Soon thereafter Henson received orders to go with Amos Riley carrying a cargo to New Orleans. This suggestion was enough. He contrived to have his manumission papers sewed up in his clothing prior to his departure on the flat boat for New Orleans. He knew what awaited him and his mind rapidly developed into a sort of smoldering volcano of pent-up feeling which at one time all but impelled him to murder his white betrayers. Blinded by passion and stung by madness, Henson resolved to kill his four companions, to take what money they had, then to scuttle the craft and escape to the North. One dark night within a few days' sail of New Orleans it seemed that the opportune hour had come. Henson was alone on the deck and Riley and the hands were asleep. He crept down noiselessly, secured an ax, entered the cabin, and looking by aid of the dim light, his eye fell first on Riley. Henson felt the blade of the ax and raised it to strike the first blow when suddenly the thought came to him, "What! Commit murder, and you a Christian?" His religious feeling and belief in the wonderful providence of God prevented him. Riley talked later of getting him a good master and the like but did not disguise the effort to sell him. Fortunately, however, Amos Riley was suddenly taken sick and becoming more dependent on Henson then, than Henson had been on him, he immediately ordered Henson to sell the flat boat and find passage for him home in a sick cabin at once. Henson did this and succeeded by careful nursing to get Amos back to his home in Kentucky alive. Although he confessed that, if he had sold Henson, he would have died, the family showed only a realization of an increased value in Henson rather than an appreciation of his valuable services. He, therefore, decided to escape to Canada. His wife, fearing the dangers, would not at first agree to go, but upon being told that he would take all of the children but the youngest, she finally agreed to set out with him. Knowing of the hardships that they must have to experience, Henson practised beforehand the carrying of the children on his back. They crossed the river into Indiana and proceeded toward Cincinnati, finding it difficult to purchase food in that State, so intensely did the people hate the Negro there. After two weeks of hardship, exhausted they reached Cincinnati. There they were refreshed and carried 30 miles on the way in a wagon. They directed themselves then toward the Scioto, where they were told they would strike the military road of General Hull, opened when he was operating against Detroit.
