Odd Language #188: Proving for Whom?

‘Kurt snorted. “That they do not tell you until just before you take your first run. I do not want to know why. But I do know that I am not going to be sent into any wilderness where a savage may run a spear through me just to prove something or other for Major John Kelgarries, or for Millaird either. I will try my plan first.”‘ — The Time Traders, chapter 3 by Andre Norton

The issue: Yet another misplaced modifier. The way it reads Kurt is complaining about a savage trying to prove something for the major. This story is available at Project Gutenberg. Here is the link for The Time Traders.
