This is the remarkable account of the two-year journey across China, Mongolia and Tibet by two French Christian missionaries. After their expulsion from Tibet, where they stayed in the capital Lhasa, they moved back to China. The journey by Évariste Régis Huc and Joseph Gabet, began in September, 1844. They received a commission to travel to Mongolia to check on the progress of the newly established Christian mission created by the Pope. Volume I tells about their adventures in China and Mongolia and Volume II casts light on their further adventures in Tibet.
