慕容恪
In 355, angered that his cousin Duan Kan (段龕), who was in control of modern Shandong and nominally a Jin vassal (as Duke of Qi), wrote a letter to him denouncing him for claiming imperial title, Murong Jun sent Murong Ke and Yang Wu against him. In 356, despite the heavy fortifications that Duan's capital Guanggu (廣固, in modern Qingzhou, Shandong) had, Murong Ke sieged it, and after Duan's food supplies ran out, he was forced to surrender. Murong Jun initially spared Duan, but for reasons unknown, he executed Duan in 357.
