Yes, I included estimates for partisans, though I specifically excluded "Bloody Bill" Anderson's command, as in various letters he specifically claimed no loyalty to the Confederacy. Many of the partisans were led by officers, including Quantrill, who carried Confederate commissions and hence ought to be counted as Confederate soldiers (though I have my doubts as to how the officers, let alone the enlisted men, of Longstreet's or Hardee's corps, or for that matter Cockrell's brigade, would feel being lumped into the same category as William C. Quantrill--I suspect they'd be so offended that I'd spend the rest of my life, what little of it might exist against veteran combat soldiers, in various duels for offending them).

Others, like Hildebrand, weren't Confederate, but rather had their commissions signed by officers of the Missouri State Guard and, hence, should not be counted as Confederates but rather as Guardsmen (for my research, I count the Guard as separate, as thousands of men served in the Guard but for a variety of reasons would not serve the Confederacy).

And, I've not counted ones that were clearly just freebooters without loyalty to any side, but those were comparatively few (frankly, I think Hildebrand belongs in that category too, but he apparently had a commission from M. Jeff Thompson, and so must be counted as an "officer and a gentleman" even though it's patently obvious he was neither). The contribution of these thugs is nil if not negative as they discouraged service in the Confederate forces. Anderson and his murderous gang clearly fits this category.

It's been several years since I did the estimate, but if I recall correctly, I estimated that some 3,000 Missourians served in the Confederate partisans exclusively (as compared with, for example, so many of Quantrill's men who served in the Regulars upon various occasions and were considered to have been counted there rather than in the partisans). Hence, this category means that they fought the Union but had no direct and formal connection with any regular Confederate organization.

There were probably about 2,000 "nightriders" who served no flag whatsoever, but were simply thieves and murderers (actually, I tend to classify a fair number of Yankees, especially Jennison's folks, in this kind of category when counting for the Union). These folks were purely out to settle personal grudges or were conducting war on a "for profit" basis. To think of these folks as Southern soldiers is sort of like thinking that Dillinger and Barrow were "bank examiners" or that bin Ladin is a "religious reformer."
