and stabbed to death by Henry Thompson and Theodore Wiener, possibly with help from Brown's sons. From there, they crossed the Pottawatomie and, sometime after midnight, forced their way into the cabin of James Harris at swordpoint. Harris had three house guests: John S. Wightman, Jerome Glanville, and William Sherman, the brother of Henry Sherman ("Dutch Henry"), a militant pro-slavery activist. Glanville and Harris were taken outside for interrogation and asked whether they had threatened Free State settlers, aided Border Ruffians from Missouri, or participated in the sack of Lawrence. Satisfied with their answers, Brown's men let Glanville and Harris return to the cabin. William Sherman, however, was led to the edge of the creek and hacked to death with swords by Wiener, Thompson, and Brown's sons. Having learned at Harris's cabin that "Dutch Henry", their main target in the expedition, was away from home on the prairie, they ended the expedition. They returned to the ravine where they had previously encamped. They rejoined the Osawatomie company on the night of May 25. In the two years before the massacre, there had been eight killings in Kansas Territory attributable to slavery politics, and none in the vicinity of the massacre. Brown killed five in a single night, and the massacre was the match to the powder keg that precipitated the bloodiest period in "Bleeding Kansas" history, three months of retaliatory raids and battles in which 29 people died.

Cutler, author of the History of the State of Kansas (1883), the "crowning horror" of the whole Bleeding Kansas period. "The news of the horrid affair spread rapidly over the Territory, carrying with it a thrill of horror, such as the people, used as they had become to deeds of murder, had not felt before. ...The news of the event had a deeper significance than appeared in the abstract atrocity of the act itself. ...It meant that the policy of extermination or abject submission, so blatantly promulgated by the Pro-slavery press, and proclaimed by Pro-slavery speakers, had been adopted by their enemies, and was about to be enforced with appalling earnestness. It meant that there was a power opposed to the Pro-slavery aggressors, as cruel and unrelenting as themselves. It meant henceforth, swift retaliation—robbery for robbery—murder for murder—
