Meanwhile the courage of the nation had sunk very low. There was a dread of an immediate French invasion; and the Government so thoroughly lost heart as to request the King to garrison England with Hanoverian troops. This dread was kept alive by a simulated collection of French troops in the north. But, under cover of this threat, a fleet was being collected at Toulon, with the real design of capturing Minorca. The ministry were at last roused to this danger, and Byng was despatched with ten sail of the line to prevent it. Three days after he set sail the Duke de Richelieu, with 16,000 men, slipped across into the island, and compelled General Blakeney, who was somewhat old and infirm, to withdraw into the castle of St. Philip, which was at once besieged. On the 19th of May--much too late to prevent the landing of Richelieu--Byng arrived within view of St. Philip, which was still in the possession of the English. The French Admiral, La Galissonnière, sailed out to cover the siege, and Byng, who apparently felt himself unequally matched--although West, his second in command, behaved with gallantry and success--called a council of war, and withdrew. Blakeney, who had defended his position with great bravery, had to surrender. [Sidenote: Newcastle resigns. Nov. 1756.] The failure of Byng, and the general weakness and incapacity of the ministry, roused the temper of the people to rage; and Newcastle, trembling for himself, threw all the blame upon the Admiral, hoping by this means to satisfy the popular cry. But Fox, his chief supporter, was in no mood to risk anything by fidelity to so weak a chief. He therefore resigned the Seals; and as Murray insisted upon either resigning or being made Lord Chief Justice (which office was given him), Newcastle, without support in the Commons, found himself obliged to resign also.
