The Chesapeake–Leopard Affair created uproar among Americans and strident calls for war with Great Britain, but these quickly subsided. President Thomas Jefferson initially attempted to use this widespread bellicosity to diplomatically threaten the British government into settling the matter. The United States Congress backed away from armed conflict when British envoys showed no contrition for the Chesapeake affair and delivered proclamations reaffirming impressment. Jefferson's political failure to coerce Great Britain led him towards economic warfare: the Embargo of 1807.
