 Yuwen Tai therefore began to prepare attacking Emperor Yuan at his headquarters of Jiangling (江陵, in modern Jingzhou, Hubei), as Emperor Yuan had made Jiangling his capital and declined to move back to the old capital Jiankang.The Western Wei general Ma Bofu (馬伯符), formerly a Liang general, secretly revealed the attack plans to Emperor Yuan, but Emperor Yuan did not believe Ma and took minimal precautions.In winter 554, under Yuwen Tai's orders, Western Wei forces, commanded by Yu Jin (于謹), who was assisted by Yuwen Tai's nephew Yuwen Hu and Yang Zhong, launched a major attack on Liang.
