The idea that this was a stratagem of the Moors soon subsided; but it was feared they might take advantage of it to assault the camp. The Marquis of Cadiz, therefore, sallied forth with three thousand horse to check any advance from the city. When they emerged from the camp they found the whole firmament illuminated. The flames whirled up in long light spires, and the air was filled with sparks and cinders. A bright glare was thrown upon the city, revealing every battlement and tower. Turbaned heads were seen gazing from every roof, and armor gleamed along the walls; yet not a single warrior sallied from the gates. The Moors suspected some stratagem on the part of the Christians, and kept quietly within their walls. By degrees the flames expired; the city faded from sight; all again became dark and quiet, and the Marquis of Cadiz returned with his cavalry to the camp. When the day dawned on the Christian camp nothing remained of that beautiful assemblage of stately pavilions but heaps of smouldering rubbish. The fire at first had been attributed to treachery, but on investigation it proved to be entirely accidental. The wary Ferdinand knew the sanguine temperament of the Moors, and hastened to prevent their deriving confidence from the night's disaster. At break of day the drums and trumpets sounded to arms, and the Christian army issued from among the smoking ruins of their camp, in shining squadrons, with flaunting banners and bursts of martial melody, as though the preceding night had been a time of high festivity instead of terror. The Moors had beheld the conflagration with wonder and perplexity. When the day broke and they looked toward the Christian camp, they saw nothing but a dark smoking mass. Their scouts came in with the joyful intelligence that the whole camp was a scene of ruin. Scarce had the tidings spread throughout the city when they beheld the Christian army advancing toward their walls. They considered it a feint to cover their desperate situation and prepare for a retreat. Boabdil had one of his impulses of valor--he determined to take the field in person, and to follow up this signal blow which Allah had inflicted on the enemy. The Christian army approached close to the city, and were laying waste the gardens and orchards, when Boabdil sallied forth, surrounded by all that was left of the flower and chivalry of Granada. There was not so much one battle as a variety of battles; every garden and orchard became a scene of deadly contest; every inch of ground was disputed, with an agony of grief and valor, by the Moors; every inch of ground that the Christians advanced they valiantly maintained; but never did they advance with severer fighting or greater loss of blood.
