He immigrated to the United States in 1849, settling in Belleville, Ill., and at the outbreak of the Civil war was commissioned major of a battalion in the 2nd Mo. infantry, with which he took part in the actions at Dug springs and Wilson's creek. He was commissioned colonel of the 12th Mo. regiment, Dec. 19, 1861, and commanded a brigade under Gen. John C. Fremont, a division under Gen. Samuel R. Curtis at Pea ridge, in March, 1862, and one of the three divisions of the Army of the Southwest in May of that year. He was commissioned brigadier- general of volunteers, June 9, 1862, and commanded a division in the capture of Arkansas Post and subsequently in the Vicksburg campaign. He commanded the 1st division of the 15th corps of Grant's army in the operations at Chattanooga and at the battle of Missionary ridge, where he particularly distinguished himself, and he subsequently participated in the Atlanta campaign, the march through Georgia, and the campaign of the Carolinas. During the absence of Gen. Logan, from Sept. 1, 1864, to Jan., 1865, he commanded the 15th army corps, Army of the Tennessee, having been promoted major-general, July 23, 1864.
