With Douglas’ response answered, Sumner moved to dismiss James Mason. The Virginian “said nothing of argument, and, therefore, there is nothing for response.” He chided Mason for confusing “hard words,” “frowns,” and “scowls” for reasoned debate. He insisted that he had done nothing to earn such behavior, calling it “plantation manners,” and let the matter drop. They exchanged final barbs over plantation manners and, according to The New York Daily Tribune
Mr. MASON was understood to say-the Senator is certainly non compos mentis.
The Tribune, and antislavery papers in general, praised Sumner to the heavens for his Kansas speech. Some of his friendly colleagues in the Senate had advised against insulting senators and states in private, or objected to the tone, but the main opposition came from the usual quarters. Few Democrats liked an attack on the Democracy and its proslavery policy. Nor did Southerners happily suffer attacks upon slavery of any sort. Angry talk filled the streets of Washington.
Sumner may have underestimated the wrath he provoked. He later testified that he had no inkling of his danger
Never, directly or indirectly; nor had I the most remote suspicion of any attack, nor was I in any way prepared for an attack. I had no arms of means of defence of any kind. I was, in fact, entirely defenceless at the time, except so far as my natural strength went. In other words, I had no arms either about my person or in my desk. Nor did I ever wear arms in my life. I have always lived in a civilized community where wearing arms has not been considered necessary.
Sumner’s colleagues didn’t feel so confident of his safety. Henry Wilson, Massachusetts’ other senator, testified later that John Bingham, of the House, came up to him as the Senate adjourned and said:
“You had better go down with Mr. Sumner; I think there will be an assault upon him.”
Wilson didn’t buy it at first, but Bingham insisted that he “heard remarks made, from which I think an assault will be made.” That changed Wilson’s mind and he asked walked over and asked Sumner to hold on
I am going home with you to-day-several of us are going home with you.
With a quick “None of that, Wilson,” Sumner declined. Wilson tried to get Anson Burlingame and Schuyler Colfax to join him in escort duty all the same, but Sumner left by a side door rather than wait. The would-be bodyguards thought he might come back and hung around for a little while before realizing the senator had well and truly left. Sumner may have taken things more seriously, but Wilson admitted that he gave his colleague no reason to believe they worried about Sumner’s safety. He probably thought they just wanted to talk.
Sumner “shot off just as I should any other day.” On his way out, he ran into William Seward. They had dinner plans so Seward suggested that they share the omnibus, essentially a horse-drawn taxi. Sumner begged off on the grounds that he needed to get to the printing office and look over proofs for The Crime Against Kansas in pamphlet form.
