The Battle of Hill 70 took place in the First World War between the Canadian Corps and five divisions of the German 6th Army. The battle took place along the Western Front on the outskirts of Lens in the Nord-Pas-de-Calais region of France between 15 and 25 August 1917.
The objectives of the assault were to inflict casualties and to draw German troops away from the 3rd Battle of Ypres and to make the German hold on Lens untenable.Шаблон:Sfn The Canadian Corps executed an operation to capture Hill 70 and then establish defensive positions from which combined small-arms and artillery fire, some of which used the new technique of predicted fire, would repel German counter-attacks and inflict as many casualties as possible. The goals of the Canadian Corps were only partially accomplished; the Germans were prevented from transferring local divisions to the Ypres Salient but failed to draw in troops from other areas.Шаблон:Sfn
A later attempt by the Canadian Corps to extend its position into the city of Lens failed but the German and Canadian assessments of the battle concluded that it succeeded in its attrition objective. The battle was costly for both sides and many casualties were suffered from extensive use of poison gas, including the new German Yellow Cross shell containing the blistering agent sulphur mustard (mustard gas).
Background
Western front
By May 1917, the Nivelle Offensive, despite the successful opening of the Battle of Arras, had come to a disastrous conclusion with the French Army mutinies.Шаблон:Sfn On 30 April, as the French hesitated to continue the Second Battle of the Aisne (16 April – 9 May 1917), the commander of the British Expeditionary Force, Field Marshal Sir Douglas Haig, gave orders to the First Army (General Henry Horne), to advance towards Lens to gain a line from Méricourt to Sallaumines Hill, Lens and Hill 70. Horne already desired to cut off the salient containing Lens to shorten the front, while unwilling to risk a costly and slow frontal assault into the maze of ruins. The First Army was understrength after the Battle of Arras but since Operation Alberich, the German withdrawal to the Hindenburg Line, in March, there was some hope that the 6th Army (General Otto von Below) could be manoeuvred out of Lens by gradual advances to capture the higher ground to the south, west and north of the city.Шаблон:Sfn
On 7 May, Haig informed the British army commanders that the French had terminated the Nivelle Offensive and the strategy of returning to a war of manoeuvre. Operations to exhaust the powers of resistance of the German armies would resume by systematic, surprise attacks and when this was complete, the British would begin an offensive at Ypres to capture the Belgian coast and reach the frontier with the Netherlands.Шаблон:Sfn The objectives of the First Army were unchanged but instead of capturing ground around Lens to shorten the front, was to menace the German hold on Lens and the defences south of Lille, to divert and to weaken the 6th Army. The operations were not a diversion but a means to keep the First Army front active for as long as possible, to mislead the Germans as to British intentions in Flanders.Шаблон:Sfn On 8 May, Horne told the First Army corps commanders that
On 7 July, Haig gave orders that the Canadian Corps was to capture Lens to stop the 6th Army from sending troops north to Flanders.Шаблон:Sfn
Lens
From Vimy Ridge the ground declines about Шаблон:Cvt into the Douai Plain; the valley of the Souchez river is about Шаблон:Cvt wide and flows south-west to north-east through the south of the city of Lens. In 1914, the river had several road and rail bridges. By 1917, much of the city was derelict due to years of artillery bombardments, the ruins being natural strongpoints overlooked by Шаблон:Lang (slag heaps) and several hills, including Hill 70, Hill 65 and Sallaumines Hill forming a shallow, saucer-shaped depression in which the city lay. To the south-east, on terrain that is Шаблон:Cvt above sea level, Sallaumines Hill rises to Шаблон:Cvt. On the west side of Lens is Hill 65 (Reservoir Hill) north of the Souchez, which is steep-sided and gives a fine view of the city.Шаблон:Sfn
To the north-west, on the east side of the Lens–Bethune road, is a hill about Шаблон:Cvt high with the suburb of Cité St Pierre on top. Hill 70 is north of the city and has a flat top, giving a fine view of the city and the ground to the north and east. The hill slopes gently towards Lens and there is a shallow depression between it and Cité St Pierre. The slopes of Hill 70 towards Cité St Auguste are steeper.Шаблон:Sfn Lens, Hill 70, Sallaumines and Sallaumines Hill to the south-east and their commanding views over the area and the city, fell under German control in October 1914, during the Race to the Sea.Шаблон:Sfn In September 1915, the British overran the hill during the Battle of Loos but it was recaptured by the Germans.Шаблон:Sfn
Local operations
Horne began to make plans for the capture of Lens during the Third Battle of the Scarpe (3–4 May). Horne wanted the Canadian Corps to continue its operations east of Vimy Ridge to capture Méricourt and La Coulotte, which would endanger the German defences of Sallaumines Hill, south-east of Lens, as I Corps (Lieutenant-General Arthur Holland) north of the Souchez, with twelve tanks, captured Hill 65 (Reservoir Hill) and Hill 70. The attacks would envelop Lens on three sides and give forward observation officers (FOO) sight of the German defences in the city, potentially to force the 6th Army to retire without the need for a frontal attack. In May, Holland had surveyed the I Corps front, noted the importance of Hill 70 and that the Germans would make great efforts to re-capture it.Шаблон:Sfn
