竇武
In autumn of that year, the eunuchs discovered the plan and became enraged. Zhu Yu (朱瑀), the first eunuch to discover the plan, formed a conspiracy with 17 eunuchs to strike back at Chen and Dou. They quickly took Emperor Ling into custody (claiming to him—which he believed—for his own protection) and issued edicts executing the military commanders who supported Chen and Dou, and then kidnapped Empress Dowager Dou. They then sent forces to capture Chen and Dou. Chen was quickly captured and executed, while Dou publicly declared that the eunuchs were rebelling and put on a resistance. The eunuchs tricked the general Zhang Huan (張奐) into believing that Dou Wu was in fact committing treason, and Zhang defeated Dou in battle. Dou killed himself after defeat, and the Dou clan was slaughtered, except that his wife was exiled to Bijing (比景, in modern northern Vietnam). Empress Dowager Dou was put under house arrest, although maintaining her title of empress dowager.
