The Franco-Prussian War or Franco-German War,[a] often referred to in France as the War of 1870, was a conflict between the Second French Empire (later the Third French Republic) and the North German Confederation led by the Kingdom of Prussia. Lasting from 19 July 1870 to 28 January 1871, the conflict was caused primarily by France's determination to restore its dominant position in continental Europe, which it had lost following Prussia's crushing victory over Austria in 1866.[10] According to some historians, Prussian chancellor Otto von Bismarck deliberately provoked the French into declaring war on Prussia in order to draw four independent southern German states—Baden, Württemberg, Bavaria and Hesse-Darmstadt—to join the North German Confederation; other historians contend that Bismarck exploited the circumstances as they unfolded. None, however, dispute that Bismarck likely recognized the potential for new German alliances, given the situation as a whole.

France mobilised its army on 15 July 1870, leading the North German Confederation to respond with its own mobilisation later that day. On 16 July 1870, the French parliament voted to declare war on Prussia; France invaded German territory on 2 August. The German coalition mobilised its troops much more effectively than the French and invaded northeastern France on 4 August. German forces were superior in numbers, training, and leadership and made more effective use of modern technology, particularly railways and artillery.

A series of swift Prussian and German victories in eastern France, culminating in the siege of Metz and the Battle of Sedan, saw French Emperor Napoleon III captured and the army of the Second Empire decisively defeated; the Government of National Defence declared the Third French Republic in Paris on 4 September and continued the war for another five months. German forces fought and defeated new French armies in northern France, besieging the capital of Paris for over four months, before it fell on 28 January 1871, effectively ending the war.

In the waning days of the war, with German victory all but assured, the German states proclaimed their union as the German Empire under the Prussian king Wilhelm I and Chancellor Bismarck; with the notable exception of Austria, the vast majority of Germans were united under a nation-state for the first time in history. Following an armistice with France, the Treaty of Frankfurt was signed on 10 May 1871, giving Germany billions of francs in war indemnity, as well as most of Alsace and parts of Lorraine, which became the Imperial Territory of Alsace-Lorraine (Reichsland Elsaß-Lothringen).

The war had a lasting impact on Europe. By hastening the process of German unification, it significantly altered the balance of power on the continent; with the new German nation state supplanting France as the dominant European land power. Bismarck maintained great authority in international affairs for two decades, developing a reputation for adept and pragmatic diplomacy that raised Germany's global stature and influence. In France, it brought a final end to imperial rule and began the first lasting republican government. Resentment over France's defeat triggered a revolutionary uprising called the Paris Commune, which managed to seize and hold power for two months before its bloody suppression; the event would influence the politics and policies of the Third Republic.

Causes

The causes of the Franco-Prussian War are strongly rooted in the events surrounding the gradual march toward the unification of the German states under Otto von Bismarck. In the midst of the Austro-Prussian War of 1866, the Empress Eugénie, Foreign Minister Drouyn de Lhuys and War Minister Jacques Louis Randon, worried that a Prussian victory might jeopardize France's status as the dominant power in Europe, gained after the Franco-Austrian War of 1859, unsuccessfully urged Napoleon to implement an armed mediation which would consist in a mobilization and the massing of troops at France's eastern borders while the bulk of the Prussian armies were still engaged in Bohemia, as a warning that no territorial changes could be effected in Germany without consulting France. As a result of Prussia's annexation of several German states which had sided with Austria during the war and the formation of the North German Confederation under Prussia's aegis, French public opinion stiffened and now demanded more firmness as well as territorial compensations. As a result, Napoleon demanded from Prussia a return to the French borders of 1814, with the annexation of Luxembourg, most of Saarland, and the Bavarian Palatinate. Bismarck flatly refused what he disdainfully termed France's "politique des pourboires" He then communicated Napoleon's written territorial demands to Bavaria and the other southern German states of Württemberg, Baden and Hesse-Darmstadt, which hastened the conclusion of defensive military alliances with these states.[15] France had been strongly opposed to any further alliance of German states, which would have significantly strengthened Prussia militarily.