German counter-attacks could only be resisted if plenty of reserves and much artillery support were made available. Deliberate attacks to capture the high ground around Lens would meet the goals of the First Army despite its limited means.Шаблон:Sfn In May and early June, First Army units conducted eighteen raids and minor actions, moving the front line slowly eastwards over the Douai Plain. By 6 June, the First Army had captured all the high ground in the area, except that around Lens. I Corps was west of the city from the Souchez north to Hill 65 (Reservoir Hill), through Шаблон:Lang and along the ridge of the 70-metre hill to the north of Cité St Pierre.Шаблон:Sfn
On 9 June Arthur Currie, the 1st Canadian Division commander, was promoted to command the Canadian Corps.Шаблон:Sfn On 10 June, Holland told Horne that only the capture of Hill 70 was important and suggested inflicting mass casualties by raids, bombardments and gas attacks, to create the impression that a big attack was imminent. The defenders would be kept guessing and have to move more troops and artillery to the hill, despite the inevitable losses. Horne doubted that the army had sufficient men and artillery for the task and arranged for the 46th (North Midland) Division, on the right of I Corps, to make preparations to take Hill 70 and the vicinity but only if reinforcements from GHQ were forthcoming. While waiting, I Corps would capture Hill 65 and south of the Souchez, the right flank divisions of the Canadian Corps and XIII Corps to the south would prepare to attack from Gavrelle to Oppy, Fresnoy, Acheville and Mėricourt, digging jumping-off trenches to simulate a threat to Lens from the south. The real attack was to come from the left flank of the Canadian Corps towards Sallaumines Hill and the east end of Avion. Success would trap the Germans in Lens between Sallaumines Hill to the south and Hill 70 to the north. If the 6th Army did not retire, the preparations by I Corps at Hill 70 would make it impossible to predict from which direction the next attack would come.Шаблон:Sfn
Affairs south of the Souchez
To create a threat to Lens, Horne intended that XIII Corps on the southern flank would attack to reach better positions between the villages of Gavrelle and Oppy by advancing the front line for Шаблон:Cvt on a Шаблон:Cvt front. The 4th Canadian Division on the left flank of the Canadian Corps south of the Souchez River (a tributary of the Deûle) and the 46th (North Midland) Division on the right of I Corps, north of the river, were to attack on a front of Шаблон:Cvt to eliminate a German salient from Avion to the west end of Lens and to occupy Hill 65 (Reservoir Hill). I Corps was to plan for an attack on Hill 70 with the 6th Division on the left (northern) flank. Horne expected that the operations would take place in early July but found that many of the best heavy guns were to be sent to Flanders and brought forward the date to 28 June. The plans were made less ambitious; the XIII Corps scheme was retained but the attack either side of the Souchez was reduced to the capture the German front line west of Avion and Hill 65; the Hill 70 plan was postponed.Шаблон:Sfn
28 June was dull, humid and storm clouds appeared in the south during the afternoon. The First Army artillery, assisted by Third Army guns en route to Flanders, began a bombardment along the Шаблон:Cvt army front from Gavrelle northwards to Hulluch. The simulation of a much bigger attack on Lens was enhanced by lightning, thunder and a downpour, which began at Шаблон:Nowrap when the infantry advance began. The adjacent brigades of the 31st and 5th divisions had been bombarded in their jumping-off trenches at Шаблон:Nowrap and suffered 200 casualties before the advance began. The survivors moved so fast that when a German counter-barrage fell on no man's land three minutes later, the British were on the far side and suffered no harm. The attackers had few casualties, took Шаблон:Nowrap and counted Шаблон:Nowrap German soldiers. Gavrelle Mill and a new line was consolidated, despite the rainstorm, from which the areas to the north-east and east around Neuvireuil and Fresnes could be observed, along with Greenland Hill to the south-west.Шаблон:Sfn
Capture of Avion
Orders from the First Army HQ reached Currie on 12 June, who replied with a suggestion that the capture of Hill 65 was tactically desirable to gain observation over Lens and to deprive the Germans of reciprocal observation of the British rear. The capture of Avion could be replaced by a raid, to avoid the casualties of a permanent occupation. Preparations for offensive operations towards Avion would be more meaningful to German observers than the attack which followed. The suggested alternative was not well received by Major-General (Warren) Hastings Anderson, the First Army chief of staff, because one purpose of the operation was to threaten Lille, which could only occur with the capture of Lens after the attack on Avion. The Canadian operation was a stage in the army plan, to be followed by an attack or Шаблон:Lang towards Sallaumines Hill. A few days later more artillery was transferred to Flanders and the Hill 70 attack was postponed.Шаблон:Sfn
Further north, opposite the 4th Canadian and 46th (North Midland) divisions, the German 56th Division had moved into reserve on 22 June to replace a division transferred to Flanders. The line-holding division (Шаблон:Lang) had orders to retire from the salient to the Avion–Lens railway if pressed. The western slopes of Hill 65 had been occupied by the British on 24 June after a German retirement and patrols pushed forward towards Avion Trench, which was occupied early on 28 June. The 46th (North Midland) and 4th Canadian divisions made ready to resume their advance when the army barrage began at Шаблон:Nowrap Most of Avion, Éleu-dit-Leauwette and the eastern slope of Hill 65 was captured as the 3rd Canadian Division formed a defensive flank along the Arleux–Avion road, joining with the 4th Canadian Division in Avion. Rain and flooding from the Souchez stopped patrols from probing the German main line of resistance in the north-eastern part of Avion and along a railway embankment about Шаблон:Nowrap further on.Шаблон:Sfn
