A lull followed the first onslaught. The Crusaders withdrew, not in shame but in calculation. Salim used the respite to move his specialized units—scouts who could vanish into the dunes, flamethrowers who could turn a narrow passage into a tongue of fire, and a handful of mercenaries armed with axes and bitter smiles—into new positions. He considered his supplies: grain, oil, water. He knew every sack, every amphora; every resource was a statistic that breathed.

He moved past the stables where a tired warhorse stamped and snorted, past the smith's open door where a ring of embers painted faces gold. The archers had already taken their places along the crenellations, wrapped in cloth and bone-cold resolve. Salim's men were each measured by the same rules he'd always used: by what they could hold, what they could carry into the fight, and the small mercies the world allowed them—quivers, spears, a single clay of water. He knew the names the crusaders gave to enemy types—"skirmisher," "pikeman," "flaming arrows"—but on the walls of Qasr al-Ahmar, there were only friends and the promise of tomorrow.

At dawn, the first horns sounded, a low, iron-sounded insistence across the dunes. Dust rose in waves; banners stitched with the cross broke the skyline. The Crusader scout-line rode forward with the brittle assurance of men who had never seen these towers up close. Salim watched them through a slit of stone and smiled without pleasure. Their armor flashed too cleanly, their discipline too sharp. They would learn that sand dulled both.

On the second day, the Crusaders tested the southern walls. A line of pikemen advanced with the slow, methodic patience of men who believed that any door could be worn open if you pushed and pushed. They were met by the spears—Salim had drilled his men to anchor; a spearwall could collapse a hole in momentum, and for long stretches momentum was what the Crusaders depended on. The pikes pushed. The spears sturdied. Men on both sides learned to count breaths to fear, rather than to the sun.

Yet even when the defenders tasted victory, the siege crafts continued to evolve. The Crusaders brought in fire pots, slow-burning ropes of pitch designed to climb and scorch. Salim's men turned the city into a calculus of risk—wet cloth, buckets of cooled oil, vigilant patrols on the roofs. The night they tried to set the western gate alight, the defenders countered with a torrent of water and the new addition of sand-stuffed sacks. Flames collapsed; the gate, charred, stood.

As the siege dragged into nights, personalities hardened into archetypes. A Crusader commander in a pale helm rode like a metronome—predictable, relentless. He sent in waves: light cavalry to probe, knights to hammer, engineers to gouge. Salim's scouts danced around them at dusk, harrying supply lines and pulling back like ghosts. At one point, a small band of desert skirmishers slipped out and burned the Crusaders' siege engine before dawn, the flames snatching at polished timbers. The knights cursed the sky, certain the desert itself had become a conspirator.

The final day was a blur of sun and iron. The Crusader commander attempted one last gamble: concentrate every remaining siege engine and every man of weight, let the bowmen of Qasr al-Ahmar tire to their last string, and then send in the knights for a decisive push. Salim accepted the choice the world had given him—fight the engines, spare the men when possible, and force the decisive moment before numbers became meaning.
