Emperor Wu of Liang
The only real military success that Northern Wei had during this time happened in late 525, when it was able to recapture Pengcheng from Liang—and the success was fortuitous, as the Liang prince Xiao Zong (蕭綜), the son of Emperor Wu of Liang and his concubine Consort Wu, who was previously the concubine of Southern Qi emperor Xiao Baojuan, became convinced that he was actually Xiao Baojuan's posthumous son, and surrendered to Northern Wei, causing his own army to collapse and allowing Northern Wei to reenter Pengcheng.