Prelude
First Army
The Canadian Corps had the 1st, 2nd and 4th Canadian divisions for the attack and the 3rd Canadian Division in reserve. Artillery planning was delegated to Major Alan Brooke who had two-hundred and forty 18-pounder field guns and seventy-eight 4.5-inch howitzers of the Canadian Corps field artillery, 31 of the 18-pounders being unusable due to barrel-wear. I Corps contributed twelve more 18-pounders and XIII Corps eighteen. Brooke also had 38 batteries of heavy siege howitzers consisting of twenty 9.2-inch howitzers, twenty 8-inch howitzers, eighty 6-inch howitzers, forty-two 60-pounder guns and two 6-inch guns. The British contributed 28 batteries but approximately 25 per cent of the heavy artillery for the operation was of dubious value due to barrel wear. Twenty batteries were in three Heavy Artillery Groups (HAGs) for destructive bombardment, and 18 batteries in three HAGs for counter-battery-fire, four British and two Canadian.Шаблон:SfnШаблон:Efn
6th Army
The 6th Army was responsible for the defence of the area between Lille and Cambrai, Lens being about halfway between. The town was an important railway junction and after the Battle of Arras, earlier in 1917, had become a salient in the German defences. Hill 70 and the vicinity was held by the 7th Division, part of Шаблон:Lang, the headquarters of IV Corps. (The German army had begun to use corps headquarters as territorial command units, rather than of a permanent complement of divisions, during the Battle of the Somme.)Шаблон:Sfn Lens was garrisoned by the 11th Reserve Division in Шаблон:Lang (VI Corps). In anticipation of an attack, Army Group Crown prince Rupprecht had moved the 4th Guard Division and the 220th Division into the 6th Army area in reserve. The divisions in reserve rehearsed reinforcement and counter-attacks with the two front divisions, Below having written of an expected Canadian (Шаблон:Lang) attack on 15 July.Шаблон:SfnШаблон:Efn
Plan
On 7 July, due to a lack of artillery, Currie was ordered to take over more of the line to the north and to attack the objectives west of Lens not taken by the 46th (North Midland) Division from 29 June and 2 July. In the south the Canadian Corps was to attack beyond Avion to a railway embankment, ready to advance to Sallaumines Hill. Soon afterwards, GHQ announced that more artillery would be forthcoming and Horne met the corps commanders again on 10 July; Currie wanted to make the main effort north of the Souchez, the Canadian Corps taking responsibility for the front from Avion to Hill 70. Horne agreed and on 11 July, Currie issued the first orders for the attack. The Canadian plan for 30 July used the I Corps plan for the abortive June attack as a basis; the scheduled attack to the embankment east of Avion was to go ahead, to obtain a good jumping off point for a later advance on Sallaumines Hill to mislead the defenders about preparations for an attack. From 11 to 19 July, Canadian Corps intelligence discovered that German dispositions had changed. A new third defensive line had been completed along the northern outskirts of the city, from Cinnabar Trench along Nun's Alley, Norman Trench, Hugo Trench to Bois Hugo, beyond the objectives given to Currie on 10 July. The position had three thick belts of barbed wire, a light railway for supply and eleven strongpoints with fields of fire into Commotion Trench, the final Canadian objective. The new position was judged to have become the main German defence line.Шаблон:Sfn
Hill 70 overlooked Lens and the Douai plain and Currie believed that the Germans would commit troops that they could ill-afford to lose, to regain a position that they dared not leave in Canadian possession. Artillery observers on the hill could defeat German counter-attacks with accurate artillery-fire.Шаблон:Sfn The hill was to be occupied quickly and strongpoint defensive positions were to be established around the Шаблон:Nowrap allocated to each brigade. A combination of small-arms and artillery firepower would defeat German counter-attacks and inflict as many casualties as possible.Шаблон:Sfnm The 1st and 2nd Canadian Divisions were to attack on a front of Шаблон:Cvt to a depth of Шаблон:Cvt and capture the main enemy defensive positions on the eastern (reverse) slope of Hill 70. In the first stage, the first objective of the attackers was the German front-line, the second objective (blue line) was the German second position on the crest of the hill and the third objective (green line) was the German third line, on the far slope, about Шаблон:Cvt from the start line. The 3rd Canadian Infantry Brigade of the 1st Canadian Division would attack north of Hill 70 and its 2nd Canadian Infantry Brigade would attack the summit.Шаблон:Sfn The 4th and 5th Canadian Infantry Brigades of the 2nd Canadian Division would attack the ruins of suburbs Шаблон:Lang, Шаблон:Lang and Шаблон:Lang directly south of the hill.Шаблон:Sfn
