Mexican War of Independence

Monte de las Cruces was one of the pivotal engagements of the early Mexican War of Independence, fought in October 1810. The battle brought together the principal insurgent commanders — Hidalgo, Allende, Aldama, and Abasolo — against a substantially smaller Royalist force under Agustín Iturbide. The disparity in force sizes was stark: the insurgents fielded between 60,000 and 80,000 fighters against a Royalist contingent estimated at between 1,400 and 7,000. Despite that numerical advantage, insurgent casualties — between 3,000 and 5,000 — were comparable in scale to Royalist losses of 1,000 to 2,500, underscoring the limitations of the largely irregular insurgent force against trained Royalist troops. The battle's place in the early independence struggle stems from its timing and the concentration of the movement's leadership, marking a moment when the insurgency tested its capacity to engage organized Royalist resistance in open confrontation.

The Battle of Calderón Bridge was a decisive engagement in the Mexican War of Independence, fought on the banks of the Calderón River approximately 60 kilometers east of Guadalajara. The insurgent force under Hidalgo, Allende, Aldama, and Abasolo numbered around 35,000 but suffered casualties estimated between 1,200 and 13,000, against roughly 1,000 on the royalist side commanded by Calleja del Rey, whose force was substantially smaller at 5,000–8,000 troops. The scale of the disparity in losses relative to force sizes points to a significant royalist military advantage in discipline or firepower. The battle's designation as decisive marks it as a turning point that curtailed the early insurgent momentum that had built around Hidalgo's movement since 1810, shifting the operational balance in favor of the Crown in the central conflict of the independence struggle.

The Battle of El Maguey, fought on 2 May 1811 in Aguascalientes, was a royalist victory over Mexican rebel forces commanded by Ignacio López Rayón. The engagement pitted a Spanish force of 3,000 troops under General Miguel Emparan against independence fighters at a moment when the broader Mexican War of Independence was still in early contest. A royalist victory at El Maguey reinforced Spanish military pressure on rebel leadership in the region, keeping crown forces in a dominant operational position in this part of the country during a critical phase of the independence struggle.

The Battle of El Veladero, fought at Cerro El Veladero near Acapulco de Juárez, resulted in a victory for the Mexican rebel forces over royalist troops loyal to the Spanish crown. The engagement placed José María Morelos and his co-commanders in the field around a strategically significant coastal position, demonstrating the reach of the independence movement into the Pacific coast region. As part of the broader War of Mexican Independence, the rebel success at El Veladero contributed to insurgent pressure on royalist control in the south, an area where Morelos would continue to operate as one of the conflict's central military figures.

The Battle of Llanos de Santa Juana was a royalist victory in the Colima region during the Mexican War of Independence. Fought between royalist forces under Colonel Manuel del Río and insurgents under General José Calixto Martínez y Moreno, the engagement resulted in a defeat for the Mexican rebel force, which sustained approximately 300 casualties from a force of around 1,000. The outcome reinforced Spanish control in the area around what is now Cuauhtémoc, Colima, checking insurgent expansion in that region at a period when the independence movement was facing significant military pressure across multiple fronts.

The Battle of Puerto de Piñones, fought on 1 April 1811 in Coahuila, was a rebel victory during the Mexican War of Independence. Forces under Ignacio López Rayón defeated the royalist command of José Manuel de Ochoa, demonstrating that insurgent operations could achieve battlefield success against Crown forces in the northern regions of New Spain. The engagement occurred in the broader context of the independence struggle that had begun the previous year, contributing to the sustained pressure rebels maintained on royalist military authority across the territory.

The Battle of Escamela, fought in the Veracruz region near Ixtaczoquitlán, resulted in a victory for the Mexican rebel forces under commanders including José María Morelos y Pavón and Hermenegildo Galeana against royalist forces loyal to the Spanish crown. The engagement was part of the broader insurgent campaign in the Veracruz theater during the War of Mexican Independence, a conflict that had been underway since the early 1810s. A rebel success in this region would have contributed to insurgent pressure on royalist control of the Gulf coast corridor, an area of strategic importance for Spanish imperial logistics and communication.

