The Green Howards fought at the Battle of Fontenoy in May 1745, with a short period in England during the 1745 Jacobite Rising. It took part in the Battle of Rocoux and the Battle of Lauffeld before the 1748 Treaty of Aix-la-Chapelle ended the war, after which it became part of the garrison of Gibraltar. While there, the 1751 army reforms retitled it the 19th Regiment of Foot. It returned to Britain in 1752 and spent most of the next decade on garrison duty in Scotland and Northern England.
