Retired 1st Sgt. Mark Matthews, 111, one of the last of the nation's legendary Buffalo Soldiers, died of pneumonia Sept. 6 at Fox Chase Nursing Home in Washington. Sgt. Matthews, who also was the oldest Buffalo Soldier, was heir to a proud military heritage that originated with the black soldiers who fought in the Indian wars on the Western frontier. Historians say that the Cheyenne, Kiowa and Apache tribes bestowed the appellation because the soldiers' black, curly hair reminded them of a buffalo's mane.
