The Battle of the Ancre 13–18 November,^{[Note 1]} was the final large British attack of the Battle of the Somme in 1916, before the winter weather forced a pause in British attacks until the new year. It was fought by the Fifth Army,^{[Note 2]} under the command of Lieutenant General Hubert Gough, against the German First Army under General von Below.

The intent of the British attack was to fulfill complementary objectives. Political discontent in London would be muted by a big victory, as would doubts of British commitment by its allies; British loyalty to the Chantilly strategy of 1915 would be seen to be upheld and the capture of Beaumont Hamel and Serre would go some way to redeem the failure of 1 July and obtain ground on which the British would have a tactical advantage. The attack was the largest in the British sector since September and had a seven-day preliminary bombardment, which was twice as heavy as that of 1 July. Beaumont Hamel, St. Pierre Divion and Beaucourt were captured, which threatened the German hold on Serre further north.^{[Note 3]} Four German divisions had to be relieved due to the number of casualties suffered and over 7,000 German troops were taken prisoner.

Background

Tactical developments

After meeting with Lieutenant-General Sir Henry Rawlinson the Fourth Army commander and Gough, General Sir Douglas Haig commander of the British Expeditionary Force (BEF) cancelled the Third Army operation planned in September, on 17 October and the Reserve Army attack was reduced from a converging attack towards the Ancre river, to an attack up the valley on 23 October. The failure of the Fourth Army attack of 18 October caused another revision of the plan, the Reserve Army was to capture the rest of Thiepval Ridge with II Corps on 21 October, the Fourth and French Sixth Army to attack on 23 October and the reduced Reserve Army attack on both sides of the Ancre to begin on 25 October. Gough had issued a new operation order on 15 October and began another reorganisation on the north side of the Ancre. The II Corps operation on 21 October was successful but the rains returned on 24 October. The main attack postponed to 25 October was then cancelled, Gough being given discretion to continue to postpone the attack by Haig. On 27 October Gough set 1 November as the provisional date, postponed it again on 29 October to 5 November and on 3 November Haig gave Gough the choice of cancelling the attack and resuming operations when the weather had improved. On 5 November Haig suggested a subsidiary attack, if the state of the ground justified the effort. Gough proposed an attack on 9 November but preferred to delay. Haig agreed that there should be no attack, until the ground was dry enough for infantry to move freely and there was a forecast of two days of fair weather. Another postponement followed.^[17]

On 3 November, Major-General Rudolph Cavan the XIV Corps commander wrote to Rawlinson the Fourth Army commander, objecting to the renewal of attacks on Le Transloy, having lost 5,320 casualties already. Rawlinson informed Haig that he was going to limit the next attack, which led to a conference at Fourth Army headquarters on 4 November attended by Haig and General Ferdinand Foch. Haig explained that the Fourth Army would be attacking at other points on 5 November and Cavan agreed to make certain that the French left flank was protected. On 6 November Rawlinson announced that the Fifth Army operation due in the Ancre valley had been reduced and that the Fourth Army would conduct "modified operations" intended to stop the Germans moving troops from France. Apart from attacks near Saillisel, the French Sixth Army began to consolidate for the winter.^[18]

After another discussion on 8 November at the Fifth Army headquarters by Lieutenant-General Kiggell, Haig's Chief of the General Staff and Gough, a meeting between Gough and the corps commanders decided that the attack should begin on 13 November, if the weather stayed dry. Opinion among divisional and brigade commanders varied on the possibility of an attack and that it should go ahead or be cancelled rather than be postponed again; patrols were sent out frequently to report on the state of the ground. On 10 November Gough set the attack for 5:45 a.m. on 13 November. After studying the Fifth Army plans, Haig allowed the attack to go ahead. Gough later arranged with the corps commanders that operations towards Pys and Irles would begin if the attack on 13 November went well but avoided detail, due to the uncertain weather.^{[6][Note 4]} On 15 November Gough was visited again by Lieutenant-General Kiggell, to discuss the end of the offensive. After consultations with his subordinates, Gough asked for permission to continue for two more days, (weather permitting) which was given that evening. By the morning of 16 November Gough had heard that Munich and Frankfort Trenches were still held by the Germans and that casualties had been higher than hoped. Attacks against Serre were abandoned and the main effort was made on 18 November by II Corps by pushing down towards the south bank of the Ancre. V Corps on the north bank was to provide flank support by capturing Frankfort Trench, advancing along Ancre Trench and taking Bois d'Hollande. The attack was delayed until 18 November to be certain that preparations were complete.^[19]

