On the day before the sack of Lawrence, Republican senator Charles Sumner of Massachusetts delivered a bombastic and wrathful speech, "The Crime Against Kansas," in which he verbally whipped most of the U.S. Senate for complicity in slavery. Sumner singled out Senator Andrew Butler of South Carolina…Two days later, a relative of Butler, Democratic representative Preston Brooks of South Carolina, strode into the Senate chamber, found Sumner at his desk, and struck him repeatedly with a cane. The hollow can broke after five or six blows, but Sumner required stitches, experienced shock, and did not return to the Senate for three years. Brooks became an instant hero in the South, and the fragments of his weapon were "begged as sacred relics." A new cane, presented to Brooks by the city of Charleston, bore the inscription "Hit him again."
