Preston Brooks took Charles Sumner’s insults against slavery, South Carolina, and his relation Andrew Butler hard. He would no longer stand for abolitionists or antislavery men, not that Brooks cared for the difference, throwing around slanders as Sumner did. The South Carolinian determined that he must confront Sumner for the sake of honor, demanding an apology that would shame Sumner. Expecting that Sumner would refuse, and refuse a duel, Brooks would then have full justification to strike him as one did a slave and have satisfaction that way. He cared enough about the proprieties to discuss them at least with Lawrence Keitt (D-SC), Henry Edmundson (D-VA), and James Orr (D-SC). None of these congressmen tried to dissuade Brooks. Edmundson even gave him practical advice on how to best attack Sumner by pointing out that chasing him through the Capitol would leave Brooks winded and tired in front of a man considerably larger than himself.
Instead, Brooks sat and rested up within the Senate chamber two days after Sumner concluded his speech. Once the last woman left the gallery, he sprang into action. He caught Sumner seated at his desk, franking copies of the offending speech. Brooks made a brief statement, no more than two sentences, and either finished with his first blow or landed it immediately after. Twenty-nine more strikes of the gutta-percha cane with the golden head. Brooks held it by that end.
Lawrence Keitt came to the Senate that day, expecting to see the fireworks. Henry Edmundson did too, though he seems to have lost interest when Brooks did not immediately lay on and believed Brooks would not act in the immediate future. He departed to chat up a Senator about the proprieties of an attack within the Senate chamber. He remained to that point because Keitt refused his invitation to go off together. Whether Brooks and Keitt arranged it before hand and had an understanding, or Keitt took it on himself, it seems that the other South Carolinian fancied himself Brooks’ backup. As soon as the blows began, Keitt rose his own cane above his head and charged forward, warning off any who came near as he circled the fray.
Brooks kept up, possibly panicking when Sumner tried to rise. The larger man tried to block the cane as he did so, but became trapped beneath his desk until he pulled it from the floor and staggered forward. Senator Robert Toombs saw the conclusion of the caning, from about when the desk came out of the floor onward. The furniture put more distance between Brooks and Sumner
and seemed to give Mr. Brooks better play with his stick, and the next lick after that occurrence was a more effective one, broke the stick, and lessened the resistance of Mr. Sumner
One might expect things to stop there. Sumner, pained, confused, staggering, ceased to put up much of a fight at all. Brooks literally broke his cane across the Senator’s skull. What more did it take?
Mr. Brooks continued his blows rapidly with the part of the stick he held in his hand, until Mr. Sumner sank to the floor in rather a sitting posture. He then ceased, and some of the bystanders, having by this time reached the parties, took Mr. Brooks by the arm and led him a few paces away from Mr. Sumner.
