John Tyler [SEP] War of 1812
Tyler, like most Americans of his day, was anti-British, and at the onset of the War of 1812 he urged support for military action in a speech to the House of Delegates. After the British capture of Hampton, Virginia, in the summer of 1813, Tyler eagerly organized a militia company, the Charles City Rifles, to defend Richmond, which he commanded with the rank of captain. No attack came, and he dissolved the company two months later. For his military service, Tyler received a land grant near what later became Sioux City, Iowa. Tyler's father died in 1813, and Tyler inherited thirteen slaves along with his father's plantation.
