What British Lines Meant
When Clinton issued the Philipsburg Proclamation in 1779, he was making a military calculation: the more enslaved people who fled Patriot plantations, the more the Patriot economy would be damaged. Freedom was an incentive structure, not a principle.
But the people who heard that proclamation and made the decision to run were not making a military calculation. They were making a decision about their lives. We tend to talk about this in aggregate — thousands fled to British lines — in a way that erases the individual decisions, the specific families who split apart, the specific people who calculated the risks and ran anyway.
What the documentary record from Charleston's occupation shows is that the British used the labor of formerly enslaved people extensively for fortification work, supply transport, and support operations. They were not free in any meaningful modern sense — they were exchanging one form of compelled labor for another, with the difference that the British could not legally return them to their former owners. Many died of disease during the occupation, particularly the smallpox epidemic that swept through the city. Some managed to evacuate with the British fleet in 1782 and eventually reached freedom in Nova Scotia, the Bahamas, or Sierra Leone. Many others were re-enslaved when British protection ended.
What I want students to understand is that when we talk about the social history of the Charleston occupation, we're talking about tens of thousands of individual human decisions being made under conditions of extreme uncertainty and danger. The people making those decisions didn't know how the war would end or what British promises were worth. They ran anyway.
