The Manchu General Ronglu concluded that it was futile to fight all of the powers simultaneously, and declined to press home the siege. The Manchu Zaiyi (Prince Duan), an anti-foreign friend of Dong Fuxiang, wanted artillery for Dong's troops to destroy the legations. Ronglu blocked the transfer of artillery to Zaiyi and Dong, preventing them from attacking. Ronglu forced Dong Fuxiang and his troops to pull back from completing the siege and destroying the legations, thereby saving the foreigners and making diplomatic concessions. Ronglu and Prince Qing sent food to the legations, and used their Manchu Bannermen to attack the Muslim Gansu Braves ("Kansu Braves" in the spelling of the time) of Dong Fuxiang and the Boxers who were besieging the foreigners. They issued edicts ordering the foreigners to be protected, but the Gansu warriors ignored it, and fought against Bannermen who tried to force them away from the legations. The Boxers also took commands from Dong Fuxiang. Ronglu also deliberately hid an Imperial Decree from General Nie Shicheng. The Decree ordered him to stop fighting the Boxers because of the foreign invasion, and also because the population was suffering. Due to Ronglu's actions, General Nie continued to fight the Boxers and killed many of them even as the foreign troops were making their way into China. Ronglu also ordered Nie to protect foreigners and save the railway from the Boxers. Because parts of the Railway were saved under Ronglu's orders, the foreign invasion army was able to transport itself into China quickly. General Nie committed thousands of troops against the Boxers instead of against the foreigners. Nie was already outnumbered by the Allies by 4,000 men. General Nie was blamed for attacking the Boxers, as Ronglu let Nie take all the blame. At the Battle of Tianjin (Tientsin), General Nie decided to sacrifice his life by walking into the range of Allied guns.
