Final answer:
Paul Revere was court-martialed and acquitted over the 1779 Penobscot expedition which took place in what is now known as Maine.
Step-by-step explanation:
The Penobscot expedition took place in what is present-day Maine. Paul Revere was indeed court-martialed for his role in this disastrous 1779 American naval operation during the Revolutionary War. However, after the court proceedings took place Revere was acquitted of all charges related to the mission. The fact that the expedition occurred in the Penobscot Bay area, which would later become part of the state of Maine after the separation from Massachusetts in 1820, is central to the question.
