Sun Hao
In comparison to the active preparation of its adversary, the Wu emperor Sun Hao did nearly nothing to defend against an invasion. Some leftover wooden pieces from Wang Jun's naval construction project flowed downstream and were picked up by the Eastern Wu general Wu Yan (吾彥). Wu Yan sent the wooden pieces to Sun Hao as evidence of the imminent attack and asked for reinforcements, but Sun Hao ignored the request as he did to similar suggestions from Lu Kang and others.
