A Closer Look at the Landscape of Bunker’s Hill

Back in 2017, I shared a map of the Battle of Bunker Hill that Gen. Henry Clinton had drawn himself on the back of some sheet music (permalink).

I wrote:

One eye-catching detail is that Clinton sketched a small fortification on top of Bunker’s Hill . . . There are even lines indicating that one of the warships in the Charles River fired at that site. . . .

evidently on 17 June, Clinton perceived the provincials as having fortified themselves there

This spring Boston 1775 reader Adam Derenne sent an email shedding some light on that mystery:

I believe that Clinton misinterpreted the site — it wasn’t a partial fortification but a gravel pit operated by Charlestown resident Peter Edes.

As Mr. Derenne pointed out, Edes’s gravel pit is mentioned in Charlestown’s 1767 land survey:

Then we measurd a Gravel Pitt Enclos’d & Improv’d by Mr. Peter Edes with his land lying Bounded on the way leading over Bunker’s Hill just opposite to Temple’s Barn. We began about 8 Feet below the easterly part of his Mr. Edes’s Stone Wall, said Wall being on the Way from Temples leading over Bunker’s Hill…

This owner was probably the Peter Edes (1705–1787) whose son Benjamin became a printer of the Boston Gazette (and had a son named Peter).

Mr. Derenne also noted that the City of Boston’s G.I.S. website shows what properties Peter Edes owned in 1775, covering the odd spot in Clinton’s map. Thomas Hyde Page’s map of the battle, published in 1793, showed a blob where Clinton drew that second fortification, presumably the gravel pit.

I then went looking for a mention of this pit in accounts of the battle. Did provincials use it to shelter themselves from the Royal Navy shelling that side of Charlestown? Did British engineers incorporate it into their fortifications on Bunker’s Hill, either the quick barriers made on the evening of 19 April or the sturdy fort built over time after 17 June? But I couldn’t find any account mentioning the gravel pit. So there’s still a mystery to solve.
