The U.S. attack was unsuccessful. Monash asked Rawlinson for permission to delay the main attack due on 29 September, but this was refused because of the priority given to Marshal Ferdinand Foch's strategy of keeping the Germans under the relentless pressure of coordinated assaults along the front. As a result of the confusion created by the failed attack (with the corps command being unsure of where the American troops were), the battle on 29 September on the American 27th Division front had to be started without the customary (and highly effective) close artillery support. The British artillery commander argued that attempting to alter the barrage timetable at this late stage would cause problems and the American divisional commander Major General John F. O'Ryan was also concerned about the possibility of friendly fire. All of the Allied commanders therefore agreed to proceed with the original artillery fire plan. The result was that the barrage would now start at the originally-intended jump-off point, some 900 m (1,000 yd) beyond the actual starting point of the infantry, leaving them very vulnerable during their initial advance. 27th Division was required to make an advance greater than any that had been asked of its highly experienced Australian allies, an advance of some 4,500 m (5,000 yd) in a single action. In an attempt to compensate for the lack of a creeping barrage Rawlinson provided additional tanks. However, the absence of a creeping barrage in the 27th Division sector was to have a very detrimental effect on the initial operations of the battle on the front opposite the tunnel.

    German counter-attack, 25 September 1917 Two regiments of the German 50th Reserve Division attacked on a 1,800-yard (1,600 m) front, on either side of the Reutelbeek, supported by aircraft and 44 field and 20 heavy batteries of artillery, four times the usual amount of artillery for a division. The German infantry managed to advance on the flanks, for about 100 yards (91 m) near the Menin road and 600 yards (550 m) north of the Reutelbeek, close to Black Watch Corner, supported by artillery-observation and ground-attack aircraft and a box-barrage fired behind the British front-line, which isolated the British defenders from reinforcements and cut off the supply of ammunition. Return-fire from the 33rd Division (Major-General Reginald Pinney) and the 15th Australian Brigade of the 5th Australian Division (Major-General Talbot Hobbs) along the southern edge of Polygon wood, forced the attackers under cover around some of the Wilhelm Stellung pillboxes, near Black Watch Corner, at the south-western edge of Polygon Wood. German attempts to reinforce the attacking troops failed, due to British artillery observers isolating the advanced German troops with artillery barrages. Plumer ordered the attack scheduled for 26 September to go ahead but modified the objectives of the 33rd Division. The 98th Brigade was to advance and cover the right flank of the 5th Australian Division and the 100th Brigade was to re-capture the lost ground further south. The 5th Australian Division advance the next day began with uncertainty as to the security of the right flank; the attack of the depleted 98th Brigade was delayed and only managed to reach Black Watch Corner, 1,000 yards (910 m) short of its objectives. Reinforcements moved forward into the 5th Australian Division area to the north and attacked south-westwards at noon, as a frontal attack was made from Black Watch Corner without artillery support, because troops were known to be still holding out. The attack succeeded by 2:00 p.m. and later in the afternoon, the 100th Brigade re-took the ground lost north of the Menin road.

