Seth Warner was born in 1743 in what is now Roxbury, Connecticut, and grew up in neighboring Woodbury. As a young man he moved to the New Hampshire Grants, the disputed territory that later became Vermont. There he joined the Green Mountain Boys, who resisted New York land claims and defended settlers holding grants issued by New Hampshire. Warner's local leadership prepared him for a larger military role when the American Revolution began.

In 1775 Warner participated in the capture of Crown Point and served during the campaign in Canada. He later commanded troops during the difficult retreat from Quebec. Congress authorized an additional Continental regiment under his leadership, commonly called Warner's Additional Regiment. At Hubbardton in July 1777, his men fought a rear-guard action that helped protect the withdrawing American army. The following month they played an important role in the American victory at Bennington.

Years of campaigning damaged Warner's health. He returned to Roxbury after the war and died there on December 26, 1784, only forty-one years old. He was initially buried in the local burying ground associated with this site. Like many Revolutionary officers, Warner was remembered first through family and community tradition, while the young nation gradually developed a broader public culture of monuments and battlefield commemoration.

In 1859, amid renewed interest in the Revolutionary generation, Warner's remains were moved to a more prominent location on the Roxbury green and placed beneath a large granite monument. That reinterment means the original burial place and the later memorial perform different historical roles. The older ground marks the community landscape in which Warner was first laid to rest; the monument reflects a nineteenth-century effort to elevate him as a public hero of Connecticut and Vermont.

The burial site therefore connects several layers of memory: Warner's return home, his original interment, and the later relocation of his remains. His career links the local disputes of the Green Mountain Boys to major campaigns of the Revolution, while the treatment of his grave shows how later generations reshaped commemoration. Visitors should distinguish the historic burial ground from the present monument, but both places help explain how Warner's reputation survived long after the war. Warner's reputation developed differently in the two states that claimed him. Vermont remembered a foundational military leader connected to the Green Mountain Boys, while Connecticut emphasized the Roxbury-born veteran who returned home. Commemorations in both places simplified a career marked by frontier politics, hard campaigning, illness, and uncertain rewards. The original grave and later monument allow visitors to examine that process: a private burial became a public symbol as communities sought tangible links to the Revolutionary generation.
