The Battle of Fuzhou, or Battle of Foochow, also known as the Battle of the Pagoda Anchorage (French: Combat naval de Fou-Tchéou, Chinese: , 馬江之役 or 馬尾海戰, literally Battle of Mawei), was the opening engagement of the 16-month Sino-French War (December 1883 – April 1885). The battle was fought on 23 August 1884 off the Pagoda Anchorage in Mawei () harbour, to the southeast of the city of Fuzhou (Foochow). During the battle Admiral Amédée Courbet's Far East Squadron virtually destroyed the Fujian Fleet, one of China's four regional fleets. Background On 11 May 1884 French and Chinese negotiators concluded the Tientsin Accord, an agreement designed to end several months of undeclared hostilities between France and China in Tonkin. On 23 June 1884, French troops advancing to occupy Lạng Sơn, in accordance with the terms of this agreement, clashed near the small town of Bắc Lệ with a detachment of the Chinese Guangxi Army. The Chinese opened fire on the advancing French, precipitating a two-day battle in which the French column was seriously mauled. This incident, the Bắc Lệ ambush, was the proximate cause of the Sino-French War. When news of the Bắc Lệ ambush reached Paris, there was fury at what was perceived as blatant Chinese treachery. Jules Ferry's government demanded an apology, an indemnity, and the immediate implementation of the terms of the Tianjin Accord. The Chinese government agreed to negotiate, but refused to apologise or pay an indemnity. The mood in France was against compromise, and although negotiations continued throughout July, Admiral Courbet was ordered to take his squadron to Fuzhou (Foochow). Courbet was instructed to prepare to destroy the Foochow Navy Yard, downriver from Fuzhou at Mawei, and to attack the Chinese fleet in Mawei harbour. Ironically, the Foochow Navy Yard represented a substantial French investment in China's future, having been built several years earlier under the direction of the French administrator Prosper Giquel. During the second half of July and the first half of August Courbet gradually concentrated his squadron in Mawei harbour, at the Pagoda Anchorage—named for a conspicuous Chinese pagoda, the Luoxingta (), which stood on a hill above the harbour. Negotiations between France and China broke down in mid-August, and on the evening of 22 August Courbet was authorised by the French government to commence hostilities. He duly notified the foreign consuls, the governor-general of Fujian and Zhejiang, and the commanders of
