I just got the latest Raid book from Osprey, Tomahawk and musket.
As I just got it I really cant give you more than my first impression about it.
I got it to give inspiration for scenarios to game and I think it will do that just perfect.
It seems to give some back story, some maps of battles or raids and you will get some uniform guides. It also seems to have more color pictures then the standard Osprey publications.
