Delville Wood order of battle

The Battle of Delville Wood (15 July – 3 September 1916) was a series of engagements in the 1916 Battle of the Somme in the First World War, between the armies of the German Empire and the British Empire. Delville Wood (Bois d'Elville), was a thick tangle of trees, chiefly beech and hornbeam (the wood has been replanted with oak and birch by the South African government), with dense hazel thickets, intersected by grassy rides, to the east of Longueval. As part of a general offensive starting on 14 July, which became known as the Battle of Bazentin Ridge (14–17 July), General Douglas Haig, Commander of the British Expeditionary Force, intended to capture the German second position between Delville Wood and Bazentin le Petit. The attack achieved this objective and was a considerable though costly success. British attacks and German counter-attacks on the wood continued for the next seven weeks, until just before the Battle of Flers–Courcelette (15–17 September), the third British general attack in the Battle of the Somme. The 1st South African Infantry Brigade made its Western Front début as part of the 9th (Scottish) Division and captured Delville Wood on 15 July. The South Africans held the wood until 19 July, at a cost in casualties similar to those of many British brigades on 1 July. The village and wood formed a salient, which could be fired on by German artillery from three sides. The ground was a rise from Bernafay and Trônes woods, to the middle of the village, neither village or wood could be held without possession of the other. After the Battle of Bazentin Ridge, the British tried to advance on both flanks to straighten the salient at Delville Wood, to reach good jumping off positions for a general attack. The Germans tried to eliminate the salient and to retain the ground, which shielded German positions from view and overlooked British positions. For the rest of July and August, both sides fought for control of the wood and village but struggled to maintain the tempo of operations. Wet weather reduced visibility and made the movement of troops and supplies much more difficult; ammunition shortages and high casualties reduced both sides to piecemeal attacks and piecemeal defence on narrow fronts, except for a small number of bigger and wider-front attacks. Most attacks were defeated by defensive firepower and the effects of inclement weather, which frequently turned the battlefield into a mud slough. Delville Wood is well preserved with the remains of trenches, a museum and a monument to the South African Brigade at the Delville Wood South African National Memorial.

The Delville Wood South African National Memorial is a World War I memorial, located in Delville Wood, near the commune of Longueval, in the Somme department of France. It is opposite the Delville Wood Commonwealth War Graves Commission Cemetery, on the other side of the Longueval–Ginchy road.

Delville Wood Cemetery is a Commonwealth War Graves Commission cemetery located near Longueval, France and the third largest in the Somme battlefield area.

Longueval (French pronunciation: [lɔ̃ɡval]) is a commune in the Somme department in Hauts-de-France in northern France.

The Battle of Pozières (23 July – 3 September 1916) took place in northern France around the village of Pozières, during the Battle of the Somme. The costly fighting ended with the British in possession of the plateau north and east of the village, in a position to menace the German bastion of Thiepval from the rear. The Australian official historian Charles Bean wrote that Pozières ridge "is more densely sown with Australian sacrifice than any other place on earth".

The Second Battle of the Somme of 1918 was fought during the First World War on the Western Front from late August to early September, in the basin of the River Somme. It was part of a series of successful counter-offensives in response to the German Spring Offensive, after a pause for redeployment and supply. The most significant feature of the two 1918 Somme battles was that with the failure of the first 1918 Somme Battle (not to be confused with the 1916 Battle of the Somme) having halted what had begun as a large German offensive, the second formed the central part of the Allies' advance to the Armistice of 11 November.

