The Death of Color Sergeant Peter Welsh, 28th Massachusetts Infantry

Color Sergeant Peter Welsh of the 28th Massachusetts Regiment has become one of the best known members of the Irish Brigade. The publication of his Civil War letters in 1986, under the title Irish Green and Union Blue, revealed the picture of a man devoted to the cause of Union. In the summer of 1862 he had travelled from his home in New York to Boston to settle a family dispute, only for both sides of the argument to turn on him. Despondent, he embarked on a drinking spree, spending all the money he had travelled with. He was so ashamed of his actions that he enlisted in Company K of the 28th rather than return home. (1)

Peter Welsh appears to have been a born soldier, and on St. Patrick’s Day 1863 he had his proudest moment when he was promoted to carry the regiment’s green flag. His letters are in the main written to his wife, Margaret, and many seek to allay her concerns for his safety and to justify his service in the army. When she expressed her fears that he would be even more of a target when carrying the colors, Welsh wrote a detailed explanation to counter this, telling her ‘there is no such thing as taking shure aim in the battlefield’ and that ‘those on either side of the colors…are more likely to get struck then the color bearer’. His attempts to protect his wife as much as possible from the brutal reality of warfare are heart-warming. (2)

Peter Welsh fought with the 28th Massachusetts from South Mountain to Spotsylvania. On 15th May 1864 he wrote the following letter to Margaret:

Washington May 15th/64

Margaret rushed to her husband’s side. He had been sent to Carver Hospital in Washington, where on 14th May Surgeon O.A. Judson reported his injury as a ‘gunshot wound of left forearm, by a conoidal ball, producing compound comminuted fracture of inferior third of left ulna. On 17th May, two days after Welsh had written to his wife, Acting Assistant Surgeon J.S. Wentz operated on his injury, removing broken pieces of his ulna and the bullet. After the procedure he was apparently doing well, but his health began to deteriorate on 20th May. It transpired that he was suffering from pyaemia, a type of blood poisoning. Color Sergeant Peter Welsh died on 28th May 1864. Margaret, who must have been distraught, sent a telegram to her uncle in New York; it read simply ‘HE IS DEAD AND WILL BE IN NYORK IN MORNING’. Peter Welsh is buried in Calvary Cemetery, Woodside, Queens, New York. His war letters remain, providing us with some of the most insightful and poignant information on the Irish experience of the American Civil War. (3)

    My grandparents are buried very close to Peter Welsh in Calvary Cemetery. It was because of his tombstone that I began reading and studying the civil war many ago. I always place a new flag at his gravesite whenever I go to this cemetery. This is the first time I’ve seen this article on Peter Welsh and for me to get to know a little more about this man, a
    soldier and husband after years of wondering what he might of been like back in 1863.

      Hi John,

      Many thanks for the comment. I would love to visit his grave- have you read his letters? They are well worth delving into, one of the major contributions to our knowledge of Irish thoughts and motivation during the Civil War.

      Kind Regards,
