After the Kansas troubles had subsided, John Brown sought some way to make a direct attack on slavery. For many years he had brooded on the matter, in the light of his reading of the Old Testament, and he felt himself called to assail it as the Jewish heroes assailed the enemies of Jehovah and his people. As early as 1847 he had disclosed to Frederick Douglass, during a visit to Brown's home in Springfield, Mass., a plan for freeing the slaves. He did not contemplate a general insurrection and slaughter. But he proposed to establish a fugitive refuge in the chain of mountains stretching from the border of New York toward the Gulf. "These mountains," he said, "are the basis of my plan. God has given the strength of the hills to freedom; they were placed here for the emancipation of the negro race; they are full of natural forts, where one man for defense will be equal to one hundred for attack; they are full also of good hiding-places, where large numbers of brave men could be concealed, and baffle and elude pursuit for a long time.... The true object to be sought is, first of all, to destroy the money-value of slave property; and that can only be done by rendering such property insecure. My plan, then, is to take at first about twenty-five picked men, and begin on a small scale; supply them arms and ammunition, and post them in squads of five on a line of twenty-five miles. The most persuasive and judicious of them shall then go down to the fields from time to time, as opportunity offers, and induce the slaves to join them, seeking and selecting the most restless and daring."
