I just joined this forum today. I learned of CWi via a blog post at Bullrunnings. I research the 13th Massachusetts Volunteer Infantry, and have a lot of material on them. I maintain a website 13th Massachusetts Volunteers
The site is 3 years old, and I don't promote it much, but I'm adding detailed history pages to the site, in chronological order. Presently, I'm working on a new page for the battle of Antietam.
I'm usually busy with the website and my blog, (which is linked from the website), so I probably won't have as much time as I'd like to participate in the discussion forums here, but I always welcome correspondence via my email account.
For those interested, here is a picture of some of the officers of the 13th in camp at Williamsport, MD, winter of 1861-62. I've been able to identify several of the soldiers. The gentleman with the 'x' at his feet is Charles B. Fox, who later became an officer of the 55th Mass.
