He fought in the Austrian army during the War of the First Coalition, rising in rank from leading a cavalry regiment to commanding a brigade.

Sometime after he turned 26-years-old, Charles became the proprietor of the Royal Allemand Dragoon Regiment, a unit recruited from Germans loyal to the French crown.

After the outbreak of the French Revolution, Charles, his younger brother Joseph, and the entire Royal Allemand Regiment went into exile.
