Gentlemen,
this picture gives me a bit headache:
It depicts General Espagne at Heilsberg in 1807. There he commanded a heavy cavalry division with the 4th, 6th, 7th and 8th Cuirassiers. He carries a cuirassier uniform and the regiment behind him is obviously a cuirassier regiment.
But the guy on the most left, isn't it a hussar?
More troubling, is anyone able to identify that regiment on the right?
Its uniform seems to be that of the carabiniers, pretty obviously with the bearskins, but the number 4 on the horse blanket makes it clear that it's the likely the 4th cuirassier regiment as there were only 2 regiments of carabiniers.
Now, made the famous Édouard Detaille such a mistake or what is the explanation for this regiment?
