The Braves, who wore traditional uniforms but were armed with modern rifles and artillery, played an important role in 1900 during the Boxer Rebellion. After helping to repel the Seymour Expedition, a multinational foreign force sent from Tianjin to relieve the Beijing Legation Quarter in early June, the Muslim troops were the fiercest attackers during the siege of the legations from 20 June to 14 August. They suffered heavy casualties at the Battle of Peking, in which the Eight-Nation Alliance relieved the siege. The Kansu Braves then guarded the Imperial Court on their journey to Xi'an.