    A German counter-attack at 2:30 p.m. was driven off and more ground re-taken by the 100th Brigade on the right. A pillbox near the Menin road taken at 4:00 p.m. was the last part of the area captured by the German attack the previous day to be re-taken. A German counter-attack at 5:00 p.m. was stopped by artillery fire. I Anzac Corps attacked with the 5th Australian Division on the right. In the 15th Australian Brigade the battalions were to advance successively but bunched up near the first objective and were stopped by pillboxes at the "racecourse" and fire from the 33rd Division area to the south. At 7:30 a.m. the right-hand battalion dug in at the boundary with the 33rd Division and the other two advanced to the second objective by 11:00 a.m. The left brigade assembled in twelve waves on a strip of ground 60 yd (55 m) deep and avoided the German barrage fired at 4:00 a.m. which fell behind them and advanced through the fog 500 yd (460 m) almost unopposed to The Butte. At some pillboxes there was resistance but many German soldiers surrendered when they were rapidly surrounded. The Butte was rushed and was found to be full of German dugouts. Two battalions passed through at 7:30 a.m. towards the second objective, a 1,000-yard (910 m) stretch of the Flandern I Stellung and some pillboxes, until held up by fire from a German battalion headquarters on the Polygonebeek. A reserve battalion overran the dugouts and more pillboxes nearby, advancing to just beyond the final objective, at the junction with the 4th Australian Division to the north, taking 200 prisoners and 34 machine-guns. An attempted German counter-attack by part of the 17th Division, was dispersed by artillery and machine-gun fire. The 4th Australian Division assembled well forward and avoided the German barrage by squeezing up into an area 150 yd (140 m) deep and attacked at 6:45 a.m. with two brigades. The right brigade attacked through a mist, took the first objective with only short delays to capture pillboxes but then mistakenly advanced into the standing barrage, which had paused for twice as long as usual, to assist the 3rd Division advance through muddier conditions to the north and had to be brought back until the barrage moved forward.

    The task of clearing the village was given to the depleted 16th (Irish) Division. Its two attacking brigades (47th and 48th) were supported on the right by 56th Division's operations in Leuze and Bouleaux Woods. Precisely at 4.45pm on 9 September, 48th Brigade rushed towards Ginchy from the south-west but was instantly halted by a ferocious German barrage. Two minutes later, 47th Brigade's attack (from the south) was immediately cut down by close range machine-gun fire.

    From 4–6 May, the battle in the 2nd Australian Division sector continued and the foothold in the Hindenburg Line was extended. The 7th Division continued to try to reach British parties, which had got into Bullecourt and been isolated. A German counter-attack on 6 May was defeated but the 2nd Australian Division and the 62nd Division had been exhausted and serious losses had been inflicted on the 1st Australian and 7th divisions. The German 27th, 3rd Guard, 2nd Guard Reserve divisions and a regiment of the 207th Division had made six big counter-attacks and also had many casualties. The British attacked again on 7 May with the 7th Division towards Bullecourt and the 1st Australian Brigade west along the Hindenburg trenches, which met at the second objective. Next day the "Red Patch" was attacked again and a small part held after German counter-attacks.

    The British were greatly helped by the fact that they were in possession of highly detailed captured plans of the enemy defences (especially useful for the IX Corps sector). Monash's battle plan for 29 September envisaged breaking through the main Hindenburg Line defences, crossing the canal tunnel mound, breaching the fortified Le Catelet–Nauroy Line beyond that, and reaching the Beaurevoir Line beyond that (the final fortified line) as the objective on the first day. Monash had originally intended to capture the Beaurevoir Line on 29 September, but Rawlinson removed this as a first day objective, considering it overly ambitious. King George V at Riqueval Bridge, the scene of the exploit of the 137th Brigade when the 46th Division crossed the St. Quentin Canal cutting on 29 September 1918. (photo taken 2 December). Attack over Bellicourt Tunnel On 29 September, the two American divisions attacked followed by the two Australian divisions, with approximately 150 tanks of the 4th and 5th Tank Brigades of the British Tank Corps (including the newly trained American 301st Heavy Tank Battalion, which was equipped with British tanks) in support of the four divisions. The objective of the Americans was the Le Catelet-Nauroy Line, a defensive line east of the canal. Here the Australian 3rd Division (behind the U.S. 27th) and 5th Division (behind the U.S. 30th) were intended to "leapfrog" through the American forces and press on towards the Beaurevoir Line. Australian 2nd Division was in reserve. On the left of the front, where the U.S. 27th Division began at a disadvantage, none of the objectives was met on the first day and the Americans suffered severe losses. The 107th Infantry Regiment suffered the worst casualties sustained in a single day by any U.S. regiment during the war. Rather than leapfrogging through the Americans, the Australian 3rd Division became involved in a desperate fight for positions that should already have been captured had Monash's plan run to timetable. Despite some individual acts of heroism the lack of progress on the left of the front had an adverse effect on the progress of the right of the front too. As the American 30th Division and then the Australian 5th Division moved forward whilst the units to their left did not, they had to contend with German fire from the side and rear as well as from ahead. An added difficulty was thick fog across the battlefield in the earlier stages of the attack which led to American troops passing by Germans without realising that they were there, with the Germans causing severe problems to the Americans following the assault wave.