Prelude

British offensive preparations

To be ready for the big attack intended for 12 October, Gough began to concentrate more troops in the area north of the Ancre. In early October the north bank was held by the 39th Division of V Corps up to the boundary with the Third Army at Hébuterne. On 1 October the 2nd Division was moved in on the left of the 39th Division to hold the ground from Redan Ridge to the army boundary. On 4 October the XIII Corps headquarters was brought out of reserve, to control 1,500 yards (1,400 m) of the front line up to the junction with the Third Army and the 2nd Division was relieved on the left by the 51st Division.^[20] The 39th Division was transferred to the command of II Corps on 2 October and then took over the area south of the Ancre on 5 October, by extending its right boundary to relieve the 18th Division at Thiepval. By 7 October XIII Corps had the 51st and 19th Divisions in line and on 8 October, V Corps relieved the 2nd Division with the 3rd and 63rd divisions. Gough issued instructions for the attack on the north bank from 4–12 October and arranged for the 1st and 3rd Cavalry divisions to move close to the front line. The artillery of V Corps and XIII Corps steadily bombarded the German defences on the south bank where II Corps operations against Staufen Riegel ("Regina Trench" to the Canadians at the east end and "Stuff Trench" to the British at the western end, north of Thiepval) and conducted a simulated offensive with artillery bombardments, wire-cutting and smoke screens.^[21]

The British front line north of the Ancre had been moved forward across no-man's-land, until the average width was less than 250 yards (230 m). It was intended to isolate the battlefield with artillery and bombard Pys, Irles, Miraumont and Puisieux and the main trenches leading to the battlefield. On the II Corps front, artillery fire was to simulate an attack on the ground east of the old German second line ("Grandcourt line") as would XIII Corps artillery on the German approaches to the northern flank.^{[22][Note 5]} Slow progress on the south bank by II Corps, attempting to occupy Regina Trench, caused by a serious deterioration in the weather and determined defence by the Germans of the remainder of their positions on the ridge north of Courcelette and Thiepval, caused numerous postponements of the general attack on both sides of the Ancre. Haig's plans made at the end of September, were reduced to achieving as much as could be done in periods of better weather. Conditions on the battlefield by mid-October were "so bad as to make mere existence a severe trial of body and spirit".^[23] On 12 November Beaumont Hamel was subjected to a gas bombardment, similar to one on 28 October, when "sk" (lachrymatory) mortar bombs were fired into the village at midday, to wear out the German garrison's respirators and then in the evening phosgene was fired by Livens Projector to kill them.^[24]

British plan of attack

Gough planned to attack on 13 November, with five divisions from II and V Corps astride the Ancre river, which flowed between Thiepval and Beaumont Hamel.^{[Note 6]} Gough intended to reduce the head of the German salient between Thiepval and Serre, the main effort coming from V Corps with the 63rd, 51st, 2nd and 3rd divisions against positions north of the Ancre, which had not been seriously attacked since the opening of the Somme offensive on 1 July. It was hoped that the intervening nineteen weeks of trench warfare had substantially reduced German fighting power.^[25] Three objective lines were set, the first running from Beaucourt Station (opposite St Pierre Divion)–up Beaumont Hamel valley–eastern outskirts of Beaumont Hamel–Redan Ridge–west of Serre, requiring an advance of 800 yards (730 m) over three German trench lines and four trench lines in places. The second line was 600–1,000 yards (550–910 m) further forward, running west of Beaucourt–east slope of Redan Ridge–east of Serre–west to the boundary of V and XIII Corps, which would be advanced towards Star Wood. The final objective (third line) was set at Beaucourt–the Puisieux road valley–second line. II Corps with the 4th Canadian, 18th, 19th and 39th divisions was to advance from Stuff trench and Schwaben Redoubt to the Hansa line to force the Germans out of their defences, from Schwaben Redoubt–St Pierre Divion, as far back as Beaucourt, securing the road bridges by Beaucourt station and Beaucourt mill by 7:25 a.m.^[22]

The V Corps bombardment was intended to create tactical surprise, by the heavy artillery firing on the German front line thirty minutes before dawn each morning, for an hour of intense fire joined by the field artillery. It was hoped that the German garrisons would become accustomed to the routine and not react, when the opening bombardment for the attack began at 5:45 a.m. No man's land 50 yards (46 m) back from the front trench was to be bombarded by 25% of the 18-pdrs, to cover the infantry as it advanced from the British line. After six minutes the bombardment would creep forward at 100 yards (91 m) in five minutes, pausing on the reserve line of the German front trench system before moving on. The infantry had 56 minutes to reach the first objective and then move on after a pause of an hour. After five minutes of silence a lifting bombardment beginning with intense fire, would signal the infantry to begin their advance. The attack by the 63rd Division on Beaucourt was to begin 200 minutes after zero, preceded by a bombardment from all available artillery.^[22] A few tanks were available and the bombardment was twice the weight of that before 1 July. A machine-gun barrage (first tried at the Battle of Thiepval Ridge, 26–30 September) was to be laid on the German machine-guns dug in along the ridge behind Beaumont Hamel.^[26]

Air reconnaissance reports late in the afternoon of 17 November indicated that the Germans had abandoned Puisieux Trench and the Grandcourt line south of the river. Gough ordered both corps commanders to send patrols and occupy the trenches if possible. New orders were issued, extending the objectives for the attack planned for 18 November. The new plan for 18 November allowed II Corps a halt of 90 minutes on the first objective, then the 19th Division would attack Grandcourt and Baillescourt Farm. The 4th Canadian and 18th divisions would then advance and take Grandcourt Trench to link with the 19th Division at the east end of Grandcourt. II Corps was then to cross the Ancre to take Baillescourt Farm. V Corps was to synchronise its advance to Pusieux Trench and River Trench up to Artillery Alley on the north bank of the Ancre. Lieutenant-General Claud Jacob the II Corps commander protested against the plan and was overruled, despite patrols from the 19th Division finding Germans repairing the wire of the Grandcourt line.^[27]

