The Impact of Barrage Fire and Specialized Artillery in World War I| OKWAVE

英文を訳して下さい。

Surplus field artillery brigade headquarters planned forward moves for the guns and were kept ready to replace casualties. It was expected that much of the artillery would need to switch rapidly from the bombardment plan to engage counter-attacking German infantry. It was planned that the Forward Observation Officers of the divisions in the first attack onto the ridge would control the artillery which had remained in place and the reserve divisions advancing down the far slope to the Oosttaverne line would control the artillery hidden close to the front line and the artillery which advanced into no-man's-land. Franks planned to neutralise German guns within 9,000 yards (8,200 m) of the attack front. On the flanks of the British attack front of 17,000 yards (16,000 m), 169 German guns had been located, for which 42 British guns (25 percent of the German total) were set aside. The 299 German guns in the path of the attack were each to be engaged by a British gun, a formula which required 341 British guns and howitzers to be reserved for counter-battery fire. Every 45 yards (41 m) of front had a medium or heavy howitzer for bombardment, which required 378 guns, with 38 super-heavy guns and howitzers (5 percent) deployed with the field artillery that was due to fire the creeping and standing barrages. Franks devised a bombardment timetable and added arrangements for a massed machine-gun barrage. The 756 medium and heavy guns and howitzers were organised in forty groups and the 1,510 field guns and howitzers in sixty-four field artillery brigades within the attacking divisions and thirty-three Army field artillery brigades, divided among the three attacking corps.

Ammunition weighing 144,000 long tons (146,000 t) was delivered with 1,000 shells for each 18-pounder, 750 shells per 4.5-inch howitzer, 500 rounds for each medium and heavy piece and another 120,000 gas and 60,000 smoke shells for the 18-pounder field guns. Australian truck near Hill 63 during a bombardment of ANZAC batteries in Messines (AWM E00649). Two thirds of the 18-pounders were to fire a creeping barrage of shrapnel immediately ahead of the advance, while the remainder of the field guns and 4.5-inch howitzers were to fire a standing barrage, 700 yards (640 m) further ahead on German positions and lift to the next target, when the infantry came within 400 yards (370 m) of the barrage. Each division was given four extra batteries of field artillery, which could be withdrawn from the barrage at the divisional commander's discretion to engage local targets. The field batteries of the three reserve divisions were placed in camouflaged positions, close to the British front line. As each objective was taken by the infantry, the creeping barrage was to pause 150–300 yards (140–270 m) ahead and become a standing barrage, while the infantry consolidated. During this time the pace of fire was to slacken to one round per-gun per-minute, allowing the gun-crews a respite, before resuming full intensity as the barrage moved on. The heavy and super-heavy artillery was to fire on German artillery positions and rear areas and 700 machine-guns were to fire a barrage over the heads of the advancing troops. At 03:00 a.m. the mines would be detonated, followed by the attack of nine divisions onto the ridge. The blue line (first objective) was to be occupied by zero + 1:40 hours followed by a two-hour pause. At zero + 3:40 hours the advance to the black line (second objective) would begin and consolidation was to start by zero + 5:00 hours.

On the northern flank two infantry companies, engineers and pioneers were placed to establish the defensive flank on the left. The divisional artillery and an army field brigade with 54 × 18-pdr field guns and 18 × 4.5-inch howitzers provided fire support, with three field batteries from the 62nd Division further north, to place a protective barrage along the northern flank. The darkness, fog and mud were as bad as on the south bank but the German defence was far less effective. The creeping barrage moved at 100 yards (91 m) in four minutes, slower than the rate on the south bank and the Germans in a small number of strong-points were quickly overcome. The objective was reached by 6:40 a.m. and the defensive flank established, a final German strong-point being captured at 10:50 a.m. No German counter-attack was made until next day, which was stopped by artillery-fire.

