I have to admit that the first paragraph of the website indicated to me the content was going to be very biased and 'politically correct'. I read a quote recently that I think rings true: "Patriotism ruins history". One of the articles mentions Watie in command at the 2nd Battle of Cabin Creek -- Gano was the senior commander, not Watie, though Watie was of course over his own troops in the expedition.

Having studied the battles of Pea Ridge and Prairie Grove, I am aware of no evidence that any Osage were present at either battle. This is based on reports in the Official Records, the correspondence of Cooper and Hindman, the Day Book of the 1st Cherokee Mtd Vols (the "Parks' Day Book), and diaries/memoirs of participants.

It is of course possible that individuals who were Osage or other tribes were present and even members of Watie's Regt (1st Cherokee Mtd Vols) but without any evidence to support that, it is pure speculation. What is published as "history" often includes such speculation as if it is "fact". I am open to the discovery of new sources and evidence but until such information surfaces; I must conclude that there was no organized force of Confederate Indians other than Cherokee at Pea Ridge and none at all at Prairie Grove.

The only Indians at Pea Ridge mentioned in primary sources, are the two Cherokee regiments, Watie's and Drew's. The other Indian units were ordered there but didn't arrive in time for the battle.

There were Union Indians at Prairie Grove but no mention of Confederate Indians. Watie was at Webbers Falls and moved up the Cherokee-Arkansas border with about half of his regiment, the balance remaining in camp, but made no contact with Hindman's army and did not venture into Arkansas further than Dutch Mills AR (aka Dutchtown). Hindman ordered Cooper to send all available troops which turned out to be only a couple of hundred predominately Choctaw men at Ft Coffee (near Scullyville) which joined Watie near Evansville AR, moved up the line with him, and then back south to their respective camps. During this expedition, a small engagement occurred as Manus', about 10 miles west of the Arkansas border, between Watie and 'Pins in Federal uniforms' (not clear whether they were actually members of one of the Indian Home Guard regiments -- may have been AWOL).
