The increased amount of heavy artillery was to be used to destroy German concrete shelters and machine-gun nests, which were more numerous in German "battle zones", than the "outpost zones" which had been captured in July and August and to engage in more counter-battery fire. Few German concrete pill-boxes and machine gun nests had been destroyed during earlier preparatory bombardments and attempts at precision bombardment between attacks had also failed. The 112 heavy and 210 field guns and howitzers in the Second Army on 31 July, were increased to 575 heavy and medium and 720 field guns and howitzers for the battle, which was equivalent to one artillery piece for every 5 ft (1.5 m) of the attack front and more than double the density in the Battle of Pilckem Ridge. Plumer's tactical refinements sought to undermine the German defence by making a shallower penetration and then fighting the principal battle against German counter-attack (Eingreif) divisions. By further reorganising infantry reserves, Plumer ensured that the depth of the attacking divisions roughly corresponded to the depth of local German counter-attack reserves and their Eingreif divisions. More infantry was provided for the later stages of the advance, to defeat German counter-attacks, by advancing no more than 1,500 yd (1,400 m) before consolidating their position. When the Germans counter-attacked they would encounter a British defence-in-depth, protected by artillery and suffer heavy casualties to little effect, rather than the small and disorganised groups of British infantry that the Germans had driven back to the black line on the XIX Corps front on 31 July. Minor operations During a lull in early September, both sides tried to improve their positions; on 1 September, a determined German attack at Inverness Copse was repulsed. Further north in the XIX Corps area, a battalion of the 61st Division rushed Hill 35 but only took a small area; another attempt on 3 September failed.

After dawn, aerodromes were periodically to be attacked by small formations of low-flying fighters and by day bombers from high-altitude. German defensive preparations Main article: German defensive preparations: June–July 1917 From mid-1917, the area east of Ypres was defended by six German defensive positions the front position, Albrechtstellung (second position), Wilhemstellung (third position), Flandern I Stellung (fourth position), Flandern II Stellung (fifth position) and Flandern III Stellung (under construction). Between the German defence positions, lay the Belgian villages of Zonnebeke and Passchendaele. "Elastic" defence tactics had been rejected by the 4th Army Chief of Staff, Major-General Fritz von Loßberg, who believed that a tactical withdrawal by trench garrisons would disorganise the counter-attacking reserves, leading to the loss of the sector and danger to flanking units. Loßberg ordered the front line of sentry groups (Postengraben) to be held rigidly; British attacks would exhaust themselves and then be repulsed by local German reserves or by Eingreif divisions. Loßberg also judged that there was little prospect of British attacks being delayed by their need to move artillery forward and build supply routes. The British had a huge mass of artillery and the infrastructure necessary to supply it with ammunition, much of it built opposite the Flandern I Stellung in the period between the attack at Messines and 31 July. German defensive tactics had been costly but succeeded on the front of XIX Corps on 31 July and against II Corps on the Gheluvelt Plateau on 31 July and during August, although the counter-attacks had been stopped in their turn by British artillery fire, when they reached areas where observation and communications between British infantry and artillery had been restored. Ludendorff later wrote that losses in the August battles had been unexpectedly high. The pause in British operations in early September helped to mislead the Germans. General von Kuhl (Chief of Staff, Army Group Crown Prince Rupprecht) doubted that the offensive had ended but by 13 September had changed his mind.

