Adelbert Ames

A staunch supporter of political equality for African Americans, Ames' tenure as governor of Mississippi was a longstanding point of controversy in the historiography around Reconstruction, with Dunning School and other "Lost Cause" historians casting him as a villain in American history. Conversely, his cause was championed by Black historians and, from the 1950s onward, other neo-abolitionist writers.
Ames was the penultimate surviving general officer of the Civil War, dying at the age of 97 in 1933. He was outlived only by Aaron Daggett, who died in 1938 at the age of 100. However, because Daggett was a brevet rank brigadier general of volunteers, Ames was the last surviving Civil War general who had held his rank in the regular U.S. or Confederate States army and was also the last surviving general of the conflict who had begun his career in the regular U.S. Army.
