張紘
Lun sent Sun Fu and Zhang Hong with 24,000 men to secure the passes and 30,000 under Sun Hui to confront Ying. Zhang Hong confronted Jiong and defeated him several times before Jiong retreated and made camp at Yingyin, midway between Yangdi and Xuchang. Sun Fu panicked and fled back to Luoyang, spreading rumors that Zhang Hong had been defeated. Lun ordered the main army to return and protect Luoyang and then to confront Ying again. However by this time Jiong had reversed his early defeats and forced Zhang Hong back toward the capital. Sun Hui led the main army against Ying at Yellow Bridge, defeating the prince and killing 10,000. Ying rallied his troops and returned with a counterattack, smashing Hui's forces at the Chou River north of the Yellow River.
