I want to know the answer to the following question:
What annual festival, celebrated on New Haven Green, memorializes the New Haven's passage into the Revolutionary War?
All the background I'm provided with is that "New Haven's Saint Patrick's Day parade, which began in 1842, is New England's oldest St. Patty's Day parade and draws the largest crowds of any one-day spectator event in Connecticut.". Is that enough to answer the question?
Answer: no
