Re: What was never done before for napoleonic period?british infantry in square formation and French
No mention has been made of Naval operatives.
Yes there was the HaT set with a few marines but it was over spread with gunners and sailors (no officers or petty officers). Amphibious operations were a specialty of the Royal Navy during this period.
This would be also of use for the American phase of the War of 1812 (post Invasion of Canada) as
amphibious were quite common. Imagine being able to model your own 'burning of the presidential palace in Washington'.
Like their land counterparts their uniforms changed during this period. Taking it a step further, you could also have American Marines ( green uniforms) to reenact Bernard Cornwell's 'the Fort'
However, you would need more Scots (without kilts this time) and that might upset those out there who object to Scots figures.
Forgot to mention with the American marines the 'extra figure' could be an English bull dog.
