After John Brown's arrest for raiding the Harper’s Ferry, on the 26th of October, 1859, Maria Child wrote him a letter.

This excerpt from the Maria's letter makes this point very clear:
"[...] I cannot sympathize with the method you chose to advance the cause of freedom. But I honor your generous intentions–I admire your courage, moral and physical. [...]"
