Fighting for Texas: Filibuster James Long, the
Adams-Onis Treaty, and the Monroe
PERHAPS THE MOST LASTING FOREIGN POLICY ACHIEVEMENT OF THE
Monroe administration was the Transcontinental or Adams-Onis

' Neither Samuel Flagg Bemis nor George Dangerfield mention Long in their discussions on
the Adams-Onis treaty. Long also does not appear in Harry Ammon's extensive biography of
Monroe. Long is only mentioned once in the most complete study of the Adams-Onfs treaty, and
even then nothing is said about the resulting correspondence between U.S. and Spanish officials
concerning the expedition. Samuel Flagg Bemis, John Quincy Adams and the Foundatons of
