The Pescadores campaign which took place in late March, 1885, was one of the last campaigns of the Sino-French War (August 1884–April 1885). It was fought to capture the Pescadores, a strategically important archipelago off the western coast of Formosa (Taiwan). Admiral Amédée Courbet, with part of the French Far East Squadron, bombarded the Chinese coastal defences around the principal town of Makung on Penghu Island and landed a battalion of marine infantry which routed the Chinese defenders and occupied Makung.Duboc, 295–303; Garnot, 179–95; Huard, 723–31; Loir, 291–317

The Pescadores were occupied by the French until July 1885 and Admiral Courbet, by then a national hero in France, died aboard his flagship Bayard in Makung harbour during the occupation.

Background The Pescadores Islands, also known from their Chinese name as P'eng-hu (澎湖), were an important transit stop for reinforcements to the Chinese army under the command of Liu Mingchuan confronting the French in northern Taiwan around Keelung, and their capture would prevent further reinforcements from reaching Taiwan. Courbet had wanted to mount an expedition to capture the Pescadores for several months, but the feasibility of the operation depended on the progress of the Keelung Campaign. Colonel Jacques Duchesne's defeat of Liu Mingchuan's forces and capture of the key Chinese position of La Table on 7 March 1885 finally disengaged Keelung, allowing the French to detach troops from its garrison for a descent on the Pescadores.Garnot, 177–8

French and Chinese forces Courbet's flotilla consisted of the ironclads and , the cruisers and , the gunboat Vipère and the troopship Annamite. His landing force consisted of an understrength battalion of marine infantry (400 men as opposed to the usual complement of 600 men) under the command of chef de bataillon Lange and a marine artillery section of two mountain guns (Lieutenant Lubert).Garnot, 178–9Lange's battalion consisted of the 25th, 26th, 27th and 30th Companies, 2nd Marine Infantry Regiment (Captains Logos, Harlay, Cramoisy and Vaillance).

The Chinese garrison of the Pescadores, which had been substantially reinforced at the beginning of 1885, was commanded by the generals and Zheng Yingjie (鄭膺杰), and numbered around 2,400 men.Duboc, 300; Lung Chang, 329 A number of foreign officers served with the Chinese garrison, including an American officer named Nelson, responsible for the defence of one of the Makung forts, whose diary of events was later recovered by the French. Initially optimistic, by March 1885 Nelson had despaired of training up the Chinese gunners to the standard necessary to meet the French in battle.

The fortifications of the Pescadores were designed primarily to protect Makung and deny entrance to Makung Bay, and also if possible to cover the southern entrance to P'eng-hu Bay, which would have to be traversed first by an attacking squadron. The most formidable obstacles were the two Makung forts, placed on either side of the entrance to Makung Bay. The Northern Fort, just to the southwest of Makung, deployed three Armstrong cannons, and was flanked by a number of subsidiary positions in which the Chinese had deployed a dozen rifled French Voruz cannon of various calibres. The Southern Fort, or Dutch Fort (it had been built by the Dutch in the seventeenth century), was armed with two and two smoothbore cannon. A third battery, sited on Observatory Island just inside Makung Bay, also covered the entrance to the bay, which had also been blocked by a barrier of chains. The Observatory Island battery was armed with two Armstrong cannon and a Chinese cannon. The Chinese had also built a battery armed with smoothbore cannon to sweep the plain to the east of Makung and a large entrenched camp to the north of the town to house the regular troops of the island's garrison.Garnot, 180–81; Loir, 295

The outer Chinese defences were much weaker. The southern entrance to P'eng-hu Bay was covered on the west by the Hsiaochi battery on Fisher Island (modern Xiyu), and on the east by a battery on Plate Island. The Hsiaochi battery was replaced in the late 1880s by the Hsi Tai battery, whose ruins can still be seen today. The Plate Island battery was quite close to the Southern Fort, and could also cover the approach to Makung Bay. Unfortunately for the Chinese, both these batteries were armed only with a mixture of antiquated smoothbore pieces that offered little threat to the French squadron.Garnot, 181; Loir, 296

The campaign

The French flotilla concentrated off Taiwanfu (modern Tainan) on 28 March, and approached the Pescadores from the west before dawn on 29 March. During the morning of 29 March the French warships bombarded and silenced the Hsiaochi battery and other Chinese shore batteries guarding the approaches to Makung.Garnot, 185–6; Loir, 298–302

In the late afternoon Lange's battalion was put ashore on the southern cape of P'eng-hu Island, at Dome Hill, where it set up a defensive position for the night. There were no Chinese in sight, and the landing was made without resistance.Garnot, 186; Loir, 302

During the night of 29 March the French sent boats to scout a barrage of chains thrown across the entrance to Makung harbour. The scouting party discovered that no mines had yet been attached to the chains, and at dawn on 30 March a party of sailors from Bayard went forward in launches to cut a gap in the barrage. Chinese riflemen tried to disrupt this operation, and one French sailor was killed.Garnot, 186–9; Loir, 302–3

