The 1739 stono rebellion in south carolina demonstrates that:

The largest and most significant slave rebellion in the British North American colonies, the Stono Rebellion revealed tensions that continued in slave states throughout the next century. Slaves were oppressed by a brutal system of forced labor and sometimes violently rebelled. When the slave owners caught up with the rebels from the Stono River in 1739, they engaged the 60 to 100 slaves in a battle. ... As a result, South Carolina's lawmakers enacted a harsher slave code. This new code severely limited the privileges of slaves.
