The Egyptian archers were drawn up behind them, ready to move forward through their ranks or retreat again, as the vagaries of the battle called for each differing tactic. They raised their recurved bows on high and cheered Pharaoh. 'Tamose! Egypt and Tamose!'

  Pharaoh wore the blue war crown, with the golden circlet of the uraeus around his brow, the heads of the vulture and the cobra of the two kingdoms entwined, their jewelled eyes glittering. He returned their salute with the bare blade of the blue sword held high.

  We wheeled around our own left flank, and before we started back, Memnon stopped me with a hand on my shoulder. For a short while we looked back over the field. The Hyksos were moving forward already. Their front line was twice the length of our own.

  'From your own treatise, Tata,' he quoted, ' "A circumspect defence until the enemy is committed, and then the rapid and audacious attack." '

  'You have remembered the lesson well, sire.'

  'It is certain we will be outflanked, and Apachan will probably throw in his first five chariot divisions at the start.'

  'I agree with you, Mem.'

  'But we know what we have to do, don't we, Tata?' He tapped my shoulder and we started back to where our own chariots were holding in the rear.

  Remrem headed the first division, Astes had the second, and Lord Aqer the third. Newly promoted to the rank of Best of Ten Thousand, Captain Hui commanded the fourth division. Two regiments of Shilluk guarded our baggage and the spare horses.

  'Look at that old hunting dog,' Memnon nodded at Remrem. 'He is chafing to be away. By Horus, I'll teach him a little patience before this day is done.'

  We heard the horns sounding in the centre.

  'It begins now.' Memnon pointed to the front, and we saw the Hyksos chariots looming through the dust-clouds. 'Yes, Apachan has turned loose his chariots.'

  He looked back at our divisions, and Remrem raised his sword high. "The first is ready, Majesty,' he called ®agerly, but Memnon ignored him and signalled to Lord Aqer. The third division came forward in column of fours behind us, and Pharaoh led them out.

  The Hyksos chariots lumbered forward, heavy and majestic, aimed at the centre of our line. Memnon cut across in front of them, interposing our thin column between their hordes and the infantry. Then, at his signal, we wheeled into line abreast and we flew straight at them. It seemed suicidal, as futile as charging one of our frail wooden galleys at the rocks of the cataract.

  As we came together, our archers fired head-on into the Hyksos, aiming for the horses. Gaps opened in their line as the animals were brought down by our arrows, then at the last possible moment our own line dissolved like wind-driven smoke. Our drivers used their superior speed and manoeuvrability. Instead of coming into collision with the Hyksos line and being crushed beneath the juggernaut, we swerved into the gaps and raced through them. Not all our chariots escaped, and some were broken and overturned, but Lord Aqer led four out of every five of them through.

  We emerged in the rear of the Hyksos charge and spun around in a full-locked turn, re-forming the line at the gallop and again using our speed to overhaul the Hyksos, coming into them from the rear, firing our arrows into them at shortening range.

  The Hyksos chariots were designed to give protection to the crew from the front, and their archers were stationed on the footplate to fire their arrows forward. Confusion spread down their line as they tried to meet our attack from the rear. Hard-pressed, some of the drivers attempted to turn back to confront us, and they collided with the chariots alongside. Those fearsome wheel-scythes cut into the legs of the neighbouring horses, and brought them down in a screaming, whinnying tangle.

  The confusion spread among them just as the first volley of arrows from the Egyptian archers rose up over the massed ranks of Shilluk and dropped among the Hyksos. Immediately this happened, Memnon gave the order, and we wheeled away and let them run down on that palisade of sharpened staves. Half their horses were maimed or killed by those fierce points. Those who broke through were met by the Shilluk and a cloud of javelins. Struck by stake and arrow and javelin, their horses panicked, kicking and rearing in the traces.

  Those chariots that were still under control hurled themselves into the Shilluk phalanx. They met no resistance. The black ranks opened before them, allowing the horses to run through, but then they closed up behind them.

  Every one of those tall, willowy black devils was an athlete and an acrobat. They leaped up on to the footplate of the racing chariots from behind, and they stabbed and hacked at the crew with dagger and spear. They swallowed that first charge of chariots the same way a jellyfish engulfs a swift silver sardine in its myriad arms and amorphous body.

  The Hyksos spearmen were moving forward to follow up and exploit the chariot charge, but now they were exposed. Loose horses and the surviving chariots tore back into their massed ranks, and forced them to open up and let them through. For the moment they were stranded in disorder in the middle of the field, and Memnon skilfully seized the opportunity.

  Lord Aqer's horses were blown, and Memnon led them back into reserve. He and I changed teams. It was but a moment's work for the grooms to loosen the tack that coupled Rock and Chain, and to lead in a fresh team from the horses being held in reserve. We had six thousand fresh horses ready in the rear. I wondered how many Hyksos horses had escaped the Strangler, how many fresh teams they were holding.

  As we wheeled back into line, Remrem called to us desperately, 'Your Majesty! The first! Let my first division go!'

  Pharaoh ignored him and signalled to Astes. The second moved forward behind us and formed up at the trot.

  The Hyksos infantry was still tangled in the middle of the field. They had extended to overlap our shorter line, but had lost their dressing. The line was crumpled and twisted. With a general's eye, Memnon picked out the weakest point, a salient in their left flank.

  'The second division will advance. Trot-march! Forward! Pods of eight, charge!'

  We tore into the salient in the line, eight chariots abreast. Pod after pod, we crashed into them and ripped them open. Their left flank buckled, while their right still pressed forward. We had them canted across the field, their centre was shearing, and Memnon re-formed the third division at the gallop, and set them up to tear open the enemy centre.

  At the moment before we were committed to the charge, I glanced across at the city. Dust had almost obscured the range, but I glimpsed the two white flags on the summit of the Finger of Horus. It was the warning signal from my lookout posted there, and I swivelled round and looked back at the eastern fort of the city.

  'Sire!' I cried, and pointed back. The king followed my arm, and saw the first squadron of Hyksos chariots trot out from concealment behind the curve of the wall. The others followed, like a column of black warrior ants on the march.

  'Apachan is throwing in his reserves to save his infantry,' Memnon shouted, above the din of battle. 'A moment more, and he would have had us in enfilade. Well done, Tata.'

  We had to let the infantry escape, as we wheeled into line to face Apachan's chariots. We charged at each other across a field littered with smashed and overturned chariots, loose arrows and javelins, dead and wounded horses and dying men. As we came together, I stood taller on the footplate and peered ahead. There was something unusual about the run of the enemy chariots, and then it dawned upon me.

  'Sire,' I cried, 'look at the horses! They are running sick animals.' The chests of the leading teams were painted with a glistening coat of yellow mucus that streamed from their gaping mouths. Even as I watched, one of the horses coming towards us staggered and fell headlong, bringing its teammate down with it.
