Air warfare

This year also saw the introduction of aeroplanes specifically modified for aerial combat. While planes had already been used in the war for scouting, on 1 April the French pilot Roland Garros became the first to shoot down an enemy plane by using machine guns that fired forward through the propeller blades. This was achieved by crudely reinforcing the blades so bullets which hit them were deflected away.

Several weeks later Garros was forced to land behind German lines. His plane was captured and sent to Dutch engineer Anthony Fokker

In preparation for their attack, the Germans had amassed a concentration of aircraft near the fortress.

Battle of the Somme

The original plans for an attack around the river Somme were modified to let the British make the main effort. This would serve to relieve pressure on the French, as well as the Russia

 launched an attack around the river Somme, supported by five French divisions on their right flank. The attack had been preceded by seven days of heavy artillery bombardment. The experienced French forces were successful in advancing but the British artillery cover had neither blasted away barbed wire, nor destroyed German trenches as effectively as was planned. They suffered the greatest number of casualties (killed, wounded and missing) in a single day in the history of the British army, about 57,000.

Having assessed the air combat over Verdun, the Allies had new aircraft for the attack in the Somme valley. The Verdun lesson learnt, the Allies' tactical aim became the achievement of air superiority

 and the German planes were, indeed, largely swept from the skies over the Somme. The success of the Allied air offensive caused a reorganization of the German air arm, and both sides began using large formations of aircraft rather than relying on individual combat.

British Infantry Morval 25 September 1916
After regrouping, the battle continued throughout July and August, with some success for the British despite the reinforcement of the German lines. By August General Haig had concluded that a breakthrough was unlikely, and instead switched tactics to a series of small unit actions. The effect was to straighten out the front line, which was thought necessary in preparation for a massive artillery bombardment with a major push.

The final phase of the battle of the Somme saw the first use of the tank

 on the battlefield. The Allies prepared an attack that would involve 13 British and Imperial divisions and four French corps. The attack made early progress, advancing 3,500–4,500 yards (3.2–4.1 km) in places, but the tanks had little effect due to their lack of numbers and mechanical unreliability. The final phase of the battle took place in October and early November, again producing limited gains with heavy loss of life. All told, the Somme battle had made penetrations of only five miles (8 km), and failed to reach the original objectives. The British had suffered about 420,000 casualties and the French around 200,000. It is estimated that the Germans lost 465,000, although this figure is controversial.

The Somme led directly to major new developments in infantry organization and tactics; despite the terrible losses of 1 July, some divisions had managed to achieve their objectives with minimal casualties. In examining the reasons behind losses and achievements, the British, and the Colonial contingents, reintroduced the concept of the infantry platoon, following in the footsteps of the French and German armies who were already groping their way towards the use of small tactical units. At the time of the Somme, British senior commanders insisted that the company (120 men) was the smallest unit of manoeuvre; less than a year later, the section of 10 men would be so.

The result was near disastrous losses for Allied air power, particularly for the British, Portuguese, Belgians, and Australians who were struggling with outmoded aircraft, poor training and weak tactics. As a result the Allied air successes over the Somme would not be repeated, and heavy losses were inflicted by the Germans. During their attack at Arras, the British lost 316 air crews and the Canadians lost 114 compared to 44 lost by the Germans. This became known to the RFC as Bloody April.

, after the area where the offensive took place), would be 1.2 million men strong, to be preceded by a week-long artillery bombardment and accompanied by tanks. However, the operation proceeded poorly as the French troops, aided by Australian, Brazilian, Portuguese, and New Zealand troops, had to negotiate rough, upward-sloping terrain. In addition, detailed planning had been dislocated by the voluntary German withdrawal to the Hindenburg Line, secrecy had been compromised, and German planes gained control of the sky making reconnaissance difficult. This allowed the creeping barrage to move too far ahead of the advancing troops. Within a week 100,000 French troops were dead. Despite the heavy casualties and his promise to halt the offensive if it did not produce a breakthrough, Nivelle ordered the attack continued into May.

On 3 May the weary French 2nd Colonial Division, veterans of the Battle of Verdun, refused their orders, arriving drunk and without their weapons. Their officers lacked the means to punish an entire division, and harsh measures were not immediately implemented. Thereupon the mutinies

, south of Ypres, to retake the ground lost in the First and Second Battles of Ypres in 1914. Since 1915 engineers had been digging tunnels under the ridge, and about 500 tonnes (roughly 500,000 kg) of explosives had been planted in 21 mines under the enemy lines. Following four days of heavy bombardment, the explosives in 19 of these mines were set off resulting in the deaths of 10,000 Germans. The offensive that followed again relied on heavy bombardment, but these failed to dislodge the Germans. The offensive, though initially stunningly successful, faltered due to the flooded, muddy ground, and both sides suffered heavy casualties.

On 11 July 1917 during this battle, the Germans introduced a new weapon into the war when they fired gas shells delivered by artillery. The limited size of an artillery shell required that a more potent gas be deployed, and so the Germans employed mustard gas

The ground was generally muddy and pocketed by shell craters, making supply missions and further advancement very difficult.

However, the advance produced an awkward salient and a surprise German counteroffensive, with air cover and their own tanks on 30 November drove the British back to their starting lines. Despite the reversal, the attack had been seen as a success by the Allies and Germans as it proved that tanks could overcome trench defences. The battle had also seen the first massed use of German stosstruppen on the western front, which used infantry infiltration tactics

1918—Final offensives

Western Front 1918 German
Following the successful Allied attack and penetration of the German defences at Cambrai, Ludendorff and Hindenburg determined that the only opportunity for German victory now lay in a decisive attack along the western front during the spring, before American manpower became a significant presence. On 3 March 1918, the Treaty of Brest-Litovsk

 for deployment to the west. This would give them an advantage of 192 divisions to the Allied 178 divisions, which allowed Germany to pull veteran units from the line and retrain them as sturmtruppen. In contrast, the Allies still lacked a unified command and suffered from morale and manpower problems: the British and French armies were sorely depleted, and American troops had not yet transitioned into a combat role.

Ludendorff's strategy would be to launch a massive offensive against the British and Commonwealth designed to separate them from the French and her allies, then drive them back to the channel ports. The attack would combine the new storm troop tactics with ground attack aircraft, tanks, and a carefully planned artillery barrage that would include gas attacks.

France suffered heavy damage in the war. In addition to losing more casualties relative to its population than any other great power, the industrial north-east of the country had been devastated by the war. The provinces overrun by Germany had produced 40% of the nation's coal and 58% of its steel output. Once it was clear that Germany was going to be defeated, Ludendorff had ordered the destruction of the mines in France and Belgium. His goal was to cripple the industries of Germany's main European rival. In order to prevent similar German aggression in the future, France later built a massive series of fortifications along the German border known as the Maginot Line
