Yuwen Hu
In summer 567, when the Chen general Hua Jiao (華皎), fearful of adverse intentions of the regent Chen Xu, offered to defect with his Xiang Province (湘州, modern central Hunan), Yuwen Hu, over the opposition by the official Cui You (崔猷), sent an army commanded by Emperor Wu's brother Yuwen Zhi (宇文直) the Duke of Wei to assist Hua and the forces of Northern Zhou's vassal Emperor Ming of Western Liang, who was also aiding Hua. The Chen general Wu Mingche, however, quickly defeated the joint forces of Northern Zhou, Western Liang, and Hua, forcing Hua and Yuwen Zhi to both give up the war and flee to the Western Liang capital Jiangling. Chen was able to retain all of Hua's territory and further make minor territorial gains against both Northern Zhou and Western Liang as well. Yuwen Hu relieved Yuwen Zhi from his posts, and while Yuwen Zhi was eventually restored to them, Yuwen Zhi, who had previously had a cordial relationship with Yuwen Hu, bore a grudge against Yuwen Hu and secretly encouraged Emperor Wu to act against Yuwen Hu.
