How would you describe Jacobs's demeanor as she wrote about the experiences in her community in the weeks and months following Nat Turner's rebellion?

The answer to this question can be found in chapter 7 of Incidents in the Life of a Slave Girl by Harriet Jacobs. Jacobs lived in Edenton, NC, a town not far from Southampton County, Virginia, the site of the rebellion led by Nat Turner in 1831. According to Jacobs, the incident terrified white people in this slave society, throwing the town into "great commotion," as whites feared the insurgency begun by Turner might spread to the people they enslaved.
As for her demeanor in relating the incident, she is obviously emotional in her recounting the tortures that many enslaved people experienced as a result of a militia crackdown in the area in response to the Turner rising. She describes "men, women, children . . . whipped until the blood stood in puddles at their feet." But the overall tone of this chapter is ironic. She observes that the fear evoked by Turner's actions was "strange" given that whites generally argued that their slaves were "contented and happy." She goes on to describe the houses of enslaved people in Edenton being ransacked by mobs of militiamen, supposedly looking for weapons or other evidence of a potential uprising. These militiamen, for whom her contempt is obvious, are poor white men, and the irony is that they do not realize, in her words, that "the power which trampled on the colored people also kept themselves in poverty, ignorance, and moral degradation." They thus reveled in the opportunity to show their "subservience" to rich white slaveholders, because they "had no negroes of their own to scourge." The final irony unfolds at the end of the chapter, when Jacobs describes a white church service attended by slaves (their own church being destroyed by the mob). At the end of the service, they took communion, with the minister reminding them that they did so "in commemoration of the meek and lowly Jesus, who said, 'God is your Father, and all ye are brethren.'" Her ironic tone in this chapter reveals many of the contradictions and evils of slavery.
