John Patterson, The Adventures of Captain John Patterson
“ Our road, though passable, extended over a deserted region, planted thinly with chestnut and olive trees, with pines at intervals. Portalegre is large, populous and well built: although not regularly fortified, it is capable, from the strong ground in its neighbourhood, with the aid of some works on the adjacent heights, of making much resistance, and might be rendered formidable to an enemy by some degree of skill combined with labour, and by exertions that the Portuguese will never make. ”