German defensive preparations

Agents warned the German command by 12 October, that an offensive was looming on the Ancre. By 2 November General von Below, commander of the First Army reported that he expected an attack between the Ancre and Gommecourt and that there were signs that British attacks further east were over for the year. On 21 October Crown Prince Rupprecht, the army group commander favoured withdrawal from St Pierre Divion and Beaumont Hamel but the First Army commander took a more tactical view, pointing out that withdrawal would forfeit observation from the high ground and that no positions behind the line were better placed. The 12th Division was brought in between the 38th Division at Beaucourt and the 52nd Division at Serre on 22 October. The French attack at Verdun on 24 October dislocated reliefs on the Somme but British pressure forced the replacement of the seven divisions from Le Transloy to the Ancre from 24 October – 10 November, then the relief of one of the replacement divisions.^{[12][Note 7]}

After the German recapture of La Maisonette on 29 October, counter-attacks against the French at Sailly-Saillisel and elsewhere were cancelled, yet there were no reinforcements for the 12th Division in the Ancre sector. A "fresh" regiment of the 12th Division took over at Beaumont Hamel 26–27 October despite being understrength, its companies only having 80–90 men; by 10 November it had another 175 casualties. Constant shelling and wet weather exhausted the German troops and cut off the flow of supplies until 11 November, when the British shellfire eased. On 6 November Below and Lossberg the First Army Chief of Staff, concluded that the Ancre–Serre salient was too dangerous, due to artillery fire from the flank and rear and Below contemplated a withdrawal to Lesboeufs.^[12] The rain stopped on the night of 11/12 November and a full moon illuminated the landscape. Towards dawn a mist developed which reduced observation to nil.^[28]

13 November The seven-day bombardment cut the wire on most of the attack front and destroyed many German defensive positions, except the dugouts built deep below the villages near the front-line. Mist on 13 November helped the British advance by reducing visibility but caused many British units to lose the barrage as they struggled through mud.^[30] II Corps attacked on the right with 19th Division. A battalion from the 58th Brigade made no progress against Stump Road; the 56th Brigade attacked on the right by assembling in no man's land before Stuff Trench, with a machine-gun company attached and followed up by Engineer and Pioneer parties, ready to help consolidate captured ground. The mist helped conceal the British troops, who by 8:15 a.m. had reached their objective, partly along Lucky Way, a sunken road leading into Grandcourt. No German counter-attacks were encountered^[31]

The 39th Division attacked to the west of the 19th Division, with the 118th Brigade on its right. The brigade formed up on tapes laid without the German sentries noticing and one battalion advanced north about 1,100 yards (1,000 m) to the Hansa line by 7:30 a.m., while three battalions attacked north-west to Mill Trench and then reached the station crossing and Beaucourt Mill by 10:00 a.m.. The other two battalions got lost in the fog. At 6:15 a.m. the 117th Brigade attacked from Mill Road up the Ancre valley, next to the river with one battalion and achieved surprise, despite a special barrage firom twelve 18-pdrs. The battalion cleared dugouts in the side of the river bank and along the top. The battalion met some of the troops of 118th Brigade, who were lost and combined to attack St Pierre Divion, which was captured around 7:40 a.m. Three tanks were to advance from Thiepval to assist but one was bogged on the drive to the village, the second broke down and the third reached the German front line at 7:00 a.m. then fell into a dug-out, where it was attacked by the Germans. A messenger pigeon was sent by the tank crew for help but infantry arrived at 9:00 a.m. and the Germans withdrew.^[32]

In V Corps, two 63rd Division brigades each advanced with all four battalions forward and two in support from the reserve brigade. On the right the advance met much German machine-gun fire from the start but captured the German front trenches, then advanced on time to take Beaucourt station and Station Road, taking 400 prisoners by 6:45 a.m. The two battalions on the left were severely depleted by machine-gun fire, as was the left brigade although about 100 men reached the first objective. On the extreme left only isolated groups managed to advance, where they met troops from the 51st Division. The left brigade began bombing attacks and the reserve brigade was sent forward. By 7:40 a.m. troops were digging in along the German reserve line in the south, while three battalions were held up along the German front line, although some of their troops appeared on the Beaumont Hamel spur. At 7:45 a.m. about 450 men advanced to the edge of Beaucourt, before withdrawing slightly and digging-in under artillery fire, before gaining touch with troops from the 39th Division from across the river. The German strongpoint on Beaumont Hamel spur was attacked many times but little ground was gained. As night fell the division had linked with the 51st Division on the left in the German support trench. Reinforcements from the reserve brigade and an extra battalion reached Beaucourt and extended the position to the left as far as Beaucourt Alley by 9:30 p.m.. Two battalions reached the first objective by midnight and a battalion took over the British front line.^{[33][Note 8]}

