The memorial lists 827 officers and men of the New Zealand Expeditionary Force with no known grave who died in or near Messines in 1917 and 1918. This period included the Battle of Messines. Context_6 : East Flanders (Dutch: "Oost-Vlaanderen" ] , French: "(Province de) Flandre-Orientale" , German: "Ostflandern" ) is a province of Flanders, one of the three regions of Belgium. It borders (clockwise from the North) on Zeelandic Flanders (the Netherlands) and (in Belgium) on the provinces of Antwerp, Flemish Brabant (both in Flanders), of Hainaut (Wallonia) and of West Flanders (Flanders). It has an area of 2,991km which is divided into six administrative districts ("arrondissementen" in Dutch) containing 65 municipalities. The provincial population is 1,408,484 and the capital is Ghent. Context_7 : The Battle of Messines (714 June 1917) was conducted by the British Second Army (General Sir Herbert Plumer), on the Western Front near the village of Messines in West Flanders, Belgium, during the First World War. The Nivelle Offensive in April and May had failed to achieve its more ambitious aims, had led to the demoralisation of French troops and dislocated the Anglo-French strategy for 1917. The offensive at Messines forced the Germans to move reserves to Flanders from the Arras and Aisne fronts, which relieved pressure on the French. The tactical objective of the attack at Messines was to capture the German defences on the ridge, which ran from Ploegsteert (Plugstreet) Wood in the south, through Messines and Wytschaete to Mt. Sorrel, to deprive the German 4th Army of the high ground south of Ypres. The ridge commanded the British defences and back areas further north, from which the British intended to conduct the Northern Operation, an advance to Passchendaele Ridge and then capture the Belgian coast up to the Dutch frontier. Context_8 : The mines in the Battle of Messines comprised a series of underground explosive charges, secretly planted by British tunnelling units beneath the German 4th Army lines near the village of Mesen ("Messines" in French, historically used in English) in Belgian West Flanders during the First World War. The mines were detonated at the start of the Battle of Messines (714 June 1917) , creating 19 large craters. The joint explosion of the mines at Messines 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 (General Sir Herbert Plumer), remarked to the press, "Gentlemen, we may not make history tomorrow, but we shall certainly change the geography". The Battle of Messines marked the zenith of mine warfare. On 10 August 1917, the Royal Engineers fired the last British deep mine of the war, at Givenchy-en-Gohelle near Arras.
