Finally they rode up the side of one last bluff, and found themselves looking down like spectators in a theatre upon the awesome spectacle of a great battle.

The lines stretched for perhaps two miles, though their length was obscured by toiling clouds of powder smoke. A Fimbrian army was at bay there, fighting for its life. Corfe could see the fearsome bristle of a pike phalanx, eight men deep, and on its flanks thin formations of arquebusiers. But there were other western troops present also. Torunnan cuirassiers, perhaps three hundred of them, and several thousand sword-and-buckler men and arquebusiers intermingled, struggling against immense odds to extend their flanks. So Martellus was here. The dyke garrison must have marched more quickly than Joshelin had given it credit for. They had joined up with the Fimbrians, and for the first time in history were fighting shoulder to shoulder with their ancient foes. So few of them. Martellus had lost over half his command.

The Merduk host they were pitted against was vast. At least thirty or forty thousand men were hammering against the western lines, and Corfe could see more coming down from the south-east, fresh formations on flank marches which would encircle the western troops. The battle to their front was no more than a holding action. When the Merduks had their flanking units in place they would attack from all sides at once and nothing, not Fimbrian valour nor Torunnan stubbornness, would be able to resist them.

Look for a thin place, a weakness. Somewhere to strike which would lever open the enemy lines and sow the greatest confusion possible. Corfe thought he saw it. A long ridge ran to the left rear of the western battle-line, part of the outlying chain of hills which came trailing down from the south-western heights of the Thurian Mountains. The North More, men called them. Already, Merduk regiments were on the ridge’s lower slopes, but the crest was empty. They had moved down from the summit to get within arquebus range, and there was nothing but emptiness behind them. Why should they look to their rear? They did not fear the arrival of Torunnan reinforcements. They were so intent on annihilating Martellus and Barbius that they had left themselves vulnerable. A strong blow would break open the trap there, might even roll up the enemy right flank. That was the place. That was what he must do.

“Back to the command,” he told his two companions, and they set off at a full gallop for the column.

A hasty council of war during which Corfe outlined to Andruw, Ebro, Marsch, Joshelin and Morin his plan. Morin had become very quiet, but his eyes were shining. Clearly, he was in favour of attacking. Marsch was as imperturbable as always—Corfe might have been ordering him to go and buy a loaf of bread—and Joshelin obviously approved of anything which might help his countrymen. But Andruw and Ebro both looked troubled. It was Andruw who spoke up. “You’re sure about this, Corfe? I mean, we’ve faced long odds before, but this . . .”

“I’m sure, Haptman,” Corfe told him. Time was wasting, and men were dying. He was chafing to be off. “Gentlemen, to your commands. I will lead the column. No trumpets, no damn shouting or cheering until I have you all in position and you hear Cerne give the order to charge. You have five minutes, then we move on my order.”

The Cathedrallers were on the move less than ten minutes later. They shook out into three parallel columns, each over four hundred men strong. Corfe, Cerne and Morin made a little arrow of riders at their head. The monumental, earth-trembling roar of the battle ahead was rising to a climax. Corfe hoped he would not find the western forces completely swept away when they reached the top of the ridge. There would be nothing for it then but a headlong retreat to Torunn, the inevitable brutality of another siege. Defeat, utter and final. He found himself mouthing childish prayers he had not uttered in decades as his horse ascended the north-west slope of the ridge which hid the battlefield from view. He had never felt so alive, so aware, in his entire life.

They were still fighting, but they had their right flank hopelessly encircled. A dozen Fimbrian pike tercios there had gone into square and were completely surrounded, a sea of the enemy breaking against the grim pike points and falling back, the Fimbrian formation as perfect as though it were practising drill on a parade ground. In the centre, the Fimbrians and Torunnans were close to being overwhelmed. Their line had given ground, like a bow bending, and was now concave. Soon, it would break, and the western armies would be split in two. Only on the left, scarcely half a mile from where Corfe’s men were forming up on the ridge, was there any hope.

The Merduks on the left still had not manned the crest of the hill, and the Cathedrallers spread out along it in battle-line, four horses deep. Corfe could see some of the enemy below pointing at the newly arrived cavalry on the hilltop, but they would also see the Merduk armour they wore. He had a few minutes on his side.

The Cathedrallers were in position. A line of horsemen six hundred yards long, four ranks deep, completely silent, spectators of the vast carnage in the valley below them. Their scarlet armour gleamed in the thin sunlight, their banner flapped in the raw wind. Some of the enemy were becoming worried now about the motionless cavalry on the hill. A few hundred men had spread out into skirmish-line to counter any move round the Merduk right flank.

Corfe cantered over to Andruw and put out his hand. “Good luck, Haptman. If we don’t meet again, it’s been an honour serving with you.”

At that, Andruw grinned, gripping Corfe’s iron gauntlet in his own. “We have seen some sights, Corfe, haven’t we?”

Corfe took up the position he had assigned for himself in the middle of the front rank. He turned to his trumpeter. “Cerne, sound me the charge.”

Cerne, a heavily tattooed savage who would gladly have died for his colonel, raised his horn to his lips and blew the five-note hunting call of his own hills. Corfe drew out John Mogen’s sword, and it flashed like a quiver of summer lightning above his head. Then he kicked his mount into motion, whilst around him the line began to move, the ground shook at the thunder of over five thousand hooves, and the battle-paean of the tribes issued from a thousand throats.

T HE Merduks in the valley looked up, and the Torunnans and Fimbrians who were fighting their desperate battle for survival saw a long line of cavalry come raging down from the hilltop like a scarlet avalanche. One thousand two hundred heavy horses carrying men in red iron, their lances a limbless forest against the sky, and that terrible, barbaric battle-hymn roaring down with them.

They sped into a gallop, their lines separating out, and the wicked lances came down from the vertical. The Merduk skirmishers took one look at that looming juggernaut, and began to run.

The first rank of the Cathedrallers rode them down, spearing them through their spines and galloping on. Half a dozen of the horsemen went down, their mounts tripping on the broken ground, but they closed the gaps and kept coming. The main Merduk formations below frantically tried to change their facings to meet this new, unlooked-for enemy clad in their own armour but glowing red as fresh blood and singing in some barbaric tongue. A regiment of Hraibadar arquebusiers stood to fire a volley, but the approaching maelstrom was too much for some of them to bear, and they ran also. Their formation was scrambled, even as the first rank of the Cathedrallers smashed into them.

The big horses rode down the Merduks as though they were a line of rabbits, and the terrible lances of the riders speared scores in the first clash. Horses went down, cart-wheeling, screaming, crushing friend and foe alike, but the charge’s momentum was too powerful to stop. They rode on, and behind them came the second rank, and the third, and the fourth. More horses falling, brought down by the corpses underfoot, their riders flung through the air to be trampled by the ranks behind them. Corfe lost sixty men in the first thirty seconds, but the Merduks died by the shrieking hundred.
