First Battle of Passchendaele
The First Battle of Passchendaele took place on 12 October 1917, in the Ypres Salient of the Western Front, west of Passchendaele village. The attack was part of the Third Battle of Ypres in the First World War. The British attacked to capture Passchendaele village, based on incorrect information that during the Battle of Poelcappelle (9 October), the attacking troops had captured the first objective line. The front line near Passchendaele had hardly changed after German counter-attacks in the afternoon recaptured most of the lost ground, which meant that the final objective for the attack on 12 October was 2,000–2,500-yard (1,800–2,300 m) forward, instead of the 1,500 yards (1,400 m) expected.
The main assault was conducted by the two Anzac corps in the Second Army against the German 4th Army, with a supporting attack by the Fifth Army between the northern boundary of the Second Army and the southern limit of the French First Army. The brigade attacks of the XVIII Corps in the Fifth Army area, managed to advance the front line on either side of the Ypres–Staden railway north of Poelcappelle but the Germans defeated the attacks by XIV Corps and retained control of the high ground on Passchendaele Ridge opposite the I and II Anzac corps, where the attack was repulsed or troops were forced later to retire from most captured ground, as had happened on 9 October. Further British attacks were postponed until the weather improved and communications behind the front could be restored. Two German divisions intended for Italy were diverted to Flanders, to replace "extraordinarily high" losses.[Note 1] The battle was a German defensive success but was costly for both sides.

In July 1917, Field Marshal Douglas Haig began the Third Battle of Ypres campaign, in an attempt to break out of the Ypres Salient. At the Battle of Messines the far side of the Messines Ridge had been captured down to the Oosttaverne Line and a substantial success gained in the subsequent Battle of Pilckem Ridge. At the Battle of Langemarck there was an advance of 1,500 yards (1,400 m) around Langemarck village by XIV Corps. In view of the failure of the British Fifth Army to advance on the Gheluvelt Plateau in August, Haig ordered that artillery reinforcements be added to the south-east along the higher ground of the Gheluvelt plateau, Broodseinde Ridge and the southern half of Passchendaele Ridge. The main offensive was switched to the British Second Army under command of General Herbert Plumer, who continued the evolution of bite-and-hold tactics that had been used in July and August.
The Second Army planned to attack with a succession of separate bodies of infantry, on narrower fronts, for about 800 yards (730 m) to the first objective, 500 yards (460 m) to the second objective and 300 yards (270 m) to the final objective. Pauses on successive objective lines would become longer and attacks would be protected by a bigger, deeper multi-layered creeping barrage. Standing barrages beyond the objective lines were to be fired during pauses for consolidation, to obstruct German counter-attacks into the captured area, which would be confronted by a series of defensive areas based on the British objective lines. The British infantry would be in communication with its artillery and have much more local support from the Royal Flying Corps (RFC). Beyond the "creeper", four heavy artillery counter-battery double groups, with 222 guns and howitzers, covered a 7,000-yard (6,400 m) front, ready to engage German guns with gas and high-explosive shell. Strictly limited advances using these methods, at the Battle of the Menin Road Ridge (20 September), Battle of Polygon Wood (26 September) and Battle of Broodseinde (4 October), had produced a 4,000-yard (3,700 m) advance in two weeks, inflicted many German casualties. The German high command had made several changes against the refined British attacking methods, all of which had failed.
In the lower ground west of the Passchendaele Ridge, three months of constant shelling had blocked the watercourses that normally provided drainage. On the night of 4 October, it began to rain and continued intermittently for the next three days. Much of the battlefield again became a quagmire, making movement extremely difficult. Had the German defence collapsed during the Battle of Poelcappelle on 9 October, the reserve brigades of II Anzac Corps were to have passed through later in the day, to continue the attack to the far side of Passchendaele village and the Goudberg spur to the north. On 7 October, this afternoon attack had been cancelled by Haig, because of the rain and the final details of the plan for the renewed attack of 12 October, were decided on the evening of 9 October. Plumer had received misleading information about the progress of the attack that day and believed that "a sufficiently good jumping-off line" had been achieved, passing the erroneous information back to Haig.[Note 2] The decision was made to continue the offensive, to gain more favourable winter positions on higher ground, to assist the French with their attack due on 23 October (the Battle of La Malmaison) and to hold German troops in Flanders during the preparations for the Battle of Cambrai.
