Coming off painting a stack of British, I wasn't able to stop painting red coats!
The 4th Swiss fought for the French in both the Peninsula and Russia - these were painted up for a refight of the Battle of Roliça in Portugal in 1808, Wellington's first engagement in Portugal.
I have a bit of background here on my blog https://tinywarsplayedindoors.blogspot.com/2019/01/red-coated-french-swiss-4th-infantry.html Figures are the HaT French Line Infantry.
