The Second French Intervention in Mexico (Spanish: Segunda intervención francesa en México, 1861–1867; known as Expédition du Mexique in France at the time and today as Intervention française au Mexique), also known as the Second Franco-Mexican War and the Mexican Adventure, was an invasion of Mexico, launched in late 1861, by the Second French Empire (1852–1870). Initially supported by the United Kingdom and Spain, the French intervention in Mexico was a consequence of Mexican President Benito Juárez's imposition of a two-year moratorium of loan-interest payments from July 1861 to French, British, and Spanish creditors. To extend the influence of Imperial France, Napoleon III instigated the intervention in Mexico by claiming that the military adventure was a foreign policy commitment to free trade. The establishment of a European-derived monarchy in Mexico would ensure European access to Mexican resources, particularly French access to Mexican silver. To realize his ambitions without interference from other European nations, Napoleon III of France entered into a coalition with the United Kingdom and Spain.

On 31 October 1861, France, the United Kingdom, and Spain agreed to the Convention of London, a joint effort to ensure that debt repayments from Mexico would be forthcoming. On 8 December 1861, the three navies disembarked their troops at the port city of Veracruz, on the Gulf of Mexico. When the British and the Spanish discovered that France had an ulterior motive and unilaterally planned to seize Mexico, they peacefully negotiated an agreement with Mexico to settle the debt issues. Simultaneously, Britain and Spain withdrew from the military coalition agreed to in London, and recalled their forces from Mexico. The subsequent French invasion took Mexico City and created the Second Mexican Empire (1861–1867), a client state of the French Empire. Many nations proceeded to acknowledge the political legitimacy of the newly created nation state.[9]

In Mexican politics, the French intervention allowed active political reaction against the liberal policies of social and socio-economic reform of president Benito Juárez (1858–1872), thus the Mexican Catholic Church, upper-class conservatives, much of the Mexican nobility, and some Native American communities welcomed and collaborated with the French empire's installation of Maximilian von Habsburg as Emperor of Mexico.[10] In European politics, the French intervention in Mexico reconciled the Second French Empire and the Austrian Empire, whom the French had defeated in the Franco-Austrian War of 1859. French imperial expansion into Mexico counterbalanced the geopolitical power of the Protestant Christian United States, by developing a powerful Catholic empire in Latin America, and the exploitation of the mineral wealth of the Mexican north-west. After much guerrilla warfare that continued after the Capture of Mexico City in 1863 – the French Empire withdrew from Mexico and abandoned the Austrian emperor of Mexico; subsequently, the Mexicans executed Emperor Maximilian I, on 19 June 1867, and restored the Mexican Republic.[10]

French invasion

The fleets of the Tripartite Alliance arrived at Veracruz between 8 and 17 December 1861, intending to pressure the Mexican government into settling its debts.[11] The Spanish fleet seized San Juan de Ulúa and subsequently the capital Veracruz[11] on 17 December. The European forces advanced to Orizaba, Cordoba and Tehuacán, as they had agreed in the Convention of Soledad.[11] The city of Campeche surrendered to the French fleet on 27 February 1862, and a French army, commanded by Charles de Lorencez, arrived on 5 March. The Mexican Minister of Foreign Affairs, Manuel Doblado met with the Spanish general Juan Prim (who was the nominal commander of the tripartite alliance) and explained to him the country's economic complications and persuaded him that the suspension of the debts was only going to be temporary. For the governments of Spain and Great Britain this explanation was sufficient, and along with their realisation of the French ambition to conquer Mexico, the two governments made the decision to peacefully withdraw their forces on 9 April, with the last British and Spanish troops leaving on 24 April without a shot being fired by either army. In May, the French man-of-war Bayonnaise blockaded Mazatlán for a few days.

