Smallpox Epidemic Among Dunmore's Forces

**Smallpox Epidemic Among Dunmore's Forces, 1776**

In November 1775, John Murray, the Fourth Earl of Dunmore and Royal Governor of Virginia, issued one of the most provocative documents of the early Revolutionary War. Dunmore's Proclamation declared martial law in Virginia and, more controversially, offered freedom to any enslaved person belonging to a rebel who was willing to bear arms in service of the British Crown. The proclamation was a calculated military strategy born of desperation. Dunmore had been driven from the colonial capital of Williamsburg months earlier and was operating from a small naval flotilla off the Virginia coast, lacking the manpower to reassert British authority. By promising liberty to the enslaved, he hoped to simultaneously bolster his own forces and destabilize the plantation economy that sustained the Patriot rebellion in Virginia.

The response was significant. Hundreds of enslaved men, women, and children risked extraordinary danger to reach Dunmore's lines, crossing rivers, slipping past armed patrols, and traversing miles of hostile territory in the hope of securing their freedom. Those who arrived and were fit for military service were organized into what became known as the Ethiopian Regiment, a unit that bore the motto "Liberty to Slaves" across their uniforms. They fought alongside Dunmore's loyalist forces, most notably at the Battle of Great Bridge in December 1775, where Dunmore's combined force suffered a decisive defeat at the hands of Patriot militia. That loss forced Dunmore to abandon Norfolk and retreat entirely to his ships, crowding soldiers, loyalist civilians, and formerly enslaved refugees into a fleet of vessels anchored in the waters of the Chesapeake Bay and the Elizabeth River.

It was in these cramped, desperate conditions that catastrophe struck. In the early months of 1776, a devastating smallpox epidemic swept through Dunmore's crowded fleet. The disease found ideal conditions for its spread aboard the packed ships, where hundreds of people were confined in poorly ventilated holds with little access to clean water, adequate food, or basic sanitation. Medical care was virtually nonexistent, and there were no meaningful quarantine measures available in such close quarters. Smallpox, already one of the most feared diseases of the eighteenth century, moved through the fleet with terrifying speed.

The epidemic fell with particular ferocity on the formerly enslaved refugees who had answered Dunmore's proclamation. Many of these individuals had little or no prior exposure to smallpox, making them especially vulnerable. Estimates suggest that as many as half of the enslaved people who had managed to reach Dunmore's lines perished from the disease. The Ethiopian Regiment, which had represented both a military unit and a powerful symbol of Black resistance to slavery, was decimated. Civilian refugees — including women, children, and elderly individuals who had fled bondage seeking the protection of the British — died in appalling numbers. Bodies were buried at sea or on the shores of small islands along the coast.

The epidemic effectively destroyed Dunmore's military viability in Virginia. His forces, already weakened by the defeat at Great Bridge, were reduced to a shadow of what he had hoped to assemble. His ability to recruit additional enslaved people was crippled, both because word of the deadly conditions aboard his ships spread through the enslaved community and because Patriot authorities intensified their efforts to prevent further escapes. By the summer of 1776, Dunmore abandoned Virginia altogether, sailing first to New York and eventually returning to England. His brief campaign was over.

The smallpox epidemic among Dunmore's forces matters in the broader story of the Revolution for several reasons. It reveals the enormous risks that enslaved people were willing to take in pursuit of freedom, and it exposes the tragic inadequacy of the promises made to them. Dunmore had offered liberty, but he lacked the resources, infrastructure, and perhaps even the genuine commitment to protect those who answered his call. The epidemic also demonstrated how disease could shape military outcomes as decisively as any battle, a reality that would haunt both sides throughout the war. George Washington himself would eventually order the inoculation of Continental Army troops against smallpox, having recognized the disease as a strategic threat equal to British arms.

For the people who fled slavery to join Dunmore's forces, the epidemic was a cruel and devastating injustice. They had risked everything — leaving behind families, homes, and the only lives they knew — for the chance at freedom, only to die in squalid conditions aboard ships that became floating graveyards. Their courage and their suffering deserve to be remembered not as a footnote to Dunmore's failed campaign but as a central and deeply human chapter in the story of the American Revolution.