The 39th Division crossed the German trenches in front of La Targette, where two strong points contained artillery but the French advance was so swift, that only a few machine-gunners were able to engage them and the village was captured by 11:15 a.m., 350 prisoners being taken. The area was quickly consolidated and French field artillery galloped up to engage German troops nearby. The French pressed on to Neuville and advanced up the southern part of Vimy Ridge but troops of the 11th Division on the right flank, were held up by the defenders of the Labyrnthe. In the centre, the French gained a foothold in houses at the south end of the village and near the cemetery and half of the village was captured. On the main front, the French artillery had prepared the way for the infantry and creeping barrages had kept the surviving German infantry pinned down but where the French had fewer heavy guns and ammunition, the attacks had failed. The XVII Corps to the south of the attack front, had been expected to make a deeper advance than the other corps but was stopped by German machine-gun fire in no man's land and was only able to establish small footholds in the first position. In the south of the attack front, the X Corps infantry were stopped in no man's land. By nightfall the Tenth Army had taken 3,000 prisoners, ten field guns and fifty machine-guns. The success of XXXIII Corps had used up much of its ammunition and poor-quality shells had caused 24 premature explosions in its guns, against only four knocked out by German counter-battery fire. On 10 May, Joffre and Foch decided that infantry attacks would have to reflect the capacity of the artillery to support them and a proposal by d'Urbal to attack south of Arras was rejected. Joffre ordered several cavalry divisions to move towards the Tenth Army area as a decoy. To keep German reserves pinned down, a feint attack was made north of the Lorette Spur towards Loos, which managed a small advance on the left, until stopped by the fire of German artillery in Angres. On the Lorette Spur, machine-gun fire from a German strong point near the chapel caused many French casualties. A counter-attack from the sugar refinery between Ablain and Souchez was seen assembling and the French attack in the area was suspended. Barrage fire by the French artillery prevented the German infantry from advancing and the French infantry descended from the spur towards the Ablain ravine. The attack on Carency continued and German counter-attacks recovered some of the communication trenches and tunnels connecting it with Souchez. During the day, houses east of the village were stormed and a hollow south of the Carency–Souchez road was captured.

Divisional artillery commanders asked for two aircraft per division, exclusively to conduct counter-attack patrols. With observation from higher ground to the east, German artillery fire inflicted many casualties on the British troops holding the new line beyond Langemarck. The success of the German 4th Army in preventing the Fifth Army from advancing far along the Gheluvelt Plateau, led Haig to reinforce the offensive in the south-east, along the southern side of Passchendaele Ridge. Haig gave principal authority for the offensive to the Second Army (General Herbert Plumer) on 25 August. Like Gough after 31 July, Plumer planned to launch a series of attacks with even more limited geographical objectives, using the extra heavy artillery brought in from the armies further south to deepen and increase the weight of the creeping barrage. Plumer intended to ensure that the infantry were organised on tactically advantageous ground and in contact with their artillery, when they received German counter-attacks. Minor operations by both sides continued in September along the Second and Fifth army fronts, the boundary of which had been moved northwards, close to the Ypres–Roulers railway at the end of August. Casualties The Official Historian J. E. Edmonds recorded British casualties for 31 July – 28 August as 68,010, of whom 10,266 had been killed, with a claim that 37 German divisions had been exhausted and withdrawn. Calculations of German losses by Edmonds have been severely criticised ever since. By mid-August the German army had mixed views on the course of events. The defensive successes were a source of satisfaction but the cost in casualties was unsustainable. The German Official History recorded the loss of 24,000 casualties from 11–21 August, including 5,000 missing, 2,100 prisoners and c. 30 guns. Rain, huge artillery bombardments and British air attacks, greatly strained the fighting power of the remaining German troops. In 1931, Gough wrote that 2,087 prisoners and eight guns had been captured.

British artillery fired a preparatory bombardment from Polygon Wood to Langemarck but the German guns concentrated on the Gheluvelt Plateau. The British artillery was hampered by low cloud and rain, which made air observation extremely difficult and shells were wasted on empty gun emplacements. The British 25th Division, 18th Division and the German 54th Division took over by 4 August but the German 52nd Reserve Division was not relieved; both sides was exhausted by 10 August. The 18th Division attacked on the right and some troops quickly reached their objectives but German artillery isolated the infantry around Inverness Copse and Glencorse Wood. German troops counter-attacked several times and by nightfall the copse and all but the north-west corner of Glencorse Wood had been recaptured. The 25th Division on the left flank advanced quickly and reached its objectives by 5:30 a.m., rushing the Germans in Westhoek but snipers and attacks by German aircraft caused an increasing number of casualties. The Germans counter-attacked into the night as the British artillery bombarded German troops in their assembly positions. The appalling weather and costly defeats began a slump in British infantry morale; lack of replacements concerned the German commanders. Plan of attack Ypres area, 1917 The attack was planned as an advance in stages, to keep the infantry well under the protection of the field artillery. II Corps was to reach the green line of 31 July, an advance of about 1,480–1,640 yd (1,350–1,500 m) and form a defensive flank from Stirling Castle to Black Watch Corner. The deeper objective was compensated for by reducing battalion frontages from 383–246 yd (350–225 m) and leap-frogging supporting battalions through an intermediate line, to take the final objective. On the 56th Division front, the final objective was about 550 yd (500 m) into Polygon Wood. On the right, the 53rd brigade was to advance from Stirling Castle, through Inverness Copse to Black Watch Corner, at the south western corner of Polygon Wood, to form a defensive flank to the south.

