The so-called Secret Six, or the Secret Committee of Six, were a group of men who secretly funded the 1859 raid on Harper's Ferry by abolitionist John Brown. Sometimes described as "wealthy," this was true of only two. The other four were in positions of influence, and could, therefore, encourage others to contribute to "the cause."
The name "Secret Six" was invented by writers long after Brown's death. The term never appears in the testimony at Brown's trial, in James Redpath's The public life of Capt. John Brown (1859), or in the Memoirs of John Brown of Franklin Benjamin Sanborn (1878). The men involved helped Brown as individuals and did not work together or correspond with each other. They were never in the same room at the same time, and in some cases barely knew each other.
Background
The Secret Six were Thomas Wentworth Higginson, Samuel Gridley Howe, Theodore Parker, Franklin Benjamin Sanborn, Gerrit Smith, and George Luther Stearns. All six had been involved in the abolitionist cause prior to their meeting John Brown, and had gradually become convinced that violence was necessary in order to end American slavery.
Of the six, only Smith and Stearns could be called wealthy. The others consisted of two Unitarian ministers (Parker and Higginson), a doctor (Howe) at a time when physicians were not well-to-do, and a teacher (Sanborn). Smith later bailed Jefferson Davis after the Civil War.
To the extent the group had a leader, it was Brown biographer Sanborn. "Some of the money and nearly all the correspondence relating to the contributions passed through my hands in 1858–9. ...[W]e all raised money to aid Brown in carrying this plan forward."
Involvement with John Brown
Brown was planning to capture weapons from a federal armory at Harpers Ferry, Virginia (now West Virginia), and lead a slave rebellion in the South. While it is unclear whether these men knew of Brown's ultimate plan, it is known that some were ambivalent regarding the use of violence as a way to bring about the destruction of slavery. Brown met with members of the Six several times during 1858 and 1859 to discuss how he would attack the slave system.
In October 1859, Brown's plan failed. The question immediately arose of who was backing Brown, as his declarations that the raid was his own idea were not believed. Speculation and then testimony, reported in The New York Times, New-York Herald, and other papers, began to link the names of the Six with Brown's. On November 7, Smith had himself confined to an insane asylum, denying that he had been involved in supporting Brown. Howe, Sanborn, and Stearns fled to Canada temporarily to avoid arrest. Parker was already in Italy, a guest of Robert and Elizabeth Barrett Browning, as it was believed that a warm climate was helpful to those suffering from tuberculosis.
"We did not know that Brown meant to begin there, in Virginia, at Harper's Ferry," Sanborn insisted. Like Gerrit Smith, Sanborn felt justified in making public statements which told a part of the truth, but not the whole truth. "We expected he would go farther west, into a region less accessible, where his movements might escape notice for weeks, except as the alleged acts of some marauding party."
On the night of April 3, 1860, five federal marshals arrived at Frank Sanborn's home in Concord, Massachusetts, handcuffed him, and attempted to wrestle him into a coach and take him to Washington to answer questions before the Senate in regard to his involvement with John Brown. Approximately 150 townspeople rushed to Sanborn's defense. Judge Ebenezer R. Hoar issued a writ of replevin, formally demanding the surrender of the prisoner. In a letter to a friend, Louisa May Alcott wrote, "Sanborn was nearly kidnapped. Great ferment in town. Annie Whiting immortalized herself by getting into the kidnapper's carriage so that they could not put the long legged martyr in."
Parker, dying of tuberculosis, remained in Italy until his death in 1860. Higginson was the sole member of the Six to stay in the United States and to publicly proclaim his support for Brown. He even developed a plan to have Brown rescued from his jail cell, but Brown did not want any part of it. Higginson asked Sanborn upon the latter's absconding to Canada, "Can your clear moral sense justify our holding our tongues in order to save ourselves from the reprobation of society, even as that nobler man whom we did provoke to enter into danger becomes the scapegoat of that reprobation, going for us even to the gallows?"
