As an aside, the other four books purchased were:
- Early Photography at Gettysburg, by William Frassanito (1995).
- Devil's Den, A History and Guide, by Garry Adelman and Tim Smith (1997).
- Confederate Monuments at Gettysburg, by David G Martin (1986). I probably wouldn't have gotten this encyclopedia style volume if it had cost much more than the $14.99 that it did, but I am a sucker for a nice cheap hardback, and there is a lot of good information in here.
- Gettysburg Campaign Atlas, Philip Laino (2nd ed, 2009). This is the real gem of the bunch. 482 pages of map after map after map covering everything from the operational overviews of the larger troop movements before and after the battle down to the movements of regiments and batteries minute by minute across individual fields and fences. A treasure trove of detail for a wargamer or map geek.
