Indeed Dodger, and given that Nelson was an admiral, it's unlikely he would have been too involved in the action at a land battle like Waterloo, even if he had not expried ten yers previously as you rightly pointed out.
You don;t have to be any kind of a history expert to know that Nelson died on the deck of the Victory at Trafalgar - lord knows if any of the BBC numpties glances skywards on the day, they could see a statue of the great man atop the column that bears his name - in a NAVY uniform!!!!!
