Yang Hu
In 279, Wang Jun thought that it was time to launch the decisive attack on Wu. However, the majority of officials in the imperial court strongly objected to launching an invasion, except Du Yu and Zhang Hua, who strongly supported Wang Jun's idea. The two of them managed to convince Emperor Wu to agree with them, and the strategy of Jin was basically the one planned by Yang Hu when he was still alive. 200,000 troops out of the 500,000 strong regular army were deployed for the campaign, and by this time, the Jin navy was also at least on par with the Eastern Wu navy.
