While on the subject of the Napoleonic wars in the early 70s this series by the BBC was big news for my 12 year old self. See them here. I had a souvenir guide - a colour magazine that was brought out to accompany the series. I think it was this series that launched Anthony Hopkins' career. Wiki
My copy of the original book was a series tie-in
This is the souvenir guide. Pinched this off eBay as mine is now long gone.
