Little commonality in regard to the names of men from one company not appearing on the roster of the other. There are other measures of commonality--one being that they all lived in the same general area, another being that they were hard-core Unionists who were not averse to attempting to impose their will on neutrals and Southern supporters in aggressive ways. When I use the word "interchangeable" I do not mean that the same men enlisted in both units. many SEMO natives on both sides who belonged to a specific unit had no compunction against tagging along with another unit on a raid. On the Confederate side, Sam Hildebrand is one prime example of a man who could collect men from a variety of different units for a raid. On the Union side, Lt. Erich Pape is another example. Consider, for example, the Federal raid on and burning of Doniphan on Sept. 19, 1864. Men from at least four companies have been identified as having joined with Pape for that episode, most of them being SEMO natives. When SEMO natives had scores to settle, belonging to one unit was no impediment to tagging along with another unit to take care of business.
