Hugh Donnelly enlisted in the 38th New York Volunteer Infantry as a private in Company E on May 7, 1861. The 38th New York suffered some 138 casualties at First Manassas and like much of the Union Army that fought at that battle returned to the defenses of Washington until the spring of the following year and the beginning of the Peninsula Campaign. The regiment fought during the Siege of Yorktown, at Williamsburg and a Seven Pines during April and May and at Williamsburg Donnelly was wounded on May 5. The regiment fought during the Seven Days before Richmond, including Oak Grove, White Oak Swamp, Glendale and Malvern Hill. On August 26, 1862 Donnelly was discharged for promotion and was commissioned as a captain the following day. He was mustered into the 37th Massachusetts Infantry on September 4, as the captain of Company I. The 37th Mass saw action at essentially all of the major battles in the east from the end of 1862 through the end of the war. These included Fredericksburg, the Chancellorsville Campaign, Gettysburg, the Mine Run Campaign, the Wilderness, Spotsylvania, Cold Harbor, the Siege of Petersburg, Winchester and the Appomattox Campaign. At Cold Harbor the colonel of the 37th was given command of the brigade and Donnelly was made the acting colonel, commanding the regiment. During that battle on June 5, 1864 he was wounded in the head and discharged for disability on January 31, 1865.
