The King's Own Royal Regiment (Lancaster) was a line infantry regiment of the British Army. It served under various titles and fought in many wars and conflicts, including both the First and the Second World Wars, from 1680 to 1959. In 1959, the regiment was amalgamated with the Border Regiment to form the King's Own Royal Border Regiment. When the American Revolutionary War began in 1775, it was sent to North America; over the next three years, it took part in numerous actions, including Lexington and Concord, Bunker Hill, Long Island and the Battle of White Marsh in December 1777. The first British soldiers to die in the American Revolution were arguably three members of the light company of the 4th Foot, who died at Concord Bridge in 1775. In early 1778, it returned to Saint Lucia where it was part of the garrison during the December 1778 naval battle of St. Lucia, part of the Anglo-French War.
