At Richmond and Wilmington…I found the slaves discontented, but despondingly resigned to their fate. At Charleston I found them morose and savagely brooding over their wrongs. They know and they dread the slaveholder’s power. They are afraid to assail it without first effecting a combination among themselves, which the ordinances of the city, that are strictly enforced, and the fear of a traitor among them, prevent. But if the guards who now keep nightly watch were to be otherwise employed—if the roar of hostile cannon was to be heard by the slaves, or a hostile fleet was seen sailing up the bay of Charleston—then, as surely as God lives, would the sewers of the city be instantly filled with the blood of the slave masters. I have had long and confidential conversations with great numbers of the slaves here, who trusted me because I talked with them, and acted toward them as a friend, and I speak advisedly when I say that they are already ripe for a rebellion, and that South Carolina dares not…secede from this Union of States. Her only hope of safety from wholesale slaughter is THE UNION. Laugh the secessionists to scorn, ye Union-loving sons of the north, for the negroes are prepared to “cement the Federal compact” once more—and really it needs it—with the “blood of despots,” and their own then free blood, too, if the “resistance-to-tyrants” doctrine in practice shall call for the solemn and voluntary sacrifice.
