German-Americans were the largest ethnic contingent to fight for the Union in the American Civil War[citation needed]. More than 200,000 native-born Germans, along with another 250,000 1st-generation German-Americans, served in the Union Army, notably from New York, Wisconsin, and Ohio. Several thousand also fought for the Confederacy. Most German born residents of the Confederacy lived in Louisiana and Texas. Many others were 3rd- and 4th-generation Germans whose ancestors migrated to Virginia and the Carolinas in the 18th and early 19th centuries.
