Defensive line question - Waterloo

[KG_RangerBooBoo]

I would put a line of skirmishers across the stream with the infantry right behind them on the opposite side.  If you use two lines of skirmishers, one over and one not, he'll just use his cavalry to overrun your line across the stream.  He can still do it with the formed infantry on the other side but he'll be facing their gunfire the whole trip.  Same if he assaults your skirmisher line with his infantry.  Without your line infantry behind the line of skirmishers he gets them without much difficulty.  You'll get a free shot at his infantry if you're right behind when they might possibly be disrupted plus he'll still have to assault across the stream.