The main attack was made by X Corps and the 1st Anzac Corps, on a 4,000 yd (3,700 m) front on the Gheluvelt plateau. Steady pressure in early September from the 47th Division, had advanced the British front line near Inverness Copse for a considerable distance, which made better jumping-off positions for the attack by the Australians. The four divisions advanced behind a creeping barrage of unprecedented weight. The increased amount of artillery allowed the heavy guns to place two belts of fire beyond the two from the field artillery; a machine-gun barrage in the middle made five belts, each 200 yd (180 m) deep. The creeping barrage started quickly, lifting 100 yd (91 m) every four minutes and this allowed the British infantry to surprise the German outpost garrisons while the Germans were still in their shelters, by looming out of the mist. After four lifts, the barrage slowed to 100 yd (91 m) every six minutes. Most German troops encountered were so stunned by the bombardment, that they were incapable of resistance and surrendered immediately, despite few of the concrete pillboxes and Mebu shelters being destroyed by the British artillery. In the few areas where the German defenders were capable of resisting, they inflicted many losses but were quickly outflanked in the mist. The new system of local reserves allowed the British to maintain momentum, despite local checks. The 41st Division had to advance across the Bassevillebeek valley, against the right of the German 9th Division and the left of the Bavarian Ersatz Division, to capture Tower Hamlets spur. The advance was hampered by overnight rain, which affected the valley more than the plateau to the north. Fire from camouflaged German machine-gun nests in the valley caused confusion and delay to the infantry, who lost the barrage. The Bassevillebeek stream in the valley was eventually crossed, with the 122nd Brigade struggling forward and the 124th Brigade being held up near the British front line, by numerous machine-guns in the Quadrilateral, three ruined cottages that had been fortified behind a digging 400 yd × 100 yd (366 m × 91 m) at the south end of the spur.

A barrage drill was devised, to prevent the opponent from manning his parapets and installing machine-guns, in time to meet the assault. Attacks were supported by creeping barrages, standing barrages covered an area for a period of time, back barrages were to cover exploitation by searching and sweeping ground, to catch troops and reinforcements while moving. One 18-pdr for each 15 yards (14 m) of barrage line was specified, to be decided at the corps artillery headquarters and creeping barrages should move at 100 yards (91 m) a minute and stop 300 yards (270 m) beyond an objective, to allow the infantry room to consolidate. Surplus guns were added the barrage, to be ready to engage unforeseen targets. A limit of four shells per minute was imposed on 18-pdr guns, to retard barrel wear (before 1917 lack of ammunition had made barrel-wear a minor problem) and use of smoke shell was recommended, despite the small quantity available. Ammunition expenditure rates were laid down for each type of gun and howitzer, with 200 shells per gun per day for the 18-pdr.

On 16 May Haig resumed the offensive with the Battle of Festubert, which was fought on the right flank of the Aubers Ridge battlefield, where British troops were ordered to press on to local objectives only after consolidating. By the morning of 17 May, the German 14th Division was forced to retire to a new breastwork dug .75 mi (1.21 km) behind the original front position, connecting the Stützpunktlinie (strongpoint line) behind the front line, with the result that British bombardments and attacks met only small parties of rearguards. The Quadrilateral was captured at about 10:15 a.m. on 17 May after an extensive bombardment led to a large number of German troops surrendering. Reinforcements doubled the German firepower in the new position, from which in the afternoon British attempts to continue the advance were repulsed. Low cloud and rain obscured the battlefield and it took three days for the British to identify the new line. A series of attacks by four British divisions from 18–25 May achieved minor advances of the British line but found that the captured positions had been registered by German artillery, which maintained a heavy bombardment, which forced the British back at some places and inflicted many casualties. The fighting cost the British 16,644 casualties and the Germans c. 5,500. Fighting continued until 25 May for local objectives against German reinforcements, which were not available to oppose the French further south. The eight days, that Foch thought necessary to capture ground on the flanks of XXXIII Corps, took five weeks to achieve. Small advances were made but the Germans were able to improve their defences relatively easily, in dips and behind slopes. Artillery reinforcements were registered as they arrived on obvious avenues of attack, which required only notification by flare signals from the front line to commence firing. The Tenth Army also received substantial reinforcements of artillery but these made only a small net increase, due to losses from German artillery fire, mechanical failures and premature detonations. Infantry reinforcements were only marginally greater than losses. Artillery ammunition for the 355 heavy and 805 field guns was much greater for the second general attack, with 718,551 shells available from 16 to 18 June, compared to 265,430 fired from 3 to 9 May. The preliminary bombardment was to begin on 10 June and concentrate on certain areas to conceal the imminence of an infantry attack. On the day of the attack, the artillery was to destroy defences repaired by the Germans overnight and conduct counter-battery fire until the last moment, as a deception, then fall on the German front defences as the French infantry advanced, to mislead the Germans and get the infantry across no man's land before a German barrage began.

