あらすじ
In 1258 A.D., the small city of Bija on the Persian plateau was besieged by a branch of the Mongol army, which had conquered half the world with their powerful cavalry. The Mongols numbered 20,000, while the population of Bija was only 5,000. Their eventual fall was clear for all to see… The story depicts the invasion of Persia by the Mongol Empire, the battle for the small city-state of Bija, and its desperate resistance against the greatest upheaval in history.
