Very informative Kirby. I am of course disappointed about your revelation on having documents for the new organization rather than the old. I have the rosters of course but I would like to delve into the make up the regiment in the early days. Your advice concerning the commanders is a consideration that I had sensed but did not conclude was an answer. I saw that in the 4th & 8th MSM commanders. Catherwood of the 6th has always been an enigma to me. But now I think I have a fresh approach to look at. Thanks! As for the Cavalry Tactics book, here again I knew of it of course, but only now make all the connections. I know after the war Carlisle Barracks was continued to be used to train cavalry recruits for the cavalry regiments on the frontier, and many of those recruits spoke with no amount of awe of their instructors in their letters to their families. -- If we ever get all of the regiments sorted out it would serve to publish a decent work on the MSM.
