It is very hard to find good maps for this campaign. Below are a couple of passable examples. Maybe I should just start making my own...
Colonel Edward R.S. Canby, Commander of the Union Department of New Mexico, 1861-62
Colonel John P. Slough, 1st Colorado Infantry
Major (later Colonel) John Chivington, 1st Colorado Infantry
Henry Hopkins Sibley, Commander of the Confederate Army of New Mexico
Colonel John Robert Baylor, 2nd Texas Mounted Rifles, Governor of Arizona Territory
