I know somebody is going to ask me why the bases with the flags depict only the national colour and not the regimental colour. One reason is that at the end of the day a base with 12 figures on it is just a symbol representing a unit. The unit could be a regiment or a brigade or part of a regiment or part of a brigade depending on what rules I'm using and what level is being represented. Whatever the level of representation I'm never going to be depicting a regiment at 1:1 scale. So if I did put two flags on a base that number of ensigns would be even more grossly out of proportion!
My childhood coincided with the centenary of the American Civil War so there were lots of ACW books published around that time. I also chewed through a lot of bubblegum in order to collect the Civil War News (1962) trading card set. This was another inspiration for a lifelong fascination with this conflict.
