The next action he saw was when the Prussian army crossed the Elbe at Wartenburg on 13 October. Given orders to outflank the right wing of the French, Duke Charles took his brigade across the Elbe and attacked the village of Bleddin and succeeded in driving the French out, taking nine of their cannons and a number of prisoners. On 16 October he fought with distinction at the Battle of Möckern. Leading his brigade in a bayonet charge against the French batteries and columns he succeeded in forcing the section of the line they attacked back but at the cost of his whole brigade almost being taken out with Duke Charles and the other officers all being wounded in the charge.
