1914 In 1914, La Boisselle was a village of on the right of the D 929 Albert–Bapaume road, at the junction of the D 104 to Contalmaison. On 26 September, the French
11th Division attacked eastwards, north of the
River Somme but after French Territorial divisions were forced back from Bapaume, the division was ordered back to defend bridgeheads from Maricourt to Mametz. The
II Bavarian Corps attacked on 27 September between the Somme and the D 929, the
Roman road from Bapaume to Albert and Amiens, intending to reach the
River Ancre and then continue westwards along the Somme valley. The
3rd Bavarian Division advanced close to Montauban and Maricourt against scattered resistance from French infantry and cavalry. On 28 September, the French were able to stop the German advance on a line from Maricourt to Fricourt and Thiepval. The
XIV Reserve Corps began operations west of Bapaume on the same day, by advancing down the Bapaume–Albert road to the Ancre river, to complete the advance down the Somme valley to
Amiens but by 29 September the French had stopped the Bavarian advance around Fricourt and La Boisselle. A night attack on
Bécourt, about south of La Boisselle to capture Albert was planned for the evening of 7 October; the Bavarian infantry found that keeping direction in the dark was impossible. Small-arms fire from well dug-in French troops added to the confusion and the attack collapsed, troops being captured in the fiasco. In early November, French artillery reinforcements arrived and bombardments beyond the front line began. On 19 November, two divisions of
XI Corps attacked to pin down German troops but were repulsed and on 28 November an attack by the
XIV Corps managed to advance the French line by . In early December,
IV Corps attacked and gained . The French attacks were costly and pushed forward the front line only a short distance. Attacks by the French
53rd Reserve Division (XI Corps) took place from 17 December at La Boisselle, Mametz, Carnoy and Maricourt. Although wire-cutting had not been completed, the operation was ordered to begin at without artillery support, to gain a measure of surprise. The attackers got beyond the German front line near Mametz and north of Maricourt and then repulsed German counter-attacks from Bernafay Wood and east of Mametz. The advance was contained by German reserves in the support lines and by flanking machine-gun fire. The 118th Infantry Regiment reached the cemetery of La Boisselle and the 19th Infantry Regiment closed on the western fringe of Ovillers. A German counter-bombardment then swept the ground west of Ovillers and Ravine 92, which prevented the approach of French reserves. During the night the French survivors of the attack fell back to the French front line, except at La Boisselle. Next day, XI Corps broke through the German defences at La Boisselle cemetery but was stopped a short distance forward in front of trenches protected by barbed wire. A German counter-attack using incendiary grenades recaptured a trench north of Maricourt and a French counter-attack at by two battalions of the 45th Infantry Regiment and a battalion of the 236th Infantry Regiment, managed to regain a small amount of ground. A German counter-attack on 21 December, near Carnoy was repulsed. On 24 December, XI Corps attacked again at La Boisselle, with the 118th Infantry Regiment and two battalions of the 64th Infantry Regiment at after a bombardment. The 118th Infantry Regiment captured several houses in the south-east of La Boisselle and consolidated the area during the night. The 64th Infantry Regiment overran the German first line but was held up short of the support trench, not been discovered before the attack, then dug in, having suffered many casualties. On 27 December, a German bombardment on the captured positions in La Boisselle was followed by an abortive counter-attack on the 118th Infantry Regiment and the 64th Infantry Regiment. German heavy artillery reinforcements had been brought into the area and made the ground untenable; the French infantry were withdrawn and mine warfare began. Many of the German units that fought on the Somme in 1914 remained in the area and made great efforts to fortify the defensive line, particularly with barbed-wire entanglements to hold the front trench with fewer troops. Railways, roads and waterways connected the battlefront to the Ruhr from where material for (dug-outs) underground for each, excavated every and the front divided into (
barrage sectors).