British offensive preparations
Encouraged by the unusually high German losses during the Battle of Broodseinde and reports of lowered German morale, Haig sought quickly to renew the Allied offensive and secure Passchendaele Ridge. The Battle of Poelcappelle began on 9 October and was costly to both sides; most of the ground captured opposite Passchendaele was lost later in the day to German counter-attacks. News of this German defensive success was slow in reaching the higher British commanders, because the usual collapse of communications during an attack was exacerbated by the rain and mud. Late on 9 October, Plumer erroneously informed Haig that II Anzac Corps had reached the first objective, which made a good jumping-off position for the attack due on 12 October.[Note 3] Many British guns had sunk in the mud, bogged down while being moved forward or run short of ammunition. German artillery fire had become much heavier, as British counter-battery artillery fire by heavy artillery almost ceased from 9–12 October, as attempts were made to move the guns forward, although the defenders were still caused considerable difficulty by British bombardments.
The 3rd Australian Division and the New Zealand Division relieved the 66th Division and the 49th Division on the night of 10/11 October. Patrols discovered that the 49th Division had reached the Wallemolen spur east of the Ravebeek creek and found that the advance beyond had been stopped, by new barbed wire entanglements around the Flandern I line; the 66th Division on the right, was found to be back near its start line of 9 October. The New Zealand Division had to make hurried preparations behind the front line to restore communications and reconnoitre the ground, because the information available from the 49th Division headquarters was insufficient. Attempts were made to evacuate wounded but some were still stranded in no-man's-land, when the attack began on 12 October. Many field guns needed for the attack remained bogged in the mud and other field guns were placed on improvised platforms, when their new sites had proved impossible to reach, from which they fired slowly and inaccurately or sank into the mud. A German bombardment took place on the morning of 11 October and later in the day the British shelled the German defences on Wallemolen spur, to little effect. Some progress was made in the building of plank roads since the attack on 9 October and a few more guns had reached their new positions by 12 October. The Commander Royal Artillery of the New Zealand Division, reported that adequate artillery support for his division could not be guaranteed.
Plumer discovered that the line near Passchendaele had hardly changed and that the main reason for the failure on 9 October was uncut barbed wire 30 yards (27 m) deep, in front of the pillboxes at the hamlet of Bellevue on the Wallemolen spur. The New Zealand Division commander, Major-General Andrew Russell, later wrote that accurate information had arrived 24 hours too late to ask for a postponement or radically to alter the barrage plan and unit orders.[Note 4] The true position of the front line meant that the planned advance of 1,500 yards (1,400 m) to the final objective, would actually have to cover 2,000–2,500 yards (1,800–2,300 m). The opening barrage line planned for the 3rd Australian Division was moved back 350 yards (320 m) but this still required the infantry to advance for 500 yards (460 m) to reach it. Duckboard tracks had been extended to the line held on 9 October, which allowed infantry to move up on the night of 11 October in time for the attack, despite rain and a German gas bombardment on Gravenstafel spur. High winds and heavy rain began about zero hour (5:25 a.m.) and lasted all day.
Plan of attack
The II Anzac Corps and the Second Army headquarters were misinformed as to the extent of the advance achieved on 9 October. The objectives set for 12 October required an advance of 2,000–2,500 yards (1,800–2,300 m) to the final objective, rather than the intended 1,000–1,500 yards (910–1,370 m). The I Anzac Corps with the 4th and 5th Australian divisions, in place of the exhausted 1st and 2nd Australian divisions, was to provide a flank guard to the south. The I Anzac Corps was to advance across the Keiberg Spur and dig in on the flank of the main assault, at the first and second objective lines only, 1,200 yards (1,100 m) and 880 yards (800 m) forward.
