Why did john browns plan fail?

Answer 1

John Brown's plan to initiate a slave uprising at Harpers Ferry in 1859 failed primarily due to a lack of adequate support and poor execution. He underestimated the strength of the local opposition and overestimated the willingness of enslaved people to join his cause. Additionally, Brown and his men were quickly surrounded by U.S. Marines led by Robert E. Lee, resulting in his capture and subsequent execution. The failure highlighted the deep divisions in the country and intensified the national debate over slavery.
