The most expensive flag sold at auction is an American Revolutionary War Battleflag (1776–1779), which went to an anonymous buyer on 14 June 2006 for $12,336,000 (£6,707,264), including buyer's premium, at Sotheby's in New York, USA. The regimental standard of the 2nd Continental Light Dragoons was captured by British cavalry officer, Lt. Col. Banastre Tarleton at Pound Ridge, Westchester County, New York, USA, on 2 July 1779 and subsequently shipped to England, where it remained until it was put up for auction by one of his descendants. It is the earliest surviving American flag of any kind with a field of 13 red and white stripes.The flag was one of four rare Revolutionary War battle flags sold at the auction: three other flags, from a Virginia regiment, thought to have been captured at the Battle of Waxhaws, near the border of North and South Carolina, on 29 May 1780, sold for $5.05 million.
