The artillery also was so injudiciously placed as to be almost entirely useless. Alonso of Aragon, duke of Villahermosa and illegitimate brother of the king, was present at the siege, and disapproved of the whole arrangement. He was one of the most able generals of his time, and especially renowned for his skill in battering fortified places. He recommended that the whole disposition of the camp should be changed, and that several bridges should be thrown across the river. His advice was adopted, but slowly and negligently followed, so that it was rendered of no avail. Among other oversights in this hasty and negligent expedition, the army had no supply of baked bread, and in the hurry of encampment there was no time to erect furnaces. Cakes were therefore hastily made and baked on the coals, and for two days the troops were supplied in this irregular way.
King Ferdinand felt, too late, the insecurity of his position, and endeavored to provide a temporary remedy. There was a height near the city, called by the Moors Santo Albohacen, which was in front of the bridge. He ordered several of his most valiant cavaliers to take possession of this height and to hold it as a check upon the enemy and a protection to the camp. The cavaliers chosen for this distinguished and perilous post were the marques of Cadiz, the marques of Villena, Don Roderigo Tellez Giron, master of Calatrava, his brother the count of Urena, and Don Alonso de Aguilar. These valiant warriors and tried companions-in-arms led their troops with alacrity to the height, which soon glittered with the array of arms, and was graced by several of the most redoubtable pennons of warlike Spain.
Loxa was commanded at this time by an old Moorish alcayde whose daughter was the favorite wife of Boabdil. The name of this Moor was Ibrahim Ali Atar, but he was generally known among the Spaniards as Alatar. He had grown gray in border warfare, was an implacable enemy of the Christians, and his name had long been the terror of the frontier. Lord of Zagra and in the receipt of rich revenues, he expended them all in paying scouts and spies and maintaining a small but chosen force with which to foray into the Christian territories; and so straitened was he at times by these warlike expenses that when his daughter married Boabdil her bridal dress and jewels had to be borrowed. He was now in the ninetieth year of his age, yet indomitable in spirit, fiery in his passions, sinewy and powerful in frame, deeply versed in warlike stratagem, and accounted the best lance in all Mauritania. He had three thousand horsemen under his command, veteran troops with whom he had often scoured the borders, and he daily expected the old Moorish king with reinforcements.
Old Ali Atar had watched from his fortress every movement of the Christian army, and had exulted in all the errors of its commanders: when he beheld the flower of Spanish chivalry glittering about the height of Albohacen, his eye flashed with exultation. "By the aid of Allah," said he, "I will give those pranking cavaliers a rouse."
Ali Atar privately and by night sent forth a large body of his chosen troops to lie in ambush near one of the skirts of Albohacen. On the fourth day of the siege he sallied across the bridge and made a feint attack upon the height. The cavaliers rushed impetuously forth to meet him, leaving their encampment almost unprotected. Ali Atar wheeled and fled, and was hotly pursued. When the Christian cavaliers had been drawn a considerable distance from their encampment, they heard a vast shout behind them, and, looking round, beheld their encampment assailed by the Moorish force which had been placed in ambush, and which had ascended a different side of the hill. The cavaliers desisted from the pursuit, and hastened to prevent the plunder of their tents. Ali Atar, in his turn, wheeled and pursued them, and they were attacked in front and rear on the summit of the hill. The contest lasted for an hour; the height of Albohacen was red with blood; many brave cavaliers fell, expiring among heaps of the enemy. The fierce Ali Atar fought with the fury of a demon until the arrival of more Christian forces compelled him to retreat into the city.
