Genghis: Lords of the Bow
book
Genghis unites Mongol tribes to cross the Gobi Desert and fight the Chin - gleaming cities, soaring walls, and canals. Laying siege to one fortress after another, Genghis cunningly crushes each enemy differently, overcoming moats, barriers, deceptions, and superior firepower--until his army calls the Emperor in Yenking to kneel.