Both brigades of the 51st Division attacked the first objective (green line) at Station road and Beaumont Hamel and the final objective (yellow line) at Frankfort Trench with three battalions, while the fourth provided carrying parties.^[34] Six minutes before zero, the leading battalion of the right brigade moved beyond the British wire and advanced, when the new 30,000 pounds (14,000 kg) mine at Hawthorn Crater was blown, past the east end of "Y Ravine" and reached the first objective at 6:45 a.m., with a stray party from the 63rd Division. The battalion pushed on then withdrew slightly to Station Road. On the left, fire from '"Y Ravine" held up the advance and at 7:00 a.m. another battalion reinforced the attack. Troops skirted the ravine to the north and early in the afternoon a battalion from the reserve brigade attacked Beaumont Hamel from the south, joined by troops in the vicinity. The left brigade was held up in places, by uncut wire south of Hawthorn Crater and massed machine-gun fire north of the Auchonvillers–Beaumont Hamel road. Two tanks were sent up, one bogging between the German front and support lines and the other north of the village. Consolidation began and three battalions were withdrawn to the German reserve line and reinforced at 9:00 p.m., while one battalion formed a defensive flank to the south, as the positions reached by the 63rd Division were unknown.^{[Note 9][35]}

The 2nd Division advanced along Redan Ridge. The 5th Brigade on the right formed up in no man's land, hugged the barrage and got into the German front line easily. Two battalions reached Beaumont Trench on schedule and the other two formed a defensive flank facing north and repelled bombing attacks from the 6th Brigade area, where the advance had been held up by fog and mud, then fire from "The Quadrilateral" in the middle of the 6th Brigade area, where some troops on the right managed to reach the first objective. The junction of Beaumont Trench and Lager Alley was blocked and some troops veered north-east, after finding stray troops from the 3rd Division and assuming that they had lost direction. By 7:30 a.m. the 5th Brigade was ready to advance on the second objective and reached Frankfort Trench so depleted, that the troops fell back to Munich trench, Wagon Road then Crater Lane in the German front line. The reserve brigade moved forward at the same time and two battalions were sent to reinforce the 5th Brigade at the first objective. At 9:00 a.m. the remainder of the 6th Brigade was ordered back to the British front line to reorganise and two attacks by the reserve brigade were ordered then cancelled. Overnight the ground was consolidated and two 37th Division battalions were sent up from corps reserve next morning.^[36]

The 3rd Division attacked Serre with two brigades, the 8th Brigade on the right using all four battalions and the 76th Brigade on the left attacking with two battalions and two in support, with 36 machine-guns. Waist-deep mud caused a fiasco; some troops from the 8th Brigade reached the German support line, then fell back and some lost direction. The 76th Brigade had the same trouble and at 6:30 a.m. an attempt was made to collect exhausted men scattered around in shell-holes. At 4:30 p.m. all operations were cancelled.^[37]

In XIII Corps, the 31st Division was to attack with the 92nd Brigade on a 500 yards (460 m) front to form a defensive flank. Two battalions advanced at midnight with snipers and Lewis gunners in support. The main attack began at 5:45 a.m. and the German first line was easily occupied. The advance to the support trench was contested all morning, with German bombers counter-attacking towards Star Wood. Carrying parties were held up in no man's land by German artillery fire and at 9:30 a.m.a German attack from Star Wood in the open was "destroyed" by British machine-gun fire from the flank. Due to the failure of the 3rd Division attack, the brigade was ordered to retire at 5:25 p.m. which was carried out by 9:30 p.m.^[38]

14 November In II Corps, the 19th Division raided Stump Road and Lucky Way and began the relief of the 39th Division by extending its front to the Ancre, which was completed in the early hours of 15 November. In V Corps the 63rd Division continued an attack on Beaucourt Trench at 6:20 a.m. advancing from Station Road and losing direction in the mist. Some troops got to within 200 yards (180 m) of Beaucourt Trench and waited for the attack due at 7:45 a.m. The 190th Brigade advanced on time, linked with the troops near the objective and entered Beaucourt, taking 500 prisoners and digging in around the eastern outskirts. Beaucourt Trench was captured on the left and troops began to bomb down it towards Leave Avenue but no troops of the 51st Division were found. Two tanks were sent forward to help mop up German troops holding out in the front line, one bogged but the other helped take "The Strongpoint" where 400 Germans surrendered. Dugouts towards Station Road yielded another 200 prisoners. At 1:00 p.m. German troops were seen massing near Baillescourt Farm and dispersed by artillery; the captured ground was consolidated overnight.^[39]