With the barrage breached, Courbet's flotilla entered Makung Bay during the morning of 30 March and bombarded the defences of Makung. At the same time, Lange's battalion left its bivouac on Dome Hill and began to advance towards Makung, its flanks covered by d'Estaing and Vipère in Makung Bay and Annamite in Dome Bay. The column was guided towards its objective by an elderly local fisherman, who had volunteered his services for pay. During the afternoon Lange's men cleared a force of Chinese infantry from the village of Kisambo and closed up to the village of Siu-kuei-kang (modern Suogang, 鎖港), which was strongly held by the Chinese. Lange's men bivouacked for the night to the west of the village, ready to attack the Chinese the following morning. During the evening the French column was reinforced by the landing companies of Bayard, Triomphante and d'Estaing and by four cannon.Garnot, 189–91; Loir, 303–4

On the morning of 31 March Lange attacked the main Chinese defensive line around Siu-kuei-kang. Although the marine infantry and sailors were heavily outnumbered, French naval gunfire tipped the balance in their favour. The Chinese were driven back from their positions and attempted to make a second stand before Makung, near the village of Amo. Lange attacked them again, with equal success, and occupied Makung late in the afternoon.Garnot, 191–3; Loir, 305–6

Most of the defeated Chinese soldiers escaped to Amoy (Xiamen) in mainland China or to Taiwanfu on junks and fishing boats under cover of darkness, though a number of soldiers were caught and handed over to the victorious French by the inhabitants of the Pescadores, who saw no reason to distinguish between two equally unwelcome sets of intruders.Loir, 315

French casualties in the Pescadores campaign were 5 killed and 12 wounded. The wounded included one officer, lieutenant de vaisseau Poirot of Triomphante. Chinese casualties may have amounted to 300 dead and around 400 wounded, and included several senior officers.Garnot, 193; Loir, 306 The French were told by islanders that the American artillery officer Nelson was beheaded during the bombardment of 29 March on the orders of an enraged Chinese commander, because his guns were unable to make any effective reply to the French warships.Duboc, 300

The French bombardment of the Chinese positions on the Pescadores was heard in Taiwanfu on the Formosan mainland. The British missionary William Campbell described the impact of the battle on the town's inhabitants:

One quiet afternoon during the spring of 1885 the people of Formosa were startled on hearing what seemed to them the sound of distant thunder. It was not thunder, but the ponderous ironclads of France engaged in demolishing the fortifications over against Fisher Island and Makung. Those fortifications were mounted with good-sized guns of foreign make, and occupied by several thousands of soldiers who had been hastily called from various centres on the mainland. It all availed nothing. Fighting was to be conducted in a very different style from that of other days; and, sure enough, the large floating batteries of the French fleet loomed into sight. According to popular report, no time was lost with any kind of preliminary formalities. The Chinese commenced to fire on the advancing ships, which continued steadily and with ominous silence to press forward in the direction of Makung. When within about rifle-shot range, there burst from them such a tremendous discharge against the large fort outside of the town that many a heart must have been filled with terror and amazement. Indeed, some say that on witnessing the fearful havoc caused by this opening volley from the French guns, both officers and men began to scamper off from the entrenchments; a statement which, however, cannot be altogether correct, since the number of soldiers suffering from frontal wounds, who afterwards found their way to the mission hospital at [Taiwanfu] showed conclusively that not a few of those poor matter-of-fact Chinamen must have made a noble stand against the invaders of their country.Campbell, 172–3

The Pescadores campaign was Courbet's last military victory. Although it was a minor operation compared with the capture of Sơn Tây or the Battle of Fuzhou, in the eyes of his officers it was his most flawless military achievement. Significantly, Courbet directed operations in person, and chose to fight this brief colonial campaign in the traditional style, with ships of the French navy supporting the land operations of marine infantry and artillery. The decision reflected inter-service rivalries. Courbet was cocking a snook at the army ministry, which had long ago wrested the direction of the Tonkin campaign away from the navy ministry. His timing was perfect. While the army ministry was struggling to explain away General François de Négrier's defeat in the battle of Bang Bo (24 March 1885) and the subsequent French retreat from Lạng Sơn, Courbet presented the navy ministry with an elegant, almost bloodless victory in the Pescadores. The Sino-French War ended on a high note for the French navy and the Troupes de Marine.

On 27 July 1885, in the wake of an enquiry into their conduct, the defeated Chinese generals Zhou Shanchu and Zheng Yingjie were demoted and punished for the loss of the Pescadores by being posted to the remote northern Chinese province of Heilongjiang.Lung Chang, 329

Significance of the campaign The news of the French capture of the Pescadores initially caused little stir in Paris, as the headlines in early April 1885 were monopolised by the so-called 'Tonkin affair' (the collapse of Jules Ferry's government on 30 March 1885 in the wake of the retreat from Lạng Sơn).
