Gorst put down his pen, frowning at a tiny cut he had somehow acquired on the very tip of his forefinger where it rendered every slightest task painful. He blew gently over the letter until every gleam of wet ink had turned dry black, then folded it, running his one unbroken nail slowly along it to make the sharpest of creases. He took up the stick of wax, tongue pressed into the roof of his mouth. His eyes found the candle flame, twinkling invitingly in the shadows. He looked at that spark of brightness as a man scared of heights looks at the parapet of a great tower. It called to him. Drew him. Made him dizzy with the delightful prospect of self-annihilation. Like that, and this shameful unpleasantness that I laughingly call a life could all be over. Only seal it, and send it, and wait for the storm to break.

Then he sighed, and slid the letter into the flame, watched it slowly blacken, crinkle, dropped the last smouldering corner on the floor of his tent and ground it under his boot. He wrote at least one of these a night, savage punctuation points between rambling sentences of trying to force himself to sleep. Sometimes he even felt better afterwards. For a very short while.

He frowned up at a clatter outside, then started at a louder crash, the gabble of raised voices, something in their tone making him reach for his boots. Many voices, then the sounds of horses too. He snatched up his sword and ripped aside his tent flap.

Younger had been sitting outside, tapping the day’s dents out of Gorst’s armour by lamplight. He was standing up now, craning to see, a greave in one hand and the little hammer in the other.

‘What is it?’ Gorst squeaked at him.

‘I’ve no— Woah!’ He shrank back as a horse thundered past, flicking mud all over both of them.

‘Stay here.’ Gorst put a gentle hand on his shoulder. ‘Stay out of danger.’ He strode from his tent and towards the Old Bridge, tucking his shirt in with one hand, sheathed long steel gripped firmly in the other. Shouts echoed from the darkness ahead, lantern beams twinkling, glimpses of figures and faces mixed up with the after-image of the candle flame still fizzing across Gorst’s vision.

A messenger jogged from the night, breathing hard, one cheek and the side of his uniform caked with mud. ‘What’s happening?’ Gorst snapped at him.

‘The Northmen have attacked in numbers!’ he wheezed as he laboured past. ‘We’re overrun! They’re coming!’ His terror was Gorst’s joy, excitement flaring up his throat so hot it was almost painful, the petty inconveniences of his bruises and aching muscles all burned away as he strode on towards the river. Will I have to fight my way across that bridge for the second time in twelve hours? He was almost giggling at the stupidity of it. I cannot wait.

Some officers pleaded for calm while others ran for their lives. Some men searched feverishly for weapons while others threw them away. Every shadow was the first of a horde of marauding Northmen, Gorst’s palm itching with the need to draw his sword, until the tricking shapes resolved themselves into baffled soldiers, half-dressed servants, squinting grooms.
