三國志
The 172 campaign, the battle of Jwa-Won, was not recorded in the "Book of the Later Han" or the "Records of the Three Kingdoms", while the 169 campaign was documented. The battle of Jwa-Won only appears in Samguk Sagi. The "Records of the Three Kingdoms" only state that sometime around 175 AD, King Sindae asked to be governed by Xuantu Commandery.
