Input: Question: What state did the battle that Stanley lead an infantry division for the Army of the Mississippi take place? Passage 1:While in service with the Royal Air Force film unit during World War II, Clayton shot his first film, the documentary Naples is a Battlefield (1944), representing the problems in the reconstruction of Naples, the first great city liberated in World War II, ruined after Allied bombing and destruction caused by the retreating Nazis. After the war, he was second-unit director on Gordon Parry's Bond Street (1948) and production manager on Korda's An Ideal Husband (1947). Clayton married actress Christine Norden in 1947, but they divorced in 1953. In the early 1950s, Clayton became an associate producer, working on several of the John and James Woolf's Romulus Films productions, including Moulin Rouge (1952) and Beat the Devil (1953), both directed by John Huston. It was during the making of Moulin Rouge that Clayton met his second wife, French actress Katherine Kath (born Lilly Faess), who portrayed legendary can-can dancer "La Goulue" in the film; they married in 1953, following Clayton's divorce from Norden, but the marriage was short-lived. It was also during this period that Clayton first met rising British star Laurence Harvey, with whom he worked on both The Good Die Young (1954) and I Am a Camera (1955).
 Passage 2:The son of the Russian-born drawing master and watercolourist, Alexander Cozens, John Robert Cozens was born in London. He studied under his father and began to exhibit some early drawings with the Society of Artists in 1767. In 1776, he displayed a large oil painting at the Royal Academy in London. Between 1776 and 1779 he spent some time in Switzerland and Italy, where he drew Alpine and Italian views, and in 1779 he returned to London. In 1782 he made his second visit to Italy, accompanied by the author William Beckford, spending much time at Naples. In 1783 he returned to England. In 1789 he published a set of Delineations of the General Character ... of Forest Trees. He submitted his work to the Royal Academy but it was entirely rejected, being judged as "not proper art". At the age of 42, three years before he died, he suffered a nervous breakdown and was committed to the Bethlem Royal Hospital asylum. The chief physician there was Dr. Thomas Monro who, also being a keen art collector, recognised Cozens' brilliance and bought his collection. Cozens died in London.
 Passage 3:He fought at several battles in Missouri, including the Battle of Wilson's Creek, where he guarded the supply trains. President Abraham Lincoln appointed Stanley as brigadier general September 28, 1861, although the U.S. Senate did not confirm the appointment until March 7, 1862. Fighting in the Western Theater, he participated in the operations against New Madrid, Missouri and the Battle of Island Number Ten. He was involved in numerous major battles, including the Second Battle of Corinth, where he commanded a division of infantry of the Army of the Mississippi, and the Battle of Stones River, in which he led the cavalry of the Army of the Cumberland. On March 11, 1863, Stanley was appointed major general to rank from November 29, 1862. Stanley also led the Union cavalry in the Tullahoma Campaign. He fell ill late in 1863 and missed the Battle of Chickamauga. In 1864, he fought under William Tecumseh Sherman as a division commander in the IV Corps of the Army of the Cumberland during the Atlanta Campaign, and he was promoted to command of the corps when Maj. Gen. Oliver O. Howard was named commander of the Army of the Tennessee. After the capture of the city, instead of employing him marching to the sea, Sherman dispatched Stanley and his IV Corps to Tennessee to help protect the state from invasion by John Bell Hood's Army of Tennessee.
