The first clash was an affair of senses more than bodies: arrows that hummed like trapped wasps, the soft, terrifying thump of boulder against parapet. The trebuchet flung a mass that shattered a corner of the outer wall; debris like pale rain fell into the courtyard. Salim ordered his engineers into the breach, and they moved with the quiet competence of men who had long ago made friends with ruin. The archers answered with long strings of fire, and the crusaders' shields wavered where they had once seemed steady.
