That veil of trees and patches of clearing in places like Chickamauga are telling a story of their own. The difficulty of moving through these woodlands and undergrowth give me a sense of guerilla warfare, tree to tree sniping, clouds of smoke so dense nothing can be seen 25 feet to the fore. Looking at the wilderness, imagine that lonely dirt road leading through an almost impenetrable underbrush with scraggly trees, triproots, and sudden lowlying spots of water. The back on that lonely road you have blue uniforms of compact soldiery shoulder to shoulder across that clearing trying to move and advance. Gettysburg has it high ground, low ground, rocks and rills, streams and creeks, as well as thick woodland and sparsely planted trees. It is these scenes and sounds that give us visions and dreams.I of course love G'burg and Antietam because they are so isolated that you can essentially see the battlefield as a whole, as it was during the war. Unlike Chickamauga, Shiloh, and Stones River which to me are fascinating but are difficult to envision because they are so spread out that it is difficult to envision what your are looking at and reconciling it with a map in a book.
But if I could spend months going over a battlefield, I'd like to study Chancellorsville (and by extension The Wilderness). I would really like to go over Jackson's famous flank march and attack and discuss with the experts the possible consequences of making his famous attack in column instead of line. Also at the Wilderness what would have been the effect of Lee ordering his cavalry to deliberately move to the area between the Orange Plank Rd and the Orange Turnpike and also west of the Orange Turnpike deliberately setting the woods on fire. Could fire do what the ANV could not--destroy the AoP?
