American Revolution in Massachusetts

Due in large part to its close proximity to Bunker Hill, Washington ordered Ploughed Hill in Charlestown (now Mount Benedict in Somerville) to be fortified. About 3400 men lead by General John Sullivan fortified the hill on the night of August 26.

On the following day, the fortifications were subject to a near-constant barrage of canon fire from British forces on Bunker Hill and two floating batteries in the Mystic River that lasted for most of the day. Unable to fully respond to the barrage due to low supplies of ammunition, the Colonists fired only one shot with cannon and successfully sunk one floating battery while the other ceased firing.

Casualties
Colonists: 4 killed, 2 “by their own folly” according to Washington
British: unknown

Result
American victory

Aftermath
The British regularly bombarded the fortifications on Ploughed Hill until September 10; the hill supposedly received more fire than any of the other forts in the area with more than three hundred shells falling in the first few days. The Colonists were able to maintain a strategic advantage by holding the hill for the duration of the siege.
