Hello, I absolutely agree with barry, regarding that we certainly can not know every historical detail and after all this is a game (though historical, of course ). I think i was misunterstood in my initial post... I meant creating ad hoc units of grenadiers, not permanent battalions as the danes had... For instance, during the retaking of Namur in 1695 , perhaps some mixed grenadiers group were formed to storm this or that gate or rampart, i don´t know... hehehe.
And think in the scale of the game, i'm painting that converged grenadier unit just to represent a generic "Grand Alliance" grenadier unit mixed together for a concrete task, and i decided to paint different well known regiments for "aesthetical" purposes.
I like to paint my armies to a high level historical degree... BUT i do not want them to be only usefull for a single campaing, like Barry mentioned. For Instance i want my Spanish to be used In Catalonia, Flanders or Italy , or even any colonial adventure or in the previous war of 1683-84 (Reunions War ?) so i apply the old Latin proverb "Veritas estat in medio" the virtue is at the middle point hehe and try to keep my armies historical and flexible
Ray , you are right, it would be imposible to maintain such a unit for more than a single task just for languages issues among others reasons.
Thank you very much for all the serious feedback
pd. I apologize if my english is not perfect sometimes
