What is the allusion of losing your wife and losing your troops?

Allusion: During the Three Kingdoms struggle for hegemony at the end of the Eastern Han Dynasty, Sun Quan wanted to take back Jingzhou, and Zhou Yu came up with a plan to "pretend to recruit relatives and take hostages." Zhuge Liang saw through it and arranged for Zhao Yun to accompany him. He first visited Zhou Yu's father-in-law, Duke Qiao. Duke Qiao persuaded Wu Guotai to meet at Ganlu Temple, and Wu Guotai actually married Sun Shangxiang to Liu Bei. Sun Quan and Zhou Yu were ridiculed as "Zhou Lang's brilliant plan to bring peace to the world, but he lost both his wife and his troops."
