On May 19, 1856, Senator Charles Sumner was giving his "Crime Against Kansas" speech. During Sumner's speech he was addressing the issue of whether Kansas should be entered as a slave or free state into the union. Charles Sumner was a republican so he was supporting Kansas as a free state.
The Senator does not seem to see any rule excluding a man on account of color is a insult, and a wrong. He makes himself on the floor the representative of insult, and of wrong to the colored race.
Also during Sumner's speech he very much attacked at senator Stephan A. Douglas of Illinois and Andrew Butler of South Carolina and named them the two main culprits of the crime. This enraged Representative Preston Brooks and made him violent.
What did he say?? I hate Him!!
Of course he has chosen a mistress to whom he has made his vows, and who, though ugly to others, is always lovely to him. Though polluted in the sight of the world, is plain in his sight.
3 days after Sumner's "Crime Against Kansas" speech on May 22, 1856, Preston Brooks walked into the Senate Chamber where he found Sumner working. Preston Brooks used his cane and slammed it against Sumner's head.
Preston Brooks continued to beat Sumner and Sumner fell to the floor desperate to protect himself.
After a while, Charles Sumner was knocked unconscious and was bleeding a ton. Preston Brooks walked out of the senate chamber calmly.
Over that night both of them became a hero. Charles Sumner would recover from his injuries and work for the senate 18 years before dying from a heart attack on March 11, 1874. Preston Brooks would die much sooner on January 27, 1857.
