Field Marshal Sir Douglas Haig, commander of the British Expeditionary Force (BEF), did not receive approval for the Flanders operation from the War Cabinet until 25 July. He told his army commanders that “opportunities for the employment of cavalry in masses are likely to offer.”. The British and French commanders on the Western Front had to reckon on the German western army (Westheer) being strengthened by reinforcements from the Ostheer on the Eastern Front by late 1917. Matters of dispute by the participants, writers and historians since 1917 include the wisdom of pursuing an offensive strategy in the wake of the Nivelle Offensive, rather than waiting for the arrival of the American Expeditionary Force (AEF) in France. A French assault, called the Nivelle Offensive, had ended in disastrous failure in May 1917, spurring General Haig on to push for a major British offensive. [62] Gough laid down a new infantry formation of skirmish lines to be followed by "worms" on 24 August and Cavan noted that pillboxes should be attacked on a broad front, to engage them simultaneously. Even limited success would improve the tactical situation in the Ypres salient, reducing the exceptional wastage, even in quiet periods. Ironically, the mud also saved lives, cushioning many of the shells that landed and preventing their explosion. In 1918 all the ground that had been gained there by the Allies was evacuated in the face of a looming German assault. It eventually became so deep that men and horses drowned in it. Careful investigation of records of more than eighty years showed that in Flanders the weather broke early each August with the regularity of the Indian monsoon: once the Autumn rains set in difficulties would be greatly enhanced....Unfortunately, there now set in the wettest August for thirty years. It owed much to the surprise effect of 19 huge mines that were simultaneously fired. [97] Each of the three German ground-holding divisions attacked on 26 September, had an Eingreif division in support, twice the ratio of 20 September. [26] Ypres is 66 ft (20 m) above sea level; Bixschoote 4 mi (6.4 km) to the north is at 28 ft (8.5 m). After the dry spell in early September, British advances had been much quicker and the final objective was reached a few hours after dawn, which confounded the German counter-attack divisions. [114][d], The French First Army and British Second and Fifth armies attacked on 9 October, on a 13,500 yd (7.7 mi; 12.3 km) front, from south of Broodseinde to St Jansbeek, to advance half of the distance from Broodseinde ridge to Passchendaele, on the main front, which led to many casualties on both sides. The area was subjected to constant German artillery bombardments and its vulnerability to attack led to a suggestion by Brigadier C. F. Aspinall, that either the British should retire to the west side of the Gheluvelt Plateau or advance to broaden the salient towards Westroosebeke. [51] The main attack, by II Corps across the Ghelveult Plateau to the south, confronted the principal German defensive concentration of artillery, ground-holding divisions (Stellungsdivisionen) and Eingreif divisions. The British had 575 heavy and medium and 720 field guns and howitzers, more than double the quantity of artillery available at the Battle of Pilckem Ridge. He suggested that the southern attack from St Yves to Mont Sorrel should come first and that Mont Sorrel to Steenstraat should be attacked within 48–72 hours. Haig was heavily criticised for the attack and for failing to modify his plans as the attack clearly was not going to be a success. The British were further encouraged by the success of the attack on Messines Ridge on 7 June 1917. The Battle of Menin Road Ridge, along with the Battle of Polygon Wood on 26 September and the Battle of Broodseinde on 4 October, established British possession of the ridge east of Ypres. From 6:00 p.m. on 31 July to 6:00 p.m. on 4 August, there was another 63 mm (2 in) of rain. German attempts to reinforce the attacking troops failed, due to British artillery observers isolating the advanced German troops with artillery barrages. But to the army’s surprise, the German army fought well and Allied gains were not as large as expected. Heavy artillery bombarded the ruins of Polderhoek Château and the pillboxes in the grounds to mislead the defenders and the attack was made in daylight as a ruse to surprise the Germans, who would be under cover sheltering from the routine bombardments. The German attack was defeated by small-arms fire and the