The 6th Regiment Massachusetts Volunteer Militia was a peacetime infantry regiment that was activated for federal service in the Union army for three separate terms during the American Civil War (1861-1865). The regiment gained notoriety as the first unit in the Union Army to suffer fatal casualties in action during the Civil War in the Baltimore Riot and the first militia unit to arrive in Washington D.C., in response to President Abraham Lincoln's initial call for 75,000 troops. Private Luther C. Ladd of the 6th Massachusetts is often referred to as the first Union soldier killed in action during the war.
In the years immediately preceding the war and during its first enlistment, the regiment consisted primarily of companies from Middlesex County. During its first term of service, four out of ten companies of the regiment were from Lowell, Massachusetts. Colonel Edward F. Jones commanded the regiment during its first term. He later commanded the 26th Massachusetts and was awarded the honorary grade of brevet brigadier general. During its second and third terms of service, the unit was commanded by Colonel Albert S. Follansbee.
The regiment first enlisted for a "90-day" term of service which lasted from April 16 to August 2, 1861. Following their engagement in the Baltimore Riot, the 6th Massachusetts proceeded to Washington and then returned to Baltimore to guard locations within the city as well as the Baltimore and Ohio Railroad station at Elkridge, Maryland. Their second term of service lasted nine months from August 1862 to June 1863. During this time the 6th Massachusetts was attached to the VII Corps and participated in several expeditions and actions in the vicinity of Suffolk, Virginia, most notably the siege of Suffolk and the Battle of Carrsville in April and May 1863. Private Joseph S.G. Sweatt's bravery at Carrsville earned him the Medal of Honor. The 6th Massachusetts served a third term in response to the call for troops to defend fortifications around Washington. During this term, which lasted 100 days from July to October 1864, the 6th Massachusetts garrisoned Fort C. F. Smith in Arlington, Virginia and guarded Confederate prisoners of war at Fort Delaware near the mouth of the Delaware River.
Earlier units
The 6th Massachusetts regiment that served during the Civil War was formed in 1855 during the reorganization of the Massachusetts militia. Other units dating back to the 18th century were given the designation 6th Regiment Massachusetts Militia. They were formed and disbanded at various times and although they shared the same numerical designation, there was no continuous unit known as the 6th Massachusetts. One of the units designated as the 6th Massachusetts was a regiment that served during King George's War in the siege of Louisbourg in 1745. During the Revolutionary War, the 6th Massachusetts Regiment was engaged in the Battle of Bunker Hill, the Battle of Harlem Heights, the Battle of Trenton and the Battle of Saratoga.

Preparations
Shortly after South Carolina issued its Declaration of Secession, Massachusetts Governor John A. Andrew anticipated imminent civil war and issued an order on January 16, 1861, to the ten existing Massachusetts units of peacetime militia to immediately reorganize and prepare for active service. Colonel Edward F. Jones was the first militia commander to respond to the Governor's order. His letter indicating the regiment's readiness, dated January 21, was brought to Boston and read in the Massachusetts Senate by then state Senator Benjamin F. Butler.
On April 15, 1861, three days after Confederate forces fired on Fort Sumter, President Lincoln issued a call for 75,000 volunteers to serve in putting down the insurrection. The call was relayed by Governor Andrew to the existing regiments of Massachusetts militia the same day. Eight companies of the original 6th Massachusetts (one from Acton, one from Groton, two from Lawrence, and four from Lowell) gathered in Lowell on April 16 and proceeded to Boston. That night, the men of the 6th Massachusetts barracked in Faneuil and Boylston Halls. The next morning, April 17, three companies previously belonging to other Massachusetts militia units (one from Boston, one from Stoneham, and another from Worcester) were added to the 6th Massachusetts to form a regiment of 11 companies total. Thus composed entirely of existing volunteer militia companies, the 6th Massachusetts was made up of volunteer soldiers. The regiment proceed that day to the State House, where Governor Andrew presented regimental colors to Colonel Jones. The 6th Massachusetts departed Boston for Washington via railroad at 7 p.m. on April 17.
