Thanks much. The diagram helps a lot. After seeing on paper what Davis had in mind, I think I can discount that part of Davis's report as him basically trying to show everyone how smart he was by giving some really complex orders. To try that in the heat of battle, in thick brush, with visibility at a minimum, low on ammunition and the enemy within 50 yards, it's obvious that if the Second Brigade had even attempted the maneuver, it would have invited disaster. Throw in the complexity of coordinating the First Division & he could have collapsed the entire line. The Confederate's didn't have enough men to make the mistake a game-changer, given that they were unsupported; but it definitely would have made things interesting.
Again, thanks much for all the help.
