Operations of Los Velez--Conspiracy against Aben-Humeya--His Assassination--Election of Aben-Aboo--Vigorous Prosecution of the War--Fierce Combats in the Vega--Impetuous Spirit of Don John--Surprise of Guejar. 1569. While the events related in the preceding chapter were occurring, the marquis of Los Velez lay, with a considerable force, at Adra, a port on the Mediterranean, at the foot of the Alpujarras, which he had selected chiefly from the facilities it would afford him for getting supplies for his army. In this he was disappointed. Before the month of June had expired, his troops had begun to be straitened for provisions. The evil went on increasing from day to day. His levies, composed chiefly of raw recruits from Andalusia, were full of that independent, and indeed turbulent spirit, which belongs to an ill-disciplined militia. There was no lack of courage in the soldiery. But the same men who had fearlessly braved the dangers of the campaign, now growing impatient under the pinch of hunger, abandoned their colours in great numbers. There were various causes for the deficiency of supplies. The principal one of these may probably be found in the remissness of the council of war, several of whose members regarded the marquis with an evil eye, and were not sorry to see his embarrassments. [Sidenote: OPERATIONS OF LOS VELEZ.] Some vigorous measures were instantly to be taken, or the army, it was evident, would soon altogether melt away. By the king's command, orders were despatched to Requesens, who lay with his squadron off the port of Velez-Malaga, to supply the camp with provisions, while it received reinforcements, as before, principally from the Andalusian militia. The army received a still more important accession in the well-disciplined veterans who had followed the grand-commander from Italy. Thus strengthened, and provisioned for a week or more, Los Velez, at the head of twelve thousand men, set forth on the twenty-sixth of July, and struck at once into the Alpujarras. He had been directed by the council to establish himself at Ugibar, which, by its central position, would enable him to watch the movements of Aben-Humeya, and act on any point as occasion required. The marquis, without difficulty, defeated a force of some five or six thousand men, who had been stationed to oppose his entrance into the mountain country. He then pressed forward, and on the high lands beyond Ugibar--which place he had already occupied--he came in sight of Aben-Humeya, with the flower of his troops drawn up to receive him.
