Sint-Elooi

The Actions of St Eloi Craters from 27 March to 16 April 1916, were local operations in the Ypres Salient of Flanders, during the First World War by the German 4th Army and the British Second Army. Sint-Elooi (the French St Eloi is commonly used in English) is a village about 5 km (3.1 mi) south of Ypres in Belgium. The British dug six galleries under no man's land, placed large explosive charges under the German defences and blew them at 4:15 a.m. on 27 March. The 27th Division captured all but craters 4 and 5. The 46th Reserve Division counter-attacked but the British captured craters 4 and 5 on 30 March. The Canadian Corps took over, despite the disadvantage of relieving troops in action. The Canadians inherited positions in a deplorable state, the British having pressed their advantage, rather than consolidating the captured ground. On the night of 5/6 April a German methodical attack (Gegenangriff) recovered the captured craters. Canadian runners struggled to deliver messages and for several days the Canadian and British staffs were ignorant of which craters had been captured, the topography having been changed so much by the mine detonations. There were 17 craters, the new ones superimposed on the old, the ground full of shell-holes and derelict trenches. Snipers made it impossible to orientate and fresh troops easily mistook one pair of craters for another. The Canadians counter-attacked several times, then concentrated on consolidating the front line, ready for another attempt. Constant rain, oozing mud and incessant artillery-fire exhausted troops quickly and battalions had to be relieved after a couple of days. Canadian and British staffs were still ignorant of the German capture of craters 4 and 5. Conflicting reports added to the uncertainty but a reconnaissance by a Canadian major on 10 April found that the Germans were in crater 4. On 16 April, the Royal Flying Corps (RFC) photographed the area, showing the Germans in craters 2, 3, 4 and 5 and a trench round the front lips. Plans to attack were cancelled and for two weeks both sides exchanged artillery-fire. The mud and poor weather caused unprecedented misery on the troops but the first attack showed that with preparation, surprise and good timing a limited objective could be captured. The British had attacked with tired troops and had not achieved all of their objectives and the second attempt was at the cost of quick consolidation. At St Eloi, against an attack on a narrow front, where the defender had good observation, the ground could not be held. It was an open question as to what width of front to attack, narrow enough to guarantee success, yet wide enough to force the Germans to disperse their artillery-fire so that captured ground could be held.

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.

Francis Nathaniel Tarr (14 August 1887 – 18 July 1915) was an English international rugby union player. He played centre for the Leicester Tigers and, between 1909 and 1913, won four caps for England, scoring two tries. He also earned three Blues while reading law at Oxford. He later became a solicitor in Leicester before volunteering for overseas service during the First World War. He was killed in July 1915 near Ypres on the Western Front, after being hit by a shell splinter while serving as a lieutenant in the 1/4th Battalion, Leicestershire Regiment. Tarr was one of 27 former England internationals killed in the war.

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.

Zillebeke (also known as Zellebeck) is a village in the Flemish province of West Flanders in Belgium. It is a former municipality which is now part of Ypres.

The Museum Godshuis Belle is a small museum in Ypres. Located in the chapel of an old almshouse, it houses the art collection of the Ypres Public Centre for Social Welfare (OCMW in Dutch).

Ieper railway station is located in Ypres (Dutch: Ieper) in West Flanders, Belgium. The station was opened in 1854 during the reign of Leopold I of Belgium. It is located on the line from Kortrijk to Poperinge run by NMBS, Belgian railway line 69.

The siege of Ypres (1–18 June 1794) saw a Republican French army commanded by Jean-Charles Pichegru invest the fortress of Ypres and its 7,000-man garrison composed of Habsburg Austrians under Paul von Salis and Hessians led by Heinrich von Borcke and Georg von Lengerke. French troops under Joseph Souham fended off three relief attempts by the corps of François Sébastien Charles Joseph de Croix, Count of Clerfayt. Meanwhile, the French besiegers led by Jean Victor Marie Moreau compelled the Coalition defenders to surrender the city. The fighting occurred during the War of the First Coalition, part of the Wars of the French Revolution. In 1794 Ypres was part of the Austrian Netherlands, but today it is a municipality in Belgium, located about 120 kilometres (75 mi) west of Brussels. In the Flanders Campaign of 1794, the Coalition army made its main drive against the French center while the French attacked on the two flanks. The Coalition was successful at first but the French soon seized the initiative with persistent attacks. When the Coalition forces shifted east to defend the line of the Sambre River at the end of May, the left wing of Pichegru's Army of the North laid siege to Ypres. Clerfayt's outnumbered corps found itself unable to defend the western flank. A week after Ypres fell, the French won a critical victory on the eastern flank at the Battle of Fleurus.

The siege of Ypres in the Spanish Netherlands took place between March 18 and March 25, 1678, as part of the Franco-Dutch War, and ended with the conquest of the city by the French.

The Battle of Hill 60 (17 April – 7 May 1915) took place near Hill 60 south of Ypres on the Western Front, during the First World War. Hill 60 had been captured by the German 30th Division on 11 November 1914, during the First Battle of Ypres (19 October – 22 November 1914). Initial French preparations to raid the hill were continued by the British 28th Division, which took over the line in February 1915 and then by the 5th Division. The plan was expanded into an ambitious attempt to capture the hill, despite advice that Hill 60 could not be held unless the nearby Caterpillar ridge was also occupied. It was found that Hill 60 was the only place in the area not waterlogged and a French 3 ft × 2 ft (0.91 m × 0.61 m) mine gallery was extended. Experienced miners from Northumberland and Wales were recruited for the digging and the British attack began on 17 April 1915. The hill was captured quickly with only seven casualties but then it was found that the salient which had been created, made occupation of the hill very costly. Both sides mistakenly accused the other of using poison gas in the April fighting; German attacks on the hill in early May included the use of gas shells and the Germans recovered the ground at the second attempt on 5 May. It remained in German hands until the Battle of Messines in 1917, when two of the Mines in the Battle of Messines were detonated beneath Hill 60 and the Caterpillar.

Ypres ( EE-prə, French: [ipʁ]; Dutch: Ieper [ˈipər] (listen); West Flemish: Yper; German: Ypern [ˈyːpɐn] (listen)) is a Belgian city and municipality in the province of West Flanders. Though the Dutch name Ieper is the official one, the city's French name Ypres is most commonly used in English. The municipality comprises the city of Ypres/Ieper and the villages of Boezinge, Brielen, Dikkebus, Elverdinge, Hollebeke, Sint-Jan, Vlamertinge, Voormezele, Zillebeke, and Zuidschote. Together, they are home to about 34,900 inhabitants. During the First World War, Ypres (or "Wipers" as it was commonly known by the British troops) was the centre of the Battles of Ypres between German and Allied forces.

The Cloth Hall (Dutch: Lakenhal/Lakenhalle) is a large cloth hall, a medieval commercial building, in Ypres, Belgium. It was one of the largest commercial buildings of the Middle Ages, when it served as the main market and warehouse for the Flemish city's prosperous cloth industry. The original structure, erected mainly in the 13th century and completed 1304, lay in ruins after artillery fire devastated Ypres in World War I. Between 1933 and 1967, the hall was meticulously reconstructed to its prewar condition, under the guidance of architects J. Coomans and P. A. Pauwels. At 125 metres (410 ft) in breadth, with a 70 metres (230 ft)-high belfry tower, the Cloth Hall recalls the importance and wealth of the medieval trade city. The building now houses the In Flanders Fields Museum. In 1999, it was inscribed on the UNESCO World Heritage List as part of the Belfries of Belgium and France site, in recognition of their unique architecture, role in the advancement of civil liberties, and their civic, not religious, influence.