Mexican forces commanded by General Ignacio Zaragoza managed to win an unexpected victory against the French army in the Battle of Puebla on 5 May 1862 (commemorated by the Cinco de Mayo holiday) halting the French advance for some time. The pursuing Mexican army was contained by the French at Orizaba, Veracruz, on 14 June. More French troops arrived on 21 September, and General Bazaine arrived with French reinforcements on 16 October. The French occupied the port of Tampico on 23 October, and unopposed by Mexican forces took control of Xalapa, Veracruz on 12 December.[12]

Capture of Mexico City by the French

The French bombarded Veracruz on 15 January 1863. Two months later, on 16 March, General Forey and the French Army began the siege of Puebla.

On 30 April, the French Foreign Legion earned its fame in the Battle of Camarón (or Camerone in French), when an infantry patrol unit of 62 soldiers and three officers, led by the one-handed Captain Jean Danjou, was attacked and besieged by Mexican infantry and cavalry units numbering three battalions, about 3000 men. They were forced to make a defence in a nearby hacienda. Danjou was mortally wounded at the hacienda, and his men mounted an almost suicidal bayonet attack, fighting to nearly the last man; only three French Legionnaires survived. To this day, the anniversary of 30 April remains the most important day of celebration for Legionnaires.

Entry of the French division in the Bay of Acapulco, 10 January 1863

The French army of General François Achille Bazaine defeated the Mexican army led by General Comonfort in its campaign to relieve the siege of Puebla, at San Lorenzo, to the south of Puebla. Puebla surrendered to the French shortly afterward, on 17 May. On 31 May, President Juárez fled the city with his cabinet, retreating northward to Paso del Norte and later to Chihuahua. Having taken the treasure of the state with them, the government-in-exile remained in Chihuahua until 1867.

French troops under Bazaine entered Mexico City on 7 June 1863. The main army entered the city three days later led by General Forey. General Almonte was appointed the provisional President of Mexico on 16 June, by the Superior Junta (which had been appointed by Forey). The Superior Junta with its 35 members met on 21 June and proclaimed a Catholic Empire on 10 July. The crown was offered to Maximilian, following pressures by Napoleon. Maximilian accepted the crown on 3 October, at the hands of the Comisión Mexicana, sent by the Superior Junta.

Arrival of Maximilian

Emperor Maximilian I of Mexico

On 28 and 31 March 1864, men from the French man-of-war Cordelière tried to take Mazatlán, but were initially repelled by Mexicans commanded by Colonel Gaspar Sánchez Ochoa.

The French under Bazaine occupied Guadalajara on 6 January 1864, and troops under Douay occupied Zacatecas on 6 February. Further decisive French victories continued with the fall of Acapulco on 3 June, occupation of Durango on 3 July, and the defeat of republicans in the states of Sinaloa and Jalisco in November.

Maximilian formally accepted the crown on 10 April, signing the Treaty of Miramar, and landed at Veracruz on 28 May (or possibly 29 May) 1864 in the SMS Novara. He was enthroned as Maximilian, Emperor of Mexico, with his wife Charlotte of Belgium, known by the Spanish form of her name, Carlota. In reality, Maximilian was a puppet monarch of the Second French Empire.

Maximilian expressed progressive European political ideas, favouring the establishment of a limited monarchy sharing powers with a democratically elected congress. He inspired passage of laws to abolish child labour, limit working hours, and abolish a system of land tenancy that virtually amounted to serfdom among the Indians. This was too liberal to please Mexico's conservatives, and the nation's liberals refused to accept a monarch, leaving Maximilian with few enthusiastic allies within Mexico.

On Sunday, 13 November 1864, three French men-of-war (Victoire, D'Assas and Diamante) shelled Mazatlán 13 times, and Imperial Mexican forces under Manuel Lozada entered and captured the city.

Early Republican victories

Benito Juárez, Republican leader and President

The French continued with victories in 1865, with Bazaine capturing Oaxaca on 9 February (defeating the city's defenders under General Porfirio Díaz). The French fleet landed soldiers who captured Guaymas on 29 March.

