Motivations

The great majority of those men who formed Saint Patrick's Battalion were recent immigrants who had arrived at northeastern U.S. ports. They were part of the

The U.S. Army often recruited the Irish and other immigrants into military service shortly or sometimes immediately after arrival in 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

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. Irish immigrants had been faced with animosity both as a result of their

based on racist pseudo-science and treated as inferior to American nativists. 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; he said, "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 esertion" and described 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

(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 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 companies serving as an example to the supporting battalions.

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 either offered no defense or their defenses were not recorded. Wealthy Mexicans came to the ' defence at the trials, and members of Mexico's first families visited them in prison.


Sentences

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 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

Americans in Mexico who had been taken prisoner by Mexico or who were common deserters were known to falsely present themselves as members of the Saint Patrick's Battalion; American William W.
