Bruce, you touch on a subject I've had a number of conversations about...Artillary with the cavalry. Me thinks the rules were broken or at least winked at often. I have not found any other theater where Cavalry officers bought their own cannon ala Lindsay and his Woodruff guns or the sale of Filly guns like happened in Missouri. I've come to the conclusion the rules of the game were "whatever works, get permission or forgiveness after the fact".
