The Battle of Messines was a battle of the western front of World War I. It began on 7 June 1917 when the British Second Army under the command of General Herbert Plumer launched an offensive near the village of Mesen (Messines) in West Flanders, Belgium. The target of the offensive was a ridge running north from Messines village past Wytschaete village which created a natural stronghold southeast of Ypres. One of the key features of the battle was the detonation of 19 mines immediately prior to the infantry assault, a tactic which disrupted German defences and allowed the advancing troops to secure their objectives in rapid fashion.

The Battle of Messines was a battle of the western front of World War I. It began on 7 June 1917 when the British Second Army under the command of General Herbert Plumer launched an offensive near the village of Mesen (Messines) in West Flanders, Belgium. The target of the offensive was a ridge running north from Messines village past Wytschaete village which created a natural stronghold southeast of Ypres. One of the key features of the battle was the detonation of 19 mines immediately prior to the infantry assault, a tactic which disrupted German defences and allowed the advancing troops to secure their objectives in rapid fashion. The attack was also a prelude to the much larger Third Battle of Ypres, known as Passchendaele, which began on 11 July 1917.
Background
The assault on Messines ridge was conceived in early 1916, as Plumer sought ways to break German control of important strategic locations in the Ypres area. When it became apparent that the French offensive on the River Aisne would not succeed, General Douglas Haig reconceived the Messines operation as a precursor to a larger assault in the Ypres sector and ordered Plumer to proceed with the attack as soon as possible. Not only would capturing Messines Ridge give the British control of important strategic ground, it would also flatten out the southern flank of the Ypres Salient. This would both reduce the manpower needed to maintain the front, and reduce the German strategic and tactical advantages in the area.
Mining operations
Over a period beginning more than a year before the attack, Canadian, Australian, and British engineers had tunneled under the German trenches and laid 21 mines totaling 455 tonnes of ammonal explosive. To solve the problem of wet soil, the tunnels were made in the layer of "blue clay", 80–120 feet (25–30 m) below the surface. The galleries dug in order to lay these mines totalled over in length, and had been constructed in the face of tenacious German counter-mining efforts. On several occasions, German tunnelers were within metres of large British mine "chambers". One mine was found by the Germans, and the chamber was wrecked by a countermine.
The largest of the 21 Messines mines was at Spanbroekmolen; the "Lone Tree Crater" formed by the blast was approximately 250 feet (80 m) in diameter, and 40 feet (12 m) deep. The mine consisted of 41 tons of ammonal explosive, located in a chamber dug 88 feet (27 m) below ground.
Opposing forces
On the British side, the assault was conducted entirely by the three corps of Plumer's British Second Army. On the northern edge of the sector was the British X Corps—under the command of Thomas Morland—comprising the 23rd, 47th and 41st Divisions. In the centre was the British IX Corps—commanded by Alexander Hamilton-Gordon—consisting of the 19th British, 16th Irish and 36th Ulster Divisions. To the southeast, Alexander Godley commanded the II Anzac Corps—composed of the 25th British, 1st New Zealand and 3rd Australian Divisions. Each of these corps held a fourth division in reserve—the 24th for the X, the 11th for the IX, and the 4 Australian for the II Anzac—for use in follow-up attacks.
Opposing Plumer's Second Army were forces of the German Fourth Army, under the command of Friedrich Bertram Sixt von Armin. To the northeast, the 204th and 35th divisions defended Hill 60 and Battle Wood. In the centre, the 2nd and 3rd Bavarian Divisions defended Messines and Wytschaete. In the southeast, the southern banks of the River Douve were defended by the 4th Bavarian Division. The German defenses relied on an "elastic" defense method; the front-lines were lightly defended, with heavier defensive bunkers up to half a mile behind the front lines.
The battle
The operation plan for the attack on Messines Ridge called for heavy artillery strikes before zero hour. At 3AM, the mines would be detonated; followed by a frontal assault of nine infantry divisions aimed at securing the ridge. In the week before the attack began, some 2,200 artillery guns bombarded the German trenches with an estimated 3–4 million shells. Equipped with up-to-date and intricate maps of the battlefield, British artillery succeeded in destroying close to 90% of the German field-gun positions on Messines Ridge.
Detonation of the mines
At 02:50am on 7 June, the artillery bombardment ceased. Expecting an immediate infantry assault, German defenders returned to their forward positions. At 3:10am, the mines were detonated, killing approximately 10,000 German soldiers and destroying most of the fortifications on the ridge, as well as the town of Messines itself. Reports were made that the shockwave from the explosion was heard as far away as London and Dublin. To make matters worse for the Germans, the explosions occurred while the front line troops were being relieved, meaning both groups (relieving and relieved) were caught in the blasts.
Assault
Following the explosions, British, Australian and New Zealand troops from three corps (II ANZAC, IX and X) advanced on the Messines salient from three sides. The front lines were overrun without opposition. German troops surrendered "in droves", and the first series of objectives had been secured almost entirely within three hours. Advancing on the southern flank, the New Zealand Division captured the village of Messines proper, despite intricate layers of fortifications beyond the front line. In the center section, to the north, the 36th (Ulster) Division and 16th (Irish) Division advanced in tandem, the Irish capturing the village of Wytschaete and pushing forward to secure their objectives. Many considered this joint effort to be of considerable political significance, given the turmoil in Ireland at the time. The Irish Nationalist Party MP Major William Redmond was fatally wounded in this action. The most serious resistance was in the northern sector, where the 47th (1/2nd London) Division had to navigate across the Ypres-Comines canal. This obstacle slowed the advance considerably, but the Londoners had secured all their objectives by mid-morning, and the goals of the first phase were achieved by 10:00am at all points on the line of attack.
Once the first series of objectives was secured, more than forty batteries of artillery were brought forward to support the second phase of the attack. Bombardment continued for several hours, and at approximately 3:00pm the reserve divisions, supported by tanks, advanced towards the second line of objectives. In just over an hour, all these were secured At 11:00AM, German troops counterattacked at several points along the new British lines. Although British troops had had very little time to consolidate their positions, the German attacks were easily repulsed and ultimately resulted in further territorial gains. Heavy British artillery strikes on 10 June meant that further counterattacks—already being planned and prepared by German commanders—never materialized.
There were 4 Victoria Crosses awarded during the battle, two in the Australian 3rd Division (to Private John Carroll and Captain Robert Cuthbert Grieve), one in the New Zealand Division (to Lance-Corporal Samuel Frickleton) and one in the 25th Division (to Private William Ratcliffe).
Aftermath
The operation was almost totally successful. Meticulously planned, and well executed, the assault secured all its objectives in less than twelve hours, took more than 7,000 prisoners, and suffered a relatively modest 24,000 total casualties. The combination of tactics proven in other sectors - notably the use of mines, creeping barrages, and small-unit tactics - allowed for almost complete surprise and rapid advances. The offensive also secured the southern end of the Ypres salient in preparation for the subsequent offensive in that area.
Although the operation was successful, it had the effect of over-inflating expectations for the Passchendaele offensive. While Messines led Haig and other British commanders to believe that success could be had relatively cheaply in the main offensive as well, the circumstances of the operations were substantially different, and attempts to apply similar tactics would result in a general failure.
Not all of the mines that had been laid were detonated. Two of the original 21 mines were not ignited. On 17 July 1955, a lightning strike set off one of the remaining mines. There were no human casualties, but one cow was killed. The 21st mine—the mine abandoned due to its discovery by German counter-miners—is believed to have been found, but no attempt has been made to remove it.
