John Alexander McClernand

John Alexander McClernand (May 30, 1812 – September 20, 1900) was an American lawyer and politician, and a Union general in the American Civil War. He was a classic case of the politician-in-uniform coming into conflict with career Army officers, graduates of the United States Military Academy. He was a prominent Democratic politician in Illinois and a representative in the U.S. Congress before the war and then served as a subordinate commander under Ulysses S. Grant in the Western Theater, fighting in the battles of Belmont, Fort Donelson, and Shiloh in 1861–62.
