OSBORNE, Thomas 0., soldier, born in Jersey, Licking County, Ohio, 11 August, 1832. He was graduated at the University of Ohio in 1854, studied law with General Lewis Wallace at Crawfordsville, Indiana, was admitted to the bar, and began to practise in Chicago. At the beginning of the civil war he offered his services to the govern-meat and devoted his time and means to the organization of the 39th Illinois regiment, of which he became lieutenant-colonel and afterward colonel. He was sent to the east with his command and ordered to guard the Baltimore and Ohio railroad between Alpine and Great Capacon, West Virginia When "Stonewall" Jackson made his first raid into Morgan county in the state in the winter of 1861-'2, he kept that officer at bay for several hours, although the latter was at the head of a largely superior force, and succeeded in making good his retreat across the Potomac with but slight loss. He took part in the battle of Winchester in April, 1862, served during the operations in Charleston harbor in 1863, accompanied General Benjamin F. Butler up James river in May, 1864, and was severely wounded at Drury's Bluff, losing the use of his right arm. At the siege of Petersburg, Virginia, he commanded the 1st brigade, 1st division, 24th army corps, and on 2 April, 1865, he captured Fort Gregg, the key to the works about Petersburg and Richmond, by one of the most gallant and successful charges of the war. For this service he was made brigadier-general of volunteers. Subsequently by a rapid movement he cut off the Confederate troops from the Lynchburg road and contributed to the capture of Bee's army. This and his other services throughout the war were recognized by promotion to the rank of brevet major-general of volunteers. At the close of hostilities he returned to the practice of his profession in Chicago. In February, 1874, he was accredited as consul-general and minister-resident to the Argentine Republic, which office he held until June, 1885, when he resigned.
