In July 1900, the combined force of the Eight-Nation Alliance descended on Beijing and Tianjin and looted and pillaged the cities. Lin Hei'er and other leaders put up fierce resistance. Lin Hei'er was injured during the Battle of Tientsin and was captured along with the other leaders on July 14, 1900, when the imperial troops who secretly helped the rebels abandoned them to their fate. Her final destination is unknown. Probably she was tried and executed, although turned into a popular heroine, the popular songs proclaimed that she survived.
