Admiral Pasley and Bellepheron

[realjake98]

I am very unschooled in British Naval history other than my enthusiasm for the Patrick O'Brian Aubrey-Maturin series. I am looking to learn detailed information regarding Admiral Pasley and HMS Bellephoron (1786) other than what I have gleaned on wikipedia. I am particularly interested in the type of cannons used on the ship during the Third Battle of Ushant. Can anyone point me in the direction of information (narratives, ship plans, cannon pictures, cannon plans, etc.) of this type? Any help would be appreciated
