In Maryland, formerly enslaved people recalled childhood under slavery as a time of abuse, deprivation, fear, family separation, and forced labor. James Pennington remembered the tyranny and abuse of overseers, who took pleasure in torturing enslaved children long before they were old enough for field work and the whip. Josiah Henson, enslaved in Montgomery County, recounted being beaten unconscious by Isaac Riley for touching a book and being threatened with death if he ever did so again, leaving him with a scar he said he would carry to his grave. Richard Mack, who grew up in Charles County, remembered sleeping on a homemade bunk while his mother went daily to the fields and his father mended shoes for enslaved people and others. Frederick Douglass, from Talbot County, wrote that under slavery children inherited the condition of their mothers and were commonly separated from them in infancy; he also recalled that children too young for field work often lacked shoes and proper clothing, receiving only two coarse linen shirts a year and often going naked when those wore out. Harriet Tubman, from Dorchester County, remembered growing up ignorant of liberty and living in constant fear whenever she saw a white man. By 1856, at least 15 boys and girls under the age of 13 were enslaved by Otho Magruder on his plantation, along with 4 identifiable mothers: Abigail, who could also have been a grandmother, Sophy, Susan, and Sally.