By 16 July, the 1st Canadian Division infantry had transferred from the south-west of Lens to the north-western fringe of Hill 70. On 22 July, the divisional artillery arrived and by 25 July was in position from the south of Liévin to Bully-Grenay, among mine workings, slag heaps and ruined villages, many next to light rail lines, the Canadians having inherited the preliminary work done by I Corps. Wire cutting had been going on since 11 July but there was no time for the fifteen-day preliminary bombardment laid down in the artillery plan of 11 July. On 26 July the last orders were issued and a document "Canadian Corps Scheme of Operations" by the Brigadier-General, General Staff (BGGS), Percy Radcliffe set 30 July as the date of the attack, to coincide with the Flanders Offensive. Heavy rains reduced the area to a swamp, grounded the RFC, which provided information on the progress of the bombardment, some guns were late arriving and others had too many defects to use for wire-cutting. The attack was postponed and despite the mediocre state of many of the guns, the bombardment continued into August and several creeping barrages were fired to provoke German counter-barrages and reveal German gun positions. The 15th, 50th and 2nd Canadian Heavy Artillery Group bombarded German gun positions revealed by aerial photographs, flash spotting and sound ranging, neutralization being more effective than destruction.Шаблон:Sfn
Artillery
For the Шаблон:Nowrap eighteen-pounders and forty-eight Шаблон:Nowrap were to fire a creeping barrage; the 1st Canadian Division front Шаблон:Nowrap eighteen-pounders from the 1st and 3rd Canadian divisional artilleries and thirty field guns from the British, Шаблон:Nowrap the 14th Army Brigade, Royal Field Artillery (RFA), six from the 53rd Battery and six from the 112th Battery. The 2nd Canadian Division had its Шаблон:Nowrap eighteen-pounders and another Шаблон:Nowrap Шаблон:Nowrap eighteen-pounders of the 46th (North Midland) divisional artillery, twelve 18-pounders of the 179th Army Field Brigade and another Шаблон:Nowrap the 120th, 165th and 317th batteries. All of the 4.5-inch howitzers were from the 2nd Canadian divisional artillery, making sixty Canadian and Шаблон:Nowrap guns. The attack had Шаблон:Nowrap guns and howitzers, with Шаблон:Nowrap guns and howitzers, with Шаблон:Nowrap shells, Шаблон:Nowrap and more than Шаблон:Nowrap artillery rounds. The Canadian Corps Heavy Artillery HQ had the 63rd, 64th Heavy Artillery Groups HAG) with eight siege batteries each and the Canadian Heavy Artillery Group with five, for wire-cutting and trench destruction. Barrel wear and general unreliability meant that about half of the 18-pounders could not be used in the preliminary bombardment. Шаблон:Nowrap eighteen-pounders were to fire the first layer of the creeping barrage, with the infantry advancing about Шаблон:Cvt behind. To make it harder for the German artillery to bombard the infantry by following the creeping barrage, the rest of the 18-pounders and some 4.5-inch howitzers were to fire a barrage Шаблон:Cvt further forward; 6-inch and 9.2-inch howitzers were to fire Шаблон:Cvt beyond the second barrage line.Шаблон:Sfn
The 15th, 50th and 2nd Canadian Heavy Artillery Group had Шаблон:Nowrap pieces, from 60-pounder guns to 9.2-inch howitzers and four super heavy 12-inch gun and one 15-inch howitzer. The 12-inch guns had the ammunition for eighty rounds-per-day-per-gun for fifteen days. High explosive, gas and shrapnel shells were to be fired at German gun positions revealed by RFC reconnaissance photographs and the flash-spotters and sound rangers, to kill gunners and supply horses. One report had the 6th Army artillery in nine groups of Шаблон:Nowrap half of them field guns and half of them heavy. On the eve of the attack, the counter-batteries claimed that forty of 102 German guns had been knocked out. Many of the field guns were beyond the range of Hill 70 but I Corps on the northern (left) flank and XIII Corps on the southern (right) flank were to induce German guns to reply to harassing fire. The counter-batteries were also to be used to destroy German counter-attacks and soon after zero hour, guns from the bombardment HAGs were to join in with the counter-battery HAGs against German infantry counter-attacks. Forward Observation Observers were to accompany the Canadian infantry and establish observation posts connected to the rear with telephones, wireless and visual signalling equipment to direct the artillery.Шаблон:Sfn
Gas
By 1917, gas was delivered by shell, the substances being classed as lethal, harassing and persistent; lethal types were chlorine, phosgene and diphosgene, the phosgene types having little colour or smell. Harassing gases were non-lethal and included tear gas to compel the opponents to wear their gas masks. Catching troops not wearing gas masks with a lethal concentration of gas was difficult but phosgene bombardments could cause casualties, slow the completion of tasks and tire the victims. The Canadians collected Шаблон:Nowrap 4.5-inch and 60-pounder gas shells for the operation. Before the attack, the Royal Engineers bombarded the German defences with Шаблон:Nowrap (Шаблон:Cvt) of gas fired from Livens Projectors. Two prisoners of Infantry Regiment 156 said that their companies of eighty men and 56 men had suffered between 20 and 29 gas casualties. A prisoner from Infantry Regiment 22 said that two companies had suffered 90 gas casualties.Шаблон:Sfn
Machine-guns
Sixteen companies from the Canadian Machine Gun Corps with 128 Vickers machine guns and the armoured cars of the Canadian Motor Machine Gun Brigade (CMMGB) with 32 guns, under the command of the divisions were to supplement the artillery by firing a barrage over the heads of the Canadian infantry. The harassing machine-gun fire was to impede the movement of German troops and supplies, with targets engaged by at least four guns. The Vickers guns were supplied with 20,000 bullets per gun per day, to fire day and night, to make it more difficult for German troops to repair their defences and put out more barbed wire. The cars of the CMMGB drove back and forth behind Canadian lines and from mid-July to early August fired Шаблон:Nowrap including the static guns about ten million rounds were fired before the Canadian attack. When the hill was captured, Шаблон:Nowrap guns were to be dug in, one for every Шаблон:Cvt of front, guarded by several infantry sections.Шаблон:Sfn
