In the preliminary treaties signed with France and Spain on 20 January 1783, France and Britain returned to each other nearly all the territories they had taken from each other since 1778, except for Tobago, which the French had captured in 1781 and were allowed to keep. France also gained some territory around the Senegal River in Africa which it had lost to Britain in 1763. The whole arrangement for fishing around the Newfoundland coast had to be renegotiated because of the rights awarded to the Americans.