    The 159th Regiment advanced over a hillock, met uncut wire and massed fire from small arms and artillery, out of view of the French front line. The 97th Regiment captured Souchez cemetery with few casualties but the repulse of the 159th Regiment uncovered the flanks of the 97th Regiment and the adjacent DM, which made an attack on Souchez village impossible. An attack by the 159th Regiment at 4:00 p.m. was also stopped immediately by German return fire. In the XXI Corps area, the 70th Division was bombarded by German artillery as the attack began, in response to flares sent up from the German front line. The 42nd BCP took part of Château Carleul against determined German resistance but then stopped to maintain contact with the 77th Division to the right. The 360th and 237th regiments were met by a wall of fire and were not able to advance, except on the far left flank, where the 13th Division had managed to push forward for 160 yd (150 m). The 48th Division on the northern flank of XXI Corps, advanced for about 0.62 mi (1 km) and took its initial objectives in 25 minutes, in a costly attack. At zero hour, the 43rd Division on the left of XXI Corps, blew a mine under the German defences opposite and rushed the crater with few losses, before the Germans could counter-attack. D'Urbal ordered the attack to continue on 17 June, on the fronts of the 77th Division and IX Corps on either flank of XXXIII Corps, where the most advanced positions of the DM had become untenable. The attack was ordered for 4:00 p.m. and then postponed, leading to some units attacking too early, being pinned down in front of uncut wire and then being bombarded by French as well as German artillery. The 70th Division and the XXI Corps divisions on the northern flank, took several German positions in costly attacks but the IX Corps attack on the southern flank was deluged with artillery and machine-gun fire and made no progress. On 18 June d'Urbal concentrated the remaining offensive capacity of the Tenth Army against Vimy Ridge. IX Corps was ordered to ignore the German defences in Neuville but General Balfourier the XX Corps commander, refused to attack with the northern flank unsupported. The attack on 18 June was another failure, in which French infantry were again confronted by German positions on reverse slopes, invisible to ground observation and undamaged, with uncut wire and alert defenders, who inflicted many casualties on the attackers. Foch suspended the offensive but d'Urbal reverted to piecemeal attacks for another week until Joffre intervened and ended the offensive.

    On 15 September Generalfeldmarschall Crown Prince Rupprecht, commander of the northern group of armies, was ordered to prepare a rear defensive line and on 23 September work on the new Siegfriedstellung (Hindenburg Line) began. On 21 September, after the battle of Flers–Courcelette (15–22 September), Hindenburg ordered that the Somme front was to have priority in the west for troops and supplies. By the end of the Battle of Morval (25–28 September) Rupprecht had no reserves left on the Somme front. During September, the Germans sent another thirteen fresh divisions to the British sector and scraped up troops wherever they could be found. The German artillery fired 213 train-loads of field artillery shells and 217 train-loads of heavy ammunition, yet the début of the tank, the defeat at the Battle of Thiepval (26–28 September) and the number of casualties (September was the costliest month of the battle for the German armies) had been severe blows to German morale.