Casualties in the 33rd Division were so great that it was relieved on 27 September by the 23rd Division, which had only been withdrawn on the night of 24/25 September. Battle of Polygon Wood　ポリゴンの森の戦い Australian infantry with small box respirator gas masks, Ypres, September 1917 The Second Army altered its Corps frontages soon after the attack of 20 September, for the next effort (26 September – 3 October) so that each attacking division could be concentrated on a 1,000 yards (910 m) front. Roads and light railways were extended to the new front line, to allow artillery and ammunition to be moved forward. The artillery of VIII Corps and IX Corps on the southern flank, simulated preparations for attacks on Zandvoorde and Warneton. At 5.50 a.m. on 26 September, five layers of barrage fired by British artillery and machine-guns began. Dust and smoke thickened the morning mist and the infantry advanced using compass bearings. Each of the three German ground-holding divisions attacked on 26 September, had an Eingreif division in support, twice the ratio of 20 September. No ground captured by the British was lost and German counter-attacks managed only to reach ground to which survivors of the front-line divisions had retired. Battle of Broodseinde ブルードサインデの戦い The Battle of Broodseinde (4 October), was the last assault launched by Plumer in good weather. The operation aimed to complete the capture of the Gheluvelt Plateau and occupy Broodseinde Ridge. The Germans sought to recapture their defences around Zonnebeke, with a methodical counter-attack also to begin on 4 October. The British attacked along a 14,000 yards (13,000 m) front and by coincidence, Australian troops from I Anzac Corps met attacking troops from the German 45th Reserve Division in no man's land when Operation Hohensturm commenced simultaneously. The Germans had reinforced their front line to delay the British capture of their forward positions, until Eingreif divisions could intervene, which put more German troops into the area most vulnerable to British artillery. The British inflicted devastating casualties on the 4th Army divisions opposite.

The Battle of Polygon Wood took place during the second phase of the Third Battle of Ypres in World War I and was fought near Ypres in Belgium 26 September – 3 October 1917, in the area from the Menin Road to Polygon Wood and thence north, to the area beyond St Julien. Much of the woodland had been destroyed by the huge quantity of shellfire from both sides since 16 July and the area had changed hands several times. General Herbert Plumer continued the series of British general attacks with limited objectives. The British attacks were led by lines of skirmishers, followed by small infantry columns organised in depth, (a formation which had been adopted by the Fifth Army in August) with a vastly increased amount of artillery support, the infantry advancing behind five layers of creeping bombardment on the Second Army front. The advance was planned to cover 1,000–1,500 yd (910–1,370 m) and stop on reverse slopes which were easier to defend, enclosing ground which gave observation of German reinforcement routes and counter-attack assembly areas. Preparations were then made swiftly to defeat German counter-attacks, by mopping-up and consolidating the captured ground with defences in depth. The attack inflicted a severe blow on the German 4th Army, causing many losses, capturing a significant portion of the Flandern I Stellung, which threatened the German hold on Broodseinde ridge. The better weather continued to benefit the British attackers by drying the ground, raising mist which obscured British infantry attacks made around dawn, then clearing to reveal German Eingreif formations to air and ground observation, well in advance of their arrival on the battlefield. German defensive arrangements were changed hastily after the battle to try to counter British offensive superiority. The Battle of Polygon Wood ポリゴンの森の戦い

