I want to know the answer to the following question:
When did John Hawkins and Francis Drake attack Spanish and Portuguese slave ships?
All the background I'm provided with is that "This effort was rebuffed and later, as the Anglo-Spanish Wars intensified, Elizabeth I gave her blessing to further privateering raids against Spanish ports in the Americas and shipping that was returning across the Atlantic, laden with treasure from the New World.". Is that enough to answer the question?
Answer: no
