to relieve the Legation Quarter siege. Military engagement, punitive expeditions and looting The allied troops invaded and occupied Beijing on 14 August 1900. They defeated the Qing Imperial Army's Wuwei Corps in several engagements and quickly brought an end to the siege and also the Boxer Rebellion. Empress Dowager Cixi, the Emperor and high government officials fled the Imperial Palace for Xi'an and sent Li Hongzhang for peace talks with the Alliance. As Allied troops moved from Beijing into the North China countryside, they executed unknown numbers of people accused or suspected of being or resembling Boxer rebels, which became the subject of an early short film. A US Marine wrote that he witnessed German and Russian troops raping and then bayoneting women. While the Allies were in Beijing, they looted the palaces, yamens, and government buildings inflicting incalculable loss of cultural relics, books on literature and history (including the famous Yongle Dadian) and damage to cultural heritage (including the Forbidden City, the Summer Palace, Xishan and the Old Summer Palace). More than 3,000 gold-plated bronze Buddhas, 1,400 artistic products and 4,300 bronzes in Songzhu Temple (嵩祝寺) were looted. The gold plating on the copper tanks in front of the Forbidden City palaces was scraped off by the Alliance, leaving scratch marks that can be seen even now. The Yongle Dadian that was compiled by 2,100 scholars during the Ming Yongle period (1403–1408), with a total of 22,870 volumes, was partially destroyed in the Second Opium War in 1860. Later, it was collected in the Imperial Palace on Nanchizi Street. It was found and destroyed completely by the Alliance in 1900. Part of the Yongle Dadian was used for the construction of fortifications. The Siku Quanshu was compiled by 360 scholars during the Qing Qianlong period. It collected 3,461 ancient books, totaling 79,309 volumes. The whole book consisted of seven sets. One set was destroyed in 1860 during the Arrow War. Another 10,000 plus volumes were destroyed in 1900 by the Eight-Nation Alliance. The Hanlin Academy houses a collection of precious books, orphans, books of the Song dynasty, literature and history materials, and precious paintings. The Eight-Nation Alliance looted the collections. Some of these looted books remain in the custody of museums in London and Paris.
