'Bolt throwers.' He smiled to himself. 'Macro's using incendiaries. Clever bastard.'

Macro kept up a steady stream of flaming bolts as the enemy vessels approached, and then there was a dark swirl of smoke from over the headland and Cato saw that the ships had changed course, forced to give the headland a wide berth to avoid the weapons shooting at them from the watchtower. One vessel was already alight. Cato gripped the rail of the turret as he continued to watch. Beneath his feet he detected the faintest of lurches as the men at the oars made one last effort. By the time the trierarch had returned to the bows, the point was in sight and Cato knew that the contest was over. Forced aside by Macro, Ajax and his ships could not reach the open sea in time to make a clear escape.

'We'll have them, sir.' The trierarch grinned.

'So it seems,' Cato replied as calmly as he could manage. 'Have the marines stand to.'

The headland dipped down to a small sandy spit at the edge of the turquoise sea and the Sobek continued a short distance beyond before the triearch ordered the steersman to turn directly into the bay. From the turret Cato had a clear view of the two vessels making towards him, less than quarter of a mile away. To the right was the ship Ajax had seized when he fled from Crete. The other was the Thoth, from which smoke billowed from a fire raging amidships. Several men were drawing buckets from the sea and attempting to dowse the flames that threatened the ship. Even so, the crew stuck to their oars and the ship ploughed on, water surging over the ram and down her sides. Cato strained his eyes to see if he could spot Ajax on either ship. There was too much smoke and too many figures dashing around the deck of the Thoth to be certain of picking out a single man and he concentrated his attention on the other ship. A handful of archers stood in the turret on the foredeck and more armed men waited on the main deck. Then, as the distance rapidly closed, Cato saw a figure push his way through to the bows, tall and broad and wearing a decorated black cuirass and a brilliantly polished helmet with a black crest of billowing feathers.

'Ajax,' Cato whispered to himself. His heart hardened pitilessly as he beheld the rebel slave who was the cause of so much death and suffering. Cato thought fitfully of Julia and the humiliation she had suffered at the gladiator's hands. His fists clenched hard as he gave his order to Phermon.

'We'll take the ship on the right. Let the other one burn.'

'Aye, sir.' The trierarch cupped a hand to his mouth and turned aft. 'Steersman! Make for the starboard vessel!'

The steersman leaned into his tiller and the ship came round and steadied on a course bow to bow with the oncoming vessel. Cato stared at Ajax, and then slipped his hand down to the pommel of his sword. It was a shame that Macro was not at his side to take his share of the long-awaited revenge, thought Cato. He had little doubt that Ajax and his lieutenants would far sooner go down fighting than be captured and suffer a lingering and humiliating death by crucifixion.

'Excuse me, sir,' a voice called and Cato looked round as a marine climbed into the turret, clutching a bow and a quiver filled with arrows. Two more men joined him and Cato moved to one side to give them room. On the enemy ship he could see Ajax's bowman fitting arrows to their strings before they aimed their bows high as the two ships ploughed towards each other across the tranquil surface of the bay. They loosed off the first volley of arrows and Cato watched impassively as the tiny specks swept up, high into the air, then seemed to pause briefly before plummeting down towards the Sobek. Most struck the water, twenty or so paces in front of the bow, disappearing with a faint plop and glittering spout of water. One struck the strake at the front of the ship with a loud crack and the flights trembled for a moment before they were still. The next shots would be in range, Cato knew.

'Shall we shoot back, sir?' asked one of the marines.

'No. Save it for when you can't miss.' Cato leaned forward and called down to the legionaries crowded together beside the turret. 'Men! Shields up!'

He glanced back over his shoulder. The next Roman ship was rounding the headland and the rest were close behind as they struggled to keep up with Cato's vessel. The crew of the burning enemy vessel saw that escape was impossible and they turned away from the approaching warships, back across the bay in what seemed a futile bid to escape their pursuers.

A series of cracks snapped Cato's attention back to Ajax's ship. The second volley of arrows had struck home, sticking into the foredeck, the bows of the ship and two of the shields held up by the legionaries. Mercifully no one had been killed or injured. The oncoming ship was now no more than a hundred paces away and Cato could see Ajax and his men clearly as they readied their weapons.

'We'll take them on the starboard side!' the trierarch called to the steersman, who made a small adjustment so that the Sobek edged fractionally away from the other ship's ram. 'Stand by for collison!'

Cato grasped the rail of the turret and braced his feet on the deck. All around him the other members of the crew hurriedly prepared for the impact. There was a last flurry of arrows from the enemy ship and a cry of pain as a barbed point tore through the neck of one of the archers standing in the turret. Cato spared the man a quick glance and saw him crumple on to the floor of the turret, blood gushing from a severed artery. There was nothing that could be done for him and Cato looked forward again.

'Ship oars!' Phermon bellowed and there was a frantic clatter and rumble as the crew fed them back into the hull.

The flared tip of the ram caught the enemy ship on the bow and there was a jarring crash as men stumbled forward. Both rams had struck glancing blows and now the ships began to pass alongside each other. The enemy commander had failed to give the order to ship oars and with a series of sharp shattering sounds the oars on the starboard side were smashed to splinters as the Sobek's bow ground along the length of the enemy ship.

'Lower the corvus!' Cato shouted down to the decurion of marines. 'Quickly, man!'

The marines hurriedly recovered their balance and began to swing the boarding device out and over the enemy deck. The archers in the bow were directed towards the danger by their commander and they hurriedly loosed off their arrows at the marines. Unable to defend themselves while they manoeuvred the corvus into position, they were vulnerable to enemy missiles and two were struck down in quick succession as the arrows whirred across the deck. A moment later Cato saw another man cry out as his arm was pierced through.

'Release!' the decurion yelled as soon as the iron point was over the enemy's deck. His men let go of the rope and it shot up towards the pulley as the gangway arced down. The renegades dived aside to avoid being crushed, or impaled, and with a deep thud the spike pierced the deck. There was a jolt and a groan as the stout wooden peg at the base of the corvus took the strain from the remaining momentum of both ships.

'Boarding party away!' the decurion called out as he drew his sword and scurried across the gangway towards the enemy deck. His men rushed after him, shields raised and swords drawn and ready. The enemy archers loosed more arrows, most of which struck the wooden hoardings that protected the men as they crossed from the Sobek. A few arrows overshot, and missed the ship and crew entirely.

Cato turned to the archers in the turret and pointed out their opposite numbers. 'Shoot those men down!'

The marines hastily notched their arrows, drew back the strings as they aimed, paused and then released their fingers, sending their arrows whipping through the air towards Ajax's men. Cato nodded with savage satisfaction as he saw two arrows strike one of the enemy archers and send him sprawling on to his back.
