I have the military records of Col. Edwin c. Catherwood (my great, great grand father) and they show he was the commander of the 5th Mo Cavalry, MSM as of 1862 and then became commander of the 13th MIssouri Cavalry thereafter. Yet in this thread he comes up with the 6th MO Cav. Can someone clarify this for me? Is there any source out there or unit history that mentions him?
