These measures gave each platoon a clearer picture of how it fitted into the greater battle plan, and in so doing, reduced the command and control problems that plagued First World War combat. Operations along the Vimy Ridge were accompanied by extensive underground excavations. The Arras–Vimy sector was conducive to tunnelling owing to the soft, porous yet extremely stable nature of the chalk underground. Underground warfare had been conducted on the Vimy sector since 1915. Bavarian engineers had blown twenty mines in the sector by March 1915. By early 1916, German miners had gained an advantage over their French counterparts. British tunnelling companies of the Royal Engineers took over progressively from the French between February and May 1916. The units active around Vimy were the 172nd, 175th, 176th, 182nd, 184th and 185th Tunnelling Companies. On their arrival, the British began offensive mining against German miners, first stopping the German underground advance and then developing a defensive strategy that prevented the Germans from gaining a tactical advantage by mining.

    From spring 1916, the British had deployed five tunnelling companies along the Vimy Ridge and during the first two months of their tenure of the area, 70 mines were fired, mostly by the Germans. Between October 1915 and April 1917 an estimated 150 French, British and German charges were fired in this 7 kilometres (4.3 mi) sector of the Western Front. In May 1916, Operation Schleswig-Holstein, a German infantry attack, forced the British back 640 metres (700 yd), to stop British mining by capturing the shaft entrances. From June 1916, the Germans withdrew many miners to work in coal mines in Germany. In the second half of 1916, the British constructed strong defensive underground positions and from August 1916, the Royal Engineers developed a mining scheme for a big infantry attack on the Vimy Ridge proposed for autumn 1916, although this was postponed. After September 1916, when the Royal Engineers had completed their network of defensive galleries along most of the front line, offensive mining largely ceased although activities continued until 1917. The British gallery network beneath Vimy Ridge eventually grew to a length of 12 kilometres (7.5 mi). The Canadian Corps was posted to the northern part of Vimy Ridge in October 1916 and preparations for an attack were revived in February 1917. British tunnelling companies created extensive underground networks and fortifications.

    The British tunnellers had gained an advantage over the German miners by the Autumn of 1916, which virtually ended the German underground threat. The British turned to digging 12 subways about 25 ft (7.6 m) down, to the front line, the longest tunnel being 1,883 yd (1,722 m) long of the 10,500 yd (9,600 m) dug. In one sector, four Tunnelling companies of 500 men each, worked around-the-clock in 18-hour shifts for two months to dig 12 mi (20 km) of subways for foot traffic, tramways with rails for hand-drawn trolleys and a light railway system. Most tunnels were lit by electricity, accommodated telephone cables and some had trams and water supplies. Caverns were dug into the sides for brigade and battalion HQs, first aid posts and store-rooms. The subways were found to be a most efficient way to relieve troops in the line, form up for the attack and then to evacuate wounded. Some of the tunnels were continued into Russian saps with exits in mine craters in no man's land and new mines were laid. Galleries were dug to be opened after the attack for communication or cable trenches, the work being done by the 172nd, 176th, 182nd and 185th Tunnelling companies (Lieutenant-Colonel G. C. Williams, Controller of Mines First Army).

    In June 1916, the amount of French artillery at Verdun had been increased to 2,708 guns, including 1,138 × 75 mm field guns; the French and German armies fired c. 10,000,000 shells, with a weight of 1,350,000 long tons (1,370,000 t) from February–December. The German offensive had been contained by French reinforcements, difficulties of terrain and the weather by May, with the 5th Army infantry stuck in tactically dangerous positions, overlooked by the French on the east bank and the west bank, instead of secure on the Meuse Heights. Attrition of the French forces was inflicted by constant infantry attacks, which were vastly more costly than waiting for French counter-attacks and defeating them with artillery. The stalemate was broken by the Brusilov Offensive and the Anglo-French relief offensive on the Somme, which had been expected to lead to the collapse of the Anglo-French armies.

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

    By 5 September the garrison had been able to strengthen some parts of the main defensive line with the help of the newly arriving reinforcements. In Sector I, forts 1 to 5 were guarded by nine and a half battalions chiefly from the Romanian 36th Infantry regiment, stiffened with battalions from the 40th, 75th and 80th infantry regiments, as well as four companies from 48th and 72nd militia battalions. Sector II was reinforced with 4 battalions of the 74th and 75th regiments to a total of 8 battalions, but only after the attack had started.

    Between Vauxaillon and Reims and on the Moronvilliers heights the French had captured much of the German defensive zone, despite the failure to break through and Army Group German Crown Prince counter-attacked before the French could consolidate, mostly by night towards the summits of the Chemin des Dames and the Moronvilliers massif. During the nights of the 6/7 and 7/8 May the Germans attacked from Vauxaillon to Craonne and on the night of 8/9 May German attacks were repulsed at Cerny, La Bovelle, Heutebise Farm and the Californie Plateau. Next day German counter-attacks on Chevreux, north-east of Craonne at the foot of the east end of the Chemin des Dames were defeated. More attacks on the night of 9/10 May were defeated by the French artillery and machine-gun fire; and the French managed to advance on the northern slopes of the Vauclerc Plateau. On 10 May another German attack at Chevreux was defeated and the French advanced north of Sancy. On the night of 10/11 May and the following day, German attacks were repulsed on the Californie Plateau and at Cerny.