Royal Flying Corps
The Canadian Corps had 16 Squadron (BE2cs), 40 Squadron (Nieuport 17s) and 43 Squadron (Sopwith 1½ Strutters) RFC in support and the Sopwith Camels of 8 (Naval) Squadron, Royal Naval Air Service for high patrols over the battlefield. An advanced landing ground at Petit Sains was made ready for 43 Squadron Strutters to mount continuous, counter-attack reconnaissance patrols. Formations of three Strutters were to observe an area Шаблон:Cvt wide and Шаблон:Cvt deep, that counter-attacking German troops would have to traverse. The Strutter crews were to report their observations by wireless to the Canadian Corps and Heavy Artillery Group headquarters, then attack with their machine-guns any German artillery or concentrations of troops seen at bottlenecks. Contact patrols to mark the progress of the Canadian infantry were to be flown by the B.E.2c crews of 16 Squadron.Шаблон:Sfnm
On 9 August, six 40 Squadron Nieuport 17s made a low-level attack on the six German observation balloons along the Hill 70–Lens front and shot them down. German artillery observation was obstructed but the attack made the Canadian interest in the area obvious. For the two days and nights before the attack, 10 Squadron, 25 Squadron (DH.4) and 27 Squadron (Martinsyde Elephant) bombed railway junctions, airfields and billets. In earlier battles, British fighters patrolling at height to engage German fighters had not been able to see low-flying, camouflaged German aircraft, which flew artillery-observation and ground attack sorties without interference. Six Nieuport 17s of 40 Squadron moved to an advanced landing ground at Mazingarbe, about Шаблон:Cvt behind the front and a ground station was established on the heights west of Loos. When observers spotted a German aircraft at low altitude, a wireless message was sent to Mazingarbe for a Nieuport 17 to be sent up to engage the German aircraft. A letter-code on white canvas sheets containing the location of German aircraft could be laid on the ground for an airborne fighter pilot to read.Шаблон:Sfn
Deception operations
By 16 July, the Canadian Corps had redeployed for the attack on Hill 70; the 1st Canadian Division had taken over from I Corps to the north-west of the hill, and the Canadian Corps occupied a line from the Souchez River northwards to just beyond Hill 70. To deceive the Germans about the place and size of the attack and to disguise Canadian preparations, the XIII, Canadian, I and XI, corps began to conduct larger raids in battalion strength, on most nights from the middle of July, along with gas discharges along the front. Towards the end of the month, raids and bombardments on the army front increased, XI Corps to the north raided nightly, I Corps conducted destructive and wire-cutting bombardments at night and bombarded the German front with machine-guns and mortars during the day; XIII Corps conducted similar operations on the right (southern) army flank.Шаблон:Sfnm
In late July, the 9th Canadian Brigade feinted a direct attack of Lens by engaging units of the German 36th Reserve Division at Méricourt Trench.Шаблон:Sfnm Bad weather led to the attack on Hill 70 being postponed from late July until mid-August. In the interim, special companies of the Royal Engineers augmented the regular level of bombardment by firing Шаблон:Nowrap drums from Livens projectors and Шаблон:Nowrap shells into Lens by 15 August. The artillery neutralized Шаблон:Nowrap of an estimated Шаблон:Nowrap batteries in the area by zero hour, partly using the technique of predicted fire using datum points and calibrated guns for the first time, which greatly improved the accuracy of the artillery.Шаблон:Sfn Troops were rotated through the reserve area to conduct training and rehearsals in preparation for the assault.Шаблон:Sfn On the northern (left) flank, the 46th (North Midland) Division made a diversionary attack north of the hill, with poison gas discharges, artillery bombardments and the preparation of dummy tanks and troops on the two nights before the attack to be exposed to view at zero hour.Шаблон:Sfn
Battle
15 August
During the night of Шаблон:Nowrap the Canadian infantry assembled in their jumping-off points; harassing fire from German artillery continued but with no particular intensity.Шаблон:Sfn The Germans had moved up reserves on the previous night in anticipation of an attack and the main assembly of Canadian troops was detected by Шаблон:NowrapШаблон:Sfn At Шаблон:Nowrap the Canadian creeping barrage began and the infantry advanced, some troops having left their trenches early to avoid the German counter-barrage expected as soon as the attack began. At Шаблон:Nowrap Special Companies RE fired Шаблон:Nowrap of oil from Livens projectors, which dropped into the German defences in Cité St Élisabeth, creating a smoke-screen and began an hour-long smoke bombardment from 4-inch Stokes mortars.Шаблон:Sfn Artillery Forward Observation Officers moved forward with the infantry and artillery-observation aircraft flew overhead sending Шаблон:Nowrap for artillery fire by wireless that day.Шаблон:SfnШаблон:Sfn
In the 1st Canadian Division area, 4 Special Company RE fired mortars and Livens projectors against the left flank of the attack, as a deception and to shield the attack front from observers on higher ground several miles to the north. On the right (southern) flank in the 4th Canadian Division area, a Special Company used Livens projectors to fire Шаблон:Nowrap cylinders into German positions around Avion.Шаблон:Sfn After four minutes, the creeping barrage began to move in Шаблон:Cvt increments, keeping about 25 per cent of the ground to be crossed under bombardment. Vickers gunners fired a machine-gun barrage at maximum range then gradually fired shorter towards the German positions. The Canadian infantry reached the blue line, Шаблон:Cvt forward in twenty minutes and paused to dig in. The advance began again and reached the final objective (red line) at Шаблон:Nowrap German resistance was determined and the Canadians used Lewis guns to pin down the German infantry as rifle and bombing sections attacked from a flank. On the southern (right) flank, the 4th Canadian Division diversion succeeded and with fewer guns in support, the German artillery reply was more effective than further north. The 12th Canadian Infantry Brigade anticipated the German artillery bombardment and the Canadians took cover in deep shelters in the edge of Lens, the brigade suffering fewer than 24 casualties during the first day.Шаблон:Sfn
