John Alexander McClernand
1812 – 1900
Who was John Alexander McClernand?
John Alexander McClernand 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.
A close friend and political ally of Abraham Lincoln, McClernand was given permission to recruit a force to conduct an operation against Vicksburg, Mississippi, which would rival the effort of Grant, his department commander. Grant was able to neutralize McClernand's independent effort after it conducted an expedition to win the Battle of Arkansas Post, and McClernand became the senior corps commander in Grant's army for the Vicksburg Campaign in 1863.
