The Saint Patrick's Battalion (Spanish: Batallón de San Patricio), formed and led by John Riley, was a unit of 175 to several hundred immigrants (accounts vary) and expatriates of European descent who fought as part of the Mexican Army against the United States in the Mexican–American War of 1846–8. Most of the battalion's members had deserted or defected from the United States Army. The Battalion served as an artillery unit for much of the war. Despite later being formally designated as two infantry companies, it still retained artillery pieces throughout the conflict. In many ways, the battalion acted as the sole Mexican counterbalance to the recent U.S. innovation of horse artillery. The San Patricos were responsible for the toughest battles encountered by the United States in its invasion of Mexico, with Ulysses S. Grant remarking that "Churubusco proved to be about the severest battle fought in the valley of Mexico".
Composed primarily of Catholic Irish and German immigrants, the battalion also included Canadians, English, French, Italians, Poles, Scots, Spaniards, Swiss, and Mexican people, many of whom were members of the Catholic Church. Disenfranchised Americans were in the ranks, including escaped slaves from the Southern United States. Only a few members of the Saint Patrick's Battalion were actual U.S. citizens. The Mexican government printed propaganda in different languages to dissuade immigrants in the U.S. army of their cause and offered incentives to foreigners who would enlist in its army including; granting them citizenship, paying higher wages than the U.S. Army and the offer of generous land grants.
The San Patricos are revered and honoured in Mexico and Ireland, while remaining a largely unknown historical curiosity in the United States. Members of the Battalion are known to have deserted from U.S. Army regiments including; the 1st Artillery, the 2nd Artillery, the 3rd Artillery, the 4th Artillery, the 2nd Dragoons, the 2nd Infantry, the 3rd Infantry, the 4th Infantry, the 5th Infantry, the 6th Infantry, the 7th Infantry and the 8th Infantry.

For Americans of the generation that fought the Mexican–American War, the San Patricios were considered traitors. For Mexicans of that generation, and generations to come, the San Patricios were heroes who came to their aid in an hour of need. Successive Mexican presidents have praised the San Patricios; Vicente Fox Quesada stated that "The affinities between Ireland and Mexico go back to the first years of our nation, when our country fought to preserve its national sovereignty... Then, a brave group of Irish soldiers... in a heroic gesture, decided to fight against the foreign ground invasion", and Mexican president Ernesto Zedillo stated "Members of the St. Patrick's Battalion were executed for following their consciences. They were martyred for adhering to the highest ideals ... we honor their memory. In the name of the people of Mexico, I salute today the people of Ireland and express my eternal gratitude".
The great majority of these men were recent immigrants who had arrived at northeastern U.S. ports, part of the Irish diaspora then escaping the Great Irish Famine and extremely poor economic conditions in Ireland, part of the United Kingdom of Great Britain and Ireland at the time. The U.S. Army often recruited Irishmen and other immigrants into military service shortly or sometimes immediately after arrival to America in coffin ships, with promises of salaries and land after the war.
Numerous theories have been proposed as to their motives for desertion, including cultural alienation, mistreatment of immigrant soldiers by nativist soldiers and senior officers, brutal military discipline and dislike of service in the U.S. military, being forced to attend Protestant church services and being unable to practice their Catholic religion freely as well as religious ideological convictions, the incentive of higher wages and land grants starting at 320 acres (1.3 km2) offered by Mexico, and viewing the U.S. invasion of Mexico as unjust.
It is believed primary motivations were shared religion with the Mexicans and sympathy for the Mexican cause based on similarities between the situations in Mexico and Ireland. This hypothesis is based on evidence of the number of Irish Catholics in the Battalion, the letters of John Riley, and the field entries of senior officers. Another hypothesis is that the members of the Saint Patrick's Battalion had been unhappy with their treatment in the U.S. Army; this was the conviction of George Ballentine, an Englishman who served in the American army. Ballentine stated that while "there was a portion of truth" in the view—commonly assigned by officers—that the deserters joined the Mexican army due to their Catholicism, "I have good reason to believe, in fact in some cases I know, that harsh and unjust treatment by their officers operated far more strongly than any other consideration to produce the deplorable result [desertion]," describing how he found the punishments used for "trivial offensives" to be "revolting and disgusting". Another theory some historians hold is that the soldiers were attracted by the incentives offered by the Mexican government: safe passage throughout Mexico for deserters, generous land grants, and the offer of potential military commissions. For poor people coming from famine conditions, economics was often an important incentive.
