Fort Loudoun State Park

From Wikipedia:
Fort Loudoun was a British colonial-era fort located in what is now Monroe County, Tennessee, United States. Built in 1756 and 1757 to help garner Cherokee support for the British at the outset of the Seven Years' War, the fort was one of the first significant British outposts west of the Appalachian Mountains. The fort was designed by John William G. De Brahm, its construction was supervised by Captain Raymond Demeré, and its garrison was commanded by Demeré's brother, Paul Demeré. It was named for the Earl of Loudoun, the commander of British forces in North America at the time.

Relations between the garrison of Fort Loudoun and the local Cherokee inhabitants were initially cordial, but soured in 1758 due to hostilities between Cherokee fighters and European settlers in Virginia and South Carolina. After the massacre of several Cherokee chiefs who were being held hostage at Fort Prince George, the Cherokee laid siege to Fort Loudoun in March 1760. The fort's garrison held out for several months, but diminishing supplies forced its surrender in August 1760. Hostile Cherokees attacked the fort's garrison as it marched back to South Carolina, killing more than two dozen and taking most of the survivors prisoner.

The fall of Fort Loudoun led to an invasion of Cherokee territory by General James Grant and an important peace expedition to the Overhill country by Henry Timberlake. The fort was reconstructed in the 20th century based on the detailed descriptions of its design by De Brahm and Demeré, and excavations conducted by the Works Progress Administration, the Fort Loudoun Association, and the Tennessee Division of Archaeology. It was designated a National Historic Landmark in 1965, and is now the focus of Fort Loudoun State Park.
