1st Rhode Island Infantry Regiment

1st Rhode Island Infantry Regiment was an infantry regiment raised in Rhode Island for service in the American Civil War. Mustered into Federal service in 1861, the regiment served in the Army of the Potomac and participated in several major campaigns in the Eastern Theater. Its companies drew men from Providence, Newport, Woonsocket and other communities, and the unit's service is documented in state records, contemporary newspapers, and soldiers' letters.

Formation and Organization

The regiment was formed under state authority following President Abraham Lincoln's call for volunteers after the fall of Fort Sumter and the outbreak of the Civil War. Recruitment was organized by Rhode Island's governor, William Sprague, and the adjutant general's office in Providence. Companies were mustered at state armories and enclosed drill fields, enlisting men from urban centers like Newport County and industrial towns including Pawtucket and Cranston. Officers received commissions under state militia statutes and federal mustering orders issued by the War Department. The regiment's early organization followed the standard American Civil War regimental structure with ten companies labeled A through K, appointed noncommissioned officers drawn from veteran militia units, and a regimental staff including a colonel, lieutenant colonel, major, adjutant, quartermaster, and surgeon.

Service History

After muster, the regiment was assigned to the defenses of Washington, D.C. and attached to brigades within the I Corps and later brigades of the II Corps of the Army of the Potomac. It took part in the Northern Virginia campaigns under commanders such as Major General Irvin McDowell and later served in operations directed by Major General George B. McClellan and Major General Ambrose Burnside. During the Maryland Campaign the regiment moved with the army across the Potomac River into Maryland, and later participated in the winter encampments around Falmouth and the subsequent movements toward Fredericksburg. The unit’s service included marches along the Rappahannock River and sustained duty in siege operations during the prolonged campaigns around Petersburg. Throughout its term, the regiment exchanged prisoners, received recruits from Rhode Island rendezvous points, and underwent reorganization consistent with army regulations issued by the War Department.

Commanders and Notable Personnel

Commanders who led the regiment included officers commissioned from state militia backgrounds with ties to Rhode Island political and civic life. The colonelcy was held by men prominent in state affairs and veterans of earlier militia service. Company officers included captains and lieutenants drawn from towns such as Bristol County, Kent County, and Washington County. Notable noncommissioned personnel included sergeants and corporals who later appeared in veterans’ organizations such as the Grand Army of the Republic. Several members subsequently held municipal and state offices in Providence and other Rhode Island localities, and a number of veterans authored memoirs or gave depositions used in postwar pension files administered by the Pension Bureau.

Engagements and Battles

The regiment saw action in multiple named engagements of the Eastern Theater. Early in its service the unit was present during the First Battle of Bull Run operations around the capital defenses. It later participated in the Second Battle of Bull Run campaign and was engaged during the Maryland Campaign at the Battle of Antietam. Elements of the regiment fought during the Battle of Fredericksburg crossings and assaults on fortified positions. In the later war the regiment took part in siege operations associated with the Siege of Petersburg and related actions during the Overland Campaign under the overall direction of Lieutenant General Ulysses S. Grant. The regiment’s companies were engaged in skirmishes, reconnaissance-in-force missions, and entrenched siege warfare that typified the transition from maneuver to attrition in the campaigns of 1863.

Casualties and Losses

The regiment suffered killed and wounded in major battles, with additional losses from disease, accident, and detachments taken prisoner during engagements and raids. Like many Union regiments, non-battle attrition—principally dysentery, typhoid fever, and smallpox—accounted for a significant share of the regiment’s losses reported in muster-out rolls and hospital returns. Surviving muster rolls and regimental returns deposited in state archives list names of men killed in action at specific fights such as Antietam and Fredericksburg, as well as those who died at field hospitals like Armory Square Hospital in Washington, D.C.. Casualty figures were reported to the Adjutant General of Rhode Island and compiled in postwar summaries used for veteran pensions.

Legacy and Commemoration

Postwar commemoration of the regiment took place through participation in veterans' reunions, monument dedications at battlefields, and entries in Rhode Island regimental histories and rosters. Veterans joined fraternal organizations such as the Grand Army of the Republic and attended ceremonies at national sites like the Antietam National Battlefield and Fredericksburg National Military Park. Local memorials and plaques in Providence and other Rhode Island towns honor companies and individual soldiers. The regiment’s lineage and records are preserved in collections at the Rhode Island Historical Society and the National Archives, which hold muster rolls, correspondence, and photographic collections documenting its wartime experience.
