I want to know the answer to the following question:
When did Prince Charles write to Burke?
All the background I'm provided with is that "Burke believed the Government was not taking the uprising seriously enough, a view reinforced by a letter he had received from the Prince Charles of France (S.A.R. le comte d'Artois), dated 23 October, requesting that he intercede on behalf of the royalists to the Government.". Is that enough to answer the question?
Answer: yes
