"One Man's Hero" is a beautiful film. Beneath any flaws in style and editing, discussions of touchy subject matter, etc. etc., it presents the incredible true story of a group of Irish immigrants who deserted the US army to fight with Mexico during the Mexican War to become the San Patricios. For an $18 million film and fairly unknown director, it stands the test well and emerges an educational and compelling piece of moviemaking.

Truth be told, there's nothing spectacular about the battle scenes or any groundbreaking aspects, but the collective strength of the cast and the solid script pay homage to these men. The film boasts several brilliant "moments", a sub-plot romance, wonderful performances from supporting cast, a thought provoking subject from the archives of history, and the drama and charismatic profundity of a lost cause and ultimate tragedy. Kudos to great score and utilizing the terrain to the benefit of the film.

Though it's not a blazing Oscar candidate, this is a wonderful, sad, and highly personal film about human beings trying to make the best of an unusual and dangerous situation. It has a layered cultural atmosphere that is refreshing and enlightening, and no doubt you'll end the film with a new appreciation of history and belief in good film.

"One Man's Hero" is set in the 1840's , Mexico was embroiled in turmoil . Renegades and revolutionaries ruled the mountains and the central government was trying to regain control . The neighboring United States saw the opportunity to invade . Across the Atlantic Ocean a different battle raged , as Ireland lost half its population to the potato famine . Desperate and broken two million Irishmen sailed across to the United States . Enticed by the promise of citizenship , scores of young Catholic Irishmen joined the predominantly US Army. For most , it was their only choice . The Saint Patrick's Battalion (Spanish: Batallón de San Patricio, later reorganized as the Foreign Legion of Patricios), formed and led by John Riley, was a unit of 175 to several hundred (accounts vary) immigrants and expatriates of European descent who fought as part of the Mexican Army against the United States in the Mexican-American War of 1846-48. It is set in 1846 , the plot centers around John Riley (Tom Berenger) , an Irish immigrant soldier recruited in the American army during the Mexican-American War , being a sergeant in command of a battalion who are usually despised by the soldiers remaining . One day , John Riley and other Irishmen deserted to Mexico after in the U.S. Army during the Mexican-American War. As the motley bunch flee to Mexico , there they are assaulted and imprisoned by a Mexican guerrilla led by deserters (Joaquin De Almeida , Daniela Romo) opposite the Mexico government . Later on , Riley and his men choose to be soldiers for the Mexican Army , waging war the US invader . Riley then is commissioned as a Captain in the Mexican Army and fights with soldiers on both sides of the border.

It tells the little-known story of the "St. Patrick's Battalion" or "San Patricios," a group of mostly Irish, and other immigrants of the Catholic religion, who are mistreated , humiliated by US soldiers and encountering religious and ethnic prejudice . The script revolves around the personal story of John Riley, an Irishman who had been a Sergeant in the American Army . Here Tom Berenguer gives a good acting as the Irish sergeant who faces off anti-immigrant and anti-Catholic bigotry from his fellow servicemen and defects to the Mexican army , subsequently commanding an Irish battalion, as he leads his men in battle. He is well accompanied by a good cast, such as : Joaquin De Almeida as a rebel officer , Daniela Romo as a stubborn Guerrilla woman who falls for Riley , Mark Moses as an US upright Colonel , Stephen Toblowsky as a nasty officer , James Gammon as General Zachary Taylor , Patrick Bergin as General Scott , and a cameo by Prince Alberto de Monaco . It packs a colorful and evocative cinematography by Peter Wooley . And a rousing and thrilling musical score by Ernest Troost , shot on location in Durango , Puebla , Morelos, Mexico . Lavishly financed by Spanish/US/Mexican producers as Julio Fernandez , Jaime Comas Gil , Conrad and Lance Hool . The motion picture was well written , produced and directed by Lance Hool.

It is well based on facts , about Saint Patrick's Batalion , being composed primarily of Catholic Irish immigrants, the battalion also included Germans, Canadians, English, French, Italians, Poles, Scots, Spaniards, Swiss, and Mexicans, many of whom were also members of the Catholic Church. 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 Patricios 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".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 entice immigrants in the U.S. Army to switch sides and offered incentives to foreigners who would enlist in its army including granting them citizenship, paying higher wages than the U.S. Army, and generous land grants. U.S. Army regiments from which members are known to have deserted include: 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.The San Patricios are honored in both Mexico and Ireland.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 trials, and members of Mexico's first families visited them in prison . There had strong sentences against the Irish soldiers . 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 Patrick'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, 50 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 to 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; 16 were executed on 10 September 1847 at San Ángel, four were executed the following day at the village of Mixcoac on 11 September, and 30 were hanged at Chapultepec.

"One Man's Hero" tells of the Saint Patty's Battalion of dissident Irish soldiers who fought for Mexico during the American-Mexican war of 1846-1848 and their leader, John Reilly (Berenger). This very mediocre film tries to do too much with a story which is fundamentally not very interesting as war stories go while spicing it up with a fictional and lame romance. Generally a poor production, "OMH" gives us little reason to care about any of the characters, features a typically shallow performance by Berenger, and wanders off into an esoteric bit of history which is of little interest to most. This film is to Irish-Americans as "Glory" was to African-Americans but fails where "Glory" succeeded.
