You find the order books -- I'll work on the maps! I'm actually working on a map now (making very slow progress due to other irons in the fire) of the area of operations of the Indian Territory units (i.e. includes SE KS, SW MO, Western AR, North TX). Many 'points' cannot be know with precision but their generally area can determined.

I am very interested in learning more about the IHG. I have read Britton's books multiple times (may favorite is 'Memoirs of the Rebellion on the Border - 1863"). I have Peck's memoirs from the National Tribune and have, of course, read the ORs many times. There are some other primary sources but quite limited. I do have a copy of their record of events which I assume is in the Supplement to the ORs.