The main attack was to be undertaken by the Second Army, with the 3rd Australian Division and the New Zealand Division of the II Anzac Corps, on a front of 3,000 yards (2,700 m). The 3rd Australian Division would attack Passchendaele ridge and the village and the New Zealand Division was to capture the Bellevue Spur. The first objective (Red Line) was practically the same as the second objective of the attack on 9 October, 1,200 yards (1,100 m) forward, beyond the Bellevue pillboxes. The second objective (Blue Line) was 880 yards (800 m) beyond, at the junction of the Wallemolen Spur and was the jumping-off line for the attack on the village of Passchendaele. The final objective (Green Line) lay 400 yards (370 m) beyond the village.
Although short of fresh troops, the Fifth Army was to establish the northern flank of the main attack. In the XVIII Corps area, the 26th Brigade of the 9th Division was to advance 2,000 yards (1,800 m) to the ridge north of the Goudberg re-entrant and the 55th Brigade of the 18th Division was to attack for a similar distance north of the Lekkerboterbeek creek. In the XIV Corps area, the 12th Brigade of the 4th Division, the 51st Brigade of the 17th Division and the 3rd Guards Brigade of the Guards Division, were to advance beyond Poelcappelle and close up to Houthoulst Forest, on the boundary with the French First Army.
In the New Zealand Division sector, the two attacking brigades each had a machine-gun company and three other machine-gun companies were to fire a machine-gun barrage. The division had the nominal support of one-hundred and forty-four 18-pounder field guns and forty-eight 4.5 inch howitzers The artillery was expected to move forward after the final objective was gained, to bombard German-held ground from positions 1,000–2,000 yards (910–1,830 m) beyond Passchendaele village. On the southern flank, the I Anzac Corps was to capture ground south of the Ypres–Roulers railway along with attacks by X Corps and IX Corps.
German defensive preparations
After their defensive success on 9 October, the Germans brought fresh divisions into the line but the tempo of British operations caused considerable anxiety among German commanders. The 18th Division took over in the Poelcappelle area; on a 1,000-metre (1,100 yd) front, the division had 17 heavy machine-guns and large numbers of MG 08/15 machine-guns distributed among its infantry companies. Ludendorff's defensive changes had been implemented in some parts of the front, despite a certain reluctance among some of the local commanders. Outposts beyond the German advanced defensive zone (Vorfeld) were to hold the front line in enough strength to stop the British from sapping forward. The garrisons were to withdraw to the main line at the rear of the Vorfeld when attacked, signalling to the artillery with rockets and Very lights for barrage fire. The German artillery would place the barrage in front of the main line of resistance, before the British infantry reached it and if possible, the troops in the front position were to attempt to defeat the attack without calling on the supporting Eingreif division, to limit casualties.
In his diary, Rupprecht wrote that he was doubtful about the changes of tactics required by Ludendorff, especially his instructions for more counter-battery fire, since in previous battles, the German artillery had engaged British infantry. An anticipated French attack on the Chemin des Dames, meant that fewer reinforcements could be expected by the Fourth Army, making a fighting withdrawal the only possible response to the British attacks. Rupprecht wrote that the fighting power of German troops in Flanders was declining and that all attempts to counter the British artillery had failed, requiring a greater retreat, far enough back to force the British into a laborious artillery redeployment. After being postponed from 2 October, due to delays in the transport of ammunition, Operation Mondnacht took place at midnight on 11/12 October. A strip of ground from Messines to Dixmude was bombarded with gas, which high winds dispersed with little effect on Allied troops.
The main attack in the vicinity of Passchendaele was conducted by the two Anzac corps of the Second Army. Rain fell all night on 11/12 October, with only one dry interval during the day. The Germans opposite the New Zealanders had been alert all night, sending up many flares and conducting an artillery bombardment on the New Zealand front line at 5:00 a.m., which hit the New Zealand trench mortar personnel and destroyed their ammunition.[Note 5] The 12th Brigade of the 4th Australian Division, advanced on time at 5:25 a.m. but saw no infantry from the 3rd Australian Division beyond the railway. The brigade captured the Keiberg cutting and consolidated, along with the rest of the first objective, although with many casualties. The 9th Brigade of the 3rd Australian Division, managed to reach the first objective and the battalion due to advance to the second objective went straight on. As soon as those troops began to descend from a slight rise, they were engaged by German field and heavy artillery. The brigade kept going to the second objective, although part of the advance remained bogged down short of the first objective. The 10th Brigade of the 3rd Australian Division, suffered many losses from machine-guns in pillboxes. The brigade reached a fold in the ground near the first objective which gave some cover, despite increasing machine-gun fire from the Bellevue pillboxes in the New Zealand Division area.
