Angel Barracks have reduced the price of their Grand Manouevre: Black Powder and Blue Steel rules.
From their announcement:
Grand Manouevre: Black Powder and Blue Steel has come down in price.
The aim of the rules is to enable gamers to play some of the larger battles of the period at a tactical level, involving individual regiments, battalions and batteries.
The rules are easy to learn and the game time taken up in calculating the end-effects of a combat is kept as brief as possible. The simultaneous movement, which is subject to recorded orders, is not only more realistic compared to other methods, but it also reduces the playing time of the game.
The command and control rules have been carefully devised to closely represent the ways in which commanders actually gave and received orders. The game is focused on their command decisions and their abilities to react to battlefield situations.
