The Battle of the Yser (French: Bataille de l'Yser, Dutch: Slag om de IJzer) was a battle which took place in October 1914 between the towns on Nieuwpoort and Diksmuide along a 35-kilometre (22 mi) long stretch of the Yser river and Yperlee canal in Belgium.[1] The front line was held by a large Belgian force which succeeded in halting the German advance, though only after heavy losses. After two months of defeats and retreats, the battle of Yser finally halted the invasion that gave the Germans control of over 95 percent of Belgian territory. Victory in the battle allowed Belgium to retain control of a sliver of territory, while making King Albert a Belgian national hero, sustaining national pride and providing a venue for commemorations of heroic sacrifice for the next century.


Strategic developments

On 2 August 1914, the Belgian government refused passage through Belgium to German troops and on the night of 3/4 August the Belgian General Staff ordered the 3rd Division to Liège to obstruct a German advance. The German army invaded Belgium on the morning of 4 August.[2] Covered by the 3rd Division, the Liège fortress garrison, a screen of the Cavalry Division and detachments from Liège and Namur, the Belgian field army closed up to the river Gete and by 4 August the 1st Division had assembled at Tienen, the 5th Division at Perwez, the 2nd Division at Leuven and the 6th Division at Wavre, covering central and western Belgium and the communications towards Antwerp. German cavalry appeared at Visé early on 4 August to find the bridge down and Belgian troops on the west bank. The Germans crossed at a ford and forced the Belgians to retire towards Liège. By the evening it was clear to the Belgian High Command that the 3rd Division and the Liège garrison were in the path of a very large invasion force.[3]

With information that five German corps and six reserve corps were in Belgium and with no immediate support available from the French army and British Expeditionary Force (BEF), the Belgian field army was ordered to withdraw towards Antwerp on the evening of 18 August and arrived on 20 August after an engagement between the 1st Division and the German IX Corps near Tienen, in which the Belgians had 1,630 casualties.[4][5] The Belgian government of Charles de Broqueville left Brussels for Antwerp and the Belgian capital was occupied unopposed on 20 August, as the Belgian field army completed the retirement to Antwerp. Namur fell on 24 August, as the field army made a sortie from Antwerp towards Brussels.[6][7] The Germans detached the III Reserve Corps from the 1st Army to mask the city and a division of the IV Reserve Corps to occupy Brussels.[8][9]

Belgian soldiers in 1914

On 1 October Beseler ordered an attack on forts Sint-Katelijne-Waver, Walem and the Bosbeek and Dorpveld redoubts by the 5th Reserve and Marine divisions. By 11:00 a.m. fort Walem was severely damaged, fort Lier had been hit by a 16-inch (410 mm) shell, fort Koningshooikt and the Tallabert and Bosbeek redoubts were mostly intact and the intervening ground between Fort Sint-Katelijne-Waver and Dorpveld redoubt had been captured. A counter-attack failed and the 4th Division was reduced to 4,800 infantry. The Belgian commanders ordered the left flank of the army to withdraw to a line of defence north of the Nete, which covered the gap in the outer defences and kept the city out of range of German super-heavy artillery. Proclamations warning the inhabitants that King Albert I and his Government would leave Antwerp, were put up during the day.[10] Early on 9 October, German troops found some forts of the inner ring empty; Beseler had the bombardment stopped and summoned the Military Governor, General Deguise to surrender. The last c. 30,000 men of the Antwerp garrison surrendered and the city was occupied by German troops. 33,000 soldiers of the Antwerp garrison (about 13 of the Belgian Army) fled north to the Netherlands, where they were interned.[11]

During the siege of Antwerp, the German and French armies fought the Battle of the Frontiers (7 August–13 September) and then the German armies in the north, pursued the French and the BEF southwards into France in the Great Retreat, which culminated in the First Battle of the Marne (5–12 September), which was followed by the First Battle of the Aisne (13 September – 28 September). A series of reciprocal attempts by the Franco-British and German armies to envelop the northern flank of the opposing army, the Race to the Sea took place through Picardy, Artois and Flanders from (17 September – 19 October). The "race" ended on the North Sea coast of Belgium, when the last open area from Dixmude to the North Sea was occupied by Belgian troops from Antwerp.[12]