Visibility early on 16 June was poor and the French heavy artillery began with a slow bombardment until 12:15 p.m., when a creeping barrage began to move from the French front line in 55 yd (50 m) bounds and a second barrage began at maximum range and crept backwards in 27 yd (25 m) bounds, until both barrages coincided on Vimy Ridge and became a standing barrage until the French infantry arrived. The IX Corps divisions found that the German defences were intact, when the attack began and the 17th Division was swept by artillery and machine-gun fire, forcing it back to its jumping-off trenches; the 18th Division managed to capture the German first position and a second attack was ordered for the afternoon. IX, XX and XXXIII corps used 10,000 shells, which contained poison gas and incendiary material on Neuville, Souchez and Angres, German artillery positions at ferme La Folie and rear areas. The shells were filled with carbon disulphide and phosphorus, which gave a combined asphyxiating and incendiary effect. The gas shells suppressed the German artillery opposite from 1:00–2:30 p.m. and set many fires in Angres but not at Souchez, which had been bombarded so much that there was little combustible material left. The 17th Division managed to advance another 110 yd (100 m) and the 18th Division was stopped in no man's land. On the right flank the 39th Division of XX Corps was repulsed in the first attack, despite creeping forward before zero hour, to be clear of a German counter-bombardment and to catch the German infantry under cover. The division prepared a new bombardment for 3:20 p.m. on the German front line, to at least advance across no man's land. The new attack also failed, as did the attacks of the 17th and 11th divisions on either flank.[60]In the XXXIII Corps area, the DM was fresh and easily overran the German front defences with minimal casualties. When the infantry pressed on, they found that the Germans had dug overlapping flanking positions and deep dugouts, which had protected German infantry from the French artillery. The infantry reached Côte 119, where fire from Souchez stopped the advance. Supporting troops had lagged behind in communication trenches full of wounded and prisoners as German artillery-fire increased and only arrived at 8:00 p.m. German counter-attacks were made using many hand grenades, which caused many casualties. To the north, the 77th and 70th divisions attacked Souchez, where the chemical shells had little effect; the 77th divisional artillery had twice the number of shells than on 9 May but was nullified by the new German defences on reverse slopes, which were immune to fire from guns and could only be engaged by Howitzers, which were brought forward on 15/16 June, only twelve hours before the attack.

On 25 May, three German columns attacked a salient north-west of Bray-en-Laonnois and gained a footing in the French first trench, before being forced out by a counter-attack. On 26 May German attacks on salients east and west of Cerny were repulsed and from 26–27 May, German attacks between Vauxaillon and Laffaux Mill broke down. Two attacks on 28 May at Hurtebise were defeated by French artillery-fire and on the night of 31 May – 1 June, attacks by the Germans west of Cerny also failed. On the morning of 1 June after a heavy bombardment, German troops took some trenches north of Laffaux Mill and were then pushed out in the afternoon. On 2 June a bigger German attack began, after an intensive bombardment of the French front, from the north of Laffaux to the east of Berry-au-Bac. On the night of 2/3 June, two German divisions made five attacks on the east, west and central parts of the Californie Plateau and the west end of the Vauclerc Plateau. The Germans attacked in waves, at certain points advancing shoulder-to-shoulder, supported by flame-thrower detachments and gained some ground on the Vauclerc Plateau, until French counter-attacks recovered the ground. Despite the French holding improvised defences and the huge volumes of German artillery-fire used to prepare attacks, the German organised counter-attacks (Gegenangriffe) met with little success and at Chevreux north-east of Craonne, the French had even pushed further into the Laon Plain.

