General Geng Gong of the Eastern Han Dynasty was trapped by the Xiongnu in Shule, an isolated city in the Western Regions. In the end, only 26 men were left. After years of bloody battles, he still refused to surrender.
He had previously sent a soldier, Fan Qiang, to ask for help. Fan Qiang had been begging for a year and finally waited for reinforcements from the court. However, because it had been a long time and the journey was long, the reinforcement generals believed that there was little hope that Geng Gong's men would survive, so they did not intend to sacrifice in vain and were prepared to give up the rescue.
Fan Qiang was unwilling to abandon his comrades and fought tooth and nail. He insisted on leading a team of troops for a long-distance rescue, and finally rescued the 26 people at the cost of hundreds of casualties. When he returned to Yumen Pass all the way, only 13 of the 26 people rescued were alive. This is the famous 13 heroes Geng Gong.
