Last book I've read was something to do with managing artillery.

I'm a huge American Civil War self professed historian.  Ever since the summer vactaion my family took to Gettysburg, when I was 10 years old, (after picking blackberries all summer.)  I was hooked on the war from that tender age.  I could never get my hands on enough books.  (I started this when computers were called books.)

I have over 10k in personal library on the ACW, and I am still accumulating.

There is something about Gettysburg that for me is sad, all the men who died there. And yet it is a beautiful place. You may have read these.