Fifth Army See also: Capture of Wurst Farm The Fifth Army attacked on the left of the Second Army to capture the Wilhemstellung, with V Corps on the right and XVIII Corps on the left, to finish the capture of the line from Schuler Farm to Langemarck and then advance 500–800 yd (460–730 m) east towards Poelcappelle; XIV Corps formed the northern flank with the 20th Division. V Corps had more field guns than the I Anzac Corps to the right and fewer heavy guns, so only a three-layer barrage was possible. A creeping barrage by 18-pounder field guns was to move at the same speed as that of the Second Army. 18-pounder and 4.5-inch howitzer fire were to comb the area in front of the creeping barrage, from 100–400 yd (91–366 m) deep and a neutralising barrage by 6-inch howitzers and 60-pounder guns was to sweep ground 450–1,200 yd (410–1,100 m) in front of the creeping barrage. Artillery not needed for counter-battery fire was to put standing barrages on the most dangerous German positions, like Hill 37 and Hill 40 and German assembly areas in the dips behind Zonnebeke and Gravenstafel. The 9th and 55th Divisions of V Corps were to attack on fronts of 1,800 yd (1,600 m) over ground held by the right of the German 121st Division and the 2nd Guards Reserve Division, which had also changed hands twice in August. The large numbers of strong points, pillboxes and fortified farms east of the Hanebeek and Steenbeek streams were mostly intact, despite numerous attempts to smash them with artillery fire. The artillery brought to the Ypres salient in September went to the Second Army so the Fifth Army adopted a new infantry formation, where moppers-up were reorganised into small groups of up to half a platoon, moving with the leading assault waves, to capture specific strong-points and then garrison them. XVIII Corps adopted the same practice, which became standard in the Fifth Army soon after the battle. The 9th Division was confronted by the morass of the Hanebeek valley, where the stream had been choked by frequent bombardment and turned into a swamp and water-filled shell-holes.

Overall the results of the four-day preliminary artillery bombardment proved unsatisfactory. The Allied fire did not cause severe damage to the Bulgarian and German defensive line while the greater focus of the artillery fire on some points of the line gave a clear indication of the directions where the main attack was to be delivered. The defenders also used every possible moment to repair the damage to their fortifications under the cover of their own artillery. It must also be noted that the Bulgarian and German artillery and its observations posts were practically untouched by the Allied bombardment. While the Bulgarian infantry units suffered 945 casualties during the four day of bombardment, the losses of the artillery were only 10 men killed or wounded and several guns damaged or destroyed. The beginning of the infantry attack was set by the Allied command for 6:30 on 9 of May and as the infantry prepared the artillery resumed its barrage with much greater vigor, once again engulfing the entire defensive line in a cloud of smoke and dust. At precisely 6:30 the Italian, French and Russian infantry moved out of their trenches and advanced against the Bulgarian and German positions along an 11-kilometer long line.The 35th Italian Infantry Division attacked the Bulgarian 2/2 Infantry Brigade and German 201st Infantry Brigade with its Sicilia and Ivrea infantry brigades(61st, 62nd, 161st and 162nd infantry regiments). The focal points of the assault were the powerful positions on Hill 1020 and Hill 1050. To the right parts of the 61st regiment took advantage of the dust cloud, left by the barrage, and managed to capture a forward trench that the Bulgarians had evacuated in order to preserve their infantry from the Allied artillery fire.

On the left flank of the division, Bethmann-Hollweg Trench to the north-east of Mont Sans Nom, was captured along with six guns, which secured Mont Sans Nom from an attack against the eastern slope. c. 1,100 prisoners, 22 guns, sixty mortars and 47 machine-guns were captured by the Foreign Legion. On 25 April, the 34th Division was relieved by the 19th Division. In the attack of 17 April, the Fourth Army had swiftly reached the crest of the Moronvilliers massif but German observation over the battlefield had enabled accurate German artillery-fire against the French infantry. The attack had been costly, despite fog protecting the French infantry from the fire of some German machine-guns. Tunnels driven through the chalk connected the foremost German positions with the rear. German infantry could fire until the last moment, then retire through them to the northern slopes. French heavy artillery-fire blocked some tunnels, subways, deep dugouts and caverns, entombing German troops and others were overrun and captured. As the French infantry encountered the German reverse-slope defences, fatigue, losses and the relatively undamaged state of the German positions, stopped the French advance. Possession of the crest was a substantial tactical advantage for the French, which denied the Germans observation to the south.

