These senatorial leaders of the slavery crusade in Kansas were the victims of Sumner's bitter invective. He referred to them as the Don Quixote and Sancho Panza of slavery and, as if to prove that this comparison was not a mere momentary inspiration of playful humor but the elaboration of malignant hate, he developed the parallel to its minute details. He described Douglas in his speech defending his report as "piling one mass of elaborate error on another mass and constraining himself to unfamiliar decencies of speech." But he drew hope from the reflection that the Illinois Senator "is but mortal man; against him is immortal principle. With finite power he wrestles with the Infinite and he must fall. Against him are stronger battalions than any marshaled by mortal arm, the inborn, ineradicable, invincible sentiments of the human heart; against him is Nature with all her subtle forces; against him is God. Let him try to subdue these." He compared the Kansas troubles to the barbarous warfare of the Scottish Highlands when blackmail was levied and robberies committed by marauders "acting under the inspiration of the Douglas of other days," and compared Douglas' recent speech to "the efforts of a distinguished logician to prove that Napoleon Bonaparte never existed." Douglas answered with extreme bitterness. He declared that Sumner's speech had been got up like a Yankee bedquilt by sewing all the old scraps and patches together. He pronounced his classic quotations obscene and indecent. "Is it his object," he asked, "to provoke some of us to kick him as we would a dog in the street? * * * * * The Senator from Massachusetts," he declared, "had his speech written, printed, committed to memory, and practiced every night before the glass, with a negro boy to hold the candle and watch the gestures." He charged Sumner with perjury in taking the senatorial oath to his personal grievance and complained that he had been burned and hung in effigy under the advice of Sumner and his brother agitators because of his unswerving devotion to the Constitution. "I wish," he said, "the Senate to bear in mind that in the many controversies in which I have been engaged since I have been a member of this body, I never had one in which I was not first assailed. I have always stood on the defensive. You arrange it on the opposite side of the house to set your hounds after me and then complain when I cuff them over the head and send them back yelping. I never made an attack on any Senator; I have only repelled attacks." He warned Sumner that Butler, who was absent during the speech, would return to speak and act for himself.
