I will send you the attachment Ken shortly.
The issue of some of the men in the IHG desert and turn up in Confederate units does not strike me as strange though I doubt very seriously if there were many. I compared names to some rosters I have and the names are the same, but that is not definitive proof. I know for a fact that in several of the Kansas Regiments, the 6th Kansas being of particular note, there were men in several of the companies raised from Missouri that deserted to the Rebel side or were working as spies, a common thing in about all of the Missouri State Militia Regiments from the looks of their rosters. We know also from William A. Phillips letters that he had a spy on the Staff of Douglas H. Cooper.
With the desertion of so many men from Drew's Cherokee regiment the Union side was presented with a fait accompli in the form of creating a 3rd IHG regiment and if Britton is to be believed a 4th and a 5th. The facts are clear that the IHG's purpose was to protect the Northern interests in the Indian Territory by combating the likes of Tandy Walker, Watie & Cooper. Sorting out the agendas for this part of the war is quite the challenge.
One of the interesting facets of the Company G Roster and Day book is that we can track the deaths by disease and where they died which gives the Genealogist a profile to work with.
We have for the first time one such roster of 36 muster rolls that are somewhere, other than the CSR's. Where are they and the company Day Books?
