Colonel Patrick Kelly commanded the Irish Brigade at Gettysburg. Colonel Kelly was born in County Galway, Ireland and emigrated to the United States before the Civil War. He became captain of Company E of the 69th New York State Militia at the start of the war, fighting at Bull Run. Kelly became lieutenant colonel of the the 88th New York Infantry Regiment when it was formed in September of 1861. He was in command of the regiment at Antietam as senior officer. Kelly became colonel in October of 1862. He led the regiment in the charge on Marye’s Heights at Fredericksburg, where it advanced closer to the stone wall than any other unit.
Kelly commanded the Irish Brigade after Fredericksburg while Brigadier General Meagher recovered from injuries. He took over again after Chancellorsville when Meagher resigned. Kelly resumed regimental command when Colonel Richard Byrnes returned to the brigade in May of 1864. But Kelly once more took over brigade command when Byrnes was killed two weeks later at Cold Harbor. Kelly died only two weeks after that, leading an attack by the brigade at Petersburg.
