The Third Military District of the U.S. Army was one of five temporary administrative units of the U.S. War Department that existed in the American South.
[2] The district was originally commanded by General John Pope[3] until his removal by President Andrew Johnson on December 28, 1867, when General George Gordon Meade took his place.
[4] Meade served at the current location of Fort McPherson until August 1868 after Alabama and Florida were re-admitted into the United States.
Because of the expulsion of Blacks from the Georgia legislature, a new and final military commander was appointed on December 22, 1869, General Alfred Terry.
In February, the Fourteenth amendment was ratified by Georgia and by July it was re-admitted into the Union.
