The Capitulation of Diksmuide, or Dixmuide, then in the Spanish Netherlands, took place from 26 to 28 July 1695, during the 1689 to 1697 Nine Years' War. An Allied garrison of around 4,000 men surrendered to a superior French force.

After six years of war, both sides were financially exhausted; the focus of the 1695 campaign was the Allied siege of Namur, captured by the French in 1692. By attacking garrisons like Diksmuide, the French commander sought to prevent the Allies resupplying their army outside Namur.

Its capitulation after only two days resulted in the court martial of garrison commander Major General Ellenberg, and other senior officers. While the reason for his surrender is still disputed, Ellenberg was executed and several officers dismissed.

Namur surrendered to the Allies in September; although fighting did not formally end until 1697, this was the last major event of the war. The French withdrew from Diksmuide following the Treaty of Ryswick.

Background

Under William's leadership, the Alliance held together through four years of war, with losses that were damaging, but not critical. By 1694, they held a numerical advantage in Flanders, and had recaptured towns like Huy and Diksmuide. However, both sides were also struggling with the huge economic and social costs of the war.^[1]

The 1690s marked the lowest point of the so-called Little Ice Age, a period of cold and wet weather affecting Europe in the second half of the 17th century. Famine in France and Italy was mirrored elsewhere, including Spain and Scotland, where the harvest failed in 1695, 1696, 1698 and 1699 and an estimated 5-15% of the population starved to death.^[2]

The 1695 Flanders campaign; key locations

Most campaigns in this theatre took place in the Spanish Netherlands, a compact area 160 kilometres wide, its highest point only 100 metres above sea level, dominated by canals and rivers, the primary means of transport until the advent of railways in the 19th century. Namur's position at the intersection of the Sambre and Meuse rivers made it vital for defending the Netherlands against French invasion, and its recapture the main Allied objective for 1695.^[3]

In April 1695, Louis ordered Boufflers to build entrenchments between the Scheldt and Lys, from Coutrai or Kortrijk to Avelgem.^[4] William marched on these in June, with the bulk of the Allied forces, but secretly detached Frederick of Prussia to Namur. Once Frederick was in place on 2 July, William joined him; the Allies were now split into a besieging force of 58,000 at Namur and a field army of 102,000 under Prince Vaudémont to cover Villeroi.^[5]

To support Vaudémont and secure supply lines for the besiegers, it was vital to hold as many crossing points as possible. One of the most important was Diksmuide, positioned on the Lys; while little more than a large village, even nearby Deinze controlled a bridge across the Lys, making it of far greater strategic significance than its size indicates.^[6]

Siege

Vaudémont's task was to keep his army between Villeroy and Namur; Villeroy tried to tempt him out of position by attacking Allied-held towns like Knokke and Beselare, now Zonnebeke, but he refused to be drawn. It was accepted even places like Namur would fall given enough time, so the garrisons in Diksmuide and Deinze were expected to delay Villeroy for as long as possible.^[7]

Diksmuide sits on the Yser River, which begins in France, then runs through the town before entering the North Sea at Nieuwpoort. French defences followed the Yser via Ypres and Comines to Espierres and hardly changed between 1689-1694; its enduring strategic significance led to this line being fought over in both 1914 and 1940, while Diksmuide itself was attacked by the Germans in October 1914.^[8]

The garrison commander at Diksmuide was Major-General Ellenberg, an experienced Dane who served William in Ireland and elsewhere. The town was taken by the Allies in 1694, and although the defences were in a poor state, it was held by a strong garrison of eight battalions of infantry plus several squadrons from Lloyd's Dragoons.^[9]

Vaudémont's covering army had been reduced by the need to bolster the assault forces at Namur; by stripping garrisons from Ypres and Menin, Villeroi achieved local superiority of 90,000 to 37,000. However, an attack on 14 July failed to break the Allied line; Vaudémont was able to conduct an orderly retreat, using the bridge across the Lys at Deinze.^[10]

