Ahead, on the flat plain, the army of Stone continued its advance, the columns smoothly melding, the formation changing. Closer now, and Bran could see sunlight glinting on their helms and the great, rectangular shields they carried. Their formation was – as he had hoped – the Classic Five, ten ranks deep along a wide front, their flanks defended by six Panthers, three on either side, stretching back down the plain and creating three sides of a square. Between the defensive lines Bran saw the Stone archers bringing up the rear. He gauged their numbers to be around a thousand.

Scanning the enemy force, Bran calculated their numbers. He reckoned Jasaray had brought ten Panthers, plus his archers – thirty-one thousand fighting men. That meant he had left two Panthers to defend the night fortress, allowing himself room to withdraw to a position of safety should the battle go against him. Against him Bran had marshalled just over forty thousand tribesmen, many of these untried in major battles. Despite the numerical superiority the reality was that Jasaray had the stronger force. The real strength of the Keltoi army lay in the ten thousand Iron Wolves, eight thousand heavy infantry, and three thousand Horse Archers. These were battle-hardened, well-trained and disciplined fighters. The rest were brave tribesmen, who, left to their own devices, would be cut to pieces by the soldiers of Stone within an hour.

The wind changed, and the sound of drumbeats echoed across the field as the Stone army continued its march towards the Keltoi centre. Bran signalled his archers to draw up behind the front lines. Hundreds of Rigante bowmen ran forward.

Three hundred yards away now and a trumpet sounded in the enemy ranks. The soldiers of Stone halted their march, the formation changing again. Bran's heart sank, for the Stone line spread out into the open fighting square. Then they advanced once more. Bran's mind raced. They could still envelop the enemy, but to what advantage? Their only hope had been to compress them, destroying their ability to manoeuvre. This new formation was flexible, and Bran could see two Panthers in reserve at the centre, ready to plug any gaps that might develop.

Two hundred yards and Bran could now see the figure of Jasaray at the centre of the enemy square. The emperor was wearing a simple unadorned breastplate of iron, and an old battered helm. He was walking with his hands clasped behind his back, and chatting to the officer beside him.

One hundred yards, and the drums picked up their beat. The advance quickened. Bran could feel the tension in the men around him, the beginnings of fear.

'Death to Stone!' bellowed Bran, drawing his sword and holding it high. A huge cry went up from the Keltoi, a roaring, releasing wall of sound that swept over the advancing ranks.

Fifty yards. Now Bran could see individual faces. 'Archers!' he shouted.
