Any cunning plan on what to do with the "left over" ensigns?
Two of the four ensigns may end up carrying binoculars (correct for the period??) or telescopes, instead of flag poles.
The other two may end up carrying plain union jack flags, because although colours were left behind, I've found evidence that at least one regiment had a plain union jack, as well as plenty of pictorial evidence of such flags flying over camps. But whether these plain flags were actually carried into battle is a moot point ...
