Harold J. Stone missing from credits (SPOILERS)

I believe I recognize Harold J. Stone as a Cheyenne Indian Chief who has but one line in this movie that is heard onscreen at the big conference after Jeff Chandler's character has run the gauntlet, approximately one hour into the film. He arises & says: "The Cheyenne will not fight in this war!" I'll betcha' that's him. An early role, his line is said with force of will, & his goodly countenance is very powerful in full Chief's attire. Uncredited. I had just finished viewing "The Wrong Man" & a STAR TREK TV series episode featuring him, & his voice is unmistakeable, as well as his imposing presence. IMDB, please update! (Can anybody else confirm?)
