Castle Island: New Nation, New Realities


Plantation owners retained merchant John Codman, of Massachusetts, to transport most of the slaves back to South Carolina. The Pawley family waited until the end of the war to make claims.


“It was the opinion of the court that there was no legal ground for their detention in prison and that we consequently are obliged to liberate them.”

-  Chief Justice William Cushing, 1783

Governor John Hancock
After the Revolution an agent for the Pawley family demanded of Massachusetts Governor John Hancock that the remaining South Carolina slaves be returned. After the war, the practice of slavery had been ended in Massachusetts through court decisions. Hancock referred the case to the Massachusetts Supreme Judicial Court. By then many former slaves had already fled, joining the state’s free black population.

Justice Cushing’s Decision
Chief Justice Cushing ruled against detaining former slaves. In an explanatory letter to South Carolina, he avoided the terms “slaves” and “property” (not wishing to acknowledge the institution of slavery.) Cushing characterized those remaining in Massachusetts as servants or laborers bound by a service contract. While the Pawley’s were entitled to their service, Massachusetts had no obligation to hold them or pay for their return. The practical effect was to free the “Pawley” slaves because the family did not have the resources to recover them.

Some of the South Carolina captives worked as house servants in John Hancock’s Beacon Hill home, pending resolution of their case.

Constitutional Issues
South Carolina Governor Benjamin Guerard bitterly objected, characterizing the Massachusetts response as “puritanism” - imposing morality on others. Some argue that this incident influenced the later debate regarding the fate of “fugitive slaves” at the 1789 Constitutional Convention in Philadelphia.

Before the war
Prince Hall, a prominent African-American activist, joined a British army masonic lodge at Castle Island. He had been rejected by white masons in Massachusetts. Still, Hall supported the Revolution when the war for independence began.
