Don Quixote mounted without replying, and, Sancho leading the way on his ass, they entered the side of the Sierra Morena, which was close by, as it was Sancho’s design to cross it entirely and come out again at El Viso or Almodovar del Campo, and hide for some days among its crags so as to escape the search of the Brotherhood should they come to look for them. He was encouraged in this by perceiving that the stock of provisions carried by the ass had come safe out of the fray with the galley slaves, a circumstance that he regarded as a miracle, seeing how they pillaged and ransacked.
That night they reached the very heart of the Sierra Morena, where it seemed prudent to Sancho to pass the night and even some days, at least as many as the stores he carried might last, and so they encamped between two rocks and among some cork trees.(Trans John Ormsby, 1829-1895) Don Quijote library.
