'Sweet Isis, you are right. Their horses are finished before they have begun,' Memnon answered. He saw instantly what he had to do. It was the measure of his superb control that he was able to deflect a charge of his chariots once it was fully launched. At this very last moment he declined the head-on engagement.

  We opened like a flower before their charge, peeling away on either side of them, turning and running back for our own lines, drawing them on, straining their sick and gasping horses to their utmost.

  We ran before them in a tight, compact formation. Their own line began to waver and fall apart as the weaker horses broke down. Some of them fell as though struck in the head by an arrow. Others merely slowed and stopped, standing with their heads hanging, mucus pouring from their mouths in shiny golden ropes.

  Lord Aqer's own horses were almost blown by now. They had driven two furious charges without a rest. Still pursued by the remnants of Apachan's division, Memnon led them back to where Hui's fourth division was drawn up alongside Remrem and his first.

  'Pharaoh! The first is ready. Let me go! In the name of all the gods, let me go!' Remrem howled with frustration.

  Memnon hardly glanced in his direction. I turned my chariot in alongside that of Hui. A team of grooms slipped our sweat-soaked horses from the traces and led in a fresh pair. While Lord Aqer's exhausted division streamed back past us, we faced the oncoming Hyksos.

  'Are you ready, Captain Hui?' Memnon called to him, and Hui raised his bow in salute.

  'For Egypt and Tamose!' he shouted.

  'Then forward march. Charge!' Memnon laughed, and our horses jumped against the traces and we shot forward.

  There were six full divisions of Apachan's chariots scattered across the field in front of us. Half of them were broken down, with the horses fallen or drooping in the traces, suffocated and dying from the Yellow Strangler. Most of the others were reduced to a walk, the horses staggering and wheezing. However, the remaining chariots came on in good order.

  We went out to meet them face to face. In the centre of their charge rode a tall chariot, its coachwork clad in shining bronze. On the footplate stood a man so tall that he towered above his driver. He wore the high golden helmet of Hyksos royalty, and his dark beard was plaited with coloured ribbons that fluttered in the wind like pretty butterflies hovering over a flowering shrub.

  'Apachan!' Memnon challenged him. 'You are a dead man.'

  Apachan heard him, and he picked out our golden chariot. He swerved to meet us, and Memnon tapped my shoulder.

  'Lay me alongside the bearded hog. It's time for the sword, at last.'

  Apachan loosed two arrows at us as we closed. Memnon caught one on his shield. I ducked under the other, but I never lost my concentration. I was watching those terrible spinning scythes on the hubs of Apachan's wheels. They could hack my horses' legs out from under them.

  Behind me I heard the gravelly rasp as Memnon drew the blue sword from its scabbard on the side panel, and from the corner of my eye I caught the steely flash of the blade as he went on guard.

  I swung my horses' heads over, feinting to the right to confuse the Hyksos driver, but the instant we started to turn away, I changed direction again. I avoided his scythes and passed him close, then I turned in sharply behind him. With my free hand I snatched up the grappling-hook and tossed it over the side-panel of the other chariot. Now we were locked together, but I had achieved the advantage, for we lay across his stern.

  Apachan swivelled around, and aimed a sword-cut at me, but I fell to my knees under it, and Memnon gathered up the blow on his shield, then swung the blue sword. A shard of bronze curled from the edge of Apachan's weapon, sliced away by the steel, and he shouted in angry disbelief, and flung up his copper shield at the next blow.

  Apachan was a superb swordsman, but no match for my king and the blue sword. Memnon mangled his shield to strips, and then swung hard at his bronze blade, as Apachan tried to defend his head. The blue blade sheared the bronze cleanly, and Apachan was left with only the hilt in his fist.

  He opened his mouth wide and bellowed at us. The teeth in the back of his jaw were black and rotten, and his spittle blew into my face in a cloud. Memnon used that classic straight thrust to end it. He drove the point of the blue blade through Apachan's open mouth, deeply into the back of his throat. His angry bellow was drowned out by the torrent of bright blood that burst through his hairy lips.

  I cut the rope of the grappling-hook, and let the Hyksos chariot run free. The horses were out of control and they slewed away and ran down the line of locked and battling chariots. Apachan clutched at the dashboard, holding himself erect even though he was dying, and the blood spurted from his mouth and cascaded down his breastplate.

  It was a sight that struck dismay into the hearts of his charioteers. They tried to disengage their sick and staggering-horses, but we ran hub-to-hub with them and hurled our javelins into them. We followed them all the way back, until we came within range of their archers, and flocks of arrows fell around us and forced us to break off.

  'It is not over yet,' I warned Memnon, as we walked our tired horses back. 'You have broken Apachan's chariots, but you still have to deal with Beon's infantry.'

  'Take me to Kratas,' Pharaoh ordered.

  I stopped our chariot in front of the massed regiments of Shilluk, and Memnon called across to Kratas, 'What heart, my Lord?'

  'I fear, sire, that my fellows will fall asleep if you cannot find a little work for us to do.'

  'Then let us hear a tune from them as you take them forward to seek employment.'

  The Shilluk began their advance. They moved with a curious shuffling gait, and every third pace they stamped in unison with a force that made the ground jump beneath their horny bare feet. They sang in those deep, melodious African voices, a sound like a swarm of angry black bees, and they drummed their spears upon their rawhide shields.

  The Hyksos were disciplined and brave, they could not have conquered half the world if they had not been so. We had smashed up their chariots, but they stood to meet Kratas' advance behind a wall of bronze shields.

  The two armies came together like fighting temple bulls. The black and the white bulls locked horns and fought it out breast-to-breast and spear-to-spear.

  While the two armies of foot-soldiers mauled each other, Pharaoh held back his chariots, using them with skill and daring only when there was an opening or a weakness in the enemy positions. When a pocket of the Hyksos infantry was isolated on the left, he sent in Aqer's division, and annihilated them with two swift charges. When Lord Beon tried to send reinforcements forward to assist his beleaguered front, Pharaoh despatched Astes with five hundred chariots to frustrate him.

  The Hyksos rallied every one of their remaining chariots, and every one of their horses that could still stand, and threw them against our right. Memnon sent Hui and Astes out to meet them, and to break up their attack. He left Remrem cursing and pleading and stamping up and down beside his chariot, and ignored his pleas.

  Pharaoh and I circled the fighting in the golden chariot, watching each shift and change in the conflict. He pushed in his reserves in exactly those places where they were most needed, and with the timing and anticipation that can never be taught or learned. It was as though the pulse and the tempo of the battle beat in his heart, and he sensed it in his blood.

  Always I looked for Kratas in the thick of it. Many times I lost him, and I dreaded that he was down, but then his helmet showed again with the ostrich-feather plume cut away, and the bronze splattered with his own blood and the blood of other men.
