mattered. And he would cling on to life for all he was worth; for even the worst of lives was better than the endless oblivion of death. Cato had little faith in the afterlife vouchsafed by Mithras, the mysterious god from the east who had found so much secret favour with the men of the legions. Death was final and absolute, and the only thing that mattered was to defy its cold embrace until the very last breath whispered from his lungs.

Cato shrugged off his morbid reflections and stood up, his wet body trembling as the keen breeze bit into his flesh.

'On your feet!' he called out, and without waiting for the others to obey his order, the centurion turned away from the camp and struck out towards the gloomy haven of the marshes to the west.

05 The Eagles Prey

CHAPTER TWENTY-TWO

Macro was wide awake when the alarm was sounded. He had not been able to sleep since he returned to his tent. That was something of a first for Macro, who, like most veterans, usually dropped into a deep sleep the moment his head hit the bolster. But the situation was far from usual. Cato was out there, with the most slender chance of survival, and Macro himself was in considerable danger. The moment the quartermaster's assistants were discovered bound and gagged in the equipment tent it would be clear that someone had aided the prisoners' escape. If they discovered his involvement then he would be standing in for those who had been facing execution. There was little doubt in his mind about that. Rank and exemplary battle record notwithstanding, Macro would be killed.

Now the first faint tinge of light washed the sky a dull grey through the gap in his tent flaps. It was still raining, not as heavily as during the night, but still a steady tapping on the leather over his head and a wet rustling sound from outside. A shout sounded in the distance, calling the duty century to arms. A squad of men ran past his tent, dark silhouettes against the strengthening light, feet slithering and squelching in the mud.

Macro decided that he had better get outside and be seen to be responding to the alarm. His survival depended on him acting as if he was as surprised as the rest. He swung his feet over the side of the camp bed and reached for his boots. As his fingers closed on the well-seasoned leather he paused, let go of them and quickly ducked out of the tent.

'You!' He pointed to one of the men running past. 'What's all the bloody racket about?'

The legionary stopped, stood to attention, breathing heavily. 'The prisoners, sir.'

'What about 'em?'

'They've gone, sir. Escaped.'

'Bollocks! How could they?'

The legionary shrugged helplessly. He had no idea, and couldn't be expected to know the details.

Macro nodded. 'Very well then. Carry on.'

'Sir!' The legionary saluted, then turned back towards his standard, slowly being waved from side to side in the distance, above the ridges of the line of tents. Macro watched him go, noting the difficulty the man had in making any speedy process over the glutinous mud that surrounded the tents. That was good. Anything that might slow down the pursuit of Cato and his men. Ducking back inside his tent Macro hurriedly laced on his boots and swept up his heavy cape. The folds of wool had only recently been greased and would keep most of the water out. Cato's men had no such comfort and would be shivering in sodden tunics he realised, with a momentary pang of conscience. But there had been no time to grab anything more than the weapons, and that had been a big enough risk for him and Figulus to take. Cato would have to make do and be thankful that he was alive at least, Macro reflected as he strode off to join the men gathering around the standard.

Centurion Maximius came trotting up to join his officers, his cloak bundled under his arm.

'What's the alarm?'

Tullius, commanding the duty century, stiffened his back and stepped forward. 'Prisoners have escaped, sir.'

'Escaped?' Maximius was astonished. 'That's not possible. Show me.'

Tullius turned towards the open area where the prisoners had been held, and his men stumbled back to clear a path for the officers. They marched up to the holding area and approached the two sentries that Figulus had knocked out. They were sitting on the ground, drinking from the canteens of the men who had set them free.

'What the hell are you doing?' Maximius bawled out. 'On your bloody feet!'

The two men clambered up stiffly and stood to attention with the other legionaries as the officers strode up to them. The cohort commander ignored them at first, casting his gaze on the flattened grass where the prisoners had been held. He took three quick paces, bent down and snatched up some severed lengths of leather from the ground, then glanced at them closely before holding them up for the other officers to see.