During the pause on the ridge crest, an observer reported that the Oosttaverne line was barely occupied, at 2:00 p.m. a balloon observer reported a heavy German barrage on the II Anzac Corps front and a counter-attack patrol aircraft reported German infantry advancing either side of Messines. The German counter-attack was "crushed" by artillery fire by 2:30 p.m. Each corps squadron kept an aircraft on counter-attack patrol all day, to call for barrage fire if German troops were seen in the open but the speed of the British advance resulted in few German counter-attacks. Artillery observers watched for German gunfire and made 398 zone calls but only 165 managed to have German guns engaged. The observers regulated the bombardment of the Oosttaverne line and the artillery of VIII Corps to the north of the attack, which was able to enfilade German artillery opposite X Corps. Fourteen fighters were sent to strafe from low altitude, German ground targets ahead of the British infantry, roving behind German lines, attacking infantry, transport, gun-teams and machine-gun nests; the attacks continued all day, with two of the British aircraft being shot down. Organised attacks were made on the German airfields at Bisseghem and Marcke near Courtrai and the day bombing squadrons attacked airfields at Ramegnies Chin, Coucou, Bisseghem (again) and Rumbeke. Reconnaissance reports of German troops concentrating from Quesnoy–Warneton, led to aircraft setting out to attack them within minutes. German fighters made a considerable effort to intercept corps observation aircraft over the battlefield but were frustrated by patrols on the barrage line and offensive patrols beyond; only one British corps aircraft was shot down by German aircraft during the day. After dark, the night-bombing specialists of 100 Squadron bombed railway stations at Warneton, Menin and Courtrai.

From 10 to 16 June the French fired 497,122 shells with less effect than the 265,430 rounds fired from 3 to 9 May. The Germans had managed to fire a heavy artillery barrage of c. 100,000 shells, which stopped the French infantry attack and prevented troops moving up in support. Attempts to repeat the surprise of 9 May by ruses failed and a German counter-barrage had begun in no man's land within two minutes of the French infantry advance. The experience of the attacks on 16 June demonstrated that the effect of counter-battery fire, neutralising fire and changes in the pattern and timing of artillery-fire made no difference if the German wire was uncut when the infantry advance began. German field defences were dug in increasing quantity and complexity during the offensive and German artillery became much more active, as more guns and much more ammunition arrived at the battlefront. A considerable tactical advantage had been gained by the French, who had regained 6 sq mi (16 km2) of ground. The new German defences around the area were on ground overlooked from the Lorette Spur, were more costly to defend and made Vimy Ridge more vulnerable to attack. The apparent lost opportunity on 9 May, when Vimy Ridge was captured in the first rush, led the French army commanders to conclude that more of the same could achieve a breakthrough if better organised, which formed the basis of the planning for the autumn offensives in Artois and Champagne. Pétain wrote that the attack on 9 May showed that a breakthrough was possible and that it could be achieved by careful preparation of communication trenches, jumping-off trenches and assembly positions, if the German defences were carefully reconnoitred and sufficiently bombarded by artillery. Since the defenders could close a gap quickly it would be necessary to maintain momentum, with reserve troops following up the attacking force closely. Attacks in open country were preferable to being bogged down in fighting for obstacles like villages and woods and the attack should be on a broad front, to allow centres of resistance to be outflanked and to disperse German fire power over a wider area. German analysis of the battle was collected in a memorandum of June 1915 and led to renewed emphasis on infantry shelters, deep enough to be invulnerable to heavy artillery and to increase the number of defensive positions behind the front, which would slow an advance and delay subsequent attacks, by forcing the attacker to move artillery into range. On 7 June a copy of Note 5779 was captured on the Artois front and the local corps commander ordered that intensive digging be undertaken and stipulated that reserve positions were to be as solidly built as front line defences.

