Discontinued by consolidation with 10th Missouri Cavalry December 4, 1862. Companies "G" and "H" attached to 3rd Missouri Cavalry December 11, 1862." Dyer, Frederick H.

Can any of you tell me about the skirmish (Co. H, 9th Reg.) referenced here? Why was Co. M of the 3rd Regiment posted to Benton Barracks?

U.S. National Cemetery Interment Control Forms, 1928-1962 for William Dennison found on ancestry.com shows he was buried at Jefferson Barracks, Section 39, Grave 4354, but he doesn't show up on a search for burials there (the grave locator). Curious.