    At zero + 130 minutes, it was to advance in 100 yd (91 m) lifts every eight minutes to the final objective. After another pause the barrage was to creep forward at hourly intervals for 1,500 yd (1,400 m) into the German defences. The defensive barrage by the first two belts from the field artillery was to stop at 11:20 a.m. except for SOS fire and the two back belts of heavy and medium artillery at 1:44 p.m. German defensive preparations Main articles: 4th Army defensive changes: September–November 1917 and Actions of 30 September – 4 October 1917 From mid-1917, the area east of Ypres was defended by six German defensive positions: the front line, Albrechtstellung (second position), Wilhelmstellung (third position), Flandern I Stellung (fourth position), Flandern II Stellung (fifth position) and Flandern III Stellung (under construction). In between the German defence positions lay the Belgian villages of Zonnebeke and Passchendaele. The German fortifications had been breached in several places since the start of the British assault on 31 July 1917. Ludendorff met the local commanders at Roulers on 29 September where the "complete breakdown" of the German defensive system was described to him; Ludendorff ordered a strengthening of forward garrisons by the ground-holding divisions. All available machine-guns including those of the support and reserve battalions of the front line regiments, were sent into the forward zone to form a cordon of four to eight guns every 250 yd (230 m). Ground holding divisions were reinforced by the Stoss regiment of each of the Eingreif divisions, which were moved up behind each front division into the artillery protective line, which backed on to the forward battle zone, to launch earlier counter-attacks while the British were consolidating. The bulk of the Eingreif divisions were to be held back and used for a methodical counter-stroke on the next day or the one after and for spoiling attacks between British offensives. These changes were incorporated in a 4th Army operation order of 30 September.

    Next day, the division attacked Aisne Farm and was repulsed but the neighbouring 58th Division took Spot Farm. On 5 September, the 61st Division tried again at night, took a German outpost on Hill 35 and then lost it to a counter-attack. An attack from south of Hill 35 by the 42nd Division with the 125th Brigade and part of the 127th Brigade, took place on 6 September. For several days, practice barrages were conducted and a daylight reconnaissance by a small party probed to within 25 yd (23 m) of Beck House. During the night, the Germans sent up many flares and rockets, disclosing their barrage line and many undetected posts. The British barrage schedule required four rounds per-gun-per-minute but the gunners fired up to ten. The 125th Brigade attacked Iberian, Borry and Beck House farms and captured Beck House but small-arms fire from Hill 35 stopped the rest of the attack, which was a costly failure. The Germans retook Beck House at 10.45 a.m. and enfiladed the rest of the attackers, who were withdrawn, except on the extreme right. Another German counter-attack at 7.30 p.m. by fresh storm-troops forced the battalion to retire, except from a small area 150 yd (140 m) forward, which was abandoned next day; the division had c. 800 casualties. Another night attack by the 61st Division on Hill 35 failed and in the XVIII Corps area, a company of the 51st Division made an abortive raid on Pheasant Trench. Two battalions of the 58th Division conducted raids on 8 September and next day the 24th Division in II Corps, withstood another determined German attack at Inverness Copse. On 11 September, a night attack by a battalion of the 42nd Division failed to capture The Hut. A covering party for a group of soldiers working in no man's land discovered an Inniskilling Fusilier, who had lain out wounded since 11 August, subsisting on rations recovered from dead soldiers. On 13 September, the Guards Division was pushed back from the far side of the Broembeek and the Wijdendreft road.

    The 5th Australian Division relieved the 2nd Australian Division by 10 May, while the battle in Bullecourt continued to the west, the 7th Division capturing the village except for the Red Patch on 12 May, while the 62nd Division advance was pushed back. The 58th Division relieved the Australians and British attacks on 13 May failed. A final German counter-attack was made to recapture all of Bullecourt and the Hindenburg trenches on 15 May. The attack failed, except at Bullecourt where the west of the village was regained. The 7th Division was relieved by part of the 58th Division, which attacked the Red Patch again on 17 May and captured the ruins, just before the Germans were able to withdraw, which ended the battle. The Fifth Army lost 14,000–16,000 casualties and German losses in two divisions were 4,500 casualties, with casualties in the regiments of five other divisions engaged being c. 1,000 at a minimum. Total British losses for both Bullecourt operations were 19,342.
