The Battle of Rhode Island grew out of an ambitious attempt to end British occupation of Newport. In the summer of 1778, Major General John Sullivan led American troops onto Aquidneck Island while a newly arrived French fleet under the comte d’Estaing prepared to cooperate from the sea. The operation promised to become the first major joint campaign of the French-American alliance, but difficult coordination, changing plans, and severe weather undermined the siege before a decisive assault could begin.

When the French fleet sailed away for repairs after a storm and British naval maneuvering, many American volunteers departed. Sullivan withdrew northward toward Portsmouth with the remaining army. British and Hessian forces followed, and on August 29 they attacked American positions across the island. Heavy fighting developed around roads, stone walls, hills, and fields. The Americans held key lines and launched counterattacks, preventing the British from breaking the retreat or destroying Sullivan’s force.

Among the defenders was the First Rhode Island Regiment, a unit whose ranks included Black, Native American, and white soldiers. Its men fought on the American right and helped resist repeated assaults by Hessian troops. The regiment’s service has become central to public memory of the battle, although its diverse composition and the circumstances of Black enlistment should not be reduced to a simple celebratory story. Military service offered opportunity and claims to freedom while the new nation still tolerated slavery.

The engagement ended without a clear tactical decision. British troops held Newport, but the Americans completed an orderly nighttime evacuation from the island and preserved their army. The campaign exposed the practical problems of coalition warfare, including communication between commanders with different instructions and expectations. It also demonstrated that Continental and state forces could withstand a strong attack. Newport remained under British control until 1779, when the garrison withdrew to concentrate forces elsewhere.

The marker stands within the broad landscape of the largest Revolutionary War battle fought in New England. Because the action extended across multiple positions, no single plaque captures the entire battlefield. This location should be read as an entry point to a campaign involving naval power, alliance diplomacy, local civilians, and ground combat. The events of August 29, 1778, were neither an uncomplicated American victory nor a rout; they were a hard-fought defense that allowed Sullivan’s army to escape intact.

Preserving open ground on Aquidneck Island is especially important because terrain shaped the battle. Ridge lines, narrow roads, and fields determined where units could form and how the withdrawal was covered. The marker gains meaning when read as part of that connected landscape rather than as an isolated memorial.