The four attacking Canadian brigades began to consolidate as soon as they reached their objectives and each brigade emplaced 48 Vickers guns in its section of the blue line. Connexions to the artillery were established by observers with field telephones, wireless and signal lamps and the artillery changed from bombardment and creeping barrage fire to be ready to fire SOS barrages against German counter-attacks. At about Шаблон:Nowrap the 4th Guard Division began the first German attack, having been seen assembling in Cité St Auguste. The Germans had to move over about Шаблон:Cvt of open ground and the Canadian gun-, machine-gun and rifle fire covered the ground with corpses and wounded. An attack at Шаблон:Nowrap met the same fate, the few Germans reaching the Canadians being bombed out. German counter-attacks continued and the German artillery still in action tried to support the attacks and shell the Canadian defences. A counter-attack at Шаблон:Nowrap was prepared by German heavy artillery, which cut many of the field telephone links to the Canadian artillery but some remained operational and several runners got through with messages. The 2nd Canadian Division artillery received the message "Please turn Artillery on." and did, repulsing the attack; the Canadian gunners did the same to another German attempt at Шаблон:Nowrap Canadian machine-gunners fired all day, seven guns of the 3rd Canadian Machine Gun Company firing Шаблон:Nowrap in a few minutes.Шаблон:SfnШаблон:Efn
Air operations
The Sopwith Шаблон:Frac Strutters of 43 Squadron received many hits from ground fire but only two were shot down, three crew being wounded; a German aircraft was shot down and others driven off but four more Sopwith Шаблон:Frac Strutters were too badly damaged to be serviceable for 16 August. One Sopwith attacked troops in Drocourt Trench, another aircraft attacked a transport column near Fouquières, then troops near Annay and in Шаблон:Lang. About Шаблон:Nowrap infantry behind Шаблон:Lang, north of Lens, were strafed, then the information was reported from Mazingarbe to the Canadian Corps heavy artillery, which dispersed the German troops. While flying artillery-observation sorties in the afternoon, 16 Squadron aircrew saw four waves of German infantry advancing in the open to counter-attack. The crews called on the Canadian heavy artillery and then attacked with their machine-guns, which "all but annihilated" the German force.Шаблон:Sfn From 15 to 17 August, the RFC sent Шаблон:Nowrap of German artillery in action and all were answered by the counter-battery groups.Шаблон:Sfn
Counter-attacks
To prepare for German counter-attacks, the 1st and 2nd Canadian Divisions began to reverse captured trenches and construct strong points immediately after capturing the blue line. Within two hours of the start of the battle, the Germans began using their immediate reserves to mount local counter-attacks (Шаблон:Lang). Between Шаблон:Nowrap on the morning of 15 August, the Germans executed four local attacks against Canadian positions. Each attack was repulsed due in large part to the work of forward artillery observers, who could now overlook some of the German positions. On one occasion, a German counter-attack was only repulsed after engaging in hand-to-hand fighting. The Germans rapidly brought up seven additional battalions from the 4th Guards Division and 185th Division to reinforce the eight line battalions. Over the following three days, the Germans counter-attacked 21 times against Canadian positions.Шаблон:Sfn A frontal attack against the 2nd Canadian Infantry Brigade on the afternoon of 15 August ultimately failed. A German attack against the 4th Canadian Infantry Brigade re-captured Chicory Trench but the German infantry were expelled later that afternoon.Шаблон:Sfn
16–17 August
The morning of 16 August was relatively quiet, with only a few attempts made by small German parties to approach the Canadian lines. After having failed to capture all their objectives the previous day and after several postponements, the 2nd Canadian Infantry Brigade relieved the two attacking battalions with the 5th and 10th Canadian battalions, which attacked by short dashes for Шаблон:Cvt down the bare slope and captured the remainder of the final objective. The attack was costly as the Germans opposite were preparing their own counter-attack and hand-to-hand fighting took place at the chalk quarry, which cost the Germans 100 fatal casualties, 100 wounded and thirty prisoners. The Germans began to counter-attack at Шаблон:Nowrap after a delay but good observation enabled the attacks to be repulsed by massed artillery-, machine-gun and rifle-fire. To the south, the 5th Canadian Battalion retired from the final objective for about Шаблон:Cvt to shell-holes, after suffering many casualties and running short of ammunition. The brigade suffered casualties of Шаблон:Nowrap killed, Шаблон:Nowrap wounded and Шаблон:Nowrap missing.Шаблон:Sfnm