The shorter intervals between attacks since then had several effects, allowing less time for either side to prepare and the Germans had to take more risks on the rest of the Western Front, to replace tired and depleted divisions in Flanders. German troops and ammunition trains overloaded the rail network in west Flanders, while more German artillery escaped British counter-battery fire and less time was available for wire cutting and pillbox destruction, although the Germans generally left these to give battle in the open. The British artillery preparation before Polygon Wood on 26 September, began 24 hours before the infantry attack. No formal artillery preparation was conducted before 4 October, except for the normal heavy artillery counter-battery fire and destructive fire on German strong-points. To mislead the Germans as to the date and time of the infantry attack, when a hurricane bombardment was to be fired at zero hour, "practice" barrages were begun on 27 September and increased to two barrages a day from 1 October. Despite the ruse of using practice barrages, "a very reliable agent" informed the Germans that an attack was coming from as early as 1 October. The battle was almost called off when heavy rain began again on 2 October, turning parts of the ground into a morass. British military intelligence predicted the German defensive changes after the defeats of 20 and 26 September, in an intelligence summary of 1 October which led to the British being ready for Unternehmen Hohensturm (Operation High Storm), a big German counter-attack to recapture the area around Zonnebeke on 4 October. The attack aimed to complete the capture of the Gheluvelt Plateau by the occupation of Broodseinde Ridge and Gravenstafel Spur. This would protect the southern flank of the British line and permit attacks on Passchendaele Ridge to the north-east. The attack was planned for 6 October, to give the II Anzac Corps time to prepare. Haig was anxious about the possibility of deteriorating weather and on 26 September, was able to order the date to be advanced by two days, because of the quick relief of V Corps by the II Anzac Corps north of the Ypres–Roulers railway.

On 5 July Below reported to Falkenhayn that the new defences were ready and that for the moment the crisis was over. Counter-attacks would not be made until the situation became clear and more Anglo-French attacks were expected. On 6–7 July from Foucaucourt to the Albert–Bapaume road, losses among the German infantry increased rapidly, one crisis merged into the next and the policy of unyielding defence and immediate counter-attack, exposed the defenders to Anglo-French firepower. On the south bank Biaches was lost and at Barleux, Infantry Regiment 89 was subjected to huge amounts of heavy artillery-fire on 9 and 10 July, which demolished trenches and buried soldiers, followed by an infantry attack which was repulsed by the survivors.

The observer wirelessed for an immediate counter-barrage, which obstructed a German counter-attack at 9:00 p.m. so badly, that the German infantry were easily repulsed. Bombing of German-controlled railway centres continued on 9 July, with attacks on Cambrai and Bapaume stations, in which two British aircraft were lost. Le Sars and Le Transloy were attacked in the afternoon and Havrincourt Wood was bombed on 11 July, after suspicions had been raised by increasing amounts of German anti-aircraft fire around the wood. Twenty bombers with seventeen escorts, dropped 54 bombs on the wood and started several fires.

Charbonneau explained that the defeat of the Colonial Corps was caused by faulty reconnaissance, the ineffectiveness of advanced guards in causing delay to advancing German units and that French offensive tactics neglected the importance of obtaining a superiority of fire, which had led to reckless attacks. The quality of the German opponents was not mentioned but German reconnaissance had been effective, communication between commanders and subordinates had not broken down, mutual support between neighbouring units had occurred and German artillery had provided continuous close fire support.[9] At Neufchâteau, the French colonial infantry had been out-gunned and outnumbered by German units, which had been able to engage all their forces quickly. The French XII Corps had a greater number of guns but was not able to overcome two German infantry battalions. German artillery had engaged the Colonial Brigade from close range but when in a hastily occupied defensive position, the French had nullified much of the German artillery-fire; French troops caught in the open had been annihilated. Both sides had attempted to gain fire superiority before advancing and once this had been achieved by the Germans, they had been able to manoeuvre without severe casualties.

