"Jacobite Colonel John O'Sullivan" Topic

I'm intending to paint up a 28mm command stand vignette of Bonnie Prince Charles and his trusted advisor, Colonel John O'Sullivan. Does anyone have any info regarding what French regiment O'Sullivan served in before the '45? I'm sure I've seen him depicted somewhere wearing a grey-white coat with red facings, but not sure how accurate that is.

Thanks for your help.

I always thought the French infantry uniform worn by Peter Finch as Allan Breck Stewart in the Disney film, Kidnapped (1960), was interesting. Not sure of its historical authenticity, but believe it would look great on the wargame table.

The majority of the French line regiments wore the grey-white coat with red or blue facings, a few had white or black facings, so red facings should be a rather safe bet in your case. I have also searched for this info but came up blank…
French Foreign regiments (German, Swiss etc) had the blue coat similar to the one above. The 5(later 6) Irish regiments wore a red coat

and a few other sources don't associate him with any specific Regiment. He was in the household of Marshal Maillebois for a number of campaigns.

Uniform wise he could have worn anything, but an Irish red coat might be possible.

Thanks for the replies, guys. Seems there's not a lot of info on him regarding his earlier service, so whatever I go for I shouldn't have any criticism from the 'uniform police.'
Cheers!
