Britannica educates me thus:
"The military verdict in North America was reflected in the preliminary Anglo-American peace treaty of 1782, which was included in the Treaty of Paris of 1783. Benjamin Franklin, John Adams, John Jay, and Henry Laurens served as the American commissioners. By its terms Britain recognized the independence of the United States (and the demise of the American colonies) with generous boundaries, including the Mississippi River on the west. Britain retained Canada but ceded East and West Florida to Spain."
