CHARLESTOWN — Under a clear blue sky at the base of the Bunker Hill Monument Tuesday, Secretary of the Commonwealth William F. Galvin joined National Park Service officials to announce additions to the state’s commemoration of the ongoing 250th anniversary of the American Revolution.
Speaking from the grassy hill where colonial forces clashed with the British on June 17, 1775, Galvin said the Commonwealth Museum’s exhibition on the Revolution will not only be extended through July 9 — a month longer than originally planned — but also expanded to focus more directly on the pivotal early battle that took place in Charlestown.
“I don’t think the significance of this battle could be underestimated,” Galvin said. “The British wanted to contain what they characterized as a ‘rebellion’ to just Massachusetts. Many of the other colonies were still ambivalent.”
Although the regulars took the hill that day and burned most of Charlestown down, the Patriots inflicted over 1,000 casualties on the British, including more than 200 killed. The British suffered more than twice the American losses, proving to both king and colonies the fight for independence would be long and bloody, but winnable for the Americans.
“It unified the colonies in the belief that they had to take a stand to be independent, culminating just a year later on July 4, 1776, with the Declaration of Independence,” Galvin said. “So in a very real way, the blood that was spilled here set the scene for the founding of the United States.”
The additions to the “Upon Such Ground” exhibit, which opened in March at the Commonwealth Museum, 220 Morrissey Blvd., in Dorchester, will include original documents relating to the Battle of Bunker Hill, such as pay records for veterans, an 1823 petition to erect the monument that now towers above the site, and a list of survivors who returned for the battle’s 50th anniversary in 1825.
The exhibit’s title comes from a June 18, 1775, letter, a replica of which will also be on display, in which Abigail Adams who watched the battle from a nearby hill, described Bunker Hill as a “decisive day” in the course of the revolution in a message to her husband, John Adams.
In addition to the extended exhibit, Galvin announced the return of the Commonwealth Museum’s Fourth of July display of Massachusetts’ original copy of the Declaration of Independence, signed by John Hancock.
That same day, the crypt at the United First Parish Church in Quincy — final resting place of Presidents John Adams and John Quincy Adams and their wives — will also be open to the public. Offered in partnership with the National Park Service and funded by the Massachusetts Historical Commission, the special opening marks the 199th anniversary of John Adams’s death, exactly 50 years after he signed the Declaration of Independence.
Simeon Monteleone, superintendent of the National Parks of Boston, said the Park Service is prepared for increased visitation to the Bunker Hill Monument leading up to and during commemorative events on the June 17 anniversary, and emphasized its enduring role as a space for public memory.
“This monument continues to serve as a vital commemorative space, rallying point, and inspiration to veterans, community members, and visitors alike,” Monteleone said.
While the Park Service has faced staffing losses, a seasonal hiring freeze, and internal uncertainty under new federal directives, Monteleone said recent budget cuts have not disrupted core plans for the 250th anniversary. She added the agency remains committed to preserving access and programming throughout the commemorative year.
Asked why no full battle reenactment would take place in Charlestown itself, officials cited logistical and environmental constraints.
“This is an urban environment,” Galvin said. “The hills have been filled with houses now. I don’t think it could be a faithful reenactment.” He added that reenactments planned elsewhere — including in Gloucester — could better replicate the topography and scale of the original battle.
The 250th anniversary reenactment of the Battle of Bunker Hill will take place June 21–22 at Stage Fort Park in Gloucester. The event will feature tactical demonstrations, historical vignettes, and living history encampments. It’s being organized by the Massachusetts Society of the Sons of the American Revolution in partnership with the City of Gloucester and several regional reenactment groups.
As Massachusetts marks the Revolution it helped ignite, Galvin suggested the anniversary carries added weight in light of recent federal actions that have rattled institutions and residents across the state.
“I don’t think it’s political to say that democracy is under threat,” he said. “If these commemorations provide some additional inspiration now and in the future, it’s the importance of recognizing that it’s our turn — as it was theirs back then — to protect and preserve democracy.”
