The Moorish army entered the Christian frontier by forced marches, hastily ravaging the country, driving off the flocks and herds, and making captives of the inhabitants. They pressed on furiously, and made the latter part of their march in the night, to elude observation and come upon Lucena by surprise. Boabdil was inexperienced in warfare, but had a veteran counsellor in his old father-in-law; for Ali Atar knew every secret of the country, and as he prowled through it his eye ranged over the land, uniting in its glare the craft of the fox with the sanguinary ferocity of the wolf. He had flattered himself that their march had been so rapid as to outstrip intelligence, and that Lucena would be an easy capture, when suddenly he beheld alarm-fires blazing upon the mountains. “We are discovered,” said he to Boabdil; “the country will be up in arms; we have nothing left but to strike boldly for Lucena: it is but slightly garrisoned, and we may carry it by assault before it can receive assistance.” The king approved of his counsel, and they marched rapidly for the gate of Lucena. CHAPTER XV. HOW THE COUNT DE CABRA SALLIED FORTH FROM HIS CASTLE IN QUEST OF KING BOABDIL. Don Diego de Cordova, count of Cabra, was in the castle of Vaena, which, with the town of the same name, is situated on a lofty sun-burnt hill on the frontier of the kingdom of Cordova and but a few leagues from Lucena. The range of mountains of Horquera lies between them. The castle of Vaena was strong and well furnished with arms, and the count had a numerous band of vassals and retainers; for it behooved the noblemen of the frontiers in those times to be well prepared with man and horse, with lance and buckler, to resist the sudden incursions of the Moors. The count of Cabra was a hardy and experienced warrior, shrewd in council, prompt in action, rapid and fearless in the field. He was one of the bravest of cavaliers for an inroad, and had been quickened and sharpened in thought and action by living on the borders. On the night of the 20th of April, 1483, the count was about to retire to rest when the watchman from the turret brought him word that there were alarm-fires on the mountains of Horquera, and that they were made on the signal-tower overhanging the defile through which the road passes to Cabra and Lucena. The count ascended the battlement and beheld five lights blazing on the tower--a sign that there was a Moorish army attacking some place on the frontier. The count instantly ordered the alarm-bells to be sounded, and despatched couriers to rouse the commanders of the neighboring towns. He called upon his retainers to prepare for action, and sent a trumpet through the town summoning the men to assemble at the castle-gate at daybreak armed and equipped for the field.