The 51st Division was supposed to have attacked at 6:20 a.m. (when the 37th Division brigade, attached to the 63rd Division advanced) but the orders were late and only strong patrols could be organised in time, which were forced back by the Germans. At 8:30 a.m. Munich Trench was occupied but British artillery began to bombard it at 11:00 a.m. forcing the infantry out into shell-holes. A company tried to bomb down Leave Avenue with no effect and during the night the digging of New Munich Trench began, in ignorance of the German evacuation of Munich Trench. The 2nd Division attacked Munich Trench at 6:20 a.m. by advancing an hour before zero but had many casualties from an inaccurate British barrage. Many troops got lost in the mist and some strayed into Leave Avenue in the 51st Division area, thinking that it was Munich Trench, where they were pinned down. Troops which did reach Munich Trench were severely depleted and confusion reigned when some German troops wanted to surrender and others refused. On the left flank, Lager Alley was crossed unrecognised, because of the bombardment and the troops extended the British hold on Serre Trench. Troops withdrew from Munich Trench later in the morning to Wagon Road where they were joined by part of a reserve battalion. On the left flank of the attack, a battalion took over the defensive flank south of the Quadrilateral–Lager Alley, which was linked to the British trench by Cat Street tunnel. Believing that Munich Trench had been captured, two battalions were ordered to attack Frankfort Trench at 2:45 p.m. and were surprised by German machine-gun fire from Munich Trench; the survivors withdrew to Wagon Road.^[40]

Air operations

Air observation for the infantry attack which began on 13 November was not possible, because of dense white fog during the day. On the morning of 14 November the mist cleared and 4 and 15 Squadrons flew contact patrols, which revealed the capture of Beaucourt and ground to the north-west. Artillery observation flights gave the positions of 157 German batteries, many of which were silenced by counter-battery fire. German infantry were harassed from the air; 300 German troops spotted in a ravine north of Beaucourt were heavily bombarded by British heavy artillery after a "zone call".^{[Note 10]} Another observer directing fire from a siege battery saw approximately 250 German infantry sheltering in trenches, brought immediate artillery fire on them and then the crew strafed them. Two battalions of infantry were caught on the road near Achiet-le-Petit and heavily bombarded. During the night ten aircraft from 18 Squadron made low attacks on railway stations, trains and road transport with bombs and machine-guns. A German aircraft followed two of the British aircraft to their base and bombed the aerodrome, leaving craters in the landing-ground. A dummy landing-ground was illuminated as a ruse and was machine-gunned by a German aircraft later that night.^[41]

There was good flying weather on 16 and 17 November and frost which improved the going for the infantry. Artillery cooperation worked well on 16 November when area calls from 4, 7 and 15 Squadron aircraft led to "devastating" fire on trenches full of German infantry. An artillery battery was destroyed, seven gun-pits were demolished and 19 damaged, many of the 57 German batteries firing in the area being silenced. Contact patrols found the location of British troops easily, although one aircraft was shot down and two observers returned wounded. The railway junction at Hirson 90 miles (140 km) away, was bombed by 27 Squadron, attacking from 1,000 feet (300 m), hitting coaches, waggons in sidings and two station buildings. Other squadrons raided supply dumps at Courselles and Logeast Wood.^[42] Air fighting on 16 November began when six British aircraft intercepted three German two-seaters, which had been sent to attack British artillery observation aircraft and shot them down. A new Albatros was captured and four more German aircraft were shot down by offensive patrols, which lost two aircraft. During the night bombing and machine-gun attacks resumed on German railheads, supply dumps and an airfield near Flesquières, while German night bombers raided a French airfield at Cachy and hit 21 aircraft. On 17 November fewer combats with German aircraft occurred, three aircraft being lost and three German aircraft being shot down. On 18 November, the final day of the ground operation, a thaw set in and rain and snow reduced visibility, making it impossible for British troops to be seen, even at low level.^[43]

Subsidiary operations 15–17 November

15 November In II Corps, the 39th Division completed the capture of Schwaben Redoubt, which took until 11:00 p.m. In V Corps the 37th Division relieved the 63rd Division and linked with the 51st Division to the north. Bombing attacks began up Beaucourt Trench towards Munich Trench, which reached the 51st Division around 10:00 a.m. Patrols to Muck and Railway trenches found them empty (except for mud). Companies of the 51st and 2nd divisions attacked at 9:00 a.m. and were caught in their barrage, some troops reaching Frankfort Trench then returning to New Munich Trench. A 2nd Division attack with two battalions of the 37th Division lost direction in the mist and fell back to Wagon Road with many casualties, while a third battalion strengthened the left flank by bombing forward and building a strongpoint in the Quadrilateral, near the top of Redan Ridge, as two tanks in support bogged down early.^[44]

16–17 November After dark, the 37th Division in the V Corps area, pushed up Ancre Trench and set up posts in Bois d'Hollande and at Railway and Muck trenches. The 32nd Division, from II Corps reserve, took over from the 2nd Division on the northern defensive flank, where there was considerable confusion over the location of the front line. During the night the right linked up with the 51st Division at New Munich Trench and Leave Avenue. During 17 November the 32nd Division extended to the right to relieve the 51st Division.^[45]

