De Bussy's army in the Deccan had Dragoons and Grenadiers a Cheval serving in it, although not in large numbers. The units in De Bussy's army all appear to have been volunteers, mostly raised by Johan-Christian Fischer. For a good summary regarding Fischer, his Chasseurs and other things see Fine & Dandy
The information on the uniforms of De Bussy's troops in general is not consistent. However, there is consistency regarding the Grenadiers a Cheval - blue coats with red cuffs and lapels, and hats. The lace colour is unknown. Gold is suggested, although other units transferring to India did change to silver.
