Walrus, when it comes to Joseph Lane it's a mixed bag-- yes, on the one hand he fought against the Takelma and sometimes made racist comments about Native Americans; on the other, they respected his bravery and honesty, and as you probably know one chief even  took the name "Chief Joe."
You are also probably aware of the treaty-making event  on top of Table Rock and what happened  to the small group of white men there amidst a large number of Takelma warriors, when the runner arrived with the story of a terrible  murder of Takelma by whites.  Only because of the Takelma's sense of  fairness and  their respect for Lane was there no bloodshed.
No, Joseph Lane was far from the worst of the Southern Oregonians  when it came to "Indian policy", but the terrible truth is that  eventually most all of the "Rogue Indians" were either killed or marched to the reservation up north.  Certainly one of the ugliest eras of Oregon history.
