More French Guard, here we have Flanquers of the Young Guard. These existed from 1811-13 I believe, being disbanded thereafter with survivors being distributed to other units. They had a different uniform and I understand that they were originally intended as specialist skirmishers, but they became just another Young Guard formation in practice.
There were two regiments, Flanquer Chasseurs and Flanquer Grenadiers. The Chasseurs were created first. For most or all of their existence, these units did not have short swords, unlike other French Young Guard. Nor did they have epaulettes, so Perry French Light Infantry figures are a good match. Flags are from GMB.