The only result of French policy was the consent of Prussia to nominal independence for Saxony, Bavaria, Wurttemberg, Baden, and Hessia-Darmstadt, this was a small victory, and one without flavor for a French public that wanted territory and a French army that wanted revenge. The situation did not suit either France, which unexpectedly found itself next to the militarily powerful Prussian led North German Confederation, or Prussia, whose foremost objective was to complete the process of uniting the German states under its control. Thus, war between the two powers since 1866 was only a matter of time.

In Prussia, some officials considered a war against France both inevitable and necessary to arouse German nationalism in those states that would allow the unification of a great German empire. This aim was epitomized by Prussian Chancellor Otto von Bismarck's later statement: "I did not doubt that a Franco-German war must take place before the construction of a United Germany could be realised." Bismarck also knew that France should be the aggressor in the conflict to bring the four southern German states to side with Prussia, hence giving Germans numerical superiority. He was convinced that France would not find any allies in her war against Germany for the simple reason that "France, the victor, would be a danger to everybody – Prussia to nobody," and he added, "That is our strong point." Many Germans also viewed the French as the traditional destabilizer of Europe, and sought to weaken France to prevent further breaches of the peace.

The immediate cause of the war resided in the candidacy of Leopold of Hohenzollern-Sigmaringen, a Prussian prince, to the throne of Spain. France feared encirclement by an alliance between Prussia and Spain. The Hohenzollern prince's candidacy was withdrawn under French diplomatic pressure, but Otto von Bismarck goaded the French into declaring war by releasing an altered summary of the Ems Dispatch, a telegram sent by William I rejecting French demands that Prussia never again support a Hohenzollern candidacy. Bismarck's summary, as mistranslated by the French press Havas, made it sound as if the king had treated the French envoy in a demeaning fashion, which inflamed public opinion in France.

French historians François Roth and Pierre Milza argue that Napoleon III was pressured by a bellicose press and public opinion and thus sought war in response to France's diplomatic failures to obtain any territorial gains following the Austro-Prussian War. Napoleon III believed he would win a conflict with Prussia. Many in his court, such as Empress Eugénie, also wanted a victorious war to resolve growing domestic political problems, restore France as the undisputed leading power in Europe, and ensure the long-term survival of the House of Bonaparte. A national plebiscite held on 8 May 1870, which returned results overwhelmingly in favor of the Emperor's domestic agenda, gave the impression that the regime was politically popular and in a position to confront Prussia. Within days of the plebiscite, France's pacifist Foreign Minister Napoléon, comte Daru was replaced by Agenor, duc de Gramont, a fierce opponent of Prussia who, as French Ambassador to Austria in 1866, had advocated an Austro-French military alliance against Prussia. Napoleon III's worsening health problems made him less and less capable of reining in Empress Eugénie, Gramont and the other members of the war party, known collectively as the "mameluks". For Bismarck, the nomination of Gramont was seen as "a highly bellicose symptom".

The Ems telegram of 13 July 1870 had exactly the effect on French public opinion that Bismarck had intended. "This text produced the effect of a red flag on the Gallic bull", Bismarck later wrote. Gramont, the French foreign minister, declared that he felt "he had just received a slap." The leader of the monarchists in Parliament, Adolphe Thiers, spoke for moderation, arguing that France had won the diplomatic battle and there was no reason for war, but he was drowned out by cries that he was a traitor and a Prussian. Napoleon's new prime minister, Emile Ollivier, declared that France had done all that it could humanly and honorably do to prevent the war, and that he accepted the responsibility "with a light heart". A crowd of 15,000–20,000 people, carrying flags and patriotic banners, marched through the streets of Paris, demanding war. French mobilization was ordered early on 15 July. Upon receiving news of the French mobilization, the North German Confederation mobilized on the night of 15–16 July, while Bavaria and Baden did likewise on 16 July and Württemberg on 17 July. On 19 July 1870, the French sent a declaration of war to the Prussian government. The southern German states immediately sided with Prussia.

Napoleonic France had no documented alliance with other powers and entered the war virtually without allies. The calculation was for a victorious offensive, which, as the French Foreign Minister Gramont stated, was "the only way for France to lure the wary Austrians, Italians and Danes into the French alliance". The involvement of Russia on the side of France was not considered by her at all, since Russia made the lifting of restrictions on its naval construction on the Black Sea imposed on Russia by the Treaty of Paris (1856) following the Crimean War a precondition for the union. But Imperial France was not ready to do this. "Bonaparte did not dare to encroach on the Paris Treaty: the worse things turned out in the present, the more precious the heritage of the past became".

