The 1883 campaigns in Tonkin had been conducted, like most French colonial enterprises, by the
troupes de marine, and had been overseen by the navy ministry. In December 1883, however, in view of the increasing commitment of troops from Algeria to Tonkin, the army ministry insisted on appointing a general from the regular army to command of the Tonkin Expeditionary Corps, which would be henceforth be constituted as a two-brigade infantry division with the normal complement of artillery and other supporting arms.
Jules Ferry's cabinet approved this recommendation, and Courbet was replaced in command of the expeditionary corps on 16December 1883 by General
Charles-Théodore Millot—ironically, on the very day on which he captured Sơn Tây. He resumed command of the Tonkin Coasts naval division, and for the next six months played a most unwelcome subordinate role, hunting down bands of Vietnamese pirates in the Gulf of Tonkin while Millot was winning glory in the
Bắc Ninh campaign. Courbet's luck changed in June 1884. On 27June, in response to the news of the
Bắc Lệ ambush, the Tonkin Coasts naval division and the Far East naval division were amalgamated into a
Far East Squadron. The new squadron, which would remain in existence throughout the Sino-French War, was placed under Courbet's command, with Admiral
Sébastien Lespès (the commander of the Far East naval division) second in command. Courbet's squadron initially included the ironclads
Bayard (the flagship),
Atalante,
La Galissonnière and
Triomphante, the cruisers , , and , the light frigates
Hamelin and
Parseval, the gunboats
Lynx,
Vipère,
Lutin and
Aspic, the troopships
Drac and
Saône and Torpedo Boats Nos. 45 and 46. In July 1884 Courbet was ordered to concentrate part of the squadron at Fuzhou, to threaten the
Fujian fleet (one of China's four regional fleets) and the
Foochow Navy Yard.
Min River operations, August 1884 Negotiations between France and China to resolve the crisis over the
Bắc Lệ ambush broke down in mid- August and on 22August Courbet was ordered to attack the Chinese fleet at Fuzhou. In the
Battle of Fuzhou (also known as the Battle of the Pagoda Anchorage) on 23August 1884, Courbet's
Far East Squadron annihilated China's outclassed Fujian fleet and severely damaged the Foochow Navy Yard. Nine Chinese ships were sunk in less than an hour, including the corvette
Yangwu, the flagship of the Fujian fleet. Chinese losses may have amounted to 3,000 dead, while French losses were minimal. Courbet then successfully withdrew down the
Min River to the open sea, destroying several Chinese shore batteries from behind as he took the French squadron through the Min'an and Jinpai passes.
Operations in Formosa, October 1884 In late September 1884, much to his distaste, Courbet was ordered to use the Far East Squadron to support the landing of a French expeditionary corps at Keelung and Tamsui in northern Formosa (Taiwan). Courbet argued vigorously against a campaign in Formosa and submitted alternative proposals to the navy ministry for a campaign in northern Chinese waters to seize Port Arthur or Weihaiwei. He was supported by
Jules Patenôtre, the French minister to China, but both men were overruled. On 1 October Lieutenant-Colonel Bertaux-Levillain landed at Keelung with a force of 1,800 marine infantry, forcing the Chinese to withdraw to strong defensive positions which had been prepared in the surrounding hills. The French force was too small to advance beyond Keelung. Meanwhile, after an ineffective naval bombardment on 2October, Admiral Lespès attacked the Chinese defences at
Tamsui with 600 sailors from his squadron's landing companies on 8October, and was decisively repulsed by forces under the command of the Fujianese general
Sun Kaihua (孫開華). The French were now committed to a prolonged
Keelung Campaign, and Courbet's squadron was tied down in a largely ineffective blockade of Formosa.
Battle of Shipu Bay, February 1885 After several months of inactivity, Courbet won a series of victories in the spring of 1885. Courbet's squadron had been reinforced substantially since the start of the war, and he now had considerably more ships at his disposal than in October 1884. In early February 1885 part of his squadron left Keelung to head off a threatened attempt by part of the Chinese Southern Seas fleet to break the French blockade of Formosa. On 11February Courbet's task force met the cruisers
Kaiji,
Nanchen and
Nanrui, three of the most modern ships in the Chinese fleet, near Shipu Bay, accompanied by the frigate
Yuyuan and the composite sloop
Chengqing. The Chinese scattered at the French approach, and while the three cruisers successfully made their escape, the French succeeded in trapping
Yuyuan and
Chengqing in Shipu Bay. On the night of 14February, in the
Battle of Shipu, both ships were crippled during a daring French torpedo attack,
Yuyuan by a French spar torpedo and
Chengqing by
Yuyuan's fire. Both ships were subsequently scuttled by the Chinese.
Blockade of Ningbo, March 1885 Courbet followed up this success on 1 March by locating
Kaiji,
Nanchen and
Nanrui, which had taken refuge with four other Chinese warships in Zhenhai Bay, near the port of Ningbo. Courbet considered forcing the Chinese defences, but finally decided to guard the entrance to the bay to keep the enemy vessels bottled up there for the duration of hostilities. A brief and inconclusive skirmish between the French cruiser and the Chinese shore batteries on 1March enabled the Chinese general Ouyang Lijian, charged with the defence of Ningbo, to claim the so-called
Battle of Zhenhai as a defensive victory.
Rice blockade, March–June 1885 In February 1885, under diplomatic pressure from China, Britain invoked the provisions of the 1870 Foreign Enlistment Act and closed Hong Kong and other ports in the Far East to French warships. The French government retaliated by ordering Courbet to implement a 'rice blockade' of the Yangzi River, hoping to bring the Qing court to terms by provoking serious rice shortages in northern China. The rice blockade severely disrupted the transport of rice by sea from Shanghai and forced the Chinese to carry it overland, but the war ended before the blockade seriously affected China's economy.
Pescadores campaign, March 1885 A major French victory at Keelung in early March 1885 enabled Courbet to detach a marine infantry battalion and a marine artillery section from the Keelung garrison to capture the Pescadores Islands in late March. Courbet directed operations in person, and this brief colonial campaign was fought in the traditional style, by ships of the French navy and by the
troupes de marine. Strategically, the
Pescadores Campaign was an important victory, which would have prevented the Chinese from further reinforcing their army in Formosa, but it came too late to affect the outcome of the war. A proposal to use the Far East squadron to make a landing in the
Gulf of Petchili was cancelled on the news of the French defeat in the
Battle of Bang Bo (24March 1885) and the subsequent
retreat from Lạng Sơn, and Courbet was on the point of evacuating Keelung to reinforce the Tonkin expeditionary corps, leaving only a minimum garrison at Makung in the Pescadores, when hostilities came to an end in April 1885. ==Courbet's death and state funeral, June–September 1885==