In Armee-Gruppe Lochow, the battle for the Labyrnthe continued and from 4 to 6 June, the French attacked Neuville. After an attack on 8 June, the defenders retired to a trench further east. French attacks on the Lorette Spur were co-ordinated with those at Neuville and exhausted the XIV Corps troops, which were replaced by the 7th and 8th divisions of IV Corps, which had been reserved for a counter-attack. To the south, the French had taken the cemetery at Neuville and built a strong point, from which attacks on the rest of Neuville were made, threatening the German hold on the Labyrnthe, 1,600 yd (1,500 m) to the south. By 7 June the defence of Neuville had begun to collapse, despite exhortations from the German high command that the area was to be held at all costs. Officers of the 58th Division wanted permission to withdraw from the village but freedom to make a temporary limited withdrawal in a crisis was given but only to organise a counter-attack. The north-west of the village fell on 8 June, after the last defenders of Infantry Regiment 160 were bombarded by their own artillery. A battalion of the 15th Division was sent to counter-attack a French salient, near the Lossow-Arkade in the Labyrnthe, as soon as it arrived on the Artois front, supported by grenade teams and flame-thrower detachments. The attack failed but the Tsingtau-Graben and some ground at the Labyrnthe was recovered. French attacks at the Labyrnthe were as frequent as those further north and the 1st Bavarian Reserve Division counter-attacked in the early hours of 11 June, which recaptured a trench. French preparations for another general attack were observed by the German defenders and large amounts of artillery ammunition were brought forward. On 10 June the senior gunner in the 15th Division predicted a French attack from Vimy to La Folie, Thélus and Neuville St. Vaast, which if successful, would lead to the loss of the German artillery around Vimy and La Folie. No forces were available for a spoiling attack and at Roclincourt, Reserve Infantry Regiment 99 had watched the French sapping forward to within 66 yd (60 m) of their positions and endured the French preparatory bombardment. The French shelling grew in weight until 11:30 a.m. when a mine was sprung. French infantry attacked, broke into the position and the defenders built flanking barricades to prevent the French from rolling up the flanks of the German position. Other German troops formed a blocking position in front of the French penetration and the German artillery bombarded the lost ground and no man's land, to prevent French reserves from moving forward. Counter-attacks by troops held back in reserve were able to push the French out of their footholds but at the cost of "grievous" losses.

By the end of 1 July, the Sixth Army had captured all of the German first position except Frise on the Somme Canal. Few casualties had been suffered and 4,000 prisoners had been taken. On the south bank, Territorials buried the dead and cleared the battlefield of unexploded ammunition, as artillery was moved forward to prepared positions. I Colonial Corps had advanced within attacking distance of the German second position and indications that the Germans were withdrawing artillery had been detected. In 48 hours, the French had broken through on an 8-kilometre (5.0 mi) front. The advance of I Colonial Corps created a salient and German artillery, safe on the east bank of the Somme and assisted by more aircraft and observation balloons, could enfilade the defences hurriedly built by French troops and make movement on the Flaucourt Plateau impossible in daylight. German counter-attacks at Belloy, La Maisonette and Biaches, increased French casualties. A bold suggestion for a French attack northwards across the river was rejected. By 6 July, Foch had decided to attack on both banks and to extend the attack with the Tenth Army, on the right of the Sixth Army, to exploit success on any part of the front.

The French offensive was defeated in a few days; on the right the First and Second armies advanced on 14 August and were back at their jumping-off points on 20 August. The offensive of the Third and Fourth armies was defeated from 21–23 August and the Fifth Army was defeated on the Sambre and forced to retreat during the same period. Joffre's strategy had failed due to an underestimation of the German armies and the dispersion of the French offensive effort. With a large German force operating in Belgium, the German centre had appeared to be vulnerable to the Third and Fourth armies. The mistaken impression of the size of the German force in Belgium or its approach route, was not as significant as the faulty information about the strength of the German armies opposite the Third and Fourth armies. Joffre blamed others and claimed that the French infantry had failed to show offensive qualities, despite outnumbering the German armies at their most vulnerable point, a claim that Doughty in 2005 called "pure balderdash". The reality was that many of the French casualties were said to have come from an excess of offensive spirit and on 23 August, General Pierre Ruffey concluded that the infantry had attacked without artillery preparation or support during the attack.

