The international force reached Beijing on 14 August. Following the defeat of Beiyang army in the First Sino-Japanese War, the Chinese government had invested heavily in modernizing the imperial army, which was equipped with modern Mauser repeater rifles and Krupp artillery. Three modernized divisions consisting of Manchu Bannermen protected the Beijing Metropolitan region. Two of them were under the command of the anti-Boxer Prince Qing and Ronglu, while the anti-foreign Prince Duan commanded the ten-thousand-strong Hushenying, or "Tiger Spirit Division", which had joined the Gansu Braves and Boxers in attacking the foreigners. It was a Hushenying captain who had assassinated the German diplomat Ketteler. The Tenacious Army under Nie Shicheng received Western style training under German and Russian officers in addition to their modernised weapons and uniforms. They effectively resisted the Alliance at the Battle of Tientsin before retreating and astounded the Alliance forces with the accuracy of their artillery during the siege of the Tianjin concessions (the artillery shells failed to explode upon impact due to corrupt manufacturing). The Gansu Braves under Dong Fuxiang, which some sources described as "ill disciplined", were armed with modern weapons but were not trained according to Western drill and wore traditional Chinese uniforms. They led the defeat of the Alliance at Langfang in the Seymour Expedition and were the most ferocious in besieging the Legations in Beijing. Some Banner forces were given modernised weapons and Western training, becoming the Metropolitan Banner forces, which were decimated in the fighting. Among the Manchu dead was the father of the writer Lao She.
