Jezal, swaying numbly back and forward, almost felt sorry for the Gurkish. Their numbers might have been impressive from a distance, but close up these men were evidently auxiliaries, thrown forward into the crater as a forlorn hope. They were scrawny, dirty, helplessly disorganised, lightly armed and barely armoured. Many of them, he realised, looked extremely scared. Gorst hacked his way impassively through them like a bull through a flock of sheep, growling as his scything steels opened gaping wounds with sickening fleshy sounds. Other armoured figures crowded in after him, shoving with shields, chopping with their bright swords, clearing a bloody space in the Gurkish crowd.

Gorst's hand slid under Jezal's armpit and dragged him backwards, his heels kicking at the rubble. He was vaguely aware that he had dropped his sword somewhere, but it seemed foolish to go looking for it now. Some beggar would no doubt receive a priceless windfall while he hunted among the bodies, later. Jezal saw a Knight Herald still mounted, an outline with a winged helmet in the choking dust, his long axe chopping around him.

He was half-carried back, out of the press. Some of the city's regular defenders had regrouped, or were coming in from other parts of the walls. Men with steel caps started to kneel at the lip of the crater, shooting flatbows down into the heaving mass of Gurkish in the bottom, all tangled up with the mud and the rubble. Others dragged up a cart and tipped it onto its side to form a temporary rampart. A Gurkish soldier sobbed as he was cut open, tumbled over the ragged edge of the crater and back down into the mud. More Union flatbows appeared at the edge of the square, more spears. Barrels, masonry, broken spars came with them until an improvised barricade was built up all across the wide gap in Arnault's wall, bristling with men and weapons.

Peppered with bolts and chunks of fallen masonry, the Gurkish faltered, then fell back, scrambling through the debris to their side of the crater and up towards safety, leaving the bottom strewn with corpses.

'To the Agriont, your Majesty,' said Gorst. 'At once.'

Jezal made no effort to resist. He had done more than enough fighting for today.

Something strange was happening in the Square of Marshals. Labourers were working at the paving stones with pick and chisel, digging up shallow trenches, apparently at random. Smiths sweated at temporary forges, pouring iron into moulds, lit by the glow of molten metal. The din of clanging hammers and crashing stone was enough to make Jezal's teeth hurt, yet somehow the voice of the First of the Magi managed to be louder still.

'No! A circle, dunce, from here to there!'
