Now, this man was a real historical figure and a character in just about every sense of the word, and I wanted to know more about him. So I go to Wikipedia to look him up, and what do I find?
"His career inspired a number of writers of nautical fiction. The first was Captain Marryat who had served under him as a midshipman. In the 20th century, the fictional careers of Horatio Hornblower in the novels by C. S. Forester and of Jack Aubrey in the Aubrey–Maturin series of novels by Patrick O'Brian were in part modelled on his exploits."
My italics. Jess, Star, I think we have to play with this somehow. Since the Cochrane in Sharpeverse is clearly fictionalised anyway, I think we can have him and Horatio exist in the same universe. What do you think?