British artillery, whose observers had seen the SOS rockets. [102] North of the covert near Polygon Wood, deep mud smothered German shells before they exploded but they still caused many casualties. Gough held meetings with his corps commanders on 6 and 16 June, where the third objective, which included the Wilhelmstellung (third line), a second-day objective in earlier plans, was added to th… On November 6, however, Canadian troops advanced the few hundred yards necessary to occupy the site of what had been the village of Passchendaele (northeast of Ypres, about 5 miles [8 km] from the nearest front on the salient when the offensive had begun on July 31). The ridge had woods from Wytschaete to Zonnebeke giving good cover, some being of notable size, like Polygon Wood and those later named Battle Wood, Shrewsbury Forest and Sanctuary Wood. The Germans used mustard gas to assist them and the attempted Allied breakthrough to Passchendaele Ridge failed to materialise. OHL had issued orders to change tactics again days before Loßberg was blamed for giving new orders to the 4th Army. Then in the early days of August, the area was saturated with the heaviest rain the region had seen in thirty years. Ultimately, however, Currie had little choice. The preparations took several weeks and gave the troops some respite from vain sacrifice. [78], Plumer arranged for the medium and heavy artillery reinforcements reaching Flanders to be added to the creeping bombardment, which had been impossible with the amount of artillery available to the Fifth Army. To their left were units from the French First Army led by Anthoine and to Gough’s right was the Second Army led by the victor of Messines, Sir Herbert Plumer. The Battle of Passchendaele was one of the biggest battles of the First World War. Two battalions of the 2nd New Zealand Brigade of the New Zealand Division attacked the low ridge, from which German observers could view the area from Cameron Covert to the north and the Menin road to the south-west. [131][e], On 18 November the VIII Corps on the right and II Corps on the left (northern) side of the Passchendaele Salient took over from the Canadian Corps. By now, those German soldiers who had been fighting on the Eastern Front had been moved to the Western Front – and they had been specifically moved to Passchendaele Ridge to bolster the German forces there. Haig argued that any German loss of men was of greater importance than British loss as the Allies could sustain more losses as America had joined the war by the end of Passchendaeleeval(ez_write_tag([[300,250],'historylearningsite_co_uk-large-mobile-banner-1','ezslot_14',116,'0','0']));eval(ez_write_tag([[300,250],'historylearningsite_co_uk-large-mobile-banner-1','ezslot_15',116,'0','1'])); History Learning Site Copyright © 2000 - 2020. For the next two weeks all four divisions of the Canadian Corps took turns assaulting the Passchendaele ridge, making only meagre gains with heavy losses. The farthest objective was less than 1 mile (1.6 km) deep on September 20 and was reduced still more on the subsequent strokes. A discrepancy of, For British losses, Edmonds used data based on figures submitted by the Adjutant-General's Department to the Allied Supreme War Council on 25 February 1918; Edmonds also showed weekly returns to GHQ, giving a slightly lower total of, Orders of battle for the German attack on Vimy Ridge, German defensive preparations: June – July 1917, The British set-piece attack in late 1917, Official History of Australia in the War of 1914–1918, "Duke of Cambridge leads Commemorations on 100th Anniversary of the Battle of Passchendaele", "Battle of Passchendaele Centenary: Prince Charles Honours 'Courage and Bravery' of British Soldiers", "New Zealand Memorial (Gravenstafel ridge)", "Tribute to Scots Soldiers at Passchendaele", Passchendaele – Canada's Other Vimy Ridge, Norman Leach, Canadian Military Journal, Passchendaele, original reports from The Times, Armistice between Russia and the Central Powers, Deportations from East Prussia during World War I, https://en.wikipedia.org/w/index.php?title=Battle_of_Passchendaele&oldid=978871784, Battles of World War I involving Australia, Battles of World War I involving New Zealand, Battles of World War I involving South Africa, Battles of World War I involving the United Kingdom, Battles of the Western Front (World War I), Events of National Historic Significance (Canada), Creative Commons Attribution-ShareAlike License, This page was last edited on 17 September 2020, at 12:26.