The Capture of Trônes Wood (8–14 July) was a tactical incident in the First World War, fought by the British Fourth Army and the German 2nd Army, during the Battle of the Somme. Trônes Wood lay on the northern slope of Montauban ridge, between Bernafay Wood and Guillemont. The wood dominated the southern approach to Longueval and Trônes Alley, a German communication trench between Bernafay Wood and the northern tip of Trônes Wood to Guillemont. A light railway ran through the centre, which was in a dip formed by the east end of Caterpillar Valley sloping away to the west. The wood was pear-shaped, with a base about 400 yd (370 m) wide on Montauban ridge, the rest of the wood running north for about 1,400 yd (1,300 m), coming to a point on a rise towards Longueval village. The wood had dense undergrowth which retarded movement, made it difficult to keep direction and during the battle the trees were brought down by shellfire, becoming entangled with barbed wire and strewn with German and British dead. The British attacks were part of preliminary operations, to reach ground from which to begin the second British general attack of the Battle of the Somme, against the German second position from Longueval to Bazentin le Petit on 14 July. The German defenders fought according to a policy of unyielding defence and immediate counter-attack to regain lost ground, intended to delay the Anglo-French advance south of the Albert–Bapaume road and give time for reinforcements sent to the Somme front to arrive.

The Battle of Guillemont (3–6 September 1916) was an attack, during the Battle of the Somme in the First World War, by the British Fourth Army against the German 2nd Army near the village of Guillemont in northern France. The village is on the D 20 running east to Combles and the D 64 south-west to Montauban. Longueval and Delville Wood lie to the north-west and Ginchy to the north-east. The village was on the right flank of the British sector, near the boundary with the French Sixth Army. The Fourth Army had advanced close to Guillemont during the Battle of Bazentin Ridge (14–17 July) and the capture of the village was the culmination of British attacks which began on the night of 22/23 July. The attacks were intended to advance the right flank of the Fourth Army and eliminate a salient further north at Delville Wood. German defences ringed the wood and had observation over the French Sixth Army area to the south, towards the Somme river. Preparatory to a general attack intended for mid-September, from the Somme north to Courcelette (beyond the Albert–Bapaume road), the French Sixth Army, the Fourth Army and the Reserve Army conducted numerous attacks to capture the rest of the German second line and to gain observation over the German third line. The German defences around Guillemont were based on the remaining parts of the second line and fortified villages and farms northwards from Hem, Maurepas and Combles, to Falfemont Farm, Guillemont, Ginchy, Delville Wood and High Wood, which commanded the ground in between. The Battles Nomenclature Committee report of May 1921, called British military operations on the Somme during the fighting for Guillemont, the Battle of Delville Wood (14 July – 3 September) by the Fourth Army and the Battle of Pozières (23 July – 3 September) by the Reserve Army and III Corps of the Fourth Army.Numerous attempts were made by Joseph Joffre, the French supreme commander, Sir Douglas Haig, Ferdinand Foch and the army commanders Henry Rawlinson and Émile Fayolle to co-ordinate joint attacks, which failed due to the recovery of the German 2nd Army from the disorganisation caused by the defeats in early July, disagreements over tactics by Haig and Joffre in July and August and organisational constraints caused by congestion behind the front, roads and tracks obliterated by Anglo-French artillery-fire becoming swamps when it rained and increasing German artillery-fire on targets behind the front line. Inexperience, unreliable machinery, guns, ammunition and an unpredictable flow of supplies from Britain, reduced the effectiveness of the British armies. Difficulty in co-ordinating attacks by the Entente armies and the large number of piecemeal attacks resorted to by the British, have been criticised as costly failures and evidence of muddle and incompetence by the generals. The French Sixth and Tenth armies had similar difficulties and severe strain had been put on the German 2nd and 1st Army (formed on 19 July), forcing them into a similar piecemeal defence. The official historian, Wilfrid Miles, wrote in the History of the Great War volume Military Operations France and Belgium, 1916: 2nd July 1916 to the End of the Battles of the Somme (1938), that the defence of Guillemont was judged by some observers to be the best performance of the war by the German Army on the Western Front. A pause at the end of August in Anglo-French attacks to organise bigger combined attacks and postponements for bad weather, coincided with the largest German counter-attack yet. Joffre, Foch and Haig abandoned attempts to organise large combined attacks, in favour of sequenced army attacks. The capture of the German defences from Cléry north of the Somme to Guillemont from 3 to 6 September brought the Sixth and Fourth armies onto ground which overlooked the German third position. Rain, congestion and relief of tired divisions forced a pause in French attacks until 12 September. At the Battle of Ginchy (9 September) the Fourth Army captured the village, ready to begin the Battle of Flers–Courcelette, (15–22 September).

