Wei Qing
During the Battle of Mobei in 119 BC, an old but still enthusiastic Li Guang insisted Emperor Wu to promise him a vanguard position, but the emperor had secretly messaged generalissimo Wei Qing to "not" let Li lead the vanguard due to his infamy of "bad fortune". Wei Qing then assigned Li Guang to combine forces with Zhao Shiqi (赵食其/趙食其) on an eastern flanking route through a barren plain. Li Guang protested against the arrangement and angrily stormed out of the main camp. However, he and Zhao then got lost and missed the battle entirely, and only rejoining the main force after Wei Qing returned from a hard-fought victory against Yizhixie Chanyu's numerically superior army. As a result, Li and Zhao were summoned to a court martial to explain why they failed to accomplish orders and put the battle strategy at risk. Li Guang, frustrated and humiliated as this was his last chance to obtain sufficient s to receive a marquessate as a reward, committed honor suicide. His son Li Gan blamed Wei Qing for his father's death, assaulted Wei and was later shot dead for the offence by his own superior Huo Qubing (who was Wei's nephew) during a hunting trip.
