From Baidu (https://baike.baidu.com/item/连环计/5842#ref__5340118):
“Bi Zaiyu Uses Chain Stratagems”
“The Song Dynasty general Bi Zaiyu once used a Chain Stratagem to fight a flawless battle. He realized that the Jins were fierce, especially mounted troops, and that fighting them head-on would result in great injury or death.”
“So he advocated for seizing the enemy’s biggest weakness, attempted to clamp down on the enemy, and looked for the best opportunity to fight.”
“Once, in an counter with Jin troops, he commanded that none of his divisons could fight the enemy head-on, instead adopting guerrilla and mobile tactics. Once the enemy advanced, he ordered his ranks to retreat, waited for the enemy to settle, then ordered an attack. Once the Jin troops attempted to repel the attack, he once again ordered his troops to disappear without a trace. In this manner, retreating and advancing, fighting and stopping, were the Jin troops worn down. The Jins could not fight even if they wanted to, and could not move freely.”
“Late in the night, the Jin army was completely worn out, and was preparing to return to camp for rest. Bi Zaiyu prepared numerous black beans boiled with fragrance, and secretly spread them all over the battlefield. Then, he called a surprise attack on the Jin army. Having no alternative, the Jin army could only do their best to fight back. Bi Zaiyu’s troops fought the Jin army for a short time, then retreated.”
“The Jin army was furious, and chased them on the back of a victory. Who knew—the Jin army’s horses, hungry and thirsty after a day of running back and forth continuously, smelled fragrance coming from the ground and knew that it could fill their stomachs. The war horses single-mindedly ate them, and even if you whipped them, they wouldn’t move forward a step. The Jin army was unable to control the horses, and in the black night, out of ideas, they appeared completely chaotic.”
“At this time, Bi Zaiyu assembled his army, surrounded the Jin, fought and dealt a crushing defeat, leaving corpses strewn across the open land.”
Baidu cites a source for this information, which is a book on “The 36 Stratagems.” Bi Zaiyu was a real general, but I have no way to verify whether this tale is true or not.