The New Zealand advance was obstructed by uncut barbed wire on the Wallemolen spur; the creeping barrage was very thin, as some guns were bogged and others had been knocked out by German artillery. The creeping barrage diminished as it moved forward and howitzer shells, plunging into wet ground around the Bellevue pillboxes exploded harmlessly. The German artillery fired all the way to the rear of the New Zealand divisional area and machine-gun barrages from the German pillboxes raked the advance. The division captured the cemetery at Wallemolen and reached Wolf Copse, the right of the advance stopping on the rise astride the Ravebeek creek. North of the Gravenstafel–Metcheele road, the division gained some ground but was stopped by belts of barbed wire 25–50 yards (23–46 m) deep and were swept by machine-gun fire. The infantry tried to cut their way through the wire of the German Flandern I defensive line on the Wallemolen spur and small numbers of troops got through both belts but were killed after being stopped by more wire around the German pillboxes. Further south, the New Zealand Division captured two pillboxes, with help from 3rd Australian Division troops in the area. An advance began up the northern slope of the Ravebeek creek but broke down quickly around Laamkeek. At 8:00 a.m. the surviving New Zealand infantry were ordered to dig-in.
The advance of the Australians towards the second objective began at 8:25 a.m. but the 10th Brigade had suffered too many casualties to advance and dug-in to wait for reinforcements. One party from the 10th Brigade kept going and arrived at the pillbox near Crest Farm, whose occupants promptly surrendered. The party then advanced into Passchendaele village, before German troops rallied and re-occupied the pillbox. Small groups from the 12th Brigade got across the Keiberg spur with many losses. The 12th Brigade repulsed two German counter-attacks between 3:00 p.m. and 4.00 p.m. An attempt was made to use the reserve battalion of the 9th Brigade to outflank the Bellevue pillboxes, combined with a new attack by the New Zealand Division around 3:00 p.m. The attack was eventually cancelled, as the 9th Division to the north and the 3rd Australian Division to the south were forced back by the fire of the Bellevue machine-guns. The artillery bombardment went ahead, dropping on some New Zealand positions but also dispersing two German parties massing for a counter-attack. By 3:30 p.m. the 10th Brigade had filtered back to its start-line, due to fire from the Bellevue Spur. The 9th Brigade was exposed by this retirement and fell back from the second objective in the face of artillery, machine-gun and sniper fire, with many losses. When the Anzac advance broke into the front between Passchendaele and the Keiberg Spur, I Battalion, Reserve Infantry Regiment 55 of the 220th Division was attached to the 195th Division, and II Battalion, Reserve Infantry Regiment 55 to the 233rd Division, which with the divisions in the line, reoccupied the areas vacated by the Australians and New Zealanders, capturing 56 unwounded and many wounded Australians. In the evening most of the New Zealand Division withdrew to a line on the lower slopes of the Wallemolen spur.
Protection of the northern flank of the main attack by the Second Army was provided by the Fifth Army, with single brigades of the 9th and 18th divisions of XVIII Corps, attacking from north of Goudberg to north of the Lekkerboterbeek stream adjacent to the northern boundary of the Second Army. The 26th Brigade of the 9th Division was to advance 2,000 yards (1,800 m) on a 1,500-yard (1,400 m) front, with its left flank on the Lekkerboterbeek, into an area dotted with fortified farm buildings. The 55th Brigade of the 18th Division attacked north of the Lekkerboterbeek, over ground soaked after rain all day on 11 October. A low-flying German aircraft had reconnoitred the area near the 55th Brigade so the position of the jumping-off line was altered, to avoid a possible German counter-barrage as the brigade formed up for the advance.
