Erzhu Zhao
Soon, the Erzhu forces, under Erzhu Zhao's command, advanced south and caught Emperor Xiaozhuang, who did not expect Erzhu Zhao to be able to cross the Yellow River easily, by surprise when he had his army ride on horsebacks across the river around the new year 531. Emperor Xiaozhuang's imperial guards collapsed, and he was captured by Erzhu Zhao's cavalry soldiers and imprisoned, less than three months after he killed Erzhu Rong. Erzhu Zhao killed Emperor Xiaozhuang's infant son (by Empress Erzhu), while allowing his soldiers to pillage Luoyang, killing many officials and raping many honored women.