Attempts by the 4th and 11th Canadian Infantry Brigades to eliminate a German salient between Cité St Élisabeth and Lens on 17 August failed and as had been foreseen, the Germans continued to mount determined counter-attacks. The German commanders realized that the Canadian and British artillery would need to be neutralized before a counter-attack could succeed. The Germans began a series of counter-attacks against a chalk quarry under Canadian control outside Cité St. Auguste and tried to mislead the Canadian artillery by sending up false flare signals or provoking the infantry to call for unnecessary artillery fire.Шаблон:Sfn The Germans stopped wave attacks and counter-attacked with dispersed groups of troops trickling forward using cover; some managed to reach the Canadian defences and fight hand-to-hand.Шаблон:Sfn The Germans began to use poison gas in earnest and from 15,000 to 20,000 of the new Yellow Cross shells, containing the blistering agent sulphur mustard, were fired in addition to Green Cross (diphosgene) shells. The positions of the 1st and 2nd Canadian Artillery Field Brigades and the Canadian front line were gassed. The 1st Canadian Division artillery suffered 183 casualties and three batteries suffered direct hits. Many gunners became casualties after gas fogged the goggles of their respirators and they were forced to remove them to set fuses, lay their sights and maintain accurate fire.Шаблон:Sfnm
17/18 August
On the night of Шаблон:Nowrap German troops made several attempts to recapture the chalk quarry and Chicory Trench under the cover of gas. All attempts against the chalk quarry failed and only one company of the Reserve Infantry Regiment 55 (on loan to the 11th Reserve Division) managed to breach the Canadian defences at Chicory Trench before being repulsed. German troops employing flamethrowers managed to penetrate the Canadian line north of the quarry on the morning of 18 August before being driven out.Шаблон:Sfn
19–20 August
The front quietened significantly after the final counter-attack against the chalk quarry. For the Canadian Corps, the following two days consisted largely of consolidation. The front line was drawn back Шаблон:Cvt, midway between the original intermediate and final objectives. The 4th Canadian Division slightly advanced its forward posts on the outskirts of Lens and extended its front northward to include the Lens–Béthune road. Currie wished to further improve the position around Hill 70 and ordered an attack against German positions along a Шаблон:Cvt front, opposite the 2nd and 4th Canadian Divisions.Шаблон:Sfn
21–22 August (Attack on Lens)
The operation was scheduled for the morning of 21 August, the tasks being divided between the 6th Canadian Infantry Brigade on the left and the 10th Canadian Infantry Brigade on the right. The attack was to begin at Шаблон:Nowrap but the Germans began shelling the Canadian positions at Шаблон:Nowrap Just before the Canadian attack, the left flank of the 6th Canadian Infantry Brigade was attacked by units of the 4th Guard Division and a battalion of the 220th Division. The forces met between their objectives and fought hand-to-hand and with the bayonet; in the Шаблон:Lang the 6th Canadian Infantry Brigade advance was stopped and the troops forced back to their start line. Communication between the forward units and brigade headquarters had broken down at the beginning of the attack and could not be restored due to the German bombardment, making it all but impossible to co-ordinate the infantry and artillery.Шаблон:Sfn
On the right flank, a battalion of the 10th Canadian Infantry Brigade suffered many casualties to the German artillery while assembling for the attack and was met with massed artillery and machine-gun fire, near its objective. Only three small parties, the largest of not more than twenty men, reached their goal. The other two attacking units captured their objectives late in the evening, creating a salient in the 4th Canadian Division line. On the evening of 21 August, three parties went forward to bomb the German position from the flanks but were only moderately successful and an attack on 22 August failed to materialize, due to battalion-level misunderstandings. A brigade reserve unit was ordered to remedy the situation by attacking the Green Crassier slagheap and the mine complex at Fosse St Louis. The attack was repulsed, most of the attackers being killed, wounded or taken prisoner. The Germans held on to the area until the beginning of the final German retreat in 1918.Шаблон:Sfn
Aftermath
Analysis
On 15 August, Haig made a diary note that the attack had gone "very well"; Horne called it "an unqualified success", despite the failure of the 6th Army to retreat and began to plan an attack on Sallaumines Hill for early September.Шаблон:Sfn In 1942, the writers of Шаблон:Lang, the German official history (volume XIII), wrote that since mid-July, the German defences at Lens and for about Шаблон:Cvt to the north had been under bombardment, which became more intense in August because Haig wanted a diversion from the offensive in Flanders. On 15 August, the Canadian Corps attacked the German positions from Lens to about Шаблон:Cvt north, took an important height [Hill 70] for observation and pushed beyond the First Position (Шаблон:Lang). Counter-attacks recaptured pockets of ground but the Canadians could not be expelled from Шаблон:Lang. Fighting continued intermittently until 24 August but did not lead to more significant changes. The Canadians took over Шаблон:Nowrap and in their counter-attacks the Germans over Шаблон:Nowrap prisoners.Шаблон:Sfn
