2nd Maine Heavy Artillery Regiment was a Union American Civil War heavy artillery regiment mustered in Maine in 1864 and assigned to the defenses of Washington, D.C., later participating in operations around Petersburg, Virginia and the Appomattox Campaign. Raised during the administration of Abraham Lincoln and the governorship of Israel Washburn Jr., the regiment served under corps and departmental commands including the Army of the Potomac and the Department of Washington. Its service intersected with major Civil War figures such as Ulysses S. Grant, George G. Meade, Winfield Scott Hancock, and regional commanders in Maine and Virginia.

Formation and Organization

The regiment was organized at Portland, Maine and surrounding recruitment centers during 1864 under authorization from the Maine Adjutant General and state authorities associated with Governor Israel Washburn Jr., drawing volunteers from counties including Cumberland County, Maine, Sagadahoc County, Maine, and York County, Maine. Officers received commissions under the laws of Maine and were mustered into United States service at federal mustering points coordinated with the War Department in the midst of campaigns overseen by General-in-Chief Ulysses S. Grant. Men transferred from or replaced earlier units raised after the Battle of Gettysburg recruitment drives and were issued regimental designations consistent with other Maine heavy artillery units such as the 1st Maine Heavy Artillery Regiment.

Service and Campaigns

Initially posted to the defenses of Washington, D.C. alongside units of the VI Corps and the Department of Washington, the regiment manned fortifications including the ring of forts around the capital like Fort Stevens and Fort Lincoln. In 1864–1865 the regiment moved into the field for the Siege of Petersburg, participating in trench operations, siegeworks, and actions connected to the Richmond–Petersburg Campaign. Elements engaged in the Appomattox Campaign and were present during the final operations that culminated in the surrender at Appomattox Court House where commanders of the Army of Northern Virginia and Army of the Potomac negotiated terms under observers including Ulysses S. Grant and Robert E. Lee-linked staff. The regiment’s timeline overlaps operations such as the assaults at Petersburg National Battlefield and movements tied to corps commanders like Winfield Scott Hancock and divisional leaders from the Army of the Potomac structure.

Role and Equipment

As a heavy artillery formation, the regiment was trained and equipped for garrisoning permanent and field fortifications, operating siege guns and heavy ordnance supplied via the Ordnance Department and federal arsenals such as the Springfield Armory or regional depots. Small arms issued included contemporary service rifles and carbines used by Union artillerymen during the period, while artillery sections employed siege pieces and mortars comparable to batteries operating with the Army of the Potomac at Petersburg. Training emphasized fortification construction techniques derived from manuals circulating among Federal engineers tied to the United States Army Corps of Engineers and fort design principles used at Fort Monroe and other Atlantic coast defenses.

Casualties and Losses

The regiment sustained losses from combat-related actions during the Siege of Petersburg and the concluding Appomattox Campaign, as well as from diseases endemic in Civil War encampments documented in reports like those compiled by the Surgeon General. Fatalities, wounded, and disease casualties reflected patterns seen across similar heavy artillery units such as the 1st Maine Heavy Artillery Regiment and other Union regiments engaged in siege operations. Loss reports and returns were filed through departmental channels including the Department of Washington and forwarded to the War Department for inclusion in the official record of losses.

Commanders and Notable Officers

Regimental leadership included colonels and field officers commissioned under Maine authority and recognized by federal command; their service placed them alongside senior leaders of the Union war effort such as Ulysses S. Grant, George G. Meade, and corps commanders like Winfield Scott Hancock. Company officers and noncommissioned officers often came from Maine communities and later appear in veterans’ records, state adjutant general reports, and postwar organizations including the Grand Army of the Republic. Some officers went on to civic roles in Maine municipal and state government, reflecting connections to figures such as Governor Israel Washburn Jr. and Maine’s postwar political leadership.

Legacy and Commemoration

The regiment’s legacy is preserved in state archives, monumentation at sites including Petersburg National Battlefield and memorial registers maintained by the State of Maine and the Maine Historical Society. Veterans participated in reunions and in Grand Army of the Republic posts that commemorated service alongside other Union formations like the 1st Maine Heavy Artillery Regiment and infantry regiments from Maine. Contemporary scholarship and battlefield preservation efforts by organizations including the National Park Service and regional historical societies continue to document the regiment’s role within the broader narratives of the Richmond–Petersburg Campaign and the closing operations of the American Civil War.
