You are probably correct, I have never been into the Napoleon Tactics, I do hate Melee battles.If you're suggesting binoculars here, I'm thinking they weren't invented yet, but I could be wrong. I just can't picture Napoleon or Wellington using binoculars.
But, I was thinking that you could probably do something similar with a telescope image and a black background to cover the rest of the screen.
I got the idea from a screen from the Sid Meier's game a long time ago, there was a screen with a glove and a cigar, I just can't remember what else the screen did!
Just a Thought!
