Rediscovering the Bunker Hill Fortifications
Using ground-penetrating radar, archaeologists located a ditch and earthworks built hours before the June 17, 1775 Battle of Bunker Hill. The dig, led by Boston archaeologist Joe Bagley, removed soil in 4-inch layers, screened it, and uncovered a fort layout that matches Henry Pelham’s 1775 map.
Battle Context and Significance
The June 17, 1775 clash on Breed’s Hill, often called the Battle of Bunker Hill, was one of the Revolution’s first major engagements. British forces suffered over 1,000 casualties while roughly 150 colonial fighters died. The battle’s defensive stand boosted colonial morale and is commemorated by a 221-foot white obelisk on the hill.
Findings and Data
Excavators recovered eight marble-sized musket balls from both sides, English and French gun flints, a musket fragment, tea cups, tobacco pipes, sleeve buttons, and a wig curler. The ditch is about 3 ft deep and over 6 ft wide; the parapet wall rises roughly 6 ft and stretches about 150 ft on each side. No human bones have been found.
Official Statements & Response
Boston officials said the excavation, timed with a Wednesday remembrance ceremony at the Bunker Hill Monument, “provides a tangible link between the historic maps and the physical landscape of 1775.” The city called the trench “the reason why all of this is here” and noted that a forensic archaeologist remains on site to examine any bone fragments.
Public Engagement
The dig drew tourists, including visitors from Colorado, who called the experience “a wonderful surprise” and “immersive.” Volunteers and local residents worked through the night to expose the fort’s dimensions. The Wednesday ceremony will feature a wreath-laying, a moment of silence, and a musket-firing demonstration for attendees.
