British cannon captured from HMS Diana

One of Groton’s Revolutionary War treasures is a British cannon captured from HMS Diana at the Battle of Chelsea Creek in 1775. Within days, the cannon—along with three others– was turned against the British forces at the Battle of Bunker Hill by a Colonial militia led by Groton’s Captain Asa Lawrence. The cannon somehow ended up in Groton where it was mostly forgotten until the late Earl Carter carefully restored it and rebuilt its carriage in 2016.
