I had promised myself that the ACW project was going to be a simple, out the box, generic project. No attempt to model the forces on specific campaigns or battles, just a bog standard blue Union army against a bog standard grey/butternut Confederate one. So reading the excellent WI ACW Digital Guide Vol 3 (which contains a number of excellent articles on what the troops actually wore), I spent most of last night fretting that a goodly number of my Union troops were wearing the uncommon (by mid-war) shell jacket.
So, with 40 out of the 96 my Union army wearing the "uncommon" shell jacket, Anal Attentiveness Disease struck and I dug out the Green Stuff converting them all into wearing the popular sack coat. This might not have been the most necessary thing to do on 28mm high toy soldiers who normally will be viewed from three feet above, but I knew it would bug me once the miniatures were painted and it only took just under an hour. Yes, I am happy now.
