Uncover the Story of the Battle of Chelsea Creek — the First Naval Engagement of the American Revolution
It’s the spring of 1775 in Boston, and tensions are rising. The Siege of Boston has been going on for months. The British have taken control of the city, but their survival lies in the islands on the Harbor Islands and seacoast, where they have livestock and fodder.
Trapping the colonists inside the city, the future of the American colonies hangs in the balance. But the colonists aren’t about to let them get these supplies without a fight. Along the shores of Chelsea Creek, a small but crucial battle is about to take place—one that’s often forgotten yet shaped the course of the American Revolution.
