if the french arent being lead by a high trait general, then the apaches pretty much clean up. if there's not alot of calvary you can pretty much get by with braves and dog soldiers and not lose too many. i think its the spears that do it. even if you don't have alot of archers when they come into range of the spears it kills their moral. the musketeers stay away like you'd expect so if there are really only about 4 to 5 units of heavy infantry then you can out number them and use a couple of braves to hit their flanks and rear and then chase down the musketeers.
