General Grant had been having trouble with his politically ambitious subordinate General John A. McClernand since before Shiloh but had attempted to work with him. When two other of his senior officers, Generals Sherman and McPherson complained formally about McClernand's "victory speech" of May 30, 1863 and his direct communications with President Lincoln, Grant was forced to act. He relieved McClernand, sent him home, and replaced him as corps commander with General E.O.C. Ord. (By John Osborne)
