Suddenly the system of warfare was changed. We experienced no more assaults; and by night and day we continued our labours unimpeded. Stranger still, when the troops advanced near the city, the walls were vacant, and no cannon was pointed against the intruders. When these circumstances were reported to Raymond, he caused minute observations to be made as to what was doing within the walls, and when his scouts returned, reporting only the continued silence and desolation of the city, he commanded the army to be drawn out before the gates. No one appeared on the walls; the very portals, though locked and barred, seemed unguarded; above, the many domes and glittering crescents pierced heaven; while the old walls, survivors of ages, with ivy-crowned tower and weed-tangled buttress, stood as rocks in an uninhabited waste. From within the city neither shout nor cry, nor aught except the casual howling of a dog, broke the noonday stillness. Even our soldiers were awed to silence; the music paused; the clang of arms was hushed. Each man asked his fellow in whispers, the meaning of this sudden peace; while Raymond from an height endeavoured, by means of glasses, to discover and observe the stratagem of the enemy.
