Can anyone here translate a sentence for me? It's for my Napoleonic Wars story - and it's for authenticity purposes. Many thanks!

I work for a doctor who speaks Gaelic. What's the sentence you need translated?

Hi Frances,

It's to describe in Scottish Gaelic (not Irish) 'Red-coated soldiers' or 'redcoats' or the 'soldiers in red'.

Many thanks for any help :)