The Battle of Izúcar took place on 23 February 1812 near Izúcar de Matamoros, Puebla, as part of the broader insurgent campaign during the Mexican War of Independence. The engagement pitted royalist forces under Ciriaco del Llano against rebel forces commanded by Mariano Matamoros y Guridi, one of the prominent insurgent leaders of the period. The battle represents one of the localized confrontations through which independence forces sought to contest royalist control in the Puebla region. Beyond establishing the presence of both commands at this location, the recorded outcome and its operational consequences remain unclear from available sources.

The Battle of Tecualoya, fought in January 1812 in the canyons of Tecualoya, resulted in a decisive defeat for the Mexican insurgent force under Hermenegildo Galeana. The loss was materially significant: Galeana's army was stripped of its entire artillery complement, a serious blow to rebel operational capacity at a stage of the Mexican War of Independence when such equipment was difficult to replace. The defeat was not permanent in its material consequences, however. The insurgents subsequently recovered the lost field pieces at the Battle of Tenancingo, where royalist commander José María Oviedo was killed in action. The engagement thus represents one episode in the shifting fortunes of the independence struggle in central Mexico during 1812, illustrating both the vulnerability of insurgent forces to royalist pressure and their capacity to reverse materiel losses through continued campaigning.

The Battle of Tenango del Valle took place in May 1812 on the outskirts of Tenango del Valle in what is now the State of Mexico, during the broader insurgency against Spanish colonial rule. The engagement pitted royalist forces loyal to the Spanish crown against Mexican rebels seeking independence, with Ignacio López Rayón commanding the insurgent side. Beyond establishing that the battle occurred during this period of active insurgent operations, the available record does not detail its outcome or its specific effect on the wider independence campaign.

The Battle of Zitlala, fought on 4 July 1812 near Zitlala in present-day Guerrero, was a victory for the Mexican rebel forces over royalist troops loyal to the Spanish crown during the War of Mexican Independence. The engagement was part of the broader insurgent campaign in the southern regions of New Spain, where commanders including José María Morelos y Pavón and Hermenegildo Galeana were active in contesting royalist control. A rebel victory in this area contributed to sustaining insurgent momentum in Guerrero at a stage of the independence struggle when control of southern territory was contested between crown and rebel forces.

The Battle of Zitácuaro, fought on 2 January 1812 near Zitácuaro, Michoacán, resulted in a royalist victory despite the insurgent force under Ignacio López Rayón outnumbering Félix María Calleja's Spanish troops by a substantial margin. The outcome demonstrated that numerical superiority alone did not translate into battlefield success for the Mexican rebel cause at this stage of the War of Independence. A royalist victory under such odds reinforced Spanish imperial control in Michoacán and dealt a setback to the insurgent leadership operating in the region during a critical period of the conflict.

The Capture of Oaxaca on 25 November 1812 was a victory for the Mexican insurgent forces under José María Morelos y Pavón over the royalist garrison commanded by Antonio Pío González-Saravia Mollinedo. Morelos commanded a force of approximately 5,000 insurgents against a royalist force of around 2,000, and the engagement secured the city of Oaxaca for the independence movement. The fall of Oaxaca represented a significant territorial gain in southern New Spain, extending insurgent control into a strategically and economically important regional center. The victory reinforced Morelos's position as the leading military figure of the independence cause following Miguel Hidalgo's death, demonstrating the insurgency's capacity to take and hold major urban centers against organized royalist resistance.

The Capture of Orizaba on 28 October 1812 resulted in a victory for the Mexican rebel forces under José María Morelos y Pavón over royalist forces commanded by General José Antonio Andrade. The engagement demonstrated the rebels' capacity to contest and seize significant population centers in the Veracruz region, extending insurgent reach beyond their earlier areas of operation. With a reported force of 10,000, Morelos and his subordinate Hermenegildo Galeana applied substantial pressure on royalist control in the area, adding Orizaba to the string of operations that characterized Morelos's active campaign period during 1812.

The Battle of La Chincúa, fought from April 19 through May 28, 1813, at a ranch at Tonalá, Chiapas, produced a victory for the Mexican rebel forces under Mariano Matamoros y Guridi against the royalist army commanded by General Miguel Dambrini. The engagement extended over roughly six weeks, indicating sustained pressure rather than a single decisive engagement. Within the broader Mexican War of Independence, rebel successes in southern regions such as Chiapas helped contest royalist control beyond the central heartland, demonstrating the geographic reach of the independence movement by 1813.

