The Battle of Puebla: a victory between two interventions
The Battle of Puebla on May 5, 1862, ended with Ignacio Zaragoza's Mexican army repelling a French assault. The forts of Loreto and Guadalupe guarded the approaches to a city on the route between Veracruz and Mexico City. Their defenders prevented the invading force from taking Puebla that day. The victory became the event commemorated as Cinco de Mayo. It was followed by a renewed French campaign, the capture of Puebla in 1863, and the establishment of an empire under Maximilian of Habsburg.
Mexico's civil conflict had left the national government with heavy debts and limited means to pay them. Liberal forces supporting Benito Juárez captured Mexico City in January 1861 after a struggle against Conservative opponents. Juárez then suspended foreign debt payments for two years. Britain, Spain, and France concluded an agreement in London to intervene and recover the money. Their forces reached Veracruz. The British and Spanish eventually withdrew, while Napoleon III pursued a larger French objective: replacing the republic with a government favorable to French interests.
The advance inland made Puebla strategically important. Its position connected the Gulf port with the capital, and its elevated religious buildings offered places that could be fortified. Loreto had begun as a chapel in the 1600s. Construction of the fort around it began in 1815 and ended in 1817. The resulting enclosure had a square plan with four bastions named San José, El Carmen, Santa Bárbara, and Guadalupe. Barracks, the chapel, a chaplain's house, and a cistern formed parts of the complex.
Guadalupe also developed from a religious foundation. Its church stood on high ground from which movements toward the city could be observed. Fortification work began in 1816. Before the French attack in 1862, engineer Joaquín Colombres strengthened the position by improving its ditches and adapting the steep hillside for defense. The two fortified heights became central to Zaragoza's preparations. From headquarters at the church and convent of Nuestra Señora de los Remedios, he directed officers including Felipe Berriozábal, Francisco Lamadrid, Miguel Negrete, Antonio Álvarez, and Porfirio Díaz.
The French commander, the Count of Lorencez, chose to attack Guadalupe. Zaragoza reinforced the defensive line between the two forts to prevent the positions from being turned from behind. French columns advanced toward the heights, but repeated attempts failed to break through. Fighting also extended toward Xonaca, where troops commanded by Díaz checked another advance. Lorencez formed a further column in the afternoon and sent it against Guadalupe without success. The French finally withdrew. The Battle of Puebla had preserved the city's defenses against the first invasion force.
Napoleon III responded by sending a stronger expedition under General Élie Frédéric Forey. It attacked Puebla in March 1863. Zaragoza had died in September 1862, and Jesús González Ortega now commanded the defense. After resisting for two months, the city surrendered. Juárez moved his government to San Luis Potosí and called for continued resistance. The French advance had gained the route to the capital, but the republican government continued operating outside it. The struggle shifted from defending Puebla to sustaining resistance across a wider territory.
Maximilian arrived in Mexico in 1864 to head the Second Empire. His government and Juárez's republic existed simultaneously, with different territories and supporters. The American Civil War had limited Washington's response to the intervention. Secretary of State William Henry Seward initially avoided a direct confrontation that might encourage French assistance to the Confederacy. Mexico's representative in the United States, Matías Romero, worked to build support for the republic. After the Civil War ended, American backing for Juárez increased as republican forces also gained ground.
The intervention became costly and unpopular in France. Napoleon III ordered a withdrawal in 1866, and French troops departed during the following year. Maximilian's imperial project collapsed, and the republic was restored in 1867. The Battle of Puebla belonged to the opening stage of this longer conflict. Its outcome and the later French capture of the city were different events, separated by renewed preparation and a larger expedition. Mexican resistance continued through both the loss of the capital and the years of imperial government.
Loreto later served other military purposes and became a museum in 1936. On May 5, 1962, the centenary of the battle, it took the name Museum of Non-Intervention. Its collections include uniforms, flags, documents, and objects connected with the conflicts that shaped the site. Restoration of the forts area also began in the centenary year, preserving Guadalupe and its surroundings. The former churches and defensive works became places of public remembrance, retaining the terrain and buildings at the center of the Battle of Puebla.