Shortly after this, a force under the Comte de Montal appeared before Diksmuide; Ellenberg opened the sluice gates, while the Allied commander at Nieuwpoort broke the dykes, flooding the area around the town. This meant Diksmuide could only be assaulted from the east and while this was the weakest part of the defences, the position was considered 'serious but not desperate.'^[11]

Surrender

On 26 July, Montal began firing on the town; after only two days, Ellenberg held a council with his senior officers, and proposed they surrender the town, arguing further resistance was pointless.^[12] Eight officers signed the articles of surrender, including Colonel Graham, commander of a regiment in the elite Scots Brigade; the only exception was Major Robert Duncanson of Lorne's.^[13] On 29 July, Colonel O'Farrell, commander of the garrison at Deinze, also capitulated to a French force under Feuquières without a shot being fired.^[14]

By now, siege warfare was an exact art, the rules of which were so well understood wagering on the outcome and duration of a siege became a popular craze; in 1691, the then enormous sum of £200,000 was alleged to have been bet on the outcome of the Siege of Limerick.^[15] Professional honour demanded a defence, but so long as they surrendered once 'a practicable breach' had been made, garrisons were given generous terms.^[16] Contemporaries felt Diksmuide should have been held for at least eight days; its rapid capitulation was extremely unusual, especially as Ellenberg opened negotiations with the besiegers.^[13]

The terms of surrender meant the garrison became prisoners, rather than being allowed to keep their weapons, and free passage to Allied lines.^[17] One suggestion is that Ellenberg was a capable and reliable subordinate who could not exercise command on his own.^[18] This seems unlikely for an experienced senior officer, since taking or holding fortifications was the dominant form of warfare in this period.^[19] At his trial, Ellenberg later claimed "a panic seized him, which he could not get over, nor account for".^[20]

Graham and O'Farrell had served in the Scots Brigade since the 1670s and accompanied William to England in 1688; Deinze was held by O'Farrell's 'Fusiliers,' a designation reserved for elite units, which had fought at Walcourt, Steinkirk and Landen.^[21] While Deinze was simply a fortified village, William was furious neither of the garrisons had 'done their duty.'^[14] In his Diary entry for 8 December 1695, Constantijn Huygens, William's Secretary for Dutch affairs, suggests Ellenberg was bribed by the French.^[22]

Aftermath

Desertion and ill-discipline among enlisted men were ongoing issues in this period, due to poor conditions and irregular payment of wages; a lapse of commitment among senior officers was a much more serious problem. Evidence presented at the court martial indicates both Ellenberg and O'Farrell simply took the wrong decisions, but the defection of a group of experienced senior officers possibly indicates a wider issue of war weariness, or low morale.^[23]

Prisoners were normally exchanged as soon as possible, but the French refused William's demand in August for the return of the 6,000 - 7,000 troops captured at Diksmuide and Deinze, due to a dispute over the terms.^[24] All sides were short of manpower by this stage of the war; deserting to receive a signing-on bonus was common, particularly as these were paid immediately while wages were often months in arrears. Since the recruiters were paid a bounty for each enlistee, the financial benefits to the French officers involved were considerable.^[25]

One suggestion is this may have been a factor in the surrender; nearly 3,000 of the prisoners were forced into French regiments, and sent to fight in Italy or Catalonia.^[26] In retaliation, despite the garrison of Namur being allowed to surrender on terms, its commander Boufflers was not released until the remaining Allied prisoners were returned in September.^[17]

After their release, Duncanson was promoted for refusing to sign the surrender; the others were tried by a court martial, held between 10 and 25 October, headed by Sir Henry Belasyse.^[27] O'Farrell, Graham, and the others were either dismissed or sanctioned, but quickly reinstated; O'Farrell ended as a Major-General. Ellenberg was sentenced to death by beheading, and executed in Ghent on 30 November.^[28]
