The War of The Austrian Succession arose from a dispute between three candidates for the Austrian throne and Britain's principal enemies were again France and Spain.The Buffs, the 31st and the 37th Foot fought at Dettingen, which was a great victory and the last occasion on which an English king (George II) commanded his army in battle. George II was also quoted as saying to his wife Caroline on her death bed when she suggested that he remarry - "No I shall have mistresses".
The 31st Foot later received heavy casualties at Fontenoy. The Buffs and the 37th Foot returned to England and helped deal with the second Jacobite rebellion of 1745.
Both regiments formed part of the Duke of Cumberland's Army, which fought Bonnie Prince Charlie at Falkirk and Culloden, although at the end of the War, which was marked by The Treaty of Aix-la-Chapelle, they were back in Flanders.
