Below is a powerful excerpt about how enslaved women refused to comply with the directive to produce more slaves.
Perhaps the most dramatic and least known act of resistance was the refusal of slave women to perform their most essential role, producing baby slaves, for which they were rewarded. "Every woman who is pregnant," observes plantation mistress Frances Kemble, "is relieved of a certain portion of her work in the field...Certain additions of clothing and an additonal weekly ration are bestowed upon the family...The more frequently she adds to the number of her master's livestock by bringing new slaves into the world, the more claims she will have upon his consideration and good will." [Emphasis mine.]
Even so, a Texas slave by the name of Rose Williams tried to resist a forcible mating. When her master placed a healthy specimen by the name of Rufus in her cabin for this purpose, she chased him out with a three-foot poker. Subsequent visits by Rufus met with the same response. Rose Williams finally relented when the master threateningly reminded her that he had purchased her entire family to save them from being separated.
Some slave women, perhaps a significant number, did not bear offspring for the system at all. They used contraceptives and abortives in an attempt to resist the system, and to gain control over their bodies.
Another physician, writing in a Nashville, Tennessee, medical journal, told of a planter who kept between four and six slave women "of the proper age to breed," but in twenty-five years only two children had been born on the plantation. When the slave owner purchased new slaves, every pregnancy miscarried by the fourth month. Finally it was discovered that the women were taking "medicine" supplied by an old slave woman to induce abortions.