The Battle of Lomas de Santa María was fought in December 1813 near Valladolid as part of the broader insurgent campaign during the Mexican War of Independence. The engagement brought together several of the rebellion's most prominent commanders — Morelos, Matamoros, Bravo, and Galeana — against royalist forces under Iturbide, Calleja, and del Llano. Despite holding a considerable numerical advantage with roughly 5,600 fighters against approximately 1,200 royalists, the rebel forces suffered disproportionately higher casualties: 789 against an estimated 200 on the royalist side. The outcome, while not formally recorded, reflects the pattern of royalist tactical effectiveness in the later stages of the independence conflict, where disciplined professional forces repeatedly checked insurgent momentum despite being outnumbered.

The Battle of Medina ended the Gutiérrez–Magee Expedition, the principal republican effort to wrest Texas from Spanish authority during this phase of the Mexican War of Independence. Arredondo's forces, outnumbering the republican army, inflicted casualties of approximately 1,300 on a combined force of Tejano-Mexican and Tejano-American revolutionaries — losses amounting to nearly the entire republican strength engaged. The destruction of the Republican Army of the North effectively suppressed the independence movement in Texas and restored Spanish control over the region. Described as the deadliest battle in Texas history, the defeat eliminated the organized revolutionary presence that had briefly threatened San Antonio de Bexar and set back the cause of Texas independence by years.

The Battle of Tenancingo, fought on the outskirts of Tenancingo de Degollado in the State of Mexico, was a engagement during the Mexican War of Independence in which insurgent forces under José María Morelos y Pavón defeated royalist troops commanded by Rosendo Porlier y Asteguieta. The victory added to Morelos's record of battlefield successes against Spanish crown forces during the independence struggle, reinforcing the operational capacity of the rebel movement in central Mexico.

The Battle of Puruarán, fought in January 1814 near Puruarán, Michoacán, resulted in a royalist victory over insurgent forces commanded by Mariano Matamoros y Guridi. With the rebel force of roughly 1,000 sustaining casualties equal to that entire strength, the engagement effectively destroyed the insurgent contingent engaged. The loss of Matamoros as a field commander dealt a significant blow to the independence movement at a moment when royalist forces were pressing hard across Michoacán. One of the Spanish commanders at Puruarán, Agustín de Iturbide, would later switch allegiances and ultimately lead Mexico to independence, making the battle a notable early moment in his military career within the conflict.

The Battle of Temalaca, fought on 5 November 1815 near Temalaca, Puebla, ended in a royalist victory over the Mexican insurgent forces commanded by José María Morelos y Pavón. Morelos was one of the foremost military and political leaders of the independence movement, and his defeat and subsequent capture at Temalaca represented a severe blow to the rebel cause. The engagement effectively removed the most prominent organizing figure of the insurgency from the field, disrupting the coordination and momentum that the independence movement had built. Spanish forces under Manuel de la Concha secured a result that would have lasting consequences for the trajectory of the war well beyond a single engagement.

The Battle of Agua Zarca, fought on November 5, 1819, resulted in a royalist victory over insurgent forces under General Vicente Guerrero in the outskirts of Agua Zarca, Guerrero. Despite the defeat, Guerrero evaded capture by jumping off a cliff and concealing himself in the surrounding mountain range — terrain that would continue to shelter insurgent resistance in the region. The engagement underscores the pattern of the late Mexican War of Independence in the south, where royalist forces could win engagements without decisively eliminating insurgent leadership, and where local geography repeatedly enabled commanders like Guerrero to survive and sustain the rebellion. Guerrero's escape preserved one of the independence movement's key remaining commanders at a moment when royalist forces were pressing hard to extinguish organized resistance.

The Battle of Azcapotzalco, fought on August 19, 1821, near Mexico City, stands as one of the final military engagements of the Mexican War of Independence. Trigarante Army forces under colonels Anastasio Bustamante and Luis Quintanar faced a Spanish force commanded by Manuel de la Concha at a substantial numerical disadvantage of roughly 16,000 to 3,000 in favor of the insurgents. Coming just days before the conclusion of the war, the engagement reflected the collapsing capacity of Spanish imperial forces to resist the Trigarante campaign that had swept through New Spain since the Plan of Iguala earlier that year. Its proximity to Mexico City underscored how far royalist control had contracted by late August 1821.
