started a system of alliances designed to assert Prussian dominance over Central Europe. Bismarck's diplomatic maneuvering, and France's maladroit response to such crises as the Ems Dispatch and the Hohenzollern Candidature led to the French declaration of war in 1870. France's subsequent defeat in the Franco-Prussian War, including the loss of its army and the capture of its emperor at Sedan, the loss of territory, including Alsace-Lorraine, and the payment of heavy indemnities, left the French seething and placed the reacquisition of lost territory as a primary goal at the end of the 19th century; the defeat also ended French preeminence in Europe.

Economic rivalry was not only a source for some of the colonial conflicts but also a minor cause for the start of World War I.

The Pre-War Army and mobilization

In common with most other continental European powers, the French Army was organized on the basis of universal conscription. Each year, the "class" of men turning twenty-one in the upcoming year would be inducted into the French Army and spend three years in active service. After leaving active service they would progress through various stages of reserves, each of which involved a lower degree of commitment. * Active Army (20–23) * Reserve of the Active Army (24–34) * Territorial Army (35–41) * Reserve of the Territorial Army (42–48) The peacetime army consisted of 173 infantry regiments, 79 cavalry regiments, and 87 artillery regiments. All were substantially under strength and would be filled out on mobilization by the first three classes of the Reserve (that is, men between 24 and 26). Each regiment would also leave behind a cadre of training personnel to conduct refresher courses for the older reservists, who were organized into 201 Reserve Regiments and 145 Territorial Regiments. Above the regimental level, France was divided into 22 Military Regions, each of which would become an Army Corps on mobilization. At the apex of the French Army was the General Staff, since 1911 under the leadership of General Joseph Joffre. The General Staff was responsible for drawing up the plan for mobilization, known as
Plan XVII Plan XVII () was the name of a "scheme of mobilization and concentration" that was adopted by the French (the peacetime title of the French ) from 1912 to 1914, to be put into effect by the French Army in the event of war between France and G ...
. Using the railroad network, the Army would be shifted from their peacetime garrisons throughout France to the eastern border with Germany. The order for mobilization was given on 1 August 1914, the same day that Germany declared war on Russia. Immediately called to their regiments were the classes of 1896 to 1910, comprising almost three million reservists of 24 to 38 years old.


Organization during the war

Upon mobilization, Joffre became Commander-in-Chief of the French Army. Most of his forces were concentrated in the northeast of France, both to attack Alsace-Lorraine and to meet the expected German offensive through the Low Countries. * First Army (7th, 8th, 13th, 14th, and 21st Army Corps), with the objective of capturing

usage, as well as the increasing significance of the French air force, the Service Aéronautique. At the end of the war on November 11, 1918, the French had called up 8,817,000 men, including 900,000 colonial troops. The French army suffered around 6 million casualties, including 1.4 million dead and 4.2 million wounded, roughly 71% of those who fought.

Joseph Joffre was Commander-in-Chief, a position for which he had been designated since 1911. While serving in this position, Joffre was responsible for development of the

Joffre was thought to be the 'Savior of France' due to his serenity and a refusal to admit defeat, valuable at the beginning of the war, along with his regrouping of retreating Allied forces at the Battle of the Marne. Joffre was effectively relieved of his duties on December 13, 1916, following the heavy human losses at the

and induce a battle of attrition was executed. After a few weeks, the battle became a series of local actions. For the French, the battle signified the strength and fortitude of the French Army. Many military historians consider Verdun the "most demanding" and the "greatest" battle in history. The German attack on Verdun began with one million troops, led by Crown Prince Wilhelm, facing only about 200,000 French soldiers. The following day, the French were forced to withdraw to their second line of trenches, and on February 24, they were pushed back to their third line, only from Verdun. The newly appointed commander of the Verdun sector, General
Philippe Pétain Henri Philippe Benoni Omer Pétain (24 April 1856 – 23 July 1951), commonly known as Philippe Pétain (, ) or Marshal Pétain (french: Maréchal Pétain), was a French general who attained the position of Marshal of France at the end of Worl ...

s. A single road remained open for trucks, enabling a continual flow of supplies to the defenders. The German attacking forces were not able to enter the city of Verdun itself and by December 1916 had been forced back beyond the original French trench lines of February. The sector again became a relatively inactive one as the allied focus shifted to the Somme and the Germans adopted a defensive stance. While generally regarded as a tactical victory for the French, the battle caused massive losses on both sides. French casualties had been higher but the original German objective of taking Verdun while destroying the defending army through a battle of attrition had not succeeded.

By the time the battle was over on May 9, the French had suffered 187,000 casualties, while the Germans suffered 168,000. The Allies eventually suffered over 350,000 casualties fighting the Nivelle Offensive.


