I'm trying to find a primary source (or some historical authentication) for John Quincy Adams' Toledo War quote.?

Question

Never in the course of my life have I known a controversy of which all the right was so clearly on one side and all the power so overwhelmingly on the other. John Quincy Adams is widely credited to have said this regarding Ohio's claim of the Toledo Strip from the Michigan Territory. However, I do not know where or by which medium he said it. Letter? Speech? Editorial?

Answer 1

I believe it was written in his personal diary. You may be able to find it in the Michigan Historical Collections.
