The Second Rhode Island Infantry Regiment was an infantry regiment composed of volunteers from the state of Rhode Island that served with the Union Army in the American Civil War. They, along with the 1st Rhode Island , wore a very simple uniform. The uniform composed of a dark blue jacket like shirt, tannish grey pants, and a dark blue chasseur kepi. The 2nd Rhode Island also wore havelocks in the beginning of the war, but after finding them useless they discarded them.
The regiment was organized in June 1861 in Providence. The regiment was initially assigned to the IV Corps of the Army of Northeastern Virginia (later became the Army of the Potomac) and saw its first combat action at the First Battle of Bull Run. The IV Corps later became the VI Corps of the Army of the Shenandoah, and the 2nd Rhode Island participated in several fights in the Shenandoah Valley. The regiment was mustered out of service at Providence on July 13, 1865.
The Second was Rhode Island's fighting regiment. It fired the opening volley at First Bull Run, and was in line at the final scenes of Appomattox. It arrived at Washington, June 22, 1861, and after a few weeks encampment there, marched to the field of First Bull Run. It was then in Burnside's Brigade, of Hunter's Division. Burnside opened that fight with the First Rhode Island deployed as skirmishers, and the Second advancing in line of battle. Its casualties in that engagement aggregated 98 in killed, wounded and missing; among the killed were Colonel Slocum, Major Sullivan Ballou, and two captains. During the Peninsular campaign it served in Palmer's (3d) Brigade, Couch's (1st) Division, Fourth Corps; this division was transferred in October, 1862, to the Sixth Corps as Newton's (3d) Division. The regiment, under Colonel Rogers, distinguished itself in the hard-fought battle of the Sixth Corps at Salem Heights, May 3, 1863, in which action it lost 7 killed, 68 wounded, and 6 missing. At the Wilderness, it lost 12 killed, 66 wounded, and 5 missing; and at Spotsylvania, 15 killed, 32 wounded, and 6 missing. In the final battle of the Sixth Corps—at Sailor's Creek, April 6, 1865—the regiment displayed remarkable fighting qualities, engaging the enemy in an action so close that men were bayoneted, and clubbed muskets were freely used. The original regiment was mustered out June 17, 1864, the recruits and reenlisted men left in the field were organized into a battalion of three companies, to which five new ones were subsequently added in the fall and winter of 1864-5.
