Question: Although he was Northern-born, General William Miller led an army for the Confederate side, for which state?

full_context: Document 1: Florida in the American Civil War: Florida joined the Confederate States of America at the beginning of the Civil War, as third of the original seven states to secede from the Union, following Lincoln's 1860 election. With the smallest population, nearly half of them slaves, Florida could only send 15,000 troops to the Confederate States Army. Its chief importance was in food-supply to the south, and support for blockade-runners, with its long coastline full of inlets, hard to patrol.
Document 2: Cooperationists: The Cooperationists were a group formed in the United States in the 1860s. The group was formed after the Election of 1860. Following South Carolina's Secession from the Union, the Cooperationists believed that the remaining slave states should secede at once and at the same time, rather than one at a time, as they believed that doing so would impress the federal government with the seriousness of their resolve. The proposal was rejected, but the Southern States nonetheless seceded in rapid succession. The following is a list of the states that seceded, including the date on which each state seceded: South Carolina (December 20, 1860), Mississippi (January 9, 1861), Florida (January 10, 1861), Alabama (January 11, 1861), Georgia (January 19, 1861), Louisiana (January 26, 1861), Texas (February 1, 1861), Virginia (April 17, 1861), Arkansas (May 6, 1861), North Carolina (May 20, 1861), and Tennessee (June 8, 1861).

He has participated in numerous combat operations, such as; Battle of Mogadishu 1993, and since 2001 the wars in Iraq and Afghanistan.
Document 5: King Cotton: "King Cotton" as a slogan summarized the strategy used before the American Civil War of 1861–1865 by pro-secessionists in the Southern States (the future Confederacy) to claim the feasibility of secession and to prove there was no need to fear a war with the Northern States. The theory held that control over cotton exports would make a proposed independent Confederacy economically prosperous, would ruin the textile industry of New England, and—most importantly—would force Great Britain and perhaps France to support the Confederacy militarily because their industrial economies depended on Southern cotton. The slogan, widely believed throughout the South, helped in mobilizing support for secession: by February 1861, the seven states whose economies were based on cotton plantations had all seceded and formed the Confederacy (C.S.A.). Meanwhile, the other eight slave states, with little or no cotton production, remained in the Union.
Document 6: William Miller (Confederate Army officer): William Miller (August 3, 1820 – August 8, 1909) was an American soldier, attorney, timberman, and politician.

Document 7: American Civil War: The American Civil War (commonly known as the "Civil War" in the United States) was fought in the United States from 1861 to 1865. The result of a long-standing controversy over slavery, war broke out in April 1861, when Confederates attacked Fort Sumter in South Carolina, shortly after Abraham Lincoln was inaugurated. The nationalists of the Union proclaimed loyalty to the U.S. Constitution. They faced secessionists of the Confederate States of America, who advocated for states’ rights to perpetual slavery and its expansion in the Americas.
Document 8: President Lincoln's 75,000 volunteers: On April 15, 1861, at the start of the American Civil War, the President of the United States, Abraham Lincoln, called for a 75,000-man militia to serve for three months following the bombardment and surrender of Fort Sumter. Some slave states refused to send troops against their neighboring slave states, with the result that most such states also declared secession from the United States and joined the Confederate States.
Document 9: William Henry Wallace: William Henry Wallace (March 24, 1827 – March 21, 1901) was a Confederate States Army brigadier general during the American Civil War (Civil War). Before the Civil War, he was a planter, newspaper publisher, lawyer and South Carolina legislator in 1860 who supported the state calling a secession convention. He served in the Eastern Theater of the American Civil War, including service as a brigade commander in the Army of Northern Virginia. After the Civil War, he was a lawyer, planter, South Carolina legislator and circuit judge.
Document 10: Outline of the American Civil War: American Civil War – civil war in the United States of America that lasted from 1861 to 1865. Eleven Southern slave states declared their secession from the United States and formed the Confederate States of America, also known as "the Confederacy." Led by Jefferson Davis, the Confederacy fought against the United States (the Union), which was supported by all the free states (where slavery had been abolished) and by five slave states that became known as the border states.
Document 11: Border states (American Civil War): In the context of the American Civil War (1861–1865), the border states were slave states that did not declare a secession from the Union and did not join the Confederacy. To their north they bordered free states of the Union and to their south they bordered Confederate slave states. Of the 34 U.S. states in 1861, nineteen were free states and fifteen were slave states. Four slave states never declared a secession: Delaware, Kentucky, Maryland, and Missouri. Four others did not declare secession until after the Battle of Fort Sumter and were briefly considered to be border states: Arkansas, North Carolina, Tennessee, and Virginia—after this, they were less frequently called “border states”. Also included as a border state during the war is West Virginia, which was formed from 50 counties of Virginia and became a new state in the Union in 1863.
Document 12: Gerald Miller (missionary): Gerald L. Miller, M. D. (born 1937) is a well-known Mennonite medical missionary who worked with the Eastern Mennonite Missions board to save hundreds of lives in Somalia in the years 1971-1972.

Document 13: William Porcher Miles: William Porcher Miles (July 4, 1822 – May 11, 1899) was among the ardent States' Rights advocates, supporters of slavery, and Southern secessionists who came to be known as the "Fire-Eaters." He is notable for having designed the most popular variant of the Confederate flag, originally rejected as the national flag in 1861, but adopted as a battle flag by the Army of Northern Virginia under General Robert E. Lee before being reincorporated by William Tappan Thompson into the second design of the national flag in 1862.

Document 15: Lambdin P. Milligan: Lambdin Purdy Milligan (March 24, 1812 – December 21, 1899) was a lawyer and farmer who was known for his extreme opinions on states' rights and his opposition to the Lincoln administration's conduct of the American Civil War. Believing that the Confederate states of the South had the power under the U.S. Constitution to secede from the Union, he opposed the war to reunite the nation. Milligan became a leader of the secret Order of American Knights (formerly the Knights of the Golden Circle, and later the Sons of Liberty, and advocated violent revolution against the U.S. government. U.S. Army forces arrested him at his home and tried him and other conspirators by military commission for disloyalty and conspiracy. Found guilty, he was sentenced to death. A habeas corpus appeal made its way from the federal circuit court in Indianapolis to the U.S. Supreme Court, which in 1866 ruled that the application of military tribunals to citizens when civil courts are open and operating was unconstitutional. See "Ex parte Milligan" 71 U.S. (4 Wall.) 2 (1866) . Following the Court's ruling on April 3, 1866, Milligan and the others were released from custody. He returned home and practiced law in Huntington, Indiana, where he later filed a civil suit claiming damages for the military arrest and trial. On May 30, 1871, the jury found in Milligan's favor, but federal and state statutes limited the award for damages to five dollars plus court costs.
