The Compagnies franches de la marine were an ensemble of autonomous infantry units attached to the French Royal Navy bound to serve both on land and sea. These troupes constituted the principal military force of France capable of intervening in actions and holding garrisons in outre-mer (overseas) from 1690 to 1761. Independent companies of the navy and colonial regulars, were under the authority of the French Minister of Marine, who was also responsible for the French navy, overseas trade, and French colonies.