The X Corps divisions had managed to take most of their objectives about 700 yd (640 m) forward, gaining observation over the Reutelbeek valley but had relinquished ground in some exposed areas. The British artillery fired a standing barrage for two and a half hours, while the infantry dug in undisturbed and German counter-attacks were dispersed with artillery fire. Wet ground had caused some units to lag behind the creeping barrage, as well as reducing the effect of shells, many landing in mud and being smothered, although this affected German artillery equally. The British had great difficulty moving artillery and ammunition from the west end of the Gheluvelt Plateau to the eastern edge, facing Passchendaele. Field guns closest to Passchendaele were 5,000 yd (4,600 m) from Broodseinde; for the battle of Messines, 6,200 yd (5,700 m) for the 18-pdrs and 7,000 yd (6,400 m) for the 4.5-inch howitzers was the safe maximum. A German officer wrote that the ordeal in the swampy area in the dark and the fog, was indescribable. In 1942, the German official historians recorded in Der Weltkrieg 35,000 casualties for the period 1–10 October. The 45th Reserve Division had 2,883 casualties, whilst the 4th Guard Division suffered 2,786 casualties. 4,759 German prisoners were taken, c. 10,000 since 20 September. Second Army casualties for the week ending 4 October were 12,256, II Anzac Corps lost 3,500 casualties (including 1,853 New Zealanders). The 21st Division had 2,616 casualties, the highest loss of a Second Army division. Fifth Army losses for the week to 5 October were 3,305 men. Calculations of German losses by the Official Historian have been severely criticised ever since. On 5 October, the 21st Division captured a blockhouse and next day a reconnaissance by the 2nd Australian Division revealed Daisy Wood to be strongly held. On 7 October, parties from the 49th Division (II Anzac Corps) raided Celtic Wood and the 48th Division (XVIII Corps) was repulsed at Burns House and Vacher Farm. Celtic Wood was raided by a battalion of the 1st Australian Division on 9 October. There was anxiety among the higher British commanders about wet weather affecting operations again, just as the Germans appeared to be close to collapse.

Three divisions attacked after a three-day artillery bombardment using the new fuze 106. A thaw set in on 16 February, which with the Germans alerted to the attack by a deserter, led to the attack on the south bank advancing only 1,000 yards (910 m) at most and to the capture Boom Ravine (Baum Mulde). The attack on the north bank, to gain observation over Miraumont from the west, succeeded despite the weather and the Germans being forewarned. On the Fourth Army front, fewer attacks took place while the French line was being taken over in stages, southwards to the Amiens–Roye road. On 27 January, the 29th Division took 368 prisoners in an advance of only 400 yards (370 m) and on 1 February, an Australian attack on Stormy Trench was repulsed by a German counter-attack. A second attack on 4 February succeeded. On 8 February, a battalion of the 17th Division took a trench overlooking Saillisel and held it, despite German counter-attacks that continued on 9 February.

Artillery support was similar to that of the 29th Division attack and the objective was gained quickly, with troops wearing sandbags over their boots to grip the ice. German counter-attacks failed but a greater number of casualties were inflicted after the attack, mainly by German artillery fire over the next two days. British attacks on the Fourth Army front ceased until the end of the month. The 8th Division conducted an attack on 4 March, which was prepared in great detail, a practice that had fallen into disuse in 1915, due to the dilution of skill and experience caused by the losses of 1914 and the rapid expansion of the army from 1915–1916.

The 25th Division was ordered by the army commander, General Humbert to attack again at 6:00 p.m. but the orders arrived too late and the attack did not take place. French aircraft were active over the attack front but at midday large formations of German fighters arrived and forced the French artillery-observation and reconnaissance aircraft back behind the front line. By the end of the day the 26th Division had held on to 100 yards (91 m) of the German front trench and the 25th Division had been forced back to its jumping-off trenches. German artillery-fire had not been heavy and the defence had been based on machine-gun fire and rapid counter-attacks. The XIII Corps and XXXV Corps attack due next day was eventually cancelled. The Fifth Army attacked on 16 April at 6:00 a.m., which dawned misty and overcast. From the beginning German machine-gunners were able to engage the French infantry and inflict many casualties, although German artillery-fire was far less destructive. Courcy on the right flank was captured by the 1st Brigade of the Russian Expeditionary Force in France but the advance was stopped at the Aisne–Marne canal. The canal was crossed further north and Berméricourt was captured against a determined German defence. From Bermericourt to the Aisne the French attack was repulsed and south of the river French infantry were forced back to their start-line.
