Another obstacle, often occurring, was the deep torrents that rushed down in fury from the Andes. They were traversed by the hanging bridges of osier, whose frail materials were after a time broken up by the heavy tread of the cavalry, and the holes made in them added materially to the dangers of the passage. On such occasions, the Spaniards contrived to work their way across the rivers on rafts, swimming their horses by the bridle.9All along the route, they found post-houses for the accommodation of the royal couriers, established at regular intervals; and magazines of grain and other commodities, provided in the principal towns for the Indian armies. The Spaniards profited by the prudent forecast of the Peruvian government.
Passing through several hamlets and towns of some note, the principal of which were Guamachucho and Guanuco, Pizarro, after a tedious march, came in sight of the rich valley of Xauxa. The march, though tedious, had been attended with little suffering, except in crossing the bristling crests of the Cordilleras, which occasionally obstructed their path,--a rough setting to the beautiful valleys, that lay scattered like gems along this elevated region. In the mountain passes they found some inconvenience from the cold; since, to move more quickly, they had disencumbered themselves of all superfluous baggage, and were even unprovided with tents.10 The bleak winds of the mountains penetrated the thick harness of the soldiers; but the poor Indians, more scantily clothed and accustomed to a tropical climate, suffered most severely.