Mexican author José Raúl Conseco noted that many Irish lived in northern Texas, and were forced to move south due to regional insecurity. Mainly Irish settlers from San Patricio, Texas had previously sided with Mexican forces against Texan rebels at the Battle of Lipantitlán in the Texan Revolution.
Irish expatriates had a long tradition of serving in military forces of Catholic countries, for instance, serving with Spain and later France in groups of young men who had left Ireland during what would become known as the Flight of the Wild Geese in the 17th century. In addition, many Irish fought as soldiers in South American wars of independence.[c]
There are conflicting accounts of the design of the flag of the Saint Patrick's Battalion. No flags or depictions of them are known to have survived to the present day. The only version of the flag known to have survived the war was subsequently lost or stolen from the chapel at West Point.
John Riley, who left an account of the battalion, noted the flag in a letter:
|“||In all my letter, I forgot to tell you under what banner we fought so bravely. It was that glorious Emblem of native rights, that being the banner which should have floated over our native Soil many years ago, it was St. Patrick, the Harp of Erin, the Shamrock upon a green field.||”|
—John Riley, 
According to an American journalist covering the war with Mexico:
|“||The banner is of green silk, and on one side is a harp, surmounted by the Mexican coat of arms, with a scroll on which is painted Libertad por la Republica Mexicana [Liberty for the Mexican Republic]. Under the harp is the motto of Erin go Bragh! On the other side is a painting ... made to represent St. Patrick, in his left hand a key and in his right a crook or staff resting upon a serpent. Underneath is painted San Patricio.||”|
Two other eye-witness accounts of the flag exist, both from American soldiers. The first describes it as:
|“||...a beautiful green silk banner [which] waved over their heads; on it glittered a silver cross and a golden harp, embroidered by the hands of the fair nuns of San Luis Potosí.||”|
The second notes only:
|“||Among the mighty host we passed was O'Reilly [sic] and his company of deserters bearing aloft in high disgrace the holy banner of St. Patrick."||”|
A radically different version of the flag was described in this Mexican source:
|“||Tenían una insignia blanca, en la que se encontraban los escudos de Irlanda y Mexico, y el nombre de su capitán, John O'Reilly bordado en verde. [They had a white flag/standard, on which were found the shields of Ireland and Mexico, and the name of their captain, John O'Reilly [sic] embroidered in green.]||”|
—Diccionario Porrúa de historia, biografía y geografía de México | (3:3146)
Whatever the case, in 1997 a reproduction military flag was created by the Clifden and Connemara Heritage Group. Another was created the following year for the MGM film One Man's Hero. The film was a romanticised version of the San Patricios' history. A third version embodying the description of the San Luis Potosí flag was made for the Irish Society of Chicago, which hung it in Chicago's Union League Club.
Some theories suggest that the Saint Patrick's Battalion might have used different banners (as an artillery unit, an infantry company and as a reconstructed unit).
Service as a military unit
Formation and early engagements
Present in the Mexican Army for the battles of Palo Alto and Resaca de la Palma were the Legión de Extranjeros (Legion of Foreigners); the men who would later make up the core of the Saint Patrick's battalion. Meanwhile, deserters were abondoning General Taylor's army on the Rio Grande. Riley and "a company of 48 Irishmen" manned Mexican artillery at the Siege of Fort Texas, which took place concurrently to the two other battles. Martin Tritschler, German Mexican and a Captain at the Battle of Cerro Gordo, is attributed with convincing a large number of German soldiers to defect from the U.S. occupying forces in Puebla, Puebla.
