King George II., as well as his second son, the Duke of Cumberland, gave proof of striking bravery on the 17th of July, 1743, at the battle Dettingen, which was disastrous to France, despite the able preparations of Marshal Noailles. An imprudence of his nephew, the Duke de Grammont, decided the fate of the day. But the jealousy which existed between the English and German generals hindered the course of operations. A treaty concluded at Worms, on the 13th of September, between England, Austria and Sardinia, was badly received by Parliament, which, with good reason, deemed it more favorable to the interests of Hanover than to those of England. {192} The name Hanoverian began to be used as an insult, and was applied at times to the king himself. All the influence that Walpole had preserved in Parliament, and his speech in the House of Lords, were necessary to obtain the maintenance of the foreign troops. Lord Wilmington had just died, and at this time it was by the advice of Walpole that Henry Pelham was called to fill his place at the head of the Treasury. One year later, in the month of November, 1744, a division occurred in the cabinet. In spite of the personal favor of the king, Carteret, then Lord Granville, yielded to the influence of Henry Pelham and his brother-in-law, the Duke of Newcastle. War was at length officially declared between France and England. The new ministers lately raised to power in the name of English interests, as against the German proclivities of the king, continued to hire Hanoverian troops. At the opening of the campaign of 1745, the Duke of Cumberland found himself at the head of the allies.