In 1981, Sydney Wise, author of the Royal Canadian Air Force official history, called the attack at Hill 70 "a demonstration of how a set-piece attack should be carried out".Шаблон:Sfn The Germans refrained from attempts to recapture the lost ground at Lens, due to the need to avoid diverting resources from the Third Battle of Ypres in Flanders, the main strategic effort on the Western Front by both sides.Шаблон:Sfn In 2009, Tim Cook wrote that the Canadian attack had crushed the defenders by 18 August, 21 German counter-attacks being repulsed. The Canadian plan had succeeded but had depended on the determination of the Canadian infantry against equally determined opponents, who suffered approximately Шаблон:Nowrap against Шаблон:Nowrap The attack ended on 25 August and was a considerable victory despite the Germans retaining their hold on occupation of Lens. Two German divisions intended for Flanders had been diverted to Hill 70 and the reinforcement plan for the fighting at Ypres had been dislocated. Cook called the battle the most one-sided German defeat apart from the Battle of Messines in June. The attacks into Lens had been "clumsy, hurried affairs" and that the Canadians suffered nearly Шаблон:Nowrap from 21 to 25 August. The frontal attacks on 21 and 23 August were rash and demonstrated that Currie lacked experience; Cook placed blame on Watson and Hilliam, the latter of whom should have been sacked.Шаблон:Sfn
In 2016, Robert Foley wrote that Army Group Crown Prince Rupprecht and the 6th Army headquarters thought that the Canadian advance had been stopped by 16 August. Below wrote in his diary that more than ten attacks by the Canadians, "the best Шаблон:Sic troops", had been repulsed. The Canadian attack had been stopped because the "English" lacked the flexibility to exploit success, a criticism that had emerged during the Battle of the Somme in 1916.Шаблон:Sfn The Canadian attack was seen as a feint to divert German divisions from Flanders and the army group ordered the 6th Army to fight with its own resources, including the seven divisions in army reserve. The 4th Guard and the 220th divisions acted as Шаблон:Lang on 15 August and with the existing divisions, conducted most of the German defence. Once the German counter-attack in 15 August had failed, the attempt to recapture Hill 70 was abandoned and counter-attacks were restricted local efforts to repulse Canadian attacks and for tactical improvements to the German defences. Two divisions were moved from reserve to replace the 4th Guard and the 220th divisions, three more divisions in reserve remaining available to the 6th Army. No forces were transferred to Lens from Flanders or anywhere else and no divisions were sent to Flanders from 15 to 25 August. Foley wrote that the 1st Guard Reserve Division had been included in some accounts but that neither Below or other German sources from the time refer to it; Foley also wrote that Canadian sources mention the 185th Division in interrogation reports.Шаблон:Sfn In 2017, Andrew Rawson wrote that the Canadian attack prevented the Germans from transferring five divisions in the Lens area to Flanders.Шаблон:Sfn
Casualties
Around 22 August, the First Army intelligence department estimated that the Germans had suffered Шаблон:Nowrap casualties.Шаблон:Sfn In the History of the Great War (1948), the British official historian, James Edmonds wrote that from 15 to 23 August, the 1st Canadian Division suffered Шаблон:Nowrap, Шаблон:Nowrap The Second Canadian Division suffered Шаблон:Nowrap Шаблон:Nowrap being killed and the 4th Canadian Division had Шаблон:Nowrap including Шаблон:Nowrap Corps troops and other troops attached to the 1st Canadian Division suffered Шаблон:Nowrap a total of Шаблон:Nowrap Шаблон:Nowrap troops were taken prisoner.Шаблон:Sfn In the Canadian Official History (1962), G. W. L. Nicholson wrote that the Canadians and attached troops suffered Шаблон:Nowrap In Surviving Trench Warfare (1992) Bill Rawling wrote that the attack on Hill 70 cost the Canadian Corps Шаблон:Nowrap Шаблон:Nowrap Шаблон:Nowrap and Шаблон:Nowrap prisoner. In the subsequent attacks into Lens, the Canadian Corps suffered another Шаблон:Nowrap increasing the number to Шаблон:Nowrap in eleven days.Шаблон:Sfn
In 2009, Tim Cook wrote that the Canadians suffered Шаблон:Nowrap during the preparations for the attack in the first two weeks of August and Шаблон:Nowrap from 15 to 25 August, Шаблон:Nowrap Hill 70 and another Шаблон:Nowrap on the Western Front. The Canadians had suffered nearly Шаблон:Nowrap their casualties from 21 to 25 August. Шаблон:Sfn In Capturing Hill 70 (2016, eds. Douglas Delaney and Serge Durflinger) Delaney wrote that Tim Cook had remedied a mistake in the Canadian official history which gave Canadian Corps casualties for August rather than for the period 15 to 25 August. In 2016, Robert Foley wrote that German casualties were difficult to measure, the German official history (Der Weltkrieg) volume noting that complete records did not exist. The 7th Division suffered about Шаблон:Nowrap before being withdrawn on 17 August, the 4th Guard Division about Шаблон:Nowrap 15 to 21 August and that the 220th Division also suffered many casualties, Reserve Infantry Regiment 99 losing Шаблон:Nowrap in four days. Foley estimated that the Germans suffered Шаблон:Circa casualties; Delaney and Durflinger wrote that the lower estimates of German casualties were higher than those of the attackers, an unusual occurrence in the war.Шаблон:Sfnm
Subsequent operations
From the rest of August to the beginning of October the front was relatively quiet, with Canadian efforts devoted mainly to preparations for another offensive, although none took place, largely because the First Army lacked sufficient resources for the task.Шаблон:Sfn The Canadian Corps was transferred to the Ypres sector in early October in preparation for the Second Battle of Passchendaele.Шаблон:Sfn Soon after the battle, Below was transferred to the Italian front, where he took command of the new Austro-German 14th Army. In this capacity, he executed an extremely successful offensive at the Battle of Caporetto in October 1917. Шаблон:Lang Ferdinand von Quast took over command of the 6th Army until the end of the war.Шаблон:Sfn
