He probably was something like that character.So Chief Dan George's character in "The Outlaw Josey Wales" was your great-great-grand poppy?
The Cherokee in the American Civil War were active in the Trans-Mississippi and Western Theaters. In the east, Confederate Cherokees led by William Holland Thomas hindered Union forces trying to use the Appalachian mountain passes of western North Carolina and eastern Tennessee. Out west, Confederate Cherokee Stand Watie led primarily Native Confederate forces in the Indian Territory, in what is now the state of Oklahoma. The Cherokee partnered with the Confederacy in order to get funds, as well as ultimately full recognition as a sovereign, independent state.
Before Indian Removal, the Cherokee Nation was centered in and around the Blue Ridge Mountains—southwestern North Carolina, southeastern Tennessee, western South Carolina and northeastern Georgia. The Cherokee attempted to address their grievances by taking their problems to the American Federal judicial system. In 1830, a delegation led by Chief John Ross defended Cherokee rights before the U.S. Supreme Court in Cherokee Nation v. Georgia. The Indian cases set a precedent in Indian Country but was in vain as the Cherokee Nation was set upon the Trail of Tears. After the removals, the Cherokee Nation was found west of the Mississippi River, and some Cherokee were still found in the Blue Ridge Mountains.
The Cherokee blamed the federal government and former United States President Andrew Jackson for the Trail of Tears. They also had adopted "Southern ways" before their removal from their Appalachia home. A few of them had owned slaves. Therefore, the western Cherokee already disliked the north when in 1860 William Seward, campaigning on behalf of Abraham Lincoln, said that Lincoln would open the Indian Territory for white settlement.
Chief of the Cherokee John Ross was adamant that the Union was not dissolved. However, another leader of the Cherokee, Stand Watie, joined the Confederate cause, and on June 1, 1861, began recruiting for all-Indian units that became part of the Confederate army. Full-blooded Cherokee tended to support Ross (who was primarily Scottish) while the mixed-blooded Cherokee supported the 3/4 Cherokee Stand Watie. Stand Watie in 1862 was elected Chief of the newly declared Southern Cherokee Nation.
For the duration of the war, a series of small battles and constant guerrilla warfare were waged by Cherokee in the Indian Territory. Stand Watie officially became the last Confederate general to end fighting on June 25, 1865 at Fort Towson, in the southeast portion of the Indian Territory. The terms of the armistice allowed Watie and his command, the First Indian Brigade of the Army of the Trans-Mississippi, to demobilize rather than surrender and go home with their arms.