Tactical developments

Fall of Antwerp and the Allied retreat, 1914

British and French forces in Belgium covered the retirement of the Belgians and British from Antwerp.[13] The 1st, 3rd and 4th divisions reached Ostend, the 5th and 6th divisions arrived at Torhout and Diksmuide and the Antwerp garrison troops moved to an area north-west of Ghent. The Germans at Antwerp had not discovered the retirement and the 4th Ersatz Division and Landwehr troops at Lokeren and Moerbeke, turned east towards the city before the withdrawal was discovered. The III Reserve Corps and the 4th Ersatz Division were then ordered to turn west and advance on Kortrijk, to prolong the main German front, before being sent towards Ghent and Bruges, with orders to reach Blankenberge and Ostend on the coast. On 11 October, German troops were detected advancing on Ghent, by when the Belgian fortress troops had joined the field army. A withdrawal from Ghent from 3:00–10:00 p.m. began, after which German troops entered the city. Several bridges were demolished during the retirement, although crowds of civilians on the main road and rail bridges led to them being left intact.[14]

French fusilier marins at the Yser

By 18 October the Belgian, British and French troops in northern France and Belgium had formed a defensive line, with the British II Corps in position, with the 5th Division from La Bassée Canal north to Beau Puits, the 3rd Division from Illies to Aubers and three divisions of the French Cavalry Corps of General Conneau in position from Fromelles to Le Maisnil, the British III Corps with the 6th Division from Radinghem to Epinette and the 4th Division from Epinette to Pont Rouge, the BEF Cavalry Corps with the 1st and 2nd Cavalry divisions, from Deulemont to Tenbrielen, the British IV Corps with the 7th Division and 3rd Cavalry Division from Zandvoorde to Oostnieuwkirke, the French Groupe Bidon and the de Mitry Cavalry Corps from Roulers to Cortemarck, the 87th and 89th Territorial divisions from Passchendaele to Boesinghe and then the Belgian field army and fortress troops from Boesinghe to Nieuport, with the Fusiliers Marin brigade at Dixmude.[15]

Flanders terrain

The North-west of France and the south-west Belgium is known as Flanders. West of a line between Arras and Calais in the north-west, lie chalk downlands covered with soil sufficient for arable farming. East of the line, the land declines in a series of spurs into the Flanders plain, bounded by canals linking Douai, Béthune, St. Omer and Calais. To the south-east, canals run between Lens, Lille, Roubaix and Courtrai, the Lys river from Courtrai to Ghent and to the north-west lies the sea. The plain is almost flat, apart from a line of low hills from Cassel, east to Mont des Cats, Mont Noir, Mont Rouge, Scherpenberg and Mount Kemmel. From Kemmel, a low ridge lies to the north-east, declining in elevation past Ypres through Wytschaete, Gheluvelt and Passchendaele, curving north then north-west to Dixmude where it merges with the plain. A coastal strip about 10 miles (16 km) wide, is near sea level and fringed by sand dunes. Inland the ground is mainly meadow, cut by canals, dykes, drainage ditches and roads built up on causeways. The Lys, Yser and upper Scheldt have been canalized and between them the water level underground is close to the surface, rises further in the autumn and fills any dip, the sides of which then collapse. The ground surface quickly turns to a consistency of cream cheese and on the coast troops were confined to roads, except during frosts.[16]

View of the flooding in Ramskapelle

The rest of the Flanders Plain is woods and small fields, divided by hedgerows planted with trees and cultivated from small villages and farms. The terrain was difficult for infantry operations because of the lack of observation, impossible for mounted action because of the many obstructions and difficult for artillery because of the limited view. South of La Bassée Canal around Lens and Béthune was a coal-mining district full of slag heaps, pit-heads (fosses) and miners' houses (corons). North of the canal, the cities of Lille, Tourcoing and Roubaix form a manufacturing complex, with outlying industries at Armentières, Comines, Halluin and Menin, along the Lys river, with isolated sugar beet and alcohol refineries and a steel works near Aire. Intervening areas are agricultural, with wide roads on shallow foundations and unpaved mud tracks in France and narrow pavé roads along the frontier and in Belgium. In France, the roads were closed by the local authorities during thaws to preserve the surface and marked by Barrières fermėes, which were ignored by British lorry drivers. The difficulty of movement after the end of summer absorbed much of the labour available, on road maintenance, leaving field defences to be built by front-line soldiers.[17]


