As the Irish in the American Civil War site continues to develop it is intended that the regular articles will be interspersed with ‘Discussion and Debate’ pieces, aimed at stimulating dialogue and asking or posing specific questions about the Irish experience of the war. Certain topics will include follow-on posts, allowing for responses or differing viewpoints to be expressed. The first of these has been kindly provided by Jim Swan, author of Chicago’s Irish Legion: The 90th Illinois Volunteers in the Civil War (see book review here), who puts forward a piece entitled ‘On Stereotyping Irish Soldiers’.

Among Civil War historians, there is a strong temptation to describe Irish-Catholic soldiers who fought in American’s Civil War with broad generalizations. Such an approach fails to recognize the great diversity that characterized these soldiers. In writing The Harp and the Eagle, Susannah Ural Bruce attempts ‘to convince the reader of what I discovered through years of detailed reading and research. Dual loyalties to Ireland and America influenced the actions of Irish Catholic volunteers in the Union Army during the American Civil War.’ She also discusses other loyalties to families, church, and local Irish Catholic communities, yet fails to question whether these loyalties might better describe the motivation of some Irish Catholic soldiers. As Randall Miller observed: ‘Although the vast majority of Irish Catholic soldiers served in non-Irish regiments, most judgments about the loyalty and character of the Irish Catholic soldier come from observations of Irish regiments.’ Most Irish regiments receiving such attention served in the East. Irish Catholic soldiers were not a homogenous group of men. Instead, they exhibited different loyalties, most served in non-Irish regiments, and underwent very different experiences before and during the war. Soldiers featured in this Blog: Irish in the American Civil War illustrate the great diversity of these Irish Catholic soldiers. (1)

Many Irish soldiers no longer had immediate families in Ireland, but had cut familial ties with ‘the old country’ and established ties in the new one. Although most were proud of their Irish heritage and held a ‘soft spot’ in their hearts for ‘the old sod,’ these soldiers held citizenship loyalty only to America. Presumably this was more characteristic of those who had migrated to the western states than it was of those who were new arrivals in large eastern cities. (2)

Most Irish Catholic soldiers who had been in America for a few years had developed loyalty to the Democrat Party. The Republican Party incorporated Know-Nothings and Abolitionists who actively discriminated against Irish immigrants, especially those of the Roman Catholic faith, whereas the Democrat Party defended them. This loyalty led them to align their thinking with that of the Democrat Party. Although, some Democrats supported the war, most party leaders opposed it. In western states the so-called ‘Copperheads’ were primarily anti-war Democrats. Yet, many Irish Democrats fought for the Union and there is evidence that some, alienated by Copperhead resistance to the war, became supporters of the Republican policy toward the war. In early 1864 one soldier in the Irish 90th Illinois Volunteer Infantry wrote ‘This might have been a copperhead Regt. when it came out but I am sure its not one now.’ He added it may ‘return a republican Regt.’. A Captain of the 90th expressed his, and he believed [Sherman’s] Army’s, support for Lincoln’s reelection and their lack of sympathy with ‘Copperheads.’ Later that year Major Flynn of the 90th Illinois went back to his home area in northern Illinois and campaigned for President Lincoln’s reelection. For some Irish Catholic soldiers at least, allegiances changed during the war. (3)

Did loyalty to Ireland lead some Irish Catholic soldiers to enlist? Certainly Generals Corcoran and Meagher seemed to think it would when, as part of their recruitment efforts, they told potential enlistees that their experience fighting in American’s Civil War would prepare them to return to Ireland and fight to liberate it from England. Nonetheless, there is little evidence that this was a major factor for most. Conversely, of the estimated 145,000 Irish Catholic Civil War veterans, less than 1,000 veterans and non-veterans took part in the post-war Fenian invasions of Canada out of an estimated American membership in the Fenian Brotherhood of 300,000 in 1865. (4)

Did Irish Catholics join the Union army to preserve the United States as a refuge for Irish immigrants or in recognition and gratitude for protection provided past Irish immigrants? Both reasons are given as inducements for recruitment, however, the latter implies loyalty to the United States rather than Ireland. (5)

Location also mattered. Soldiers who fought in the western theater experienced the Civil War differently from those who fought in the East. The size of the theaters differed, with western troops marching much greater distances during most of their major campaigns than those in the East.  The war in the West was more often one of maneuver and occupation of territory following military success rather than of repeated massive assaults in what became a war of attrition in the East. Western armies spent greater efforts to maintain their long supply lines deep into Confederate territory and western soldiers not infrequently found themselves short of supplies requiring that they ‘live off the land.’ Differences between western and eastern troops in their attitude, deportment, and dress were highlighted in press descriptions of the Grand Review in Washington at the end of the war. Irish and non-Irish alike shared such differences in the experiences and demeanor of eastern and western soldiers. (6)

Press attention focused on the conduct of the war in the East, slighting coverage of the war in the West, where there were fewer large population centers and fewer major newspapers. For Irish soldiers, press attention focused on brigades or larger units, such as Brigadier General Thomas Francis Meagher’s Irish Brigade or Brigadier General Michael Corcoran’s Irish Legion in the East, shining a spotlight on their actions, and obscuring the actions and experiences of most Irish Catholic soldiers widely dispersed throughout both the eastern and western Union armies. (7)

The historical record suggests that it is misleading to characterize Irish Catholic soldiers in America’s Civil War in broad generalizations drawn from their experiences in a few units because of the many ways in which they as individuals differed, as well as the ways in which their experiences differed. Letters from these soldiers illustrate individual characteristics, but to suggest that a limited number of letters, especially from a particular group of soldiers, can be used to illustrate the characteristics of most Irish soldiers, as some have done, is unwise. As a group, Irish Catholic soldiers in America’s Civil War were too diverse to be stereotyped. We should guard against this.
