The 49th (Princess Charlotte of Wales's) (Hertfordshire) Regiment of Foot was a line infantry regiment of the British Army, raised in 1743. Under the Childers Reforms it amalgamated with the 66th (Berkshire) Regiment of Foot to form the Princess Charlotte of Wales's (Royal Berkshire Regiment) in 1881. History Early wars The regiment was raised in Jamaica by Colonel Edward Trelawney as Edward Trelawney's Regiment of Foot in 1743 from eight independent local companies. The regiment was ranked as the 63rd Regiment of Foot in 1747 and re-ranked as the 49th Regiment of Foot in 1751. The regiment landed in Ireland in 1764 and remained there until embarking for Newfoundland in 1772. The regiment moved to Boston in June 1775 for service in the American Revolutionary War. It fought at the Battle of Long Island in August 1776, the Battle of White Plains in October 1776 and the Battle of Fort Washington in November 1776. It went on to take part in the Philadelphia campaign, seeing action at the Battle of Brandywine in September 1777, the Battle of Paoli later that month and the Battle of Germantown in October 1777. It was following the British attack on the Americans at Brandywine, where the light company of the regiment took no prisoners and the Americans demanded vengeance, that the regiment decided to insert identifying red feathers in their shako helmets to prevent anyone else suffering on their account. It then sailed for the West Indies in summer 1778 and took part in the British victory at the Battle of St. Lucia in December 1778 before returning to Ireland in 1780. In 1782, the regiment received a county distinction becoming the 49th (the Hertfordshire) Regiment of Foot. French Revolutionary Wars and the War of 1812 In 1793 the members of the regiment were re-designated as marines for service in the French Revolutionary Wars. In that capacity the regiment was sent to garrison Dominica in 1794. After returning to England in 1796, the regiment was sent to Ostend in 1798 to take part in the Anglo-Russian invasion of Holland in August 1799 and saw action at the Battle of Alkmaar in October 1799. It also served under Admiral Hyde Parker at the Battle of Copenhagen in April 1801. After losing its marine designation, the regiment was deployed to Canada in 1802. The regiment served under Major-General Sir Isaac Brock at the Battle of Queenston
