Don Fadrique had received instructions from the politic Ferdinand to aid the youthful monarch in all his contests with his uncle. He advanced with a body of troops near to Granada. The moment Boabdil discerned, from the towers of the Albaycin, the Christian banners and lances winding round the base of the mountain of Elvira, he sallied forth to meet them, escorted by a squadron of Abencerrages under Aben Comixa. El Zagal, who was equally on the alert, and apprised that the Christian troops came in aid of his nephew, likewise sallied forth and drew up his troops in battle array. Don Fadrique, wary lest some treachery should be intended, halted among some plantations of olives, retained Boabdil by his side, and signified his wish that Aben Comixa would advance with his squadron and offer battle to the old king. The provocation was given, but El Zagal maintained his position. He threw out some light parties, however, which skirmished with the Abencerrages of Aben Comixa, after which he caused his trumpets to sound a recall, and retired into the city, mortified, it is said, that the Christian cavaliers should witness these fratricidal discords between true believers.
Don Fadrique, still distrustful, drew off to a distance, and encamped for the night near the bridge of Cabillas.
Early in the morning a Moorish cavalier with an escort approached the advance guard, and his trumpets sounded a parley. He craved an audience as an envoy from El Zagal, and was admitted to the tent of Don Fadrique. El Zagal had learnt that the Christian troops had come to aid his nephew, and now offered to enter into an alliance with them on terms still more advantageous than those of Boabdil. The wary Don Fadrique listened to the Moor with apparent complacency, but determined to send one of his most intrepid and discreet cavaliers, under the protection of a flag, to hold a conference with the old king within the very walls of the Alhambra. The officer chosen for this important mission was Don Juan de Vera, the same stanch and devout cavalier who in times preceding the war had borne the message from the Castilian sovereigns to old Muley Abul Hassan demanding arrears of tribute. Don Juan was received with great ceremony by the king. No records remain of his diplomatic negotiations, but they extended into the night, and, it being too late to return to camp, he was sumptuously lodged in an apartment of the Alhambra. In the morning one of the courtiers about the palace, somewhat given to jest and raillery, invited Don Juan to a ceremony which some of the alfaquis were about to celebrate in the mosque of the palace. The religious punctilio of this most discreet cavalier immediately took umbrage at what he conceived a banter. "The servants of Queen Isabella of Castile," replied he, stiffly and sternly, "who bear on their armor the cross of St. Jago, never enter the temples of Mahomet but to level them to the earth and trample on them.''
The Moslem courtier retired somewhat disconcerted by this Catholic but not very courteous reply, and reported it to a renegado of Antiquera. The latter, eager, like all renegados, to show devotion to his newly-adopted creed, volunteered to return with the courtier and have a tilt of words with the testy diplomatist. They found Don Juan playing a game of chess with the alcayde of the Alhambra, and took occasion to indulge in sportive comments on some of the mysteries of the Christian religion. The ire of this devout knight and discreet ambassador began to kindle, but he restrained it within the limits of lofty gravity. "You would do well," said he, "to cease talking about what you do not understand." This only provoked light attacks of the witlings, until one of them dared to make some degrading and obscene comparison between the Blessed Virgin and Amina, the mother of Mahomet. In an instant Don Juan sprang to his feet, dashed chess-board and chess-men aside, and, drawing his sword, dealt, says the curate of los Palacios, such a "fermosa cuchillada" (such a handsome slash) across the head of the blaspheming Moor as felled him to the earth. The renegado, seeing his comrade fall, fled for his life, making the halls and galleries ring with his outcries. Guards, pages, and attendants rushed in, but Don Juan kept them at bay until the appearance of the king restored order. On inquiring into the cause of the affray he acted with proper discrimination. Don Juan was held sacred as an ambassador, and the renegado was severely punished for having compromised the hospitality of the royal palace.
The tumult in the Alhambra, however, soon caused a more dangerous tumult in the city. It was rumored that Christians had been introduced into the palace with some treasonable design. The populace caught up arms and ascended in throngs to the Gate of Justice, demanding the death of all Christian spies and those who had introduced them. This was no time to reason with an infuriate mob, when the noise of their clamors might bring the garrison of the Albaycin to back them. Nothing was left for El Zagal but to furnish Don Juan with a disguise, a swift horse, and an escort, and to let him out of the Alhambra by a private gate. It was a sore grievance to the stately cavalier to have to submit to these expedients, but there was no alternative. In Moorish disguise he passed through crowds that were clamoring for his head, and, once out of the gate of the city, gave reins to his horse, nor ceased spurring until he found himself safe under the banners of Don Fadrique.
Thus ended the second embassy of Don Juan de Vera, less stately but more perilous than the first. Don Fadrique extolled his prowess, whatever he may have thought of his discretion, and rewarded him with a superb horse, while at the same time he wrote a letter to El Zagal thanking him for the courtesy and protection he had observed to his ambassador. Queen Isabella also was particularly delighted with the piety of Don Juan and his promptness in vindicating the immaculate character of the Blessed Virgin, and, besides conferring on him various honorable distinctions, made him a royal present of three hundred thousand maravedis.*

The report brought by this cavalier of affairs in Granada, together with the preceding skirmishings between the Moorish factions before the walls, convinced Don Fadrique that there was no collusion between the monarchs: on returning to his frontier post, therefore, he sent Boabdil a reinforcement of Christian foot-soldiers and arquebusiers, under Fernan Alvarez de Sotomayor, alcayde of Colomera. This was as a firebrand thrown in to light up anew the flames of war in the city, which remained raging between the Moorish inhabitants for the space of fifty days.
