Maybe this one of the quotes you asked for:

12/3/1860 When Congress convened, several Republicans, especially from the mid-western states, “swore by everything in the Heavens above, and the Earth that they would convert the rebel States into a wilderness.”

I believe that would constitute a threat sufficient to begin to raise an army. “Without a little blood-letting,” wrote Michigan’s radical, coarse-grained Senator Zachariah Chandler, “this Union will not be worth a rush.”
