For sure there are many tragic stories of this type, as the Indians for some reason resented the Euro-Americans moving in, taking over their lands and moving them out.  We grew up hearing about how the "savages" opposed our Manifest Destiny,  the heroics of the Cavalry, the struggles we had in the "Winning of the West." 

 In Oregon we have historic monuments to whites killed by Indians, such as the "Jedediah Smith Massacre" at Reedsport, the Geisel/Battle Rock monument at Port Orford, etc., but no highway  signage that I know of commemorating Native Americans massacred by whites.  I'd like to see a more balanced, accurate history narrative.
(And  in Eugene, our Parks Department  puts forth that stupid  racist story that Spencer Butte was named for a HBC traveler killed by the Kalapuya!)
