Further to the previous answer, the Leib Garde had (as was said) three battalions, two of fusiliers and one of grenadiers. However, most sources have the grenadier battalion with blue cuffs (as per the coat) rather than the white facings of the fusiliers; I have a suspicion that this may have been because it was formed from the grenadiers of the rest of the Bavarian infantry, bar the Kurprinz regiment, which is also listed as having its own grenadiers, but - again this is just my suspicion - these were included within each company (rather like pikemen had been) and were drawn out and assembled in a distinct company per battalion ie more conventional. The Kurprinz grenadiers also had blue cuffs, of the same hue as their uniforms.
The Boismorel/De La Colonie grenadier battalion, was, as noted, part of a larger unit that was never completed; it was supposed to be formed from French refugees/survivors who had joined up with Bavarian forces. Almost all of the infantry was engaged at the disaster at the Schellenburg, prior to Blenheim, and together the twin defeats led to a major downsizing and reconstruction of the Bavarian army.