Mutinies

In the spring of 1917, after the failed Nivelle Offensive, there were a series of mutinies in the French army. Over 35,000 soldiers were involved with 68 out of 112 divisions affected, but fewer than 3,000 men were punished. Following a series of court-martials, there were 49 documented executions and 2,878 sentences to penal servitude with hard labour. Of the 68 divisions affected by mutinies, 5 had been “profoundly affected”’ 6 had been “very seriously affected”, 15 had been “seriously affected”, 25 were affected by “repeated incidents” and 17 had been affected by “one incident only”, according to statistics compiled by French military historian Guy Pedroncini. Mutinies began in April 1917 after the failure of the
Second Battle of the Aisne The Second Battle of the Aisne (french: Bataille du Chemin des Dames or french: Seconde bataille de l'Aisne, 16 April – mid-May 1917) was the main part of the Nivelle Offensive, a Franco-British attempt to inflict a decisive defeat on the Ger ...
, the main action in the Nivelle Offensive. The mutinies started on April 17 and ended on June 30, 1917. They involved units from nearly half of the French infantry divisions stationed on the Western Front. The mutinies were kept secret at the time, and their full extent and intensity were not revealed for a half-century. The more serious episodes involved only a few units; the mutinies did not threaten complete military collapse, but did make the high command reluctant to launch another offensive. The popular cry was to wait for the arrival of millions of fresh U.S. troops. The mutinous soldiers were motivated by despair, not by politics or pacifism. They feared that mass infantry offensives would never prevail over machine guns and artillery. General Pétain restored morale in the summer of 1917 through a combination of rest rotations for front-line units, furloughs home, and stricter discipline. However, Smith has argued that the mutinies were akin to labour strikes and can be considered political. The soldiers demanded not only peace, leave, and better food, and objected to the use of colonial workers on the home front; they were also concerned about the welfare of their families. The courts-martial were merely symbolic, designed to demonstrate the absolute authority of the high command. The British government was alarmed, for it interpreted the mutinies as a sign of deep malaise in French society, and tried to reinvigorate French morale by launching an offensive at Passchendaele (also known as the
Third Battle of Ypres The Third Battle of Ypres (german: link=no, Dritte Flandernschlacht; french: link=no, Troisième Bataille des Flandres; nl, Derde Slag om Ieper), also known as the Battle of Passchendaele (), was a campaign of the First World War, fought by ...

, 40 French divisions were sent to help them. Those troops finally took part in the battle. Then, the third German offensive was launched against French positions in Champagne. The French troops began to lose ground but eventually, the Germans were stopped by a counterattack led by General Charles Mangin. In July, a last German assault was launched against the French on the Marne. The German troops were crushed by about 40 French divisions helped by British and American troops. This was a turning point in the war on the Western Front.


The Grand Offensive

During the summer of 1918, General Ferdinand Foch was appointed supreme commander of the allied forces. After the decisive defeat of the Germans at the second Battle of the Marne, Foch ordered an offensive against Amiens. Some French units participated in this battle. Then, a general offensive was launched against the German positions in France. The French First Army helped the British troops in the north, while eight French field armies formed the center of the offensive. An additional army was sent to help the Americans. The French forces were the most numerous of all the allied troops, and during the last stage of the war, they took about 140,000 prisoners. British troops spearheaded the main attack by attacking in Flanders and Western Belgium where they first smashed the Hindenburg line. Meanwhile, the more exhausted French army managed to liberate most of northern France and to enter Belgian territory. These numerous offensives left the German army on the verge of disaster and when Germany sought for an armistice, British, French and American troops were ready to launch an important offensive in Lorraine, where the Germans were collapsing.


Other campaigns

While the French Army's main commitment was inevitably to the Western Front, significant forces were deployed in other theatres of war. These included the occupation of the German colonies of

, during the second half of the war. The bulk of the French troops utilized in these campaigns were North African and colonial units, both European and indigenous. However the French reinforcements sent to the Italian Front in 1917 following the Battle of Caporetto were drawn from metropolitan French units, marking a diversion of resources from the Western Front.


Equipment

At the outset of the war, the primary French field gun was the French 75, (75mm caliber, entered service in 1897). The French had about 4,000 of these guns, an adequate number, but despite accuracy, quick firing, and lethality against infantry, German

Uniforms

At the outbreak of war the French Army retained the colourful traditional uniforms of the nineteenth century for active service wear. These included conspicuous features such as blue coats and red trousers for the infantry and cavalry. The French cuirassiers wore plumed helmets and breastplates almost unchanged from the Napoleonic period. From 1903 on several attempts had been made to introduce a more practical field dress but these had been opposed by conservative opinion both within the army and amongst the public at large. In particular, the red trousers worn by the infantry became a political debating point. Adolphe Messimy who was briefly Minister of War in 1911-1912 stated that "This stupid blind attachment to the most visible of colours will have cruel consequences"; however, in the following year, one of his successors, Eugène Étienne, declared "Abolish red trousers? Never!" In order to appease traditionalists, a new cloth was devised woven from red, white and blue threads, known as "

cloth", resulting in a drab purple-brown colour. Unfortunately the red thread could only be produced with a dye made in Germany, so only the blue and white threads were used.

on 10 July 1914 but new issues had not been possible before the outbreak of war a few weeks later. The very heavy French losses during the Battle of the Frontiers can be attributed in part to the high visibility of the French uniforms, combined with peacetime training which placed emphasis on attacking in massed formations. The shortcomings of the uniforms were quickly realized and during the first quarter of 1915 general distribution of horizon-blue clothing in simplified patterns had been undertaken. The long established infantry practice of wearing greatcoats for field service, buttoned back when on the march, was continued in the trenches. British-style puttees were issued in place of leather
