Historical Bio—Sun Lang (Zaoan)

Historic (Confirmed)

Sun Lang, styled Zhaoan, was son of Sun Jian and a concubine. Sun Lang was young when Sun Jian and Sun Ce passed away, and under Sun Quan did not serve in the military for some time, instead working as a palace guard in Wu commandery.

In AD 222 Wei invaded Wu on multiple fronts. One of which was commanded by Cao Xiu who attacked Dongkou with his fleet. Lü Fan, Grand Administrator of Danyang at the time, prepared his own navy to oppose him. Weather was not suitable for a fire attack, so he ordered that none be conducted. Sun Lang, one of his subordinates, disobeyed this order, and as a result much of Lü Fan’s fleet was destroyed, though the battle was salvaged. Outraged over this action Sun Quan imprisoned Sun Lang for life and denied him familial relations. He even changed his surname to Ding (丁), a great disgrace. (1)
