Heavy Impact: British Cannonball Fired in Lexington on April 19, 1775
April 04, 2023
Its surface is pitted and its usefulness long gone, but this six-pound iron ball tells an intriguing story of the first military battle of the Revolutionary War and its effect on the town of Lexington, Massachusetts.
According to an accompanying plaque, this cannonball was “fired in 1775 by ‘British regulars’ under command of Captain Earl Perry [sic] during their retreat from Lexington Green.” On April 19th of that year, the first battle of the Revolutionary War was fought in Lexington, now the home of the Scottish Rite Masonic Museum & Library.
Tensions had been high between Massachusetts citizens and the British government – represented by its royal troops - since the soldiers had landed in Boston in 1769. This friction had already led to such events as the 1769 Lexington Spinning Protest, the 1770 Boston Massacre, and the 1773 Lexington Tea Burning and Boston Tea Party.
These tensions and other events led to an armed conflict between Lexington’s Training Band and British troops on April 19, 1775. A contingent of British soldiers headquartered in Boston were deployed on an overnight mission to retrieve stolen cannon and ammunition hidden in Concord. After a short engagement at dawn in which eight Lexington men were killed and ten wounded, the British troops continued to Concord where they found themselves in a pitched battle at the Old North Bridge with militia members from Concord and surrounding towns. Eventually, the order to retreat was given and the British soldiers began a long and harrowing march back to Boston.
Local militias reengaged British troops many times along the route back – now called “Battle Road” – but the fighting took a different tone as the troops marched back through Lexington. By this time, relief troops from Boston had positioned two six-pound cannon at a rise east of the town center to provide covering fire for the soldiers on foot.
This bombardment led to cannonballs smashing through both the Lexington meetinghouse on the Green and one of the houses west of the Green on Harrington Road. According to SRMML’s records, the museum's cannonball was excavated in 1956 - 181 years after the battle - by local Mason Harold L. Worth (1909-1993) from the “south side of Merriam Hill.” This ball was found within the range of the British cannon that day. The location of the find supports the message on the cannonball’s plaque – that it was fired by British soldiers.
To confirm this information, SRMML staff measured the cannonball. The British were using six-pound field pieces that day and a six-pound cannonball is usually around 3.58 inches in diameter. As you can see on the right, this cannonball is 3.52 inches, which is within the expected range for historical examples. Using historical accounts, maps, and munitions specifications, we feel confident that this cannonball was fired during the conflict between Massachusetts citizens and British soldiers.
The cannon and troops are long gone, but the town of Lexington is still deeply tied to the events of April 19, 1775. Its landscape and people were profoundly marked by the attack. Evidence of that impact remains in the military detritus left behind. It is also on display in the reenactments and commemorations of the battle held annually in Lexington.
