These uniforms haven't changed much over the 1805-1815 period after the bearskin was introduced. And there is no flag to distinguish the period either. BUT the cockade changes in 1815 for the hundred days. These guys have the 1815 cockade!
Perry Miniatures. Painted in 2010.
There are three 12 pounders and one 6 pounder. Heavy artillery it is! Some guns are fired, others are being loaded.