The 9th Division was hampered by the effect of rain and mud on supply routes, which stranded guns and caused shortages of ammunition, particularly in smoke shells. At midnight on 11 October, torrential rain fell and a German gas and high explosive bombardment fell on the divisional forming-up areas. The wide front left numerous gaps in the line, as the 26th Brigade advanced behind a barrage moving at 100 yards (91 m) in eight minutes, assisted by a machine-gun barrage from 16 Vickers machine guns. The creeping barrage began at 5:35 a.m. and was described as "thin and ragged". The advancing troops lost direction and communication broke down, as carrier pigeons were hindered by the high wind and messenger dog handlers became casualties. The infantry continued their advance and on the right of the captured Adler Farm and reached the green line at Source Trench.
In the centre, the attackers had to dig in after a 100 yards (91 m) advance. Small parties reached Source Trench and some may have advanced as far as Vat Cottages. On the left of the brigade, the ground was even worse, the infantry were unable to keep up with the barrage and became lost but managed to capture a pillbox and move forward. Some of the troops on the left flank inadvertently crossed the Lekkerboterbeek, advanced 80 yards (73 m) and then formed a flank with troops from the 18th Division. Except on the right flank, the attack was stopped by the Germans only 100 yards (91 m) from the start line, despite the 27th Brigade being sent to reinforce the attack, in which some of the British infantry drowned in shell-holes. The new front line ran from the junction with the New Zealand Division at the cemetery near Wallemolen, to Oxford Houses then back to the old front line.
The barrage began at 5:20 a.m. and the 18th Division infantry advanced in "snake formation". The divisional field artillery suffered the same fate as those of the divisions to the south, many guns sinking into the soft ground. A German counter-barrage began within a minute of the advance and as British troops took cover, German machine-gunners fired at the crater lips of shell-holes, through which bullets penetrated and hit the soldiers sheltering inside. The effect of the German barrage was worst on the right flank and added to German machine-gun fire from the Brewery and Helles House strong points; the situation at Requette Farm was not known as all runners sent from the area were killed. Mud clogged weapons of all types and at 11:00 a.m., a British trench-mortar battery and some supporting machine-guns had to cease fire, because of wet and dirty ammunition. At noon, German counter-attacks towards the west end of Poelcappelle began and lasted all afternoon, the Germans trying to exploit a gap between the British 4th and 18th divisions. Defensive positions in shell-holes were held by the survivors of the British attack.
The northern flank of the Fifth Army, on the boundary with the French First Army, was held by XIV Corps, which also attacked with a brigade of each division to close up to Houthoulst Forest. After dark on 11 October, tape was laid beyond the front line in the corps area, for the troops to form up on, beyond a possible German counter-barrage. To avoid detection, scouts patrolled further forward, to ambush German patrols. The 3rd Guards Brigade of the Guards Division moved up on the night of 11 October, through heavy rain and a German gas barrage (Operation Mondnacht), which caused many casualties in this part of the front. The artillery barrage began on schedule at 5:25 a.m. and the German counter-barrage was slow to begin, falling mostly behind the attacking waves. The XIV Corps divisions had much better artillery and machine-gun barrages than the divisions further south and the creeping barrage moved at a very slow rate of 100 yards (91 m) in ten minutes, in two 300-yard (270 m) bounds.
The 12th Brigade headquarters of the 4th Division next to the XVIII Corps area, was to attack with a composite force of two battalions of the 10th Brigade and two from the 12th Brigade. Two battalions were to lead, with a battalion each in support and reserve, following on to a first objective about 200 yards (180 m) forward and then pivot on the right to the final objective, another 300 yards (270 m) forward on the left at Water House. The ground had been soaked again by overnight rain and the advance by the right-hand battalion was stopped at Requette Farm, by determined German resistance and massed machine-gun fire, during which contact with the neighbouring 18th Division battalion was lost. The left-hand battalion advance faced less opposition and by 6:20 a.m. had crossed the Poelcappelle–le 5 Chemins road, captured Memling Farm and Senegal Farm and then made contact with the 17th Division. After the capture of Requette Farm by the right-hand battalion, more German machine-gun fire was received from the Brewery and Helles House, which stopped the attack on the right flank. Requette Farm was lost to a German counter-attack around noon and attempts by reinforcements to re-take the farm were abandoned as dark fell. The brigade extended a defensive flank on the right, to maintain contact with the 18th Division. The new front line curved back through Besace Farm to west of Helles House, south-west of Requette Farm, north of Poelcappelle.
