Bruce,
I'm not familiar with the memoirs by Quantrill's men or other Southern guerrillas. Do any of these recount events in the Indian Territory? After the attack on Blunt's headquarters train near Baxter Springs, Quantrill moved south crossing the Arkansas above Ft Gibson, Cherokee Nation and reporting to Brig Gen D.H. Cooper in the northern Choctaw Nation. I've read that the leading men of the Southern Cherokee knew Quantrill, that he may have been staying at Cherokee J.B. Mayes' house prior to Wilsons Creek and accompanied an informal company of Cherokee to the battle.

Livingston was told to look to Stand Watie for supplies and support. A detachment of Watie's regiment were with Livingston for some amount of time -- these may have been Missouri men who were in the 1st Cherokee Mtd Vols.

Can you refer me to first hand accounts that reference their activities in the Indian Territory and/or their cooperation with troops from the Indian Territory?

Thanks.
Ken
