The first British settlement in what is now Tennessee was built in 1756 by settlers from the colony of South Carolina at Fort Loudoun, near present-day Vonore. Fort Loudoun became the westernmost British outpost to that date. The fort was designed by John William Gerard de Brahm and constructed by forces under British Captain Raymond Demere. After its completion, Captain Raymond Demere relinquished command on August 14, 1757 to his brother, Captain Paul Demere. Hostilities erupted between the British and the neighboring Overhill Cherokees, and a siege of Fort Loudoun ended with its surrender on August 7, 1760. The following morning, Captain Paul Demere and a number of his men were killed in an ambush nearby, and most of the rest of the garrison was taken prisoner.
