By the time he was 50 years old, Brown was convinced God had selected him as the champion to lead slaves into freedom, and if that required the use of force, well, that was God’s will, too. After the Kansas-Nebraska Act of 1854 gave citizens of those two territories the right to choose for themselves whether the territories would permit or prohibit slavery, Brown, like many abolitionists, moved to Kansas, taking five of his sons with him. Fervent members of the abolition movement were determined that when the territory was ready to enter the Union as a state, it would do so as a free state. On the other side, many defenders of slavery were also pouring into Kansas, in order to secure it for the pro-slavery faction. On May 21, 1856, Missouri "border ruffians" attacked the anti-slavery town of Lawrence, pillaging and burning. Two days later, Charles Sumner, a U.S. Senator from Massachusetts, was severely beaten with a cane on the Senate floor by Senator Preston Brooks of South Carolina because of verbal attacks the virulently anti-slavery Sumner had made on another South Carolinian. Rumors spread that the border ruffians intended to attack the anti-slavery settlers on Pottawatomie Creek, Kansas; Brown and his family were among the abolitionists in this sharply divided area. On the night of May 24, Brown, with four of his sons and two other men, rode to the homes of three pro-slavery settlers near Dutch Henry’s crossing on Pottawatomie Creek; Brown intended to "Sweep the Pottawatomie of all pro-slavery men living on it." They dragged James Doyle and two of his sons, William and Drury, from their farmhouse. When the trio tried to escape, James Doyle was shot down and his sons hacked to death with short sabers. Doyle’s wife, daughter and 14-year-old son John were spared. At the home of Allen Wilkinson, the avengers ignored the pleas of his sick wife and two children and took Wilkinson away as a prisoner. He was soon dispatched with one of the swords. But soon after once the slaves were freed, everyone looked up to him as ''John Brown’s Legacy''
