Instructed by this traitor, the Arab commander caused ten thousand foot soldiers and four thousand horsemen, commanded by a valiant captain, named Ibrahim Albuxarra, to be conveyed by sea to the little port of Adra, at the Mediterranean foot of the mountains. Here they landed, and, guided by the traitor, penetrated to the heart of the sierra, laying every thing waste. The brave mountaineers, thus hemmed in between two armies, destitute of fortresses and without hope of succour, were obliged to capitulate; but their valour was not without avail, for never, even in Spain, did vanquished people surrender on prouder or more honourable terms. We have named the wretch who betrayed his native mountains: let us equally record the name of him whose pious patriotism saved them from desolation. It was the reverend Bishop Centerio. While the warriors rested on their arms in grim and menacing tranquillity among the cliffs, this venerable prelate descended to the Arab tents in the valley, to conduct the capitulation. In stipulating for the safety of his people, he did not forget that they were brave men, and that they still had weapons in their hands. He obtained conditions accordingly. It was agreed that they should be permitted to retain their houses, lands, and personal effects; that they should be unmolested in their religion, and their temples and priests respected; and that they should pay no other tribute than such as they had been accustomed to render to their kings. Should they prefer to leave the country and remove to any part of Christendom, they were to be allowed to sell their possessions; and to take with them the money, and all their other effects.[35] Ibrahim Albuxarra remained in command of the territory, and the whole sierra, or chain of mountains, took his name, which has since been slightly corrupted into that of the Alpuxarras. The subjugation of this rugged region, however, was for a long time incomplete; many of the Christians maintained a wild and hostile independence, living in green glens and scanty valleys among the heights; and the sierra of the Alpuxarras has, in all ages, been one of the most difficult parts of Andalusia to be subdued.
