‘Which way, Corporal Tunny?’ asked Worth, doubled up around his guts.

‘Stick to the grassy bits, the guide said!’ Though there wasn’t much around that an honest man could’ve called grass. Not that there were many honest men around either. ‘Have you got a rope, boy?’ he asked Yolk, struggling through the mulch beside him, a long smear of mud down his freckled cheek.

‘Left ’em with the horses, Corporal.’

‘Of course. Of course we bloody did.’ By the Fates, how Tunny wished he’d been left with the horses. He took one step and cold water rushed over the top of his boot like a clammy hand clamping around his foot. He was just setting up to have a proper curse at that when a shrill cry came from behind.

‘Ah! My boot!’

Tunny spun round. ‘Keep quiet, idiot!’ Totally failing to keep quiet himself. ‘The Northmen’ll hear us in bloody Carleon!’

But Klige wasn’t listening. He’d strayed well away from the rushes and left one of his boots behind, sucked off by the bog. He was wading out to get it, sliding in up to his thighs. Yolk snickered at him as he started delving into the slime.

‘Leave it, Klige, you fool!’ snapped Tunny, floundering back towards him.

‘Got it!’ The bog made a squelching suck as Klige dragged his boot free, looking like it was caked in black porridge. ‘Whoa!’ He lurched one way, then the other. ‘Whoa!’ And he was in up to his waist, face flipped from triumph to panic in an instant. Yolk snickered again, then suddenly realised what was happening.

‘Who’s got a rope?’ shouted Lederlingen. ‘Someone get a rope!’ He floundered out towards Klige, grabbing hold of the nearest piece of tree, a leafless twig thrust out over the mire. ‘Take my hand! Take my hand!’

But Klige was panicking, thrashing around and only working himself deeper. He went down with shocking speed, face tipped back, only just above the level of the filth, a big black leaf stuck across one cheek.

‘Help me!’ he squealed, stretching fingers still a good stride short of Lederlingen’s. Tunny slopped up, shoving the flagstaff out towards Klige. ‘Help murghhh—’ His bulging eyes rolled towards Tunny, then they were lost, his floating hair vanished, a few bubbles broke on the foetid surface, and that was it. Tunny poked at the mush uselessly, but Klige was gone. Aside from his rescued boot, floating slowly away, no trace he’d ever existed.

They struggled the rest of the way in silence, the other recruits looking stunned, Tunny with his jaw furiously clenched, all sticking to the tumps of yellow weed as close as new foals to their mothers. Soon enough the ground started to rise, the trees turned from twisted swamp monsters to firs and oaks. Tunny leaned the filthy standard against a trunk and stood, hands on hips. His magnificent boots were ruined.

‘Shit!’ he snarled. ‘Fucking shit!’

Yolk sank down in the muck, staring into nowhere, white hands trembling. Lederlingen licked his pale lips, breathing hard and saying nothing. Worth was nowhere to be seen, though Tunny thought he could hear someone groaning in the undergrowth. Even the drowning of a comrade couldn’t delay the working of that lad’s troublesome bowels. If anything it had made them accelerate. Forest walked up, caked to the knees in black mud. They all were caked, daubed, spattered with it, and Tunny in particular.