The 51st Brigade of the 17th Division was to advance for 1,600 yards (1,500 m) astride the Ypres–Staden railway, to meet the left flank of the 4th Division north of Poelcappelle and the right flank of the Guards Division, 400 yards (370 m) north of the railway. Beyond the railway, the advance of the 51st Brigade veered slightly south, away from a German strong-point which caused many casualties, losing lost touch with the Guards Division. South of the embankment, astride the Broombeek and Watervlietbeek streams, several German farm strong-points, pillboxes and shell-hole positions were overrun by the infantry, who were able to keep well up to the very-slow-moving barrage. The brigade reached its first objective by 8:00 a.m., despite a number of German reinforcements arriving through the British artillery barrages. The final objective was reached at 11:00 a.m. and on the right a defensive flank was thrown back from Memling Farm at the final objective, to meet troops of the 4th Division. By noon the advance was complete, 218 German prisoners had been taken and no German counter-attack followed, resistance being limited to a small amount of rifle fire.
In cold, wet weather, the 3rd Guards Brigade made a short advance behind a ragged barrage, took the higher ground on the edge of Houthoulst Forest and cut off the rest of the spur running north-east from Veldhoek. Contact with the 17th Division on the right flank was lost, after the left flank formation of the 17th Division veered south and the crew of a contact patrol aircraft observing the advance, failed to see the loss of direction. Two platoons detailed to meet the attacking brigade of the 17th Division, had to dig in near the Angle Point pillbox under machine-gun fire. After dark, the Guards and the 17th Division closed the gap, by capturing the blockhouses at Angle Point and Aden House. Next day, conditions were so bad that the attacking brigade was relieved by the 1st Guards Brigade. The fresh troops patrolled vigorously to the southern edge of Houthoulst Forest, against little organised German resistance, except for extensive sniping around the Colbert cross-roads and Colombo House.
During the battle, forty-one British pilots made low-altitude strafing and bomb attacks. The British flew an additional 27 contact and counter-attack patrols and 124 zone-calls were made to the artillery, to engage German machine-gun nests, troops, artillery and transport. British aircraft observers made 26 calls to destroy German artillery batteries and an additional 37 calls for artillery battery neutralisation. The British flew four bombing raids on German encampments and railway stations, eight reconnaissance flights beyond the battlefront and engaged in twelve dogfights with German aircraft. The British squadrons lost fourteen aircraft; five crew members returned wounded.[Note 6]
The German defence on 12 October was more effective than expected. The German 18th Division held the line opposite Poelcappelle and retained most of its area after committing all of its reserves. The German command considered that the Allied advance in the north to be less dangerous than that towards the Flandern II defensive line, between Passchendaele and Drogenbroodhoek. One division was moved to Morslede and another to the area between Westrozebeke and Stadenberg, either side of Passchendaele. The 195th Division at Passchendaele had so many casualties (3,325) from 9–12 October, that it had to be relieved by the 238th Division. Ludendorff changed his mind about the prospect of retaining Passchendaele Ridge, believing that the British had only fourteen days before the weather made attacks impossible and ordered Rupprecht to stand fast. At a conference on 18 October, Hermann von Kuhl advocated a retreat as far to the east as possible; Sixt von Armin the Fourth Army commander and his chief of staff, Colonel Fritz von Lossberg preferred to fight to hold their remaining defences in Flandern I and Flandern II, because the ground beyond the Passchendaele watershed was untenable, even in winter.
