The Leicestershire Regiment was a line infantry regiment of the British Army, with a history going back to 1688. The regiment saw service for three centuries, in numerous wars and conflicts such as both World War I and World War II, before being amalgamated, in September 1964 to form the present day Royal Anglian Regiment. After the outbreak of hostilities at the Battle of Lexington and Concord, the regiment embarked for Boston from Ireland in the fall of 1776. It saw action at the Battle of Long Island in August 1776, was part of the reserve at the Battle of White Plains in October 1776 and the Battle of Fort Washington in November 1776. The regiment also took part in the Battle of Princeton in January 1777. It went on to fight at the Battle of Brandywine in September 1777, the Battle of Germantown in October 1777, and the Battle of Monmouth in June 1778. In September 1778, the regiment took part in Grey's raid at New Bedford and Martha's Vineyard, destroying rebel stores and making off with forage and plunder. The reformed regiment was in action again at the Battle of Guilford Court House in March 1781 and surrendered with the rest of Cornwallis's army at the siege of Yorktown in September 1781.
