Maréchal de camp (sometimes incorrectly translated as field marshal) was a general officer rank used by the French Army until 1848.
It was also known in the French army as the "battle sergeant" (fr: sergent de bataille).
However the maréchal de camp was entitled a general's uniform, the brigadier des armées du roi still wore his regiment's uniform.
When the rank of brigadier was abolished in 1788, maréchals de camp assumed command of brigades in the French Army, but kept their two-star insignia.
With the Bourbon Restoration in 1815, the rank of brigade general became once again maréchal de camp, but was changed back again to brigade general after the French Revolution of 1848.
