THREE:The confederates endeavoured to keep their plans profoundly secret till they were ready to burst at once on the devoted King of Prussia; but Frederick was the last man alive to be taken by surprise. The secret was soon betrayed to him, and, at once waiving his dislike of the King of England, he concluded a convention with him in January, 1756, and bound himself, during the disturbances in America, not to allow any foreign troops to pass through any part of Germany to those colonies, where he could prevent it. Having his treasury well supplied, he put his army in order, and in August of that year sent a peremptory demand to Vienna as to the designs of Austria, stating, at the same time, that he would not accept any evasive reply; but the reply being evasive, he at once rushed into Saxony at the head of sixty thousand men, blockaded the King of Saxony in Pirna, and secured the queen in Dresden. By this decisive action Frederick commenced what the Germans style "The Seven Years' War." In the palace of Dresden Frederick made himself master of the secret correspondence and treaties with France, Russia, and Austria, detailing all their designs, which he immediately published, and thus fully justified his proceedings to the world.Pitt hastened up to town, and was graciously received by the king, who told him that he left the choice of his colleagues entirely to himself. Pitt, as twice before, immediately proposed that his brother-in-law, Lord Temple, should be placed at the head of the Treasury. Temple was summoned from Stowe, but was as haughty and unmanageable as ever. He demanded that all the old Ministers should be dismissed, that Lord Lyttelton should have the Privy Seal, Lord Gower be Secretary of State, etc. Pitt could not accede to these terms. This time he did not throw up the offer of the Premiership to oblige his wrong-headed brother-in-law, who had the overweening idea that he was as great a man as Pitt himself. He stood firm, and, after a long interview at North End, Hampstead, where Pitt had taken a house for the time, Temple set off to Stowe again in high dudgeon, declaring that Pitt had thrown off the mask, and never meant to accept his co-operation at all. Lord Camden advised Pitt to stand fast, throw off the Grenvilles, and save the nation without them. He acted on the advice.