Lukin sent messages urging Tanner and the battalion commanders to dig in regardless of fatigue, as heavy artillery fire was expected during the night or early the next morning. As night fell German high explosive and gas shelling increased in intensity and a German counter-attack began at midnight with orders to recapture the wood at all costs. The attack was made by three battalions from the 8th and 12th Reserve divisions and managed to reach within 50 yards (46 m), before being driven under cover by artillery and machine-gun fire. Later that night, fire into Delville Wood from four German Feldartillerie brigades reached a rate of 400 shells per minute.

A shortage of heavy weapons handicapped the British. Only their 60-pounders (four guns to a division) were powerful enough to shell enemy gun emplacements from the Aisne's south shore, and these guns were inferior to German artillery in calibre, range and numbers. Four artillery battery of 6-inch (150 mm) guns (a total of sixteen), were rushed from England. Although a poor match against the German 8-inch (200 mm) howitzers, they helped somewhat. Defensive firepower was limited to rifles and two machine guns allotted to each battalion. The British regulars were excellent marksmen but even their combined accuracy was no match for the German machine guns and grenades. British aircraft were used to report troop movements, although few were equipped with wireless. Aviators were able to recognise the advantage of observing artillery fire. On 24 September, Lieutenants B.T. James and D.S. Lewis detected three well-concealed enemy gun batteries that were inflicting considerable damage on British positions. They radioed back the location of the batteries, then droned in a wide circle, waiting to spot their own gunners' exploding shells. Anti-aircraft fire was desultory and inaccurate. The German Army used only percussion shells, which, according to Canadian sources, "not one in several hundred ever hit its aerial target, and fell to earth frequently at some point in the British lines and there burst." For a three-week period following the unexpected development of trench warfare, both sides gave up frontal assaults and began trying to envelop each other's northern flank. The period is called "Race to the Sea". As the Germans aimed for the Allied left flank, the Allies sought the German right wing. The western front thus became a continuous trench system of more than 400 miles (640 km). From the Belgian channel town of Nieuwpoort, the trench lines ran southward for many miles, turning southeast at Noyon, continuing past Reims, Verdun, Saint-Mihiel and Nancy; then cutting south again to the northern Swiss border twenty miles (32 km) east of Belfort. Meanwhile, the Belgian Army became a growing threat to German communications as the battle shifted northward. The Germans made plans on 28 September to capture the port of Antwerp and crush the Belgian forces. This important maritime city was encircled by an obsolete fortress system that could not withstand even 6-inch shells. An outer ring of eighteen forts ranged from seven to nine miles from the city, an inner ring from one to two miles. Each fort had two machine guns, but lacked telephone communications and means for observing gunfire. One 6-inch gun poked out at each mile; none of these forts had high explosive projectiles or smokeless gunpowder and several thousand surrounding acres had been cleared to provide unobstructed fields of fire.

VIII Corps and II Corps conducted a larger operation on the night of 1/2 December and the British tried to cross the danger zone without artillery support to forestall the German artillery. Because of the moonlight, the infantry had to form up well behind their outpost line and many of the troops got stuck in the mud and some were caught by German machine-gun fire. The slow advance left some troops in the German barrage zone when the German artillery opened fire a minute after the start of the British barrage but the German outpost zone was overrun and the main line of defence breached at one point. After a local truce to recover wounded, a German counter-attack forced the 32nd Division back to the start line and the 8th Division dug-in about 100 yards (91 m) forward on the left and 200 yards (180 m) on the right. More British attacks were easily stopped by the Germans and at 4:10 p.m. a German counter-attack was easily repulsed by the British. The attack failed to gain much ground but the German 25th Division had to be relieved on 3 December. On 3 December, two battalions of the New Zealand Division attacked the Polderhoek Spur to shield the area north of the Reutelbeek stream from German observers at Gheluvelt further south. The attack was made in daylight as a ruse, in the hope that the unusual time would surprise the German defenders, who would be under cover sheltering from the bombardments being fired at the same time each day. The ruse failed, some British artillery-fire dropped short on the New Zealanders, the Germans engaged the attackers with small-arms fire from Polderhoek Spur and Gheluvelt ridge and winds ruined a smoke screen. The New Zealanders suffered many casualties and were forced under cover 150 yards (140 m) short of the first objective; another attempt after dark was cancelled because of the full moon and sight of German reinforcements reaching Polderhoek Château. German counter-attacks were repulsed over the next few days and the New Zealanders handed over to troops of IX Corps. The Germans used an observation balloon accurately to direct artillery-fire and on 14 December, the ground was re-captured by a German counter-attack.

