冉閔
In 352, Ran Min marched north, ready to engage Former Yan forces. Former Yan soldiers were apprehensive of Ran Min's reputation for being a fierce warrior, but Murong Ke devised a plan to trap Ran, whose forces were largely infantry and had been based in forests. Murong Ke pretended to repeatedly lose engagements, and Ran Wei forces were drawn into the plains. Murong Ke then put his cavalry into square formations, with horses locked in formations with chains, and the Ran Wei infantry could not stand the pressure and collapsed. Ran Min was still battling when his horse suddenly died, and he fell and was captured. Murong Jun executed him and then marched on to the Ran Wei capital Yecheng (鄴城), where Ran Min's wife Empress Dong, his crown prince Ran Zhi, and high level officials continued to try to fend off Former Yan for a while, but late in 352, Yecheng fell, and most of Ran Wei's territory fell to Former Yan. When Murong Jun then claimed imperial title, he created Murong Ke the Prince of Taiyuan in 353.