Final attack

18 November The first snow fell on the night of 17/18 November and the attack at 6:10 a.m. began in sleet, which later turned to rain; visibility being nil. In II Corps the 4th Canadian Division was to attack Desire and Desire Support trenches south of Grandcourt, roughly parallel to the Ancre. On the extreme right of the attack, east of the road towards Pys the 10th Brigade attacked to form the eastern flank of the attack and was obstructed by a new German trench; on the far right the brigade was hampered by a British smoke barrage. Fire from numerous machine-guns, forced survivors from the 46th Battalion to retire. The 50th Battalion companies found little German resistance, lost touch with the 11th Brigade to the left, took 100 prisoners and began digging in behind Desire Support Trench, before losses from flanking fire forced them to retreat to Regina Trench.^[46] The 11th Brigade attacked in "blinding sleet"; the 75th Battalion lost direction and veered west, crossing the Courcelette–Pys road but the brigade reached the rest its objectives, taking most of Desire Support Trench. Patrols went forward to Grandcourt Trench, found a few Germans, then took prisoner a German detachment near Coulee Trench, 620 Germans being captured in all.^[45]

West of the Canadians the 18th Division attacked with the 55th Brigade, which assembled in no man's land on the snow. By 8:10 a.m. Desire Trench on the right flank next to the Canadians was captured and a gap between the two right-hand battalions was closed by converging grenade attacks. The two battalions on the left flank disappeared into a gap where the 19th Division had lost direction and veered to the left. German machine-gunners moved into the gap and annihilated two companies and seven runners sent towards the missing battalions were killed.^{[47][Note 11]} The battalions had been badly hit by German shellfire and the Germans held on to Point 66 on the Courcelette–Grandcourt road, before bombing attacks westwards along Desire Trench until night fell, which allowed the left flanking battalion to reach part of its objective. Posts west of Point 66 were withdrawn and Point 66 was connected to Regina Trench.^[48] Next morning more patrols moved west along the trench and by last light it was found that the Germans had withdrawn from the trench as far as Stump Road.^[49]

The 19th Division attacked with two brigades. On the right the 57th Brigade advance reached German positions west of Stump road on the boundary of the 18th Division and pressed on before being cut off and taken prisoner; 70 British troops managing to escape much later on. Further west the British lost direction in the snow, found it again, then on the right were stopped by uncut wire with many casualties. On the left, troops got into the Grandcourt line and pushed across Battery Valley on a front of 300 yards (270 m), into the south-western part of Grandcourt. The 56th Brigade advanced on the St. Pierre Divion–Grandcourt road and along the railway to meet V Corps at Beaucourt. On the right, where the ground to the right of Hansa Road was firm, the attack reached the west end of Grandcourt and the attackers bombed their way to the 57th Brigade troops already there. The left battalions moved forward up the embankment (which was on the north bank of the Ancre where the advance began but was on the south bank between Beaucourt and Grandcourt) parallel to a platoon across the river at Beaucourt Mill, then passed north of the west end of Grandcourt. The ground on the railway and the road at the edge of Grandcourt was consolidated by Royal Engineers. The left battalion of the division was to capture Baillescourt Farm on the north bank of the Ancre but one company was stopped by machine-gun fire from Grandcourt, as the other advanced along the railway embankment and sent out a patrol which met one from V Corps.^[50]

V Corps attacked with two divisions north of the Ancre river. The 37th Division moved on its right through Beaucourt and at about 1:00 a.m., established posts from Bois d'Hollonde west to the Puisieux road and south to Ancre Trench. At dawn both brigades held Muck Trench and were ready to advance, once the 32nd Division on the left captured Frankfort Trench. At zero hour, patrols found German troops in Railway Trench; further to the left British troops bombed their way to the junction of Leave Avenue and Frankfort Trench, where the meeting with the 32nd Division was expected. Puisieux Trench was entered with difficulty and captured down to the Ancre and a patrol met the 19th Division troops on the railway.^[51]

The 32nd Division was to attack Munich and Frankfort trenches, between Leave Avenue and Lager Alley. On the right the 97th Brigade advanced with all four battalions at 6:10 a.m., through sleet and the right-hand battalion was soon stopped by machine-gun fire. The right flank of the centre right battalion was also stopped but further left the advance reached Munich and Frankfort trenches, where the British were cut off and captured. Troops on the left were stopped at a strong-point in Munich Trench and held on in no-man's-land until dark. Further left the junction of Lager Alley was captured and down the hill, touch was gained with the 14th Brigade. The 14th Brigade was to capture Ten Tree Alley 500 yards (460 m) forward and form a defensive flank. One Battalion began early and advanced down Lager Alley, with its left on Serre Trench and descended the valley towards the village which some troops reached, although most were captured or killed during the day. The next battalion on the left was quickly stopped by German machine-gun fire, after the British barrage fell 600 yards (550 m) too far forward and attempts to bomb forward failed, the battalions of 97th Brigade rallying in Wagon Road and New Munich Trench. German artillery fire was more effective, cutting communication apart from pigeons and runners. The only gain for the brigade was on the left flank near the Quadrilateral where a slight advance was made and consolidated.^[51] Ninety men of the 16th Battalion, Highland Light Infantry (the "Glasgow Boys Brigade" Pals battalion) were cut off in Frankfort Trench, where they held out until 21 November when 45 survivors (thirty of them wounded) surrendered.^[52]

