The pro-war faction was led by Carteret, who claimed that French power would increase if Maria Theresa failed to succeed to the Austrian throne. George agreed to send 12,000 hired Hessian and Danish mercenaries to Europe, ostensibly to support Maria Theresa. Without conferring with his British ministers, George stationed them in Hanover to prevent enemy French troops from marching into the electorate. The British army had not fought in a major European war in over 20 years, and the government had badly neglected its upkeep. George had pushed for greater professionalism in the ranks, and promotion by merit rather than by sale of commissions, but without much success. An allied force of Austrian, British, Dutch, Hanoverian and Hessian troops engaged the French at the Battle of Dettingen on 16/27 June 1743. George personally accompanied them, leading them to victory, thus becoming the last British monarch to lead troops into battle. Though his actions in the battle were admired, the war became unpopular with the British public, who felt that the king and Carteret were subordinating British interests to Hanoverian ones. Carteret lost support, and to George's dismay resigned in 1744.Tension grew between the Pelham ministry and George, as he continued to take advice from Carteret and rejected pressure from his other ministers to include William Pitt the Elder in the Cabinet, which would have broadened the government's support base. The king disliked Pitt because he had previously opposed government policy and attacked measures seen as pro-Hanoverian. In February 1746, Pelham and his followers resigned. George asked Lord Bath and Carteret to form an administration, but after less than 48 hours they returned the seals of office, unable to secure sufficient parliamentary support. Pelham returned to office triumphant, and George was forced to appoint Pitt to the ministry.George's French opponents encouraged rebellion by the Jacobites, the supporters of the Roman Catholic claimant to the British throne, James Francis Edward Stuart, often known as the Old Pretender. Stuart was the son of James II, who had been deposed in 1688 and replaced by his Protestant relations. Two prior rebellions in 1715 and 1719 had failed. In July 1745, the Old Pretender's son, Charles Edward Stuart, popularly known as Bonnie Prince Charlie or the Young Pretender, landed in Scotland, where support for his cause was highest. George, who was summering in Hanover, returned to London at the end of August. The Jacobites defeated British forces in September at the Battle of Prestonpans, and then moved south into England. The Jacobites failed to gain further support, and the French reneged on a promise of help. Losing morale, the Jacobites retreated back into Scotland. On 16/27 April 1746, Charles faced George's military-minded son Prince William, Duke of Cumberland, in the Battle of Culloden, the last pitched battle fought on British soil. The ravaged Jacobite troops were routed by the government army. Charles escaped to France, but many of his supporters were caught and executed. Jacobitism was all but crushed; no further serious attempt was made at restoring the House of Stuart. The War of the Austrian Succession continued until 1748, when Maria Theresa was recognized as Archduchess of Austria. The peace was celebrated by a fête in Green Park, London, for which Handel composed Music for the Royal Fireworks.