Guillemont (French pronunciation: [ɡijmɔ̃]) is a commune approximately 13 km (8 mi) east of Albert in the Somme department in Hauts-de-France in northern France. It, like much of the surrounding area, is primarily an agricultural community, but is known for its large Commonwealth War Graves cemetery, which has many visitors. The cemetery began as a field graveyard after the Battle of Guillemont, but was quickly expanded after the Armistice when graves from surrounding areas were centralized here.In World War I, Guillemont was one of several important strategic areas controlled by Germans that effectively divided Allied forces. It was changed hands several times during the war, before being finally taken and held by the British 20th (Light) Division and the 47th Brigade of the 16th (Irish) Division

The Battle of Ginchy took place on 9 September 1916 during the Battle of the Somme, when the 16th (Irish) Division captured the German-held village. Ginchy is 0.93 mi (1.5 km) north-east of Guillemont, at the junction of six roads, on a rise overlooking Combles, 2.5 mi (4 km) to the south-east. After the conclusion of the Battle of Guillemont on 6 September, XIV Corps and XV Corps were required to complete the advance to positions which would give observation over the German third position. The advance was to make ready for a general attack in mid-September, for which the Anglo-French armies had been preparing since early August. British attacks northwards from the boundary between the Fourth Army and the French Sixth Army, from Leuze Wood north to Ginchy, had begun on 3 September when the 7th Division captured the village, before being forced out by a German counter-attack. Attacks on Leuze Wood and attempts to re-take Ginchy on 4 and 5 September were also defeated by German counter-attacks. The 7th Division was relieved by the 16th (Irish) Division and 55th (West Lancashire) Division on the evening of 7 September and the 5th Division was replaced by the 56th (1/1st London) Division on the right at the boundary with the French. On 9 September the British began a bombardment early in the morning but waited until late afternoon to advance, to deny the Germans time to counter-attack before dark. The British assault in the south by the 56th (1/1st London) Division and the 16th (Irish) Division reached Bouleaux Wood but the attack in the centre was repulsed. On the northern flank, Ginchy was captured by the 16th (Irish) Division and several German counter-attacks were defeated. The loss of Ginchy deprived the Germans of observation posts from which they could observe the battlefield. The success eliminated the salient at Delville Wood, which had been costly to defend, due to observed German artillery-fire from three sides and the many counter-attacks by German infantry in July and August; the attack on 31 August, being the largest mounted by the Germans against the British during the battle. The success of the attack by the French Sixth Army on 12 September, in its biggest operation of the battle and the advance of the right flank of the British Fourth Army from 3 to 9 September, enabled both armies to make much bigger attacks. The assaults were sequenced with attacks by the Tenth and Reserve armies in September, which captured much more ground and inflicted approximately 130,000 casualties on the German defenders. Anglo-French attempts to co-ordinate their attacks had failed from July to early September, due to a combination of disagreements between Haig, Joffre and Foch over tactics, supply difficulties, devastated terrain, inclement weather and the increasing defensive power of the German armies. In September, the Allies managed to co-ordinate their attacks; advances on each army front made adjacent German positions vulnerable, which were attacked promptly by the neighbouring army before the Germans recovered from their disorganisation.

The Bernafay Wood British Cemetery is a cemetery located in the Somme region of France commemorating British and Commonwealth soldiers who fought in the Battle of the Somme and against the German 1918 spring offensive in World War I. The cemetery contains mostly those who died between July 1916 and April 1917 and March–August 1918.
