Wulverghem

Spanbroekmolen is a small group of farms in Heuvelland, a municipality located in the Belgian province of West Flanders. The hamlet is sited on one of the highest points of the Messines Ridge, in between the villages of Kemmel, Wijtschate and Wulvergem.

The Mines in the Battle of Messines comprised a series of underground explosive charges which were fired during the First World War at the start of the Battle of Messines (7–14 June 1917) by the British Second Army (General Sir Herbert Plumer) near the village of Mesen (Messines in French, historically also used in English and German) in Belgian West Flanders. The mines, secretly planted and maintained by British tunnelling units beneath the forward position of the German 4th Army (General Friedrich Bertram Sixt von Armin), killed approximately 10,000 German soldiers and created 19 large craters. Their joint explosion ranks among the largest non-nuclear explosions of all time. The evening before the attack, General Sir Charles Harington, Chief of Staff of the Second Army, remarked to the press, "Gentlemen, I don’t know whether we are going to make history tomorrow, but at any rate we shall change geography". The Battle of Messines marked the zenith of mine warfare. Just over two months later, on 10 August 1917, the Royal Engineers fired the last British deep mine of the war, at Givenchy-en-Gohelle near Arras.

The Gas attacks at Wulverghem (30 April and 17 June 1916) were German cloud gas releases during the First World War on British troops at Wulverghem in the municipality of Heuvelland, near Ypres in the Belgian province of West Flanders. The gas attacks were part of the sporadic fighting between battles in the Ypres Salient on the Western Front. The British Second Army held the ground from Messines Ridge northwards to Steenstraat and the divisions opposite the German XXIII Reserve Corps had received warnings of a gas attack. From 21 to 23 April, British artillery-fire exploded several gas cylinders in the German lines around Spanbroekmolen, which released greenish-yellow clouds. A gas alert was given on 25 April when the wind began to blow from the north-east and routine work was suspended; on 29 April, two German soldiers deserted and warned that an attack was imminent. Just after midnight on 30 April, the German attack began and over no man's land, a gas cloud drifted on the wind into the British defences, then south-west towards Bailleul. The gas used at Wulverghem was a mixture of chlorine and phosgene, which had been used against British troops on 19 December 1915 in the phosgene attack at Wieltje, north-east of Ypres. This and earlier gas attacks, beginning at the Second Battle of Ypres (21 April – 25 May 1915) had given the British time to replace improvised gas masks with effective mass-produced versions, obtain other anti-gas equipment and to establish anti-gas procedures. Helmets impregnated with chemicals to neutralise chlorine had been issued in several variants, each more effective than the last. By April 1916, British troops had PH helmets and some specialist troops like machine-gunners, were equipped with box respirators. The German gas attack at Wulverghem on 30 April, caused the defenders 562 gas casualties and 89 gas fatalities but German raiding parties, looking for mine entrances to destroy, were repulsed with small-arms and artillery fire. A second attempt by the Germans on 17 June caused about the same number of gas casualties but the British again easily repulsed German patrols.

The Kemmelberg (English: Kemmel Hill, French: Mont Kemmel) is a hill formation in Flanders, Belgium. It is located less than a kilometer from the village of Kemmel, part of the municipality of Heuvelland in the province of West Flanders. The Kemmelberg is the highest point in the province with an altitude of 154 metres (505 ft), this is the geodetic point with mark Ch63.1, as measured by the National Geographical Institute (NGI) in Brussels in October 1951 via optical levelling.

Ploegsteert (Picard: Ploster) is a village of Wallonia and a district of the municipality of Comines-Warneton, located in the province of Hainaut, Belgium. It is the most westerly settlement of Wallonia. It is approximately 2 kilometres (1.2 mi) north of the French border. Created in 1850 on part of the territory of Warneton, it includes the hamlet of Le Bizet, which is the border with France (there is also a hamlet named "Le Bizet" in France). It is largely francophone, with facilities for Dutch speakers. In late 1914 and early 1915, the nearby Ploegsteert Wood was the site of fierce WWI fighting. Today there are numerous cemeteries and memorials, including the Hyde Park Corner (Royal Berks) CWGC Cemetery and the Berks CWGC Cemetery Extension with the Ploegsteert Memorial to the Missing, which commemorates more than 11,000 British and Empire servicemen who died outside the Ypres Salient and have no known grave. From January to May 1916, Winston Churchill served in the area as Commanding Officer (Lieutenant-Colonel) of the 6th Battalion of the Royal Scots Fusiliers. Another nearby burial ground is the Lancashire Cottage Cemetery. As part of Comines-Warneton, Ploegsteert was declared a sister city of Wolverton, Buckinghamshire, England, in 2006; this was partly initiated through the finding of letters from a 16-year-old soldier from Wolverton named Albert French. He is buried in Hyde Park Corner (Royal Berks) Cemetery, just outside the village. The village is home to a carpentry museum.

The Battle of Messines was fought in October 1914 between the armies of the German empire and British empire and France as part of the Race to the Sea, between the river Douve and the Comines–Ypres canal.

Croonaert Wood is a location in the municipality of Heuvelland near Ypres, Belgium. It is a lightly forested area known for the Bayernwald Trenches open-air museum located there.

Ploegsteert Wood was a sector of the Western Front in Flanders in World War I, part of the Ypres Salient. It is located around the Belgian village of Ploegsteert, Wallonia. After fierce fighting in late 1914 and early 1915, Ploegsteert Wood became a quiet sector where no major action took place. Units were sent here to recuperate and retrain after tougher fighting elsewhere, and before returning to take part in more active operations. British Tommies referred to Ploegsteert Wood as "Plugstreet Wood". From January to May 1916, Winston Churchill served in the area as Commanding Officer (Lieutenant-Colonel) of the 6th Battalion of the Royal Scots Fusiliers. There are numerous Commonwealth War Graves Commission (CWGC) cemeteries and memorials around the wood, including the Hyde Park Corner (Royal Berks) CWGC Cemetery and the Berks CWGC Cemetery Extension with the Ploegsteert Memorial to the Missing. The Ploegsteert Memorial commemorates more than 11,000 British and Empire servicemen who died during the First World War and have no known grave. It is one of several CWGC Memorials to the Missing along the Western Front. Those lost within the Ypres Salient without a known grave are commemorated at the Menin Gate and Tyne Cot Memorial to the Missing, while the missing of New Zealand and Newfoundland are honoured on separate memorials.
