I was inspired to create some French line infantry command stands carrying ensigns as a break from the 1804 pattern flag with its eagle tipped standard. You don’t see too many examples of these, with a search on the Internet only turning up a few ensigns still surviving. The ensigns (ensignes, often confusingly referred to as fanions which were the pennant carried by companies as rallying points), created in 1811 were in response to the directive of 1808, that had limited the eagle to one per regiment.
Here are a few pictures of the results, along with a pic of the HaT set of early to mid war marching French I painted up at the same time. There is lots more information on the fanions, my build, and a sheet of generic ensigns I created on my blog.
