One of the most strategic and decisive victories of the Revolutionary War, the bold action of Patriots (including men of Yarmouth) at Dorchester Heights fooled the British navy into ending its siege of Boston, fleeing on March 17, 1776. Come see and hear the stories in an interactive portrayal of “Yarmouth Patriots” who were part of that historic night.
