Story:
During the Western Han Dynasty, Li Ling led 5,000 infantrymen to attack the Xiongnu, defeating 30,000 Xiongnu soldiers. The Chanyu (leader of the Xiongnu) had no choice but to order a retreat.
Soon after, he assembled 80,000 cavalrymen to attack the Han army, completely encircling them.
Li Ling raised his arm and called out, and the Han soldiers, regardless of their injuries or sickness, bravely fought the enemy. However, outnumbered, after two days of fierce fighting, Li Ling's army was defeated, and he was captured.