The Saint Patrick's Battalion first fought as a recognised Mexican unit in the Battle of Monterrey on 21 September 1846, as an artillery battery. Popularly they were called Los Colorados by the Mexicans because of their ruddy, sun-burnt complexions and red hair color. They were commanded by John Riley,[b] an Irish artilleryman and veteran non-commissioned officer of the British Army, who possibly arrived in Canada in 1843 whilst serving in the British Army (the assertion that he served as a Sergeant in the 66th (Berkshire) Regiment of Foot, is known to be a inaccurate) going on to join the U.S. Army in Michigan in September 1845. He deserted in Matamoros in April 1846. Upon meeting Mexican forces he was initially given the Officer rank of Lieutenant by General Pedro de Ampudia.
At the battle of Monterrey the San Patricios proved their artillery skills by causing the deaths of many American soldiers, and they are credited with defeating two to three separate assaults into the heart of the city. Among their targets were companies led by such officers as Braxton Bragg, many of whose soldiers would end up in their own ranks later in the war. Their tenacity, however, did not affect the Mexican commanders' decision to capitulate and abandon the position.
Following the engagement at Monterrey, the San Patricios grew in number, by some estimates reaching an enlistment of over 700 men. Forces re-assembled at San Luis Potosí and they had their distinct green silk flag embroidered there.
They then marched northward after joining a larger force commanded by Antonio López de Santa Anna sent from Mexico City, the "liberating army of the North". At the Battle of Buena Vista (known as the battle of Angostura in Mexico) in Coahuila on 23 February, the Patricios became engaged with U.S. forces. They were assigned the three heaviest — 18 and 24 pound — cannons the Mexican army possessed, which were positioned on high ground over-looking the battlefield, at the base of a hillside (just below what is now a gravel mine). They were later described as "a strong Mexican battery ... moved ... by dint of extraordinary exertions ... [that] commanded the entire plateau".
They started the battle supporting Mexican infantry by firing on U.S. lines as the Mexicans advanced on them, then later decimating an artillery battery directly opposite them on the battlefield (Washington’s 4th Artillery, D Battery). A small number of San Patricios were dispatched with a division commanded by Manuel Lombardini with the express purpose of capturing the 4th's cannons once the crews had been dealt with. As the division got close enough they charged the artillery battery, bayoneting whoever remained and routing the rest, leaving the attached San Patricios free to haul away two six-pound cannons. These cannons would later be used by Mexican forces at the Battle of Contreras.
In frustration U.S. Commander Zachary Taylor, referring to the Saint Patrick's Battalion, ordered a squadron of the 1st Dragoons to "take that damned battery". In this task they failed, and, badly bloodied, were forced to retreat. At about 1 p.m. the San Patricios covered a Mexican retreat as a disordered mass of infantry sought refuge during a lull in the fighting. The San Patricios rode out the day in a costly artillery duel with several American batteries, which killed and injured roughly one third of them. General Francisco Mejia’s Battle Report for Buena Vista described the San Patricios’ as “worthy of the most consummate praise because the men fought with daring bravery.” Several Irishmen were awarded the War Cross by the Mexican government for their conduct in that battle, and many received field promotions.
Re-organization and final battles
Despite their excellent performance in a number of engagements as artillery, the much-reduced San Patricios were ordered to muster a larger infantry battalion in mid-1847 by personal order of Santa Anna. It was renamed the The Foreign Legion of Patricios and consisted of volunteers from many European countries, commanded by Col. Francisco R. Moreno, with Riley in charge of 1st company and Santiago O'Leary heading up the second. Desertion handbills were produced, specially targeting Catholic Irish, French and German immigrants in the invading U.S. army and stating that "You must not fight against a religious people, nor should you be seen in the ranks of those who proclaim slavery of mankind as a constitutive principle ... liberty is not on the part of those who desire to be lords of the world, robbing properties and territories which do not belong to them and shedding so much blood in order to accomplish their views, views in open war to the principles of our holy religion".
As an infantry unit, the San Patricios continued to serve with distinction. Knowing that they were likely to face the death penalty if captured, the San Patricios are known to have threatened wavering Mexican troops with death by "friendly fire" at the Battle of Cerro Gordo if they retreated. When the San Patricios were too heavily-engaged to carry out their threat, the Mexican troops broke and ran, leaving the San Patricios as they fought U.S. troops in hand-to-hand combat.
