In the United States, Southern Unionists were white Southerners living in the Confederate States of America opposed to secession. Many fought for the Union during the Civil War. These people are also referred to as Southern Loyalists, Union Loyalists, or Lincoln's Loyalists. Pro-Confederates in the South derided them as "Tories". During Reconstruction, these terms were replaced by "scalawag", which covered all Southern whites who supported the Republican Party.
Montgomery C. Meigs (Georgia) was Quartermaster General of the U.S. Army during and after the war, and his ability to keep the Army supplied proved instrumental in ensuring victory.
David Farragut (Tennessee) was made rear admiral in the Union Navy after capturing New Orleans in the spring of 1862.
Sam Houston (Texas), erstwhile President of the Republic of Texas, was governor of Texas during the secession crisis of 1860-1861 and unsuccessfully tried to prevent Texas from seceding.
