The sergeant raised the crossbow to his shoulder, aimed towards an upper windowThere were heavy infantry among them now, and Bottle saw Taffo, from Mosel's squad, wading into a crowd of warriors, now ten paces from the building – from Strings's target-as the crossbow thunked, the misshapen quarrel flying out, up, into the maw of the window.

Bottle threw himself flat, arms covering his headThe upper floor of the building exploded, huge sections of wall bulging, then crashing down into the street. The cobbles jumped beneath Bottle.

Someone rolled up against him and he felt something flop heavy and slimy onto his forearm, twitching and hot. A sudden reek of bile and faeces.

The patter of stones, piteous moans, the lick of flames. Then another massive crash, as what remained of the upper poor collapsed into the level below. The groan of the nearest wall preceded its sagging dissolution. Then, beyond the few groans, silence.

Bottle lifted his head. To find Corporal Harbyn lying beside him. The lower half of the soldier's body was gone, entrails spilled out.

Beneath the helm's ridge, eyes stared sightlessly. Pulling away, Bottle leaned back on his hands and crabbed across the rock-strewn street. Where Taffo had been fighting a mob of warriors, there was now nothing but a heap of rubble and a few dust-sheathed limbs jutting from beneath it, all motionless.

Koryk moved past him, stabbing down at stunned figures with his sword.

Bottle saw Smiles cross the half-Seti's path, her two knives already slick with blood.

Bodies in the street. Figures slowly rising, shaking their heads, spitting blood. Bottle twisted round onto his knees, dipped his head, and vomited onto the cobbles.

'Fiddler – you bastard!'

Coughing, but stomach quiescent for the moment, Bottle looked over to see Sergeant Mosel advancing on Strings.

'We had them! We were rushing the damned building!'

'Then rush that one!' Strings snapped, pointing at the tenement on the other side of the street. 'They just been knocked back, that's all – any moment now and another rain of arrows-'

Cursing, Mosel gestured at the three heavies left – Mayfly, Flashwit and Uru Hela – and they lumbered into the building's doorway.

Strings was fitting another quarrel into his crossbow, this one loaded with a sharper. 'Balgrid! Who's left in your squad?'

The portly mage staggered over. 'What?' he shouted. 'I can't hear you!

What?'

'Tavos Pond!'

'Here, Sergeant. We got Maybe, uhm, Balgrid – but he's bleeding out from his ears. Lutes is down, but he should live – with some healing.

We're out of this-'

'To Hood you are. Pull Lutes clear – there's a squad coming up – the rest of you are with me-'

'Balgrid's deaf!'

'Better he was mute – we got hand signals, remember? Now remind the bastard of that! Bottle, help Tarr out. Cuttle, take Koryk to that corner up ahead and wait there for us. Smiles, load up on quarrels – I want that weapon of yours cocked and your eyes sharp on everything from rooftops on down.'

Bottle climbed to his feet and made his way to where Tarr was struggling to clamber free of rubble – a part of the wall had fallen on him, but it seemed his armour and shield had withstood the impact.

Lots of swearing, but nothing voiced in pain. 'Here,' Bottle said, ' give me your arm-'

'I'm fine,' the corporal said, grunting as he kicked his feet clear.

He still gripped his shortsword, and snagged on its tip was a hairy piece of scalp, coated in dust and dripping from the underside. 'Look at that,' he said, gesturing up the street with his sword, 'even Cuttle's shut up now.'

'Fid had no choice,' Bottle said. 'Too many arrows coming down-'

'I ain't complaining, Bottle. Not one bit. See Borduke go down? And Hubb? That could've been us, if we'd reached here first.'

'Abyss take me, I hadn't thought of that.'

He glanced over as a squad of medium infantry arrived – Sergeant Cord' s – Ashok Regiment and all that. 'What in Hood's name happened?'

'Ambush,' Bottle said. 'Sergeant Strings had to take a building down.

Cusser.'

Cord's eyes widened. 'Bloody marines,' he muttered, then headed over to where Strings crouched. Bottle and Tarr followed.

'You formed up again?' Cord asked their sergeant. 'We're bunching up behind you-'

'We're ready, but send word back. There'll be ambushes aplenty. Leoman means us to buy every street and every building with blood. Fist Keneb might want to send the sappers ahead again, under marine cover, to drop buildings – it's the safest way to proceed.'

Cord looked round. 'Safest way? Gods below.' He turned. 'Corporal Shard, you heard Fid. Send word back to Keneb.'

'Aye, Sergeant.'

'Sinn,' Cord added, speaking to a young girl nearby, 'put that knife away – he's already dead.'

She looked up, even as her blade cut through the base of the dead warrior's right index finger. She held it up for display, then stuffed it into a belt pouch.

'Nice girl you got there,' Strings said. 'Had us one of those, once.'

'Shard! Hold back there! Send Sinn with the message, will you?'

'I don't want to go back!' Sinn shouted.

'Too bad,' Cord said. Then, to Strings: 'We'll link up with Mosel's heavies behind you.'

Strings nodded. 'All right, squad, let's try out the next street, shall we?'

Bottle swallowed back another surge of nausea, then he joined the others as they scrambled towards Koryk and Cuttle. Gods, this is going to be brutal.

Sergeant Gesler could smell it. Trouble in the night. Unrelieved darkness from gaping windows, yawning doorways, and on flanking streets, where other squads were moving, the sounds of pitched battle.

Yet, before them, no movement, no sound – nothing at all. He raised his right hand, hooked two fingers and made a downward tugging motion.

Behind him he heard boots on the cobbles, one padding off to his left, the other to his right, away, halting when the soldiers reached the flanking buildings. Truth on his left, Pella on his right, crossbows out, eyes on opposite rooftops and upper windows.

Another gesture and Sands came up from behind to crouch at his side. '

Well?' Gesler demanded, wishing for the thousandth time that Stormy was here.

'It's bad,' Sands said. 'Ambushes.'

'Right, so where's ours? Go back and call up Moak and his squad, and Tugg's – I want those heavies clearing these buildings, before it all comes down on us. What sappers we got with us?'

'Thom Tissy's squad's got some,' Sands said. 'Able, Jump and Gupp, although they just decided to become sappers tonight, a bell or so ago.'

'Great, and they got munitions?'

'Aye, Sergeant.'

'Madness. All right. Get Thom Tissy's squad up here, too. I heard one cusser go off already – might be the only way to do this.'

'Okay, Sergeant. I'll be right back.'

Under-strength squads and a night engagement in a strange, hostile city. Had the Adjunct lost her mind?

Twenty paces away, Pella crouched low, his back against a mud-brick wall. He thought he'd caught movement in a high window opposite, but he couldn't be certain – not enough to call out the alarm. Might well have been a curtain or something, plucked by the wind.

Only… there ain't much wind.

Eyes fixed on that particular window, he slowly raised his crossbow.

Nothing. Just darkness.

Distant detonations – sharpers, he guessed, somewhere to the south.

We're supposed to be pushing in hard and fast, and here we are, bogged down barely one street in from the breach. Gesler's gotten way too cautious, I think.

He heard the clank of weapons, armour and the thud of footfalls as more squads came up. Flicking his gaze away from the window, he watched as Sergeant Tugg led his heavies towards the building opposite. Three soldiers from Thom Tissy's squad padded up to the doorway of the building Pella was huddled against. Jump, Gupp and Able. Pella saw sharpers in their hands – and nothing else. He crouched lower, then returned his attention to the distant window, cursing under his breath, waiting for one of them to toss a grenado in through the doorway.
