I read the Art of War for pleasure
And I like reading about strategic legends like this one
Borrowing of arrows with straw boats
Prior to the Battle of Red Cliffs, Zhuge Liang visited Sun Quan's camp to assist Zhou Yu. Zhou Yu was jealous of Zhuge Liang's talent and felt that Zhuge would become a threat to his lord in future. He assigned Zhuge Liang the task of making 100,000 arrows in ten days or face execution for failure in duties under military law. Zhuge Liang promised that he could complete the mission in three days. With help from Lu Su, Zhuge Liang prepared 20 large boats, each manned by a few soldiers and filled with human-like figures made of straw and hay.
At dawn, when there was a great fog, Zhuge Liang deployed the boats and they sailed towards Cao Cao's camp across the river. He ordered the troops to beat war drums loudly and shout orders to imitate the noise of an attack. Upon hearing the noise, Cao Cao's troops rushed out to engage the enemy, but they were unsure of the enemy's strength, because their vision was obscured by the fog. They fired volleys of arrows towards the sound of the drums and the arrows became stuck in the straw figures. In the meantime, Zhuge Liang was enjoying wine with Lu Su inside the cabin and they returned to camp when the fog cleared. Zhuge Liang acquired more than 100,000 arrows with his plan and Zhou Yu had no choice but to let him off.
