Louisiana Army base renamed after Black WWI hero, replacing Confederate general's name.

Louisiana's Fort Polk, named after Confederate commander Leonidas Polk, has been renamed Fort Johnson to honor Sgt. William Henry Johnson, a Black hero of World War I who posthumously received the Medal of Honor in 2015. Johnson fought off a German night raid near the Argonne Forest, was wounded 21 times, and prevented a wounded Black comrade from being taken prisoner. The renaming of the base represents the latest in a push by the Biden administration to rename military installations honoring Confederate officers.