1915 January began frosty, which solidified the ground but wet weather followed and soon caused diggings to collapse, making movement impossible after a few days, leading to tacit truces to allow supplies to be carried to the front line at night. The rains eased and Bavarian Engineer Regiment 1 continued digging eight galleries at the south end of La Boisselle, towards , which had been captured by the French in December and which became known as (Shell Farm) to the Germans and later Glory Hole by the British. On 5 January, French sappers were heard digging near a gallery and a
camouflet was quickly planted and blown, collapsing the French digging and two German galleries in the vicinity. A charge was blown on 12 January, which killed more than forty French soldiers. On 18 January, Reserve Infantry Regiment 120 made a surprise attack and destroyed the 7th and 8th companies of the 65th Infantry Regiment, taking Fighting continued and on the night of when three more German mines were sprung close to . After the explosions, a large party of German troops advanced and occupied the demolished houses but were not able to advance further against French artillery and small-arms fire. At a French counter-attack drove back the Germans and inflicted about For several more days both sides detonated mines and conducted artillery bombardments, which often prevented infantry attacks. On 1 March, at Bécourt, German infantry massing for an attack were stopped by French artillery and at Carnoy on 15 March, a German mine was sprung and crater-fighting ensued for several days. On the night of a German sapper inadvertently broke into French gallery charged with explosives; a group of volunteers took a tense to dismantle the charge and cut the firing cables. From April 1915 to January 1916, sixty-one mines were sprung around , some with explosive charges. General
Erich von Falkenhayn, the German Chief of the General Staff ( [OHL]), ordered a construction programme in January 1915, to create a systematic defensive system on the Western Front, capable of withstanding attacks indefinitely with a relatively small garrison. Barbed wire obstacles were enlarged from one belt wide to two belts wide and about apart. Double and triple thickness wire was laid high. The front line was increased from one trench to three, dug apart, the first trench ( [battle trench]) to be occupied by sentry groups, the second ( [accommodation trench]) for the front-trench garrison and the third trench for local reserves. The trenches were
traversed and had sentry-posts in concrete recesses built into the parapet. Dugouts had been deepened from to , apart and made large enough for An intermediate line of strong points () about behind the front line was also built. Communication trenches ran back to the reserve position, renamed the second position, which was as well built and wired as the first. The second position was beyond the range of French and British field artillery, to force an attacker to stop and move artillery forward before assaulting the line. In mid-July 1915, extensive troop and artillery movements north of the Ancre were seen by German observers. The type of shell fired by the new artillery changed from high explosive to shrapnel and unexploded shells were found to be of a different design. The new infantry opposite did not continue the
live-and-let-live of their forerunners and a larger number of machine-guns began firing against the German lines, which did not pause every like French
Hotchkiss machine-guns. German troops were reluctant to believe that the British had assembled an army large enough to extend as far south as the Somme but a soldier seen near Thiepval was thought to be a French soldier in a grey hat. By 4 August, it was reported by OHL that the
52nd Division and the
26th Reserve Division had seen a man in
a brown suit. On 9 August, the arrival of the British was revealed when Private William Nicholson of the
6th Black Watch,
51st (Highland) Division was shot and captured during a German trench raid. A second British soldier was captured when troops of the 1st Battalion
East Lancashire Regiment of the
4th Division were wiring in no man's land. The soldier got lost in fog near the Ancre and blundered into the German lines near the (beaver colony) redoubt.
1916 After the (Autumn Battle,
Second Battle of Champagne) in 1915, a third defensive position another back from the was begun in February 1916 and was nearly complete on the Somme front when the battle began. The artillery (barrage sectors) were co-ordinated with the infantry, whose officers were expected to know the batteries covering their sections of the front line and the batteries to be ready to engage fleeting targets. A telephone system was built with lines buried deep for back from the front line, to connect the front line with the artillery. The Somme defences had two inherent weaknesses which the rebuilding had not remedied. Front trenches were on a forward slope, lined by white chalk from the subsoil and easily seen by ground observers. The defences were crowded towards the front trench, with a regiment having two battalions near the front-trench system and the reserve battalion divided between the and the second position, all within and most troops within of the front line, accommodated in the new deep dugouts. The concentration of troops at the front line on a forward slope guaranteed that it would face the bulk of an artillery bombardment, directed by ground observers on clearly marked lines. Digging and wiring of a new third position began in May; civilians were moved away and stocks of ammunition and hand-grenades were increased in the front-line. By mid-June, Below and Rupprecht expected an attack on the 2nd Army which held the front from Noyon northwards to beyond Gommecourt, although Falkenhayn was more concerned about an offensive in Alsace-Lorraine and then a possible attack on the 6th Army, which held the front from near Gommecourt north to
St Eloi, near Ypres. In April, Falkenhayn had suggested a spoiling attack by the 6th Army but lack of troops and artillery, which were engaged in the
Battle of Verdun, made it impractical. Some labour battalions and captured Russian heavy artillery were sent to the 2nd Army and Below proposed a preventive attack in May and a smaller effort from Ovillers to St Pierre Divion in June but got only one extra artillery regiment. On 6 June, Below reported that air reconnaissance indicated that an offensive was being prepared at Fricourt and Gommecourt and that the French had been reinforced south of the Somme, against whom
XVII Corps was overstretched, its twelve regiments holding of front with no reserves. In mid-June, Falkenhayn was sceptical that an offensive was being prepared on the Somme, since a great success would lead to operations in Belgium, when an offensive in Alsace-Lorraine would take the war and its devastation into Germany. More railway activity, fresh digging and camp extensions around Albert, opposite the 2nd Army was seen by German air observers on and spies reported an imminent offensive. On 24 June, a British prisoner spoke of a five-day bombardment to begin on 26 June and local units expected an attack within days. On 27 June, balloons were visible to the Germans, one for each British division; no German reinforcements were sent to the area until 1 July and only then to the 6th Army. At Verdun on 24 June, Crown Prince Wilhelm was ordered to conserve troops, ammunition and equipment and further restrictions were imposed on 1 July, when two divisions were put under OHL control. ==Prelude==
