The next day, Saint Patrick's day precisely, the seventeenth of March, they went to another small town named Silenen. From that they advanced through the Alps. Now the mountains were laden and filled with snow and ice, and the roads and paths were narrow and rugged. They reached a high bridge in a very deep glen called the Devil's Bridge. One of Ó Néill's horses, which was carrying some of his money, about one hundred and twenty pounds, fell down the face of the high, frozen, snowy cliff which was in front of the bridge. Great labour was experienced in bringing up the horse alone, but the money decided to remain blocking the violent, deep, destructive torrent which flows under the bridge through the middle of the glen. They stayed that night in a little town named Piedimonte. Their journey that day was six leagues.
