Major General Gordon Granger was a Union Army officer during the American Civil War. He is best known for his role in the Battle of Chickamauga and for commanding the District of Texas after the war. Granger played a significant part in enforcing the Emancipation Proclamation in Texas, ensuring that enslaved people were informed of their freedom. On June 19, 1865, Granger issued General Order No. 3, which announced the end of slavery in Texas. This event is now celebrated as Juneteenth, a holiday commemorating the emancipation of enslaved African Americans in the United States. Granger's actions helped to solidify his legacy as a key figure in the fight for civil rights.
