It was plain that war could not much longer be delayed; and the King's thoughts turned as usual to his continental dominions. Although the importance of the crisis was universally felt, he was content to leave England in the hands of a regency; and as soon as Parliament was over, just before Boscawen sailed, he hurried to Hanover. Next to France, the object of George's dread was Prussia. More than one cause of quarrel had arisen with that country. Frederick had refused to assist in securing the election of the Archduke Joseph (afterwards Joseph II.) as King of the Romans, a project which Newcastle and George had deeply at heart, believing that it would preserve the European balance and strengthen Austria against the French. Deprived of Frederick's assistance, the plan came to nothing. In 1753, again, a dispute had arisen about some ships captured in the late war, and condemned, as Frederick asserted, unjustly by the English Admiralty courts. To such an extent had the irritation against Prussia increased, that it was confidently believed that Frederick intended to assist the Pretender in another attack upon England, taking advantage of the disturbance to secure Hanover for himself. Against Prussia, therefore, George began contracting great subsidiary treaties with the continental princes. The most important of these were with Hesse and with the Czarina of Russia. A factory, says Horace Walpole, was opened at Herrnhausen, where every prince that could muster and clothe a regiment might traffic with it to advantage. [Sidenote: They are opposed by Pitt.] It became Newcastle's duty to carry these contracts through Parliament. He knew the opposition they were certain to meet with, and the necessity of finding some strong support in the Lower House; but his Cabinet was there represented by no man of mark. He had recourse to Pitt, who held the office of Paymaster, but he positively refused to support the subsidies. His colleague Legge went further, and refused to sign the warrants which were to open the Treasury. Newcastle had then recourse to Fox, and succeeded in securing his services by removing Robinson, and making Fox Secretary of State. But the introduction of the address at the opening of Parliament in the autumn, when the Russian and Hessian subsidies were recommended, was the signal for an open mutiny in the ministerial camp. It was attacked in vehement words by Pitt, who, in a well-known passage, likened the new coalition to the junction he had once seen of the Rhone and the Saône; the one a gentle, feeble, languid stream of no depth, and the other a boisterous, impetuous torrent. Newcastle had no alternative but to discharge both Pitt and Legge from their offices. [Sidenote: The French capture Minorca. May 1756.]
