Michael grinned and finished off the food. ‘Well, he won’t be needing it, will he?’

Saladin reached for the flask that contained the last of yesterday’s water. There was hardly any left. He felt unreasonably resentful that a third of it had been wasted on a man now dead.

They sat without speaking.

When he had taken the Cross - he wore it proudly on his sleeve even now - and volunteered for Fernando’s army, Saladin had joined a company formed from many nations, Christian warriors drawn here from across Europe by the Pope’s granting of crusader indulgences - that and the chance to liven up your life by cracking a few Muslim heads. Hanse and Michael were typical, Hanse, blond and a bit frail, from the Low Countries, Michael from England.

It had been curious for Saladin to come up against the Moorish armies, the elite warriors with their quilted light armour, the hard-eyed horsemen from the desert. They were not much like the Saracen troops he had witnessed in the Outremer. Brother Thomas had told him that the Moors of Spain had absorbed the traditions of those who went before them; there were echoes of the post-Roman Visigoths in their cavalry and their colour.

But there had been no serious fighting for months, not since the spring when the siege had been set. There had been deaths among Fernando’s forces, a steady stream of fatalities from drought, accident, and especially the plagues that coursed through the polyglot army. It didn’t matter much to the generals, Michael said. There were always more volunteers willing to come and join an army on the brink of victory, trickling here from across Spain, indeed across Christendom. And a smart general always factored in the likelihood of losing a proportion of his army to disease. You planned for it, said Michael.

It wasn’t really a surprise that Hanse was the first of the three of them to succumb, for he had fried in the Spanish sun. Michael, though, had darkened, his face turning leathery. Saladin wondered if he had a bit of Trojan blood in him, for it was said that it had been Trojans who were the first to colonise England.

‘He had been talking of joining King Louis,’ Michael said now. ‘Hanse, I mean.’ King Louis of France was generally believed to be the most pious and accomplished crusader king since Richard the Lionheart. ‘Louis is sailing about now, for Cyprus, then on to Egypt.’

‘He should have gone,’ Saladin said. ‘Better than this, sitting around in your own filth for month after month.’

‘Maybe. Well, the poor bastard has missed out.’

‘On what?’

‘The city, when we get into it. They know some tricks, these Saracen women.’

‘They are Moors, not Saracens.’