But on 11 April, republicans defeated Imperial forces at Tacámbaro in Michoacán. In April and May the republicans had many forces in the states of Sinaloa and Chihuahua. Most towns along the Rio Grande were also occupied by republicans. Throughout the country, the French were now harassed by guerrilla warfare, the kind of fighting that Mexican forces were already veterans at.

The decree known as the "Black Decree" was issued by Maximilian on 3 October, which threatened any Mexican captured in the war with immediate execution. The decree lead to around 11,000 executions. This was later the basis for the next government to order his own execution. Several high-ranking republican officials were executed under this order on 21 October.

U.S. diplomacy and involvement

As early as 1859, U.S. and Mexican efforts to ratify the McLane-Ocampo Treaty had failed in the bitterly divided U.S. Senate, where tensions were high between the North and the South over slavery issues. Such a treaty would have allowed U.S. construction in Mexico and protection from European forces in exchange for a payment of $4 million to the heavily indebted government of Benito Juárez. On 3 December 1860, President James Buchanan had delivered a speech stating his displeasure at being unable to secure Mexico from European interference:

European governments would have been deprived of all pretext to interfere in the territorial and domestic concerns of Mexico. We should have thus been relieved from the obligation of resisting, even by force, should this become necessary, any attempt of these governments to deprive our neighboring Republic of portions of her territory, a duty from which we could not shrink without abandoning the traditional and established policy of the American people.[13]

United States policy did not change during the French occupation as it had to use its resources for the American Civil War, which lasted 1861 to 1865. President Abraham Lincoln expressed his sympathy to Latin American republics against any European attempt to establish a monarchy. Shortly after the establishment of the Imperial government in April 1864, United States Secretary of State William H. Seward, while maintaining U.S. neutrality, expressed U.S. discomfort at the imposition of a monarchy in Mexico: "Nor can the United States deny that their own safety and destiny to which they aspire are intimately dependent on the continuance of free republican institutions throughout America."[14]

On 4 April 1864, Congress passed a joint resolution:

Resolved, &c., That the Congress of the United States are unwilling, by silence, to leave the nations of the world under the impression that they are indifferent spectators of the deplorable events now transpiring in the Republic of Mexico; and they therefore think fit to declare that it does not accord with the policy of the United States to acknowledge a monarchical government, erected on the ruins of any republican government in America, under the auspices of any European power.[15]

Near the end of the American Civil War, representatives at the 1865 Hampton Roads Conference briefly discussed a proposal for a north–south reconciliation by a joint action against the French in Mexico. In 1865, through the selling of Mexican bonds by Mexican agents in the United States, the Juarez Administration raised between $16-million and $18-million dollars for the purchase of American war material.[16] Between 1865 and 1868, General Herman Sturm acted as an agent to deliver guns and ammunition to the Mexican Republic led by Juarez.[17] In 1866 General Philip Sheridan was in charge of transferring additional supplies and weapons to the Liberal army, including some 30,000 rifles directly from the Baton Rouge Arsenal in Louisiana.[18]

By 1867, Seward shifted American policy from thinly veiled sympathy to the republican government of Juárez to open threat of war to induce a French withdrawal. Seward had invoked the Monroe Doctrine and later stated in 1868, "The Monroe Doctrine, which eight years ago was merely a theory, is now an irreversible fact."[19]

French withdrawal and Republican victories

Battle of Miahuatlán, 3 October 1866

In 1866, choosing Franco-American relations over his Mexican monarchy ambitions, Napoleon III announced the withdrawal of French forces beginning 31 May. The Republicans won a series of crippling victories taking immediate advantage of the end of French military support to the Imperial troops, occupying Chihuahua on 25 March,[20] taking Guadalajara on 8 July,[21] further capturing Matamoros, Tampico and Acapulco in July.[21] Napoleon III urged Maximilian to abandon Mexico and evacuate with the French troops. The French evacuated Monterrey on 26 July,[21] Saltillo on 5 August,[21] and the whole state of Sonora in September.[21] Maximilian's French cabinet members resigned on 18 September.[21] The Republicans defeated imperial troops in the Battle of Miahuatlán in Oaxaca in October, occupying the whole of Oaxaca in November, as well as parts of Zacatecas, San Luis Potosí and Guanajuato. The combined Austro-Belgian Volunteer Corps was formally disbanded at the end of 1866. Approximately 1,000 of these Austrian and Belgian volunteers chose to enlist in Maximilian's Imperial Army while the remaining 3,428 embarked for Europe.[22] The separate Belgian Legion was also dissolved in December 1866 and 754 returned to their homeland.[23]