The Battle of Churubusco (20 August 1847) took place about four months after the defeat at Cerro Gordo. Gen. Santa Anna gave a verbal order to "preserve the point at all risk". The San Patricio Companies initially met the attackers outside the walls of the convent at a tête-de-pont, which was about 500 yards (457 m) from a fortified convent. A battery of three to five heavy cannons were used from this position to hold off the American advance along with support from Los Independencia Batallón and Los Bravos Batallón. The Americans were under the command of Col. William Hoffman. Several U.S. charges towards the bridgehead were thrown off, with the San Patricio companies serving as an example to the supporting battalions. Unlike the San Patricios, most of whom were veterans (many having served in the armies of the United Kingdom and various German states), the supporting Mexican battalions were simply militia (the term 'National Guard' is also used) who had been untested by battle.
A lack of ammunition led the Mexican soldiers in the trenches between the bridgehead and the convent to disband; without ammunition, they had no way to fight back. Santa Anna had ordered half of these soldiers to a different part of the battlefield. When the requested ammunition wagon finally arrived, the 9 ½ drachm cartridges were compatible with none but the San Patricio Companies "Brown Bess" muskets, and they made up only a fraction of the defending forces. Further hampering Mexican efforts, a stray spark from an artillery piece firing grape shot at the on-coming U.S. troops caused the just-arrived ammunition to explode and set fire to several men, including Captain O'Leary and Gen.l Anaya. A withdrawal behind the walls of the convento de Churubusco was called when the threat of being outflanked proved too great.
The San Patricios used this battle as a chance to settle old scores with U.S. troops. "The large number of officers killed in the affair was ... ascribed to them, as for the gratification of their revenge they aimed at no other objects during the engagement". At some point during the fighting for the convent, two American officers led fifteen men against a point in the Mexican defences, and mistook San Patrico members for friendly U.S. army troops; the San Patricos opened fire on them, killing and wounding all but one of the group. Though hopelessly outnumbered and under-equipped, the defenders repelled the attacking U.S. forces with heavy losses until their ammunition ran out and a Mexican officer raised the white flag of surrender. Officer Patrick Dalton of the San Patricios tore the white flag down, prompting Gen. Pedro Anaya to order his men to fight on, with their bare hands if necessary. American Private Ballentine reported that when the Mexicans attempted to raise the white flag two more times, members of the San Patricios shot and killed them. After brutal close-quarters fighting with bayonets and sabers through the halls and rooms inside the convent, U.S. Army Captain James M. Smith suggested a surrender after raising his white handkerchief. Following the U.S. victory, the Americans "ventilat[ed] their vocabulary of Saxon expletives, not very "courteously," on Riley and his beautiful disciples of St. Patrick."
Gen. Anaya stated in his written battle report that 35 San Patricios were killed, 85 taken prisoner (including a wounded John Riley, Captain O'Leary and Anaya); about 85 escaped with retreating Mexican forces. Some 60% of the San Patricios were killed or captured in the engagment. The survivors were reformed before the Battle of Mexico City some two weeks later and were stationed at Querétaro where the Mexican government had decamped, with some 50 members serving as a body-guard for the commander-in-chief. The battalion were caught up in the infighting and politicking of Mexico at the time, and were under the patronage of a faction that favored suing for ending of the conflict peacefully. New units were later made up of the free survivors of the battle of Churubusco and a roughly equal number of fresh deserters from the U.S. Army. Following the war, the Mexican Government insisted in a clause of the Treaty of Guadalupe Hidalgo that the remaining San Patricio prisoners held by the Americans were to be left in Mexico, and Major General William Orlando Butler issued General Orders 116 on June 1, 1848 stating that; “The prisoners confined at the Citadel, known as the San Patricio prisoners, will be immediately discharged”—Rogue’s March was played upon their release. The Saint Patrick's battalion continued to function as two infantry companies under the command of John Riley, with one unit tasked with sentry duty in Mexico City and the other was stationed in the suburbs of Guadalupe Hidalgo. The San Patricios were officially mustered out of Mexican military service in 1848; some members were alleged to have been involved in an abortive military coup, while historians have said the group was disbanded because of Mexican budget cuts.
Aftermath of Churubusco
The San Patricios captured by the U.S. Army were treated and punished as traitors for desertion in time of war. Seventy-two men were immediately charged with desertion by the Army.