The ammunition included 200 rounds of 4.1-inch ammunition for the remaining Konigsberg guns and 300 shells for other guns. The 3rd Battery South African Field Artillery deployed on the river bank and supported a crossing by part of the brigade headed by the 5th South African Horse which reached a ridge on the east side of the river. Captain Bloomfield’s Scouts were deployed forward of the ridge but the other South African troops on the ridge were halted by heavy fire from higher ground to their front and from a defended farm to the north.

Unternehmen Strandfest (Operation Beach Party) began with a German artillery bombardment on 6 July, though not of an intensity sufficient to suggest an attack. The dawn of 9 July was wet and stormy, so Strandfest was postponed for 24 hours at 6:10 a.m., about two hours before zero hour. The next day was overcast, with a strong wind and the bombardment increased at 5:30 a.m. The British floating bridges near the coast were destroyed and near Nieuport, only one bridge and the lock-bridge remained intact. By 10:15 a.m., telephone and wireless contact with the British front was lost. The shelling was heaviest from the Geleide Brook to the coast, held by the 2nd Brigade of the 1st Division and by 11:00 a.m., the two British battalions had been cut off. Before noon all the German artillery and mortars began firing, except for twenty-minute periods at 2:00 p.m., 4:00 p.m. and 7:00 p.m. for observation. The breastworks on the British side were only 7 ft (2.1 m) high and 3 ft (0.91 m) thick and collapsed immediately. Sand clogged the defenders' rifles and machine-guns and the Germans used Yellow Cross (mustard gas) and Blue Cross gas shells for the first time, mainly for counter-battery fire, which reduced the British artillery to a "feeble" reply. German aircraft made low-altitude strafing attacks and by late afternoon, the British troops on the west bank of the Yser were pinned down. The British artillery defence plan was implemented, with one-hour bombardments of German trench lines at 9:30 a.m., 11:25 a.m. and 2:10 p.m., which were ineffective against German concrete shelters. The German artillery had a 3:1 advantage in numbers and to conceal their presence, many British guns had not registered, only 153 coming into action.

German 2nd Army attack On 17/18 April, the Germans bombarded the area behind Villers-Bretonneux with mustard gas, causing 1,000 Australian casualties. On the evening of 23/24 April, an artillery barrage was fired, using mustard gas and high explosive rounds. Next morning, the Germans attacked the village with four divisions. The German infantry, with fourteen supporting tanks (one was unserviceable), broke through the 8th Division, making a 3-mile (4.8 km) wide gap in the Allied line. Villers-Bretonneux fell to the Germans and the railway junction of Amiens became vulnerable to capture. After the Germans took Villers-Bretonneux, the first engagement between opposing tanks took place. Three British Mark IV tanks from No. 1 Section, A Company, 1st Battalion, Tank Corps had been dispatched to the Cachy switch line, at the first reports of German advance and were to hold it against the Germans. One was a "male" (the No. 1 Tank of the section) armed with two 6-pounder guns and machine guns, under the command of Lieutenant Frank Mitchell. It was crewed by only four of the normal crew of eight, as the others had been gassed. The other tanks were "females" armed with 0.303 in (7.7 mm) machine-guns, for use against infantry. All were advancing when they encountered a German A7V, "Nixe" of Abteilung III Imperial German Tank Force, commanded by 2nd Lieutenant Wilhelm Biltz. Nixe fired on the two "females", damaging them to the extent that it left holes in the hull leaving the crew exposed. Both retreated; their machine guns were unable to penetrate the armour on the German tank. Mitchell's "male" Mark IV continued to fire at the A7V, while on the move to avoid German artillery fire and the gun of the German tank. The movement meant Mitchell's gunner had difficulty in aiming the 6-pounders. The tanks fired at each other on the move, until the Mark IV stopped to allow the gunner a clear shot and the gunner scored three hits (a total of six shell hits). Nixe heeled over on its side, possible as a result of crossing an incline at the wrong angle. The surviving German crew (out of 18 men), including Biltz, alighted from the vehicle and the British fired at them as they fled on foot, killing nine.

