I want to know the answer to the following question:
Who wrote to Burgoyne on February 8th?
All the background I'm provided with is that "The Lord Cowley wrote on 8 February to Burgoyne "Your visit to Paris has produced a visible change in the Emperor's views, and he is making every preparation for a land expedition in case the last attempt at negotiation should break down.":411". Is that enough to answer the question?
Answer: yes