German First Army

13–15 November

The night of 12/13 November was quiet, then near dawn a mist formed and cut visibility to nil. At 6:45 a.m. a hurricane bombardment began on the German front line and a mine went off in the crater left over from the mine of 1 July in the Hawthorn Redoubt. Around Serre the 52nd Division began the defence of the village on 13 November which lasted for several days. The 52nd Division had detected British digging in no-man's-land, despite the fog and a patrol reported the British approach.^[53] At the beginning of the attack, the confusion caused by mist allowed the British to get into the first two trenches north of Serre, which were eventually recaptured.^[54] After the quiet night the 23rd Division troops from Infantry Regiment 62 at Beaumont Hamel, stood to at dawn in the fog and were surprised by the arrival of the post, which reduced tension; sentries then reported many footfalls in no man's land. The north flank was devastated by the mine explosion and the front line was simultaneously deluged by shrapnel and mortar fire. The German troops followed the drill for meeting an attack, by each throwing a grenade as they lined the parapet, as machine-gunners fired into no-man's-land. The British arrived at intervals in scattered groups, many smoking with their rifles slung.^[55]

Signal rockets were fired for the artillery but in the fog went unseen, so the rest were thrown into no-man's-land to illuminate the British as they drew close, many falling into German trenches as they were shot. After about two hours the British attack abated, when cheers were heard from Beaumont Hamel behind them and a line of German troops were seen in the mist, guarded by British troops. The mist lifted a little and many lines and waves of British troops were seen on the right flank advancing unopposed. A defensive flank was formed and fire opened on the British, causing many casualties, before a machine-gun began firing at them from behind on the left, forcing them under cover. A machine-gun began enfilade fire from the right, causing many casualties. An unarmed German officer appeared and announced that he was a prisoner and that the British were through the support and reserve positions and in Beaumont Hamel. The Germans discussed their prospects and surrendered when British troops began bombing along the trench.^[56]

Further south Infantry Regiment 55 of the 38th Division was forced to withdraw to avoid being surrounded, after the breakthrough at Beaumont Hamel, allowing the British to advance around St Pierre Divion and Beaucourt; the British taking 2,000 prisoners, including all of I Battalion of the 23rd Regiment and its headquarters.^[57] On the north bank, the survivors of Infantry Regiment 55 made a stand in the Schloss-stellung on the west side of Beaucourt, running towards Alt-Wurttemburgfeste ("Old Württemberg Redoubt") from which, with part of the 223rd Division, they devastated two British battalions advancing closer to the river, while its regiment in reserve was rushed to Serre Riegel early on 14 November.^[58] On the south bank, the 38th Division was being relieved by part of the 223rd Division, which having been formed a month earlier from youths and returning wounded was of limited efficiency. The British barrage here was accurate and heavy and St Pierre Divion was captured with the loss of 1,380 prisoners.^[59]

Attempts to reinforce the troops on both banks of the Ancre began immediately. The 144th Regiment of the 223rd Division was rushed to Beaucourt and Ancre Trench (behind Beaucourt). A battalion moved up on the south bank of the river then crossed an improvised bridge to occupy Puisieux Trench but no counter-attack could be organised amid the chaos. Some German troops in Beaucourt were attacked from behind and by 10:30 a.m. the British were consolidating the village.^[60] Part of the 26th Reserve Division was hurried south from near Cambrai by lorry and forced march, then sent to join the remnants of the 12th Division around Beaumont Hamel.^[61] Ground to a depth of 2,000 metres (2,200 yd) had been lost in the Ancre valley and German troops fought hard to contain the British advance around Beaucourt and Grandcourt. In the morning of 14 November British artillery cut the link between the Schloss-stellung and Alt-Wurttemburgfeste but British attacks were defeated with many losses. South and east of Grandcourt, British attacks from Stump Road failed by mid-morning.^[62] The German command believed that the British offensive had ended on 14 November and the German Second Army commander General Max von Gallwitz and Crown Prince Rupprecht requested leave (Gallwitz had to stay on duty).^[60]

18 November

The British tried again to capture Serre by taking Soden Redoubt to the south and early on had success in confused fighting, when the headquarters of III Battalion, Infantry Regiment 77 in Serre was captured. In a costly defensive success, which owed much to the great assistance from German artillery, the British attack was defeated by the evening, with many British soldiers being captured as they tried to withdraw and their prisoners liberated.^{[63][Note 12]} In the Ancre valley the 58th Division on the south bank, was being relieved by the 56th Division when the British attack began. The German positions began 300 metres (330 yd) north of Regina Trench at Alter Dessauer Riegel ("Desire Trench") which was held by patrols as a decoy away from Dessauer Riegel–Leipziger Riegel ("Desire Support Trench"), the main line of defence 150 metres (160 yd) back in Kleine Mulde ("Little Gully"), an eastern extension of Stallmulde ("Little Hollow"). Stallmulde was 650 metres (710 yd) south of Baum Mulde ("Boom Ravine"). 100 metres (110 yd) behind these defences lay Grimmaer Riegel, which the Germans were able partly to wire before 18 November. The last line of defence was Grandcourt Riegel ("Grandcourt Trench") and machine-gun nests along Boom Ravine.^[64]

