I want to know the answer to the following question:
In what year during the Hundred Years' War did the French assault Plymouth?
All the background I'm provided with is that "In 1512 an Act of Parliament was passed for further fortifying Plymouth, and a series of fortifications were then built, including defensive walls at the entrance to Sutton Pool (across which a chain would be extended in time of danger).". Is that enough to answer the question?
Answer: no