Opposing forces

The French Army consisted in peacetime of approximately 426,000 soldiers, some of them regulars, others conscripts who until March 1869 were selected by ballot and served for the comparatively long period of seven years. Some of them were veterans of previous French campaigns in the Crimean War, Algeria, the Franco-Austrian War in Italy, and in the Mexican campaign. However, following the "Seven Weeks War" between Prussia and Austria four years earlier, it had been calculated that, with commitments in Algeria and elsewhere, the French Army could field only 288,000 men to face the Prussian Army, when potentially 1,000,000 would be required. Under Marshal Adolphe Niel, urgent reforms were made. Universal conscription and a shorter period of service gave increased numbers of reservists, who would swell the army to a planned strength of 800,000 on mobilisation. Those who for any reason were not conscripted were to be enrolled in the Garde Mobile, a militia with a nominal strength of 400,000. However, the Franco-Prussian War broke out before these reforms could be completely implemented. The mobilisation of reservists was chaotic and resulted in large numbers of stragglers, while the Garde Mobile were generally untrained and often mutinous.

French infantry were equipped with the breech-loading Chassepot rifle, one of the most modern mass-produced firearms in the world at the time, with 1,037,555 available in French inventories. With a rubber ring seal and a smaller bullet, the Chassepot had a maximum effective range of some 1,500 metres (4,900 ft) with a short reloading time. French tactics emphasised the defensive use of the Chassepot rifle in trench-warfare style fighting—the so-called feu de bataillon. The artillery was equipped with rifled, muzzle-loaded La Hitte guns. The army also possessed a precursor to the machine-gun: the mitrailleuse, which could unleash significant, concentrated firepower but nevertheless lacked range and was comparatively immobile, and thus prone to being easily overrun. The mitrailleuse was mounted on an artillery gun carriage and grouped in batteries in a similar fashion to cannon.

The army was nominally led by Napoleon III, with Marshals François Achille Bazaine and Patrice de MacMahon in command of the field armies.[34] However, there was no previously arranged plan of campaign in place. The only campaign plan prepared between 1866 and 1870 was a defensive one.

The German army comprised that of the North German Confederation led by the Kingdom of Prussia, and the South German states drawn in under the secret clause of the preliminary peace of Nikolsburg, 26 July 1866,[35] and formalised in the Treaty of Prague, 23 August 1866.

Recruitment and organisation of the various armies were almost identical, and based on the concept of conscripting annual classes of men who then served in the regular regiments for a fixed term before being moved to the reserves. This process gave a theoretical peace time strength of 382,000 and a wartime strength of about 1,189,000.

German tactics emphasised encirclement battles like Cannae and using artillery offensively whenever possible. Rather than advancing in a column or line formation, Prussian infantry moved in small groups that were harder to target by artillery or French defensive fire.The sheer number of soldiers available made encirclement en masse and destruction of French formations relatively easy.

The army was equipped with the Dreyse needle gun renowned for its use at the Battle of Königgrätz, which was by this time showing the age of its 25-year-old design. The rifle had a range of only 600 m (2,000 ft) and lacked the rubber breech seal that permitted aimed shots. The deficiencies of the needle gun were more than compensated for by the famous Krupp 6-pounder (6 kg despite the gun being called a 6-pounder, the rifling technology enabled guns to fire twice the weight of projectiles in the same calibre) steel breech-loading cannons being issued to Prussian artillery batteries. Firing a contact-detonated shell, the Krupp gun had a longer range and a higher rate of fire than the French bronze muzzle loading cannon, which relied on faulty time fuses.

The Prussian army was controlled by the General Staff, under Field Marshal Helmuth von Moltke. The Prussian army was unique in Europe for having the only such organisation in existence, whose purpose in peacetime was to prepare the overall war strategy, and in wartime to direct operational movement and organise logistics and communications. The officers of the General Staff were hand-picked from the Prussian Kriegsakademie (War Academy). Moltke embraced new technology, particularly the railroad and telegraph, to coordinate and accelerate mobilisation of large forces.