Two separate courts-martial were held, one at Tacubaya on 23 August, and another at San Ángel on 26 August. At neither of these trials were the men represented by lawyers nor were transcripts made of the proceedings. This lack of formal legal advice could account for the fact that several of the men claimed that drunkenness had led them to desert (a common defense in military trials at the time that sometimes led to lighter sentences), and others described how they were forced to join the Mexican Army in some form or another. The majority of the San Patricios either offered no defense or their defenses were not recorded. Wealthy Mexicans came to the San Patricios' defence at the trails, and members of Mexico's first families visited them in prison.
One soldier who claimed he was forced to fight by the Mexicans after he was captured by them, and who subsequently refused to do so, was sentenced to death by firing squad instead of hanging, along with another who was found not to have officially joined the Mexican Army.
Most of the convicted San Patricios were sentenced to death by hanging: 30 from the Tacubaya trial and 18 from San Ángel. The rationale was that they had entered Mexican military service following the declaration of war. Execution by hanging was in violation of the contemporary Articles of War, which stipulated that the penalty for desertion and/or defecting to the enemy during a time of war was death by firing squad, regardless of the circumstances. Hanging was reserved only for spies (without uniform) and for “atrocities against civilians”, neither of which activities were among the charges brought against any members of the Saint Patricio's Battalion. Although more than 9,000 U.S. soldiers deserted the army during the Mexican–American War, only the San Patricios (who unlike almost all other deserters had also fought against the United States) were punished by hanging.
Those soldiers who had left military service before the official declaration of war on Mexico (Riley among them) were sentenced to:
|“||...receive 50 lashes on their bare backs, to be branded with the letter ‘D’ for deserter, and to wear iron yokes around their necks for the duration of the war.||”|
In all fifty Saint Patrick's battalion members were officially executed by the U.S. Army. Collectively, this was the largest mass execution in United States history—the hanging of 38 Sioux at the conclusion of the Dakota War of 1862 appears the be the largest execution by hanging at a single event. En masse executions for treason took place at three separate locations on three separate dates; sixteen were executed on 10 September 1847 at San Ángel, four were executed the following day at the village of Mixcoac on 11 September, and thirty were hanged at Chapultepec on 13 September. A sole San Patrico was murdered by American soldiers after being recognised among Mexcian prisoners of war in the aftermath of the Battle of Molino del Rey, by being thrown "into a mill flume and crushed by the wheel". At the San Ángel hangings all prisoners were executed without incident except for Patrick Dalton, who, as an American captain described, was "literally choked to death". Dalton had previously voiced concerns regarding his treatment. By order of Gen. Winfield Scott, thirty San Patricios were to be executed at Chapultepec in full view of the two armies while they fought the Battle of Chapultepec, at the precise moment that the flag of the U.S. replaced the flag of Mexico atop the citadel. This order was carried out by Col. William Harney. Harney was taunted and jeered by the condemned men. While overseeing the hangings, Harney ordered Francis O'Connor hanged even though he had had both legs amputated the previous day. When the army surgeon informed the colonel that the absent soldier had lost both his legs in battle, Harney replied:
|“||Bring the damned son of a bitch out! My order was to hang 30 and by God I'll do it!||”|
The U.S. flag appeared on the flagpole at 9.30 a.m. The Mexican flag had been taken by cadet Juan Escutia of the Niños Héroes to his death after leaping with it from Chapultepec Castle to deny the Americans the honor of capturing it. In a final act of defiance, the men about to be hanged cheered the Mexican flag, as one onlooker remarked; "Hands tied, feet tied, their voices still free". At Harney's signal, the carts holding the tied and noosed men pulled away. Harney refused to cut the bodies down, stating that "I was ordered to have them hanged, and have no orders to unhang them"; Harney was subsequently promoted to brigadier general, a post which he held while the U.S. Army occupied Mexico City. The Mexican government described the hangings as “a cruel death or horrible torments, improper in a civilized age, and [ironic] for a people who aspire to the title of illustrious and humane”, and by a writer covering the war as "a refinement of cruelty and ... fiendish". George Ballentine remarked in his account of his American military service in Mexico that "The desertion of our soldiers to the Mexican army ... were still numerous, in spite of the fearful example of the executions at Churubusco, [and] also served to inspire that party with hope".
