WALLACE, William Harvey Lamb, soldier, born in Urbana, Ohio, 8 July, 1821; died in Savannah, Tennessee, 10 April, 1862. He removed with his father to Illinois in 1832, and adopted the profession of law, which he was licensed to practise in 1846, but the same year volunteered as a private in the 1st Illinois regiment for the Mexican war. He rose to the rank of adjutant, participated in the battle of Buena Vista and other engagements, and after the peace resumed his profession, becoming district attorney in 1853. In Nay, 1861, he was appointed colonel of the 11th Illinois volunteers, and at the battle of Fort Donelson, in February, 1862, he commanded a brigade in General John A. McClernand's division, with ability that led to his appointment as brigadier-general of volunteers. In the succeeding battle of Shiloh he commanded General Charles F. Smith's brigade, which for six hours withstood the assault of the enemy, and was the last to leave the field. Wallace fell, mortally wounded, in an ineffectual attempt to resist the enemy. See James Grant Wilson's "Sketches of Illinois Officers" (Chicago, 1862).
