In 1925 Aime Tschiffely, a Swiss teacher living in Argentina, set out on his epic ride with two Criollo horses, Mancha and Gato. The amateur explorer's goal was to travel 10,000 miles from Buenos Aires to Washington DC over some of the world's most inhospitable country. Their odyssey lasted two and a half years, forced horses and rider to survive near-impossible conditions, and ended with a hero's welcome at the White House.