The British attack was costly for both sides, captured more ground opposite Passchendaele than the attack of 9 October and the British took more than 1,000 prisoners. British artillery support was inadequate, due the amount of field artillery out of action and the vast increase in mud, which smothered high-explosive shell-detonations. The weather from 4–12 October also prevented counter-battery fire and little was achieved by the heavier guns. On 13 October, the British decided to stop the offensive until better weather returned and roads and tracks had been repaired, to ensure that deliberate attacks with a greater quantity of artillery support could be resumed. Operations were to continue to reach a suitable line for the winter and to keep German attention on Flanders, to help the French attack due on 23 October and the Third Army operation south of Arras due in mid-November (the Battle of Cambrai). The Canadian Corps relieved the II Anzac Corps on 18 October, in the depression between Gravenstafel Ridge and the heights at Passchendaele. The captured ground made a slightly better starting line for the Second Battle of Passchendaele, which began on 26 October.
Casualties and commemoration
Ludendorff divided the Third Battle of Ypres into five periods. In the Fourth Battle of Flanders, from 2–21 October, he described German casualties as "extraordinarily high". Hindenburg wrote later that he waited with great anxiety for the wet season. In Der Weltkrieg (1942), the German Official Historians recorded 12,000 casualties, including 2,000 missing for the accounting period 11–20 October but did not give a separate figure for 12 October. The 4th Australian Division suffered c. 1,000 casualties and the 3rd Australian Division c. 3,199 casualties. From 9–12 October, the German 195th Division lost 3,395 casualties. There were 2,735 New Zealand casualties, 845 of whom were killed or mortally wounded and stranded in no man's land. In 2007 Harper wrote that 846 New Zealanders were killed, 2,000 were wounded and 138 men died of their wounds in the following week. The 4th Division lost 3,569 casualties from 4–12 October. Calculations of German losses by J. E. Edmonds, the British Official Historian, have been severely criticised, for adding 30% to German casualty figures, to account for different methods of calculation. The New Zealand Memorial to the Missing at Tyne Cot, commemorates New Zealanders killed during the Battle of Broodseinde and the First Battle of Passchendaele, who have no known grave and the Buttes New Zealand Memorial contains the mortal remains of New Zealand troops killed from September 1917 until February 1918. In 1997, Christopher Pugsley wrote that the casualties made 12 October 1917 New Zealand's blackest day and in 2007, Glyn Harper wrote that ".... more New Zealanders were killed or maimed in these few short hours than on any other day in the nation's history".

On 14 October a German attack captured a post on the IX Corps front in the 37th Division area. Next day patrols from the 9th Division (XVIII Corps) found Varlet Farm occupied. After a 48-hour bombardment, an attack at 5:25 a.m. on 20 October, by two battalions of the 18th Division reached a German headquarters west of Poelcappelle church. On 21 October, wire-cutting began on the Fifth and Second Army fronts; under cover of the bombardment, 18th Division platoons moved forward on the night of 21 October and dug shallow trenches, which saved many casualties from a German counter-bombardment, after a ruined farm behind the jumping-off places caught fire and silhouetted the troops during a gas bombardment. On 22 October, in the British 9th Division sector to the south, the XVIII Corps Cyclist Battalion conducted a feint, using dummy figures to assist an attack by the 9th Division, which captured the Brewery strong-point quickly. The attack was resumed at 7:30 a.m. through the village, taking Noble's Farm, Meunier House and then Tracas Farm, a total advance of 1,000 yards (910 m). At 5:00 p.m. a German counter-attack was stopped short of Noble's Farm with many casualties. In the XIV Corps area, two brigades of the 34th Division attacked at 5:35 a.m., the right-hand brigade taking their objectives and also Requette Farm in the 18th Division area. The left brigade advanced until close to a row of pillboxes, which were thought to have been captured and was cut down. Reinforcements were stopped at the Broombeek due to flooding and a heavy German barrage.
