Sun Bin
In 354 BC, Wei attacked the State of Zhao, with Pang Juan leading the Wei forces. Zhao requested help from Qi whereupon King Wei of Qi ordered Tian Ji and Sun Bin to lead an army to reinforce Zhao. Sun Bin proposed the strategy of "Besieging Wei to rescue Zhao", and Tian Ji followed the plan, ordering an attack on Wei, forcing Pang Juan to turn back to save Wei, and effectively lifting the siege on Zhao. In 341 BC, Wei attacked the State of Han with Pang Juan commanding the Wei army. Han was an ally of Qi such that Qi responded by sending an army to reinforce Han. Sun Bin was appointed as commander-in-chief of the Qi army this time, with Tian Ji as his deputy. The Qi army scored a major victory in the ensuing Battle of Maling in 342 BC, which culminated in a crushing defeat for Wei and the death of Pang Juan.