On 13 November, Ramón Corona and the French agreed to terms for the withdrawal of the latter forces from Mazatlán. At noon, the French boarded three men-of-war, Rhin, Marie and Talisman and departed Mexico defeated.

Republican triumph, execution of Maximilian

The Republicans occupied the rest of the states of Zacatecas, San Luis Potosí and Guanajuato in January. The French evacuated the capital on 5 February.

On 13 February 1867, Maximilian withdrew to Querétaro. The Republicans began a siege of the city on 9 March, and Mexico City on 12 April. An imperial sortie from Querétaro failed on 27 April.

On 11 May, Maximilian resolved to try to escape through the enemy lines. He was intercepted on 15 May. Following a court-martial, he was sentenced to death. Many of the crowned heads of Europe and other prominent figures (including liberals Victor Hugo and Giuseppe Garibaldi) sent telegrams and letters to Mexico pleading for Maximilian's life to be spared, but Juárez refused to commute the sentence. He believed he had to send a strong message that Mexico would not tolerate any government imposed by foreign powers.

Maximilian was executed on 19 June (along with his generals Miguel Miramón and Tomás Mejía) on the Cerro de las Campanas, a hill on the outskirts of Querétaro, by the forces loyal to President Benito Juárez, who had kept the federal government functioning during the French intervention. Mexico City surrendered the day after Maximilian was executed.

The republic was restored, and President Juárez was returned to power in the national capital. He made few changes in policy, given that the progressive Maximilian had upheld most of Juárez's liberal reforms.

After the victory, the Conservative party was so thoroughly discredited by its alliance with the invading French troops that it effectively became defunct. The Liberal party was almost unchallenged as a political force during the first years of the "restored republic". In 1871, however, Juárez was re-elected to yet another term as president in spite of a constitutional prohibition of re-elections. The French intervention had ended with the Republican lead government being more stable and both internal and external forces were now kept at bay.

Porfirio Díaz (a Liberal general and a hero of the French war, but increasingly conservative in outlook), one of the losing candidates, launched a rebellion against the president. Supported by conservative factions within the Liberal party, the attempted revolt (the so-called Plan de la Noria) was already at the point of defeat when Juárez died in office on 19 July 1872, making it a moot point. Díaz ran against interim president Sebastián Lerdo de Tejada, lost the election, and retired to his hacienda in Oaxaca. Four years later, in 1876, when Lerdo ran for re-election, Díaz launched a second, successful revolt (the Plan de Tuxtepec) and captured the presidency. He held it through eight terms until 1911 now known as the Porfiriato, a period when he jailed many political opponents at the fort off Veracruz, heavily industrialized Mexico helping elites and hurting the poor, and practically ran a dictatorship.

As for Napoleon's empire, it would later collapsed in 1870, just three years later, during the Franco-Prussian war. His adventure in Mexico had improved relations with Austria through Maximilian but produced no result as France had alienated itself in the international community.

This unit was commonly designated as the "Egyptian Battalion". It consisted of 453 men (including troops recruited from the Sudan), who were placed under the command of French commandant Mangin of the 3rd Zouave Regiment. Operating effectively in the Veracruz region, the Corps suffered 126 casualties until being withdrawn to Egypt in May 1867.[31] Maximilian protested the loss of the Egyptian Corps, ostensibly to suppress a rebellion in the Sudan, because they were "extremely helpful in the hot lands".[32]
