On two of its sides, the rock on which Galera rested descended almost perpendicularly, forming the walls of a ravine fenced in on the opposite quarter by precipitous hills, and thus presenting a sort of natural ditch on a gigantic scale for the protection of the place. The houses rose one above another, on a succession of terraces, so steep that in many instances the roof of one building scarcely reached the foundation of the one above it. The houses which occupied the same terrace, and stood therefore on the same level, might be regarded as so many fortresses. Their walls, which, after the Moorish fashion, were ill-provided with lattices, were pierced with loopholes, that gave the marksmen within the command of the streets on which they fronted; and these streets were still further protected by barricades thrown across them at only fifty paces' distance from each other.[217] Thus the whole place bristled over with fortifications, or rather seemed like one great fortification itself, which nature had combined with art to make impregnable. It was well victualled for a siege, at least with grain, of which there was enough in the magazines for two years' consumption. Water was supplied by the neighbouring river, to which access had been obtained by a subterranean gallery, lately excavated in the rock. These necessaries of life the Moriscoes could command. But they were miserably deficient in what, in their condition, was scarcely less important,--fire-arms and ammunition. They had no artillery except the two falconets before noticed; and they were so poorly provided with muskets as to be mainly dependent on arrows, stones, and other missiles, such as had filled the armories of their ancestors. To these might be added swords, and some other weapons for hand-to-hand combat. Of defensive armour they were almost wholly destitute. But they were animated by an heroic spirit, of more worth than breastplate or helmet, and to a man they were prepared to die rather than surrender.
