Valdez was the commander of Eight-Nation Alliance who nominally attacked the Boxer Rebellion. At that time, the Boxer was called the Boxer. At first, the Boxer Rebellion attacked the British and American colonists with the slogan of helping the Qing Dynasty destroy the foreign countries, which was supported by Cixi. Cixi hoped to attack the western colonists with the help of the Boxer Rebellion. However, when Eight-Nation Alliance attacked Peiping, Cixi asked the court to encircle the Boxer when she fled to the north, and then the court pursued the Boxer with Eight-Nation Alliance. Therefore, the real power of China's army has actually been mastered by him, so Wadesi dares to say that he is "the champion commander of the Boxing Party in China".