The British attack got forward 600 yards (550 m) beyond Beaucourt, despite many casualties caused by massed German machine-gun fire and local counter-attacks. On the south bank the front of the 106th Regiment was broken and I Battalion 120th Reserve Regiment was destroyed by an attack from behind. The 144th and 29th Regiments defended Grandcourt, where the 29th Regiment was defeated and the survivors pushed into the area of the 144th Regiment further east. South of Grandcourt, at 6:30 a.m. the 173rd regiment had been overrun by the time they emerged from their dug outs. The British battalion (8th North Staffordshires) pressed on and was cut off and eventually surrendered.^[65] German troops who had not been pushed back into Grandcourt Riegel, were ordered to retire there in the evening of 18 November. Further east the German defence of the Pys–Courcelette road was forced back, until a counter-attack stopped the British advance. By the evening, German defenders held ground either side of the road, in an arc between Dessauer Riegel and the east end of Regina Trench.^[66]

French Tenth and Sixth armies

French operations south of the Somme were delayed by bad weather until 7 November.^{[Note 13]} Bois Kratz, Pressoir and Ablaincourt were captured by the Tench Army and numerous German counter-attacks, including a big attack after a two-day bombardment at Bois Kratz and Pressoir on 15 November, were defeated after the Germans had gained a foothold at the east end of Pressoir and then been pushed out. North of the Somme German attacks on the Sixth Army, from south of Bouchavesnes to Lesboeufs captured the north corner and western fringe the St. Pierre Vaast Wood but were repulsed along the rest of the attack front; French counter-attacks made progress on the northern spur of St. Pierre Vaast Wood. On 16 November the Germans entered Saillisel in the morning and were forced out by the evening as they were pushed out of Pressoir further south. Three German divisions suffered heavy losses and French airmen had fought 54 engagements with German aeroplanes; on the night of 16/17 November French night bombers dropped 1.5 long tons (1.5 t) of bombs on a railway station and aviation park.^[67] Preparations began for an advance to a line Mazancourt–Happlincourt–Biaches, ready for a spring offensive.^[68]

Aftermath

Analysis

A German First Army investigation of the débâcle at Beaumont Hamel, found that the weeks of bombardment, lately from the flank and rear had destroyed the German trenches and wire, although most dugouts 6–8 metres (20–26 ft) deep in the front line survived. Each morning the British simulation of an attack sapped the alertness of the defenders. The attack began after 15 minutes of Trommelfeuer ("drumfire") while the German defensive barrage failed to have much effect, due to visibility being nil in the fog, leaving the infantry unsupported. The 12th Division was blamed for lacking solidity and discipline and the divisional headquarters was severely criticised for inertia, which had only remedied when the First Army headquarters took over.^[69]

Casualties

Casualties in the 32nd Division 18–24 November were 2,524, more than 50% being "missing".^[70] Losses in the 37th Division 13–24 November were 2,469 (including sickness as well as casualties)^[70] and in the 51st Division 13–17 November, were approximately 2,200.^[27] Losses of the 2nd Division 13–16 November were approximately 3,000 and those of the 3rd Division 13–15 November were 2,400.^[71] The 63rd Division lost approximately 3,500 casualties, 13–15 November.^[72] The British Fifth Army had 23,274 casualties 11–24 November and inflicted so many casualties (45,000 including 7,183 prisoners 1–18 November)^[73] on the defending German divisions, that the German command had to replace two of them twice, in what Ludendorff called "a particularly heavy blow".^{[2][Note 14]}

Subsequent operations

On 19 November troops of the 19th Division defeated a German counter-attack at the west end of Grandcourt. Another defensive position was dug from the Ancre to Battery Alley 500 yards (460 m) away from the Grandcourt line, from which the British retired as they were overlooked from the south end of the Grandcourt line, where it was still held by the Germans. Puisieux trench was abandoned, when the 19th Division was withdrawn from Grandcourt that night.^[74] The Battle of the Somme lasted from 1 July – 18 November on the British reckoning. In the southern sector, the British Fourth Army ended operations on 16 November and on the French sector the final action took place on 14–15 November in St Pierre Vaast Wood. On 22 November part of the 96th Brigade tried to rescue infantry of the 16th Highland Light Infantry Battalion, who were trapped in Frankfort Trench south of the Soden Redoubt but the effort failed and the survivors surrendered.^[75] The German (First and Second), French (Sixth and Tenth) and British (Fourth and Reserve/Fifth) armies settled down to endure winter on the Somme.^[76] The British kept pressure on the German defenders with artillery fire, air attacks during bright spells and propaganda leaflets purporting to be from German prisoners praising their treatment, although mud, icy winds, sleet and driving rain may have had more effect. Illness and exposure became common among German troops and at the end of 1916 was almost universal, leading to numerous reports warning that the German troops in the area were unlikely to be able to resist further attacks.^[75] British attacks resumed on the Ancre in January 1917.^[77]
