A significant strategic advantage for the Americans during the Battle of Yorktown was Naval support from the French.

A key strategic benefit for the Americans in the Battle of Yorktown was the naval assistance provided by the French. The French fleet successfully obstructed British reinforcements and supplies, effectively encircling General Cornwallis’s troops on land. This naval blockade was vital in restricting the British's capacity to maneuver and resupply, enabling American and French forces to coordinate their siege efficiently. The partnership between American troops, under the command of General George Washington, and their French allies highlighted the significance of international alliances in achieving military success. Ultimately, this support was instrumental in securing the decisive victory that advanced American independence.
