The fanatical figure of John Brown now stalked upon the Kansas battlefield. Spare, gray-bearded, iron-willed, and narrowly ignorant, he was dedicated to the abolitionist cause. The power of his glittering gray eyes was such, so he claimed, that his stare could force a dog or cat to slink out of a room. Becoming involved in dubious dealings, including horse stealing, he moved to Kansas from Ohio with a part of his large family. Brooding the recent attack on Lawrence, Old Brown of Osawatomie led a band of his followers to Pottawatomie Creek, in May 1856. There they literally hacked to pieces five surprised men, allegedly proslaveryites. This fiendish butchery, clearly the product of a deranged mind, besmirched the free-soil cause and brought vicious retaliation from the proslavery forces. Civil war in Kansas, which thus flared forth in 1856, continued intermittently until it merged with the large-scale Civil War of 1861-1865. Altogether, the Kansas conflict destroyed millions of dollars' worth of property, paralyzed agriculture in certain areas, and cost scores of lives.
