I found an online copy of Rules for the Conduct of the War-Game on a Map, published in 1896. Clearly aimed at the British military or military enthusiast, they used 6 inch to the mile maps and some sort of markers moved around the maps. Referees had a lot of leeway in the games and it does recommend to run refereed games in which the plays only see the units on the table that their subordinates could see. The rules have some interesting ideas about times to recover from morale failures, scouting, and the length of road march columns. I doubt I’d ever play these rules, but they have some interesting ideas, and I just like the “history” of wargaming as well.
