In 203, Sun Quan led his forces to attack Huang Zu and defeated him at the Battle of Xiakou. Gan Ning, a skilled archer, led a detachment of troops as backup and came to Huang Zu's rescue. He fired an arrow which killed Ling Cao, a colonel under Sun Quan, thus saving Huang Zu's life. Huang Zu did not change his attitude towards Gan Ning after the incident. Su Fei (蘇飛), an area commander under Huang Zu, recommended Gan Ning as a talent but Huang Zu ignored him. Huang Zu even attempted to induce Gan Ning's followers to abandon their leader and join him instead; some of them agreed.
