On 12 July 1789, Charles Eugène rode at the head of his dragoons across the Place of Louis XV into the Tuileries Gardens, against a mob that had gathered there and forced the group out of the garden. In the course of the attack, many were injured, and Charles Eugène was held popularly responsible, although no charges were filed. He defended the royal palace in the riot at the Tuileries Gardens in July 1789. Initially he served in the French army, but at the outset of France's wars with Austria, he picked up the Bourbon cause in Germany. When hostilities between France and the Habsburgs reached a crisis point in 1791, he left his Allemand Dragoons and followed the Bourbon cause with his younger brother, Joseph, Prince of Vaudémont.

Bourbon restoration

He died in Vienna in 1825. After the restoration of Louis XVIII, he was created again Peer of France, and his dignities further enhanced by the title Duke of Elbeuf. Louis XVIII furthermore appointed him as a Marshal of France. Because of the popular hostility against him in France, relating to the incident in the Tuileries in July 1789, he never exercised these privileges and he died at the age of 74 in Vienna on 21 November 1825. As he had no children, and with his death, and his brother's, the male line of old Lothringen lines of Erbouf, Harecourt, and Armagnac ended.