Next to the 35th Division the attack reached Six Roads, where covering fire was used as the troops to the right tried to outflank the pillboxes but uncut wire stopped the attack; a counter-attack then forced them back to the east of Egypt House. A two-brigade attack by the 35th Division was made at the same time. The right brigade reached the first objective easily, then the advance was stopped by machine-gun fire. Further to the left Colombo House was captured, the final objective on Conter Drive was reached at 6:45 a.m. and some ground beyond Angle Point and Aden House was then captured. The left brigade captured Marechal Farm on its right flank but the attack in the centre was stopped by machine-gun fire, 500 yards (460 m) north west of Colombo House. On the left Panama House was captured and the final objective reached by 7:45 a.m. A German counter-attack forced a retreat to the start line by one battalion but was then caught by British artillery fire and forced under cover. On 21 October German positions from the Corverbeek to the Wallemolen Spur had been subjected to an intense bombardment of high-explosive, shrapnel and gas shell. A regiment of the French 1st Division prepared to attack on a 1,100-yard (1,000 m) front, as the Fifth Army on the right prepared for the main part of the operation. The evening was dry until after midnight, when it began to rain and a thick mist rose and it became impossible to see more than a few yards by the time the advance began just before 6:00 a.m. on 22 October. Despite a drying wind for several days, the ground in most places was a morass.
The German 40th Division and elements of the 58th Division held the line opposite the French north of Mangelaere, where the French 1st Division had to capture a number of redoubts and the ruins of Jean Bart Farm. The preliminary French artillery bombardment was so effective, that the French objectives were quickly taken and the French joined in the attack east of Veldhoek, where they helped the British to reduce a number of pillboxes. Some resistance was encountered at Panama Farm, north-east of Veldhoek, which was soon overcome and with few casualties the French, often up to their waists in water, reached the fringes of Houthulst Forest, 1,100 yards (1,000 m) from the jumping-off point and captured two field guns and several prisoners. On the evening of 23 October, the seventh German counter-attack since the operation began was made at the junction of the French and British armies and was a costly failure, as was another counter-attack on the evening of 24 October, at the southern outskirts of Houthulst Forest. In the operations at Poelcappelle by the 18th and 34th divisions and at Houthoulst Forest by the British 35th and French 1st Division, 125 prisoners were taken and the Fifth Army had 479 casualties.
- In the worst weather conditions of the campaign, which occurred in the five weeks after the Battle of Broodseinde, the number of troops engaged by the British amounted to no more than those involved in the Battle of Pilckem Ridge on 31 July. On 26 October, 34 battalions took part in the attack, on 30 October, 12 1⁄4 battalions, on 6 November 10 battalions, on 10 November 11 battalions, on 2 December 10 battalions and the New Zealand attack on Polderhoek Château during 3 December, was made by two battalions. British losses in October 1917 were the third highest of the war, after July 1916 and April 1917.
- According to J. E. Edmonds, the British Official Historian, on 7 October, Gough and Plumer told Haig that they favoured ending the campaign, because of the return of poor weather and general state of the battlefield. Prior and Wilson wrote that this meeting did not appear in contemporary records and doubted that it took place.
- C. E. W. Bean, the Australian Official Historian, held the II Anzac Corps commander Godley and his staff responsible for failing to find out the true state of events, despite there being time to do this before the coming attack.
- In 1941 the Australian Official Historian Charles Bean, attributed the delay to inefficiency by Lieutenant-General Alexander Godley, the II Anzac Corps commander and his staff, as did Pugsley in 1997.
- British Expeditionary Force time went back one hour to Greenwich Mean Time on 8 October, the attack beginning at 6.25 a.m. British Summer Time. The progression of the season can be seen in the changes of zero hour relative to British Summer Time. Messines, 7 June 3:10 a.m., Pilckem Ridge, 31 July 3:50 a.m., Gheluvelt Plateau, 10 August 4:35 a.m., Langemark, 16 August 4:45 a.m., Menin Road, 20 September 5:40 a.m., Polygon Wood, 26 September 5:50 a.m., Broodseinde, 4 October 6:00 a.m., Poelcappelle, 9 October 6:20 a.m. and First Passchendaele, 12 October 6:25 a.m.
- Zones were based on lettered squares of the army 1:40,000 map; each map square was divided into four sections 3,000 square yards (2,500 m2). The observer used a call-sign of the map square letter then the zone letter to signal to the artillery. All guns and howitzers up to 6 inches (150 mm) able to bear on the target, opened rapid fire using corrections of aim from the air observer.
