This is an interesting article, and rules that confuse me in movement. I recall a similar game set I got into in the 1960's – my first AWI game. I was in command of a "battery" of rebel 6 pounders – 2 guns, 4 gunners, that took forever to arrive on the field.
I helped the hostess get hot dogs, baked beans, potato chips and the like to the individual players, until finally I was allowed to place my guns on a road at the edge of the board. I found I was in cannister/grape range – about 400 yards, of the 42nd Black Watch, crossing a steam at a ford in narrow column. I rolled my dice, shot them down to the point that they lost heavily and had to head to the rear.
They then called the game, we ate, and departed. I sequence, 1 shot, done and gone!
Over the years we played that set of rules infrequently, but I remember one player with rebel riflemen who could fire, reload on next 3 sequences unless he moved, and standing in the open. One British play with light dragoons moved in gradually-longer sequences, and ran through over half the riflemen. The rifleman were unloaded, removed if touched by a dragoon. Unit force to leave the board.
These were all Jack Scruby figures, crude by today's standards, but really challenging set of rules, fun for a dedicated gamer – horror for those who just want to throw dice.
