What an amazing army. I'm slowly getting into Napoleonic Wars and you inspired me to make a Polish force myself, especially now that Perry Miniatures released Duchy of Warsaw boxes.
There’s actually not very good evidence that Vistula legion grenadiers consistently wore the czapka. Several reliable pictures in fact show them wearing the French-style shako. But since there were four Vistula infantry regiments at the formation’s largest extent, it’s quite possible that some units’ grenadiers wore them.
