Huang Zu hid his archers on the river bank; when they saw the boats approaching the shore, they let loose with a wild flurry of arrows. Jian ordered his troops to take no rash actions, but rather to hide in the hold of the boats. The boats were to advance and withdraw in order to bait the enemy into firing. Over the course of three days, they approached the shore dozens of times. Huang Zu's army thought of nothing else but shooting their arrows; eventually, they exhausted their supply. Jian ordered his men to fish the hundreds of thousands of arrows out of the water. The winds were favorable on that day; Jian ordered his troops to shoot the arrows in unison. The forces on shore could not hold their ground, and had no choice but to withdraw.