The QF 4.5-inch howitzer was to be used for neutralising German artillery with gas shells, bombarding weaker defences, blocking communication trenches, night barrages and wire-cutting on ground where field guns could not reach. The BL 60 pounder gun was to be used for longer-range barrages and counter-battery fire, the 6-inch Gun for counter-battery fire, neutralisation-fire and wire-cutting using fuze 106. The larger howitzers were reserved for counter-battery fire against well-protected German artillery and the larger guns for long-range fire against targets like road junctions, bridges and headquarters. Co-ordination of artillery was improved by using more telephone exchanges, which put artillery observers in touch with more batteries. Observing stations were built to report to artillery headquarters located at corps headquarters, on the progress of infantry and a corps signals officer was appointed to oversee artillery communication, which had become much more elaborate.

Heavier equipment bogged in churned mud so had to be brought forward by wagons along roads and tracks, many of which were under German artillery observation from Passchendaele ridge, rather than being moved cross-country. The I Anzac Corps had 205 heavy artillery pieces, one gun for every 9 metres (9.8 yd) of front and many field artillery brigades with 18-pdr guns and 4.5-inch howitzers, which with the guns of the other attacking corps were moved forward 2,000 yd (1,800 m) from 20–24 September. Assembled forward of the artillery were heavy Vickers machine-guns of the divisional machine-gun companies, 56 for the creeping machine-gun barrage and 64 "SOS" guns for emergency barrages against German counter–attacks and to prolong the barrage towards the final objective. The frontages of VIII and IX Corps were moved northwards so that X Corps could take over 600 yd (550 m) of front up to the southern edge of Polygon Wood, which kept each of the frontages of the two Australian divisions of I Anzac Corps to 1,000 yd (910 m). The 39th Division took over from the 41st Division ready to attack Tower Hamlets (on the Bassevillebeke spur), the 33rd Division replaced the 23rd Division beyond the Menin Road and the 5th and 4th Australian divisions replaced the 1st and 2nd Australian divisions in Polygon Wood. A German attack on 25 September between Menin Road and Polygon Wood occurred as the 33rd Division was taking over from the 23rd Division and for a time threatened to delay preparations for the British operation, due next day. Some ground was captured by the Germans and part of it was then recaptured by the 33rd Division. Plumer ordered that the flank guard protecting the I Anzac Corps on 26 September be formed by the 98th Brigade of the 33rd Division while the 100th Brigade recaptured the lost ground. Plan of attack Dispersed and camouflaged German defences, using shell-hole positions, pillboxes and the holding back of much of the German infantry for counter-attacks, had meant that as British advances became weaker and disorganised by losses, fatigue, poor visibility and the channelling effect of waterlogged ground, they met more and fresher German defenders.

Large numbers of machine-guns were organised to fire offensive and defensive barrages and signal detachments were organised to advance with the infantry. An observation balloon was reserved for messages by signal lamp from the front line, as insurance against the failure of telephone lines and message-runners. The divisional trench mortar batteries were to bombard the German front line opposite the 142nd Brigade, where it was too close for the artillery to shell without endangering British troops. Wire-cutting began in mid-May, against considerable local retaliation by German artillery. At the end of May the two attacking brigades began training at Steenvoorde, on practice courses built to resemble the German positions to be attacked, using air reconnaissance photographs to mark the positions of machine-gun posts and hidden barbed wire. Divisional intelligence summaries were used to plan the capture of German company and battalion headquarters. The 140th Brigade with four tanks attached, was to occupy White Château and the adjacent part of Damstrasse, while the 142nd Brigade attacked the spoil heaps and the canal bank to the left. On 1 June, the British artillery began the intense stage of preparatory bombardment for trench-destruction and wire cutting and the two attacking brigades assembled for the attack from 4–6 June. British fighter aircraft tried to prevent German aircraft observing for their artillery, by dominating the air from the British front line to the German balloon line, about 10,000 yards (9,100 m) beyond. Better aircraft like the Bristol Fighter, S.E.5a and the naval Sopwith Triplane had entered service since Arras and matched the performance of the German Albatros D.III and Halberstadt D.II fighters.
