Ken Wright churned out lots of this type of wargame for the Spectrum from CCS. He just changed the map and graphics for each game, and never once hit the polish of Vulcan, perhaps the best wargame there is.
Whilst the system might just work for pre-20th century battles on a single battlefield, the failures of this game show what a dismal attempt of copy and paste this was. Units can only be ordered to move in groups of six as 'armies', and each army can only be directed by pointing out the center and left and right flanks. So if you really need a tank unit to fit into a certain square, forget it. It might do it if it feels like it. Or it might move off in the opposite direction.
Now if this was Napoleanic cavalry on a smoky battlefield, that might make sense (Though be no less annoying). When each square will be some 20-30 miles across, and each turn over several days, all with radio communication, it doesn't work. Plus, because units can only be brought in slowly onto the beaches on the north coast, you never get the chance to fully manoeuver anyway. Not a fun experience at all.