Those who survived either made lives for themselves in Mexico or returned to their home nations such as Ireland. Some former San Patricios found work at the arsenal in Guadalajara making gun stocks. One former San Patricio, an Irishman, started a military academy teaching "the sword exercise", also in Guadalajara. Others were reportedly killed while travelling through Mexico, while others were reduced to living on handouts. A handful are on record as having made use of the land claims promised them by the Mexican government. Americans in Mexico who had been taken prisoner by Mexico or who were common desterters were known to falsely present themselves as members of the Saint Patrick's Battalion; American William W. Carpenter, who found himself in this predicament, stated that: "the reputation of the San Patricio battalion was spread from ocean to ocean, and to that, more than any thing else, do I owe my present safety".
The men have continued to be honored and revered as heroes in Mexico. The Batallón de San Patricio is memorialised on two separate days; 12 September, the generally accepted anniversary of the executions of those battalion members captured by the U.S. Army, and 17 March, Saint Patrick's Day. Numerous schools, churches and other landmarks in Mexico take their name from the battalion, including:
- Monterrey — The street in front of the Irish School is named Batallón de San Patricio ("Battalion of Saint Patrick").
- Mexico City — The street in front of the Santa María de Churubusco convent was named Mártires Irlandeses ("the Irish martyrs").
- San Patricio, Jalisco — The coastal town is named after the San Patricios
- The Wall of Honor in Mexico's Chamber of Deputies — On Thursday, October 28, 2002 the LVII Mexican Congress held a ceremony where the inscription “Defensores de la Patria 1846-1848 y Batallón de San Patricio" [Defenders of the Fatherland 1846-1848 and the San Patricio Battalion] was inscribed in gold letters.
- Banda de Gaitas del Batallon de San Patricio [The St. Patrick's Battalion Pipes & Drums] — The only Bagpipe Band in Mexico is named after the battalion. The band is based at the former Convent of Churubusco in Mexico City, which now houses the Museum of Foreign Interventions or "Museo Nacional de las Intervenciones". The band was inducted into the Irish America Hall of Fame in 2013.
- San Patricio station — Metro Zapata was renamed for one day to "San Patricio" on 17 March 2015 to commemorate Saint Patrick's day and the Saint Patrick's battalion. This was the first time a metro had been renamed in such a manner.
In the U.S. the memory of the battalion has been different. In Winfield Scott's 1852 run for president of the United States, his treatment of the San Patricios was brought up by his opponents to sway Irish American voters. The U.S. Army long denied the existence of the Saint Patrick's battalion as a cover-up and attempt to discourage other deserters. In 1915 an inquiry was initiated by U.S. congressmen William Henry Coleman and Frank L. Greene. This resulted in the U.S. Army's admitting its denial of the matter. The U.S. Congress ordered the army to turn over its records on the battalion to the National Archives. In 1999, MGM cancelled the U.S. distribution of a film dipicting the battalion, One Man's Hero.
In 1997, President Ernesto Zedillo commemorated the 150th anniversary of the execution of the San Patricios at a ceremony in Mexico City's San Jacinto Plaza. This is where the U.S. Army conducted the first 16 hangings after the men were convicted of desertion at court martial. Ireland and Mexico jointly issued commemorative postage stamps to mark the anniversary.
In 2004, at an official ceremony attended by numerous international dignitaries including directors Lance and Jason Hool, as well as several actors from the film One Man's Hero (1999), the Mexican government gave a commemorative statue to the Irish government in perpetual thanks for the bravery, honor and sacrifice of the Saint Patrick's Battalion. The statue was erected in Clifden, Connemara, Ireland, where leader John Riley was born. In honor of John Riley, on 12 September the town of Clifden flies the Mexican flag. In 2014, Sinn Féin named a cumann in Clifden in honor of John O'Reilly.
The battalion has inspired numerous responses: it is the name of a soccer team Club Deportivo Chivas USA's Supporters Association, was evoked in a Saint Patrick's Day message from Subcomandante Marcos of the Zapatista Army of National Liberation, and has been remembered as a symbol of international solidarity with Mexico.