    The British XVII Corps, commanded by Lieutenant-General Sir Julian Byng, relieved the French Tenth Army in the sector in February 1916, permitting the French to expand their operations at Verdun. The British soon discovered that German tunnelling companies had taken advantage of the relative calm on the surface to build an extensive network of tunnels and deep mines from which they would attack French positions by setting off explosive charges underneath their trenches. The Royal Engineers immediately deployed specialist tunnelling companies along the front to combat the German mining operations. In response to increased British mining aggression, German artillery and trench mortar fire intensified in early May 1916. On 21 May 1916, after shelling both forward trenches and divisional artillery positions from no less than 80 out-of-sight batteries on the reverse slope of the ridge, the German infantry began operation Schleswig Holstein, an attack on the British lines along a 1,800-metre (2,000 yd) front in an effort to eject them from positions along the ridge. The Germans captured several British-controlled tunnels and mine craters before halting their advance and entrenching their positions.

    On 30 March the Germans attacked around Le Hamel and although this was turned back, they succeeded in making gains around Hangard Wood. Five days later, the Germans renewed their drive towards Villers-Bretonneux. Part of the German attack fell on the centre and left of the French First Army. The French line fell back, but a counter-attack regained much of the ground. From north to south the line was held by British and Australian troops of the 14th (Light) Division, the 35th Australian Battalion and the 18th (Eastern) Division. By 4 April the 14th (Light) Division, around Le Hamel, had fallen back under attack from the German 228th Division. The Australians held off the 9th Bavarian Reserve Division and the 18th Division repulsed the German Guards Ersatz Division and 19th Division. The British were forced to retire by the retreat of the 14th (Light) Division, where the 41st Brigade had been pushed back for 500 yards (460 m) "in some disorder" and then retired to a ridge another 3,000 yards (2,700 m) back, which left the right flank of the 42nd Brigade uncovered. The line west of Le Hamel was reinforced by the arrival of the 15th Australian Brigade. In the afternoon, the Germans resumed their efforts and pushed the 18th Division in the south, at which point Villers-Bretonneux appeared ready to fall. The Germans came within 440 yards (400 m) of the town but Colonel Goddard of the 35th Australian Battalion, in command of the sector, ordered a surprise late afternoon counter-attack on 4 April, by the 36th Australian Battalion with c. 1000 men, supported by a company from the 35th Australian Battalion and his reserve, the 6th Battalion London Regiment. Advancing by section rushes, they pushed the Germans back towards Monument Wood and then north of Lancer Wood and forced two German divisions to retreat from Villers-Bretonneux. Flanking movements by British cavalry and Australian infantry from the 33rd and 34th Battalions helped consolidate the British gains. Further fighting around the village took place later in the month during the Second Battle of Villers-Bretonneux. The attack on Villers-Bretonneux was the last significant German attack of Operation Michael (known to the British as the First Battle of the Somme, 1918). After the failure of the German forces to achieve their objectives, Ludendorff ended the offensive to avoid a battle of attrition. The 9th Australian Brigade had 665 casualties from c. 2,250 men engaged. German casualties were not known but there were 498 losses in two of the regiments engaged. The 9th Australian Brigade recorded 4,000 dead German soldiers on their front and the 18th Division had "severe" losses and took 259 prisoners from the 9th Bavarian Reserve, Guards Ersatz and 19th divisions.

    Draught animals suffered from the weather, short rations and overloading; the British artillery soon had a shortage of 3,500 horses and several immobilised heavy artillery batteries. The length of the Western Front was reduced by 25 miles (40 km), which needed 13–14 fewer German divisions to hold. The Allied spring offensive had been forestalled and the subsidiary French attack up the Oise valley negated. The main French breakthrough offensive on the Aisne (the Nivelle Offensive), forced the Germans to withdraw to the Hindenburg Line defences behind the existing front line on the Aisne. German counter-attacks became increasingly costly during the battle; after four days 20,000 prisoners had been taken by the French armies and c. 238,000 casualties were inflicted on German armies opposite the French and Belgian fronts between April and July.

    In May, Falkenhayn estimated that the French had lost 525,000 men against 250,000 German casualties and that the French strategic reserve had been reduced to 300,000 troops. Actual French losses were c. 130,000 by 1 May and the Noria system had enabled 42 divisions to be withdrawn and rested, when their casualties reached 50 percent. Of the 330 infantry battalions of the French metropolitan army, 259 (78 percent) went to Verdun, against 48 German divisions, 25 percent of the Westheer (western army). Afflerbach wrote that 85 French divisions fought at Verdun and that from February to August, the ratio of German to French losses was 1:1.1, not the third of French losses assumed by Falkenhayn. By 31 August, 5th Army losses were 281,000 and French casualties numbered 315,000 men.