Positions of the Belgian divisions on 16 October 1914

The Belgian army retirement continued on 11 and 12 October, covered by cavalry, cyclists and motor machine-gun sections. On 14 October, the Belgian army began to dig in along the Yser, the 6th and 5th divisions to the north of French territorial divisions, assembled at Boesinghe, then northwards along the Yser canal to the Fusiliers Marins at Dixmude. The 4th, 1st and 2nd divisions prolonged the line north, with advanced posts at Beerst, Keyem, Schoore and Mannekensvere, about 1-mile (1.6 km) forward on the east bank. A bridgehead was also held near the coast around Lombartzyde and Westende to cover Nieuport, with the 2nd Cavalry Division in reserve.[18] On 18 October, the French 87th and 89th Territorial Infantry divisions took over the defence of the front line south of Fort Knokke from the 6th Belgian division, which is moved to the Yser Front. On 21 October, the hard-pressed Belgian Army was reinforced with the French 42nd Division under command of Paul François Grossetti.
The Allies assembled a naval force under the British Admiral Horace Hood with three monitors, (Severn, Humber and Mersey) and assorted other craft. to provide heavy artillery support to the Allied defenders of the seaward flank.[19]

The German forces comprised the newly organized German Fourth Army, commanded by the Duke of Württemberg, with the III Reserve Corps from Antwerp and four new reserve corps from Germany, along with cavalry and heavy artillery units. It moved southwards from Bruges and Ostend in the direction of the Yser river, to take the line from Nieuwpoort to Ypres.[20]


Yser inundations, 1914

Diksmuide was attacked on 16 October and defended by Belgian and French troops under Colonel Alphonse Jacques who would later be awarded the title "de Dixmude" for his role in the defence of the town. Despite heavy losses, the Belgians and French held the town. The press, politicians, literary figures and the military channelled public opinion, making out that the defence of the town was both strategic and heroic.[21]

On 18 October the German offensive began and overran Allied troops from Nieuwpoort south to Arras in France. The objective was to defeat the Belgian and French armies and to deprive the British of access to Calais, Boulogne and Dunkirk. The III Reserve Corps attacked Belgian defences from Diksmuide to the sea, regardless of loss. The Germans captured advanced posts at Keiem, Schoore and part of Mannekensvere and reached the Yser, despite fire support from the Anglo-French flotilla, which bombarded German troops along the coast as far as Middelkerke. The 4th Ersatz Division was forbidden to cross the Yser at Nieuwpoort because of the shell-fire from the Allied ships.[22]

On 21 October, the Germans were able to establish a small bridgehead on the west bank, despite a counter-attack by the newly arrived French 42nd Division and the last bridge was blown up on 23 October. Diksmuide bore the brunt of repeated German offensives and bombardments, yet the town was still not taken. The French high command planned to flood large parts of their territory as a defensive measure. This would have put the Belgian army in the impossible choice of being trapped between the flood and the Germans, or else abandoning the last part of unoccupied Belgium. The plan was postponed, since the Belgian army had started preparations to flood the area between the Yser and its tributary canals. On 25 October, the German pressure on the Belgians was so great, that a decision was taken to inundate the entire Belgian front line. After an earlier failed experiment on 21 October, the Belgians managed to open the sluices at Nieuwpoort during the nights of 26–29 October during high tides, steadily raising the water level until an impassable flooded area was created about 1-mile (1.6 km) wide, stretching as far south as Diksmuide.[23] [Notes 1]

The Germans launched another large attack on the Yser on 30 October. The attack punched through the Belgian second line and reached Ramskapelle and Pervijze.[24] The attack was stalled by Belgian and French counter-attacks which recovered Ramskapelle. The final attack, planned for the next day was called off, when the attacking Germans became aware of the flooding of the land in their rear. They withdrew in the night before 31 October.[25] On 10 November, Diksmuide fell and the fighting continued until 22 November further south, in the First Battle of Ypres.[26]



The German army failed to defeat the Belgian army and the retention of the last corner of Belgium ended the Race to the Sea and the period of open warfare. The stabilized front line along the Yser river became known as the Yser Front and continued to be held by Belgian forces until 1918 with little movement.

The struggle of the Belgian army to hold on to its territory during the remainder of the war and the experiences of ordinary Flemish infantrymen, led to an increase in Flemish national sentiment and the foundation of the Frontbeweging, the first party of the Flemish Movement, in 1917.[27]


In 1925 in the British Official History, J. E. Edmonds wrote that German records indicated that from (18 October – 30 November) between Gheluvelt and the coast, German casualties were c. 76,250 men.[28] In 2010 Sheldon wrote that from 18–30 October, the Belgian army had 20,000 casualties and that German casualties may have been much greater.[29]
