I am currently working through the New York unit casualties at Gettysburg to draw together all those of Irish-birth or Irish ethnicity who lost their lives as a result of that engagement. Four men of the 65th New York Infantry (1st United States Chausseurs) died as a result of the fighting that July– almost certainly three were of Irish birth. The story of one of them, Westmeath’s John Clark, has been told on the site previously (see here). Another was John O’Brien. A few months before his death, he wrote his mother a letter– it would seem following the Battle of Fredericksburg– which described a near fatal incident during an artillery bombardment. John was once again subjected to such a bombardment at Culp’s Hill, Gettysburg on 3rd July 1863, with less fortunate results. (1)
John’s parents John and Margaret O’Brien had been married in Ireland on 26 June 1840, by a Reverend Father Delaney. They had afterwards settled in the United States, but John Senior had passed away in Paterson, New Jersey on 21st September 1852. Both Margaret and young John had to dedicate themselves to working for their own support. While her son contributed his wages towards the family rent, Margaret provided the majority of the other necessaries through her work as a servant, one of the countless “Irish Bridgets” in domestic service. During the 1860s their home was in Manhattan, at 243 Mulberry Street. (2)
Today’s 243 Mulberry Street in New York. Margaret O’Brien lived at this address in the 1860s.
Although not an Irish regiment, the 65th New York Infantry had many Irishmen in the ranks. Perhaps the most notable was Andrew Byrne, who would eventually return to Ireland and write his memoirs, now published (see here). John O’Brien was another. He had enlisted on 21st August 1861 at the age of 19, going on to serve as a private in Company H. The regiment had seen heavy fighting on the Peninsula during the summer of 1862, but had avoided the worst of the fighting at Antietam and Fredericksburg, though they were more closely involved in the action around Fredericksburg during the Chancellorsville Campaign. In John’s file is the letter he wrote to his mother, which although problematic, appears to have been composed after the December 1862 Battle of Fredericksburg (though there are slight errors in dates, location names and casualties, John’s description of the fighting would appear to match the regiment’s experience there). Despite the fact that the 65th was not heavily engaged, John’s correspondence provides an extremely interesting insight into cooperation with Rebels on picket duty, the strains of experiencing a bombardment, and the shock that the heavy defeat at Fredericksburg caused throughout the Army of the Potomac.

Of course, the reason this letter survives is because John O’Brien died as a result of his service. During the bombardment which the 65th New York endured at Culp’s Hill on 3rd July (the same bombardment which so horribly killed John Clark), John’s luck at dodging shells ran out. His officer later recorded that he was “killed at the Battle of Gettysburg Pa on the 3rd day of July 1863 by a solid shot passing through his body.” (5)(1) John O’Brien Widow’s Pension File; (2) Ibid.; (3) 65th New York Roster, John O’Brien Widow’s Pension File; (4) John O’Brien Widow’s Pension File; (5) Ibid.
