during the summer of 1758; while Frederick, foiled in an attack on Moravia, drove the Russians back on Poland in the battle of Zorndorf. His defeat however by the Austrian General Daun at Hochkirch proved the first of a series of terrible misfortunes; and the year 1759 marks the lowest point of his fortunes. A fresh advance of the Russian army forced the king to attack it at Kunersdorf in August, and Frederick's repulse ended in the utter rout of his army. For the moment all seemed lost, for even Berlin lay open to the conqueror. A few days later the surrender of Dresden gave Saxony to the Austrians; and at the close of the year an attempt upon them at Plauen was foiled with terrible loss. But every disaster was retrieved by the indomitable courage and tenacity of the king, and winter found him as before master of Silesia and of all Saxony save the ground which Daun's camp covered. [Sidenote: Minden and Quiberon.] The year which marked the lowest point of Frederick's fortunes was the year of Pitt's greatest triumphs, the year of Minden and Quiberon and Quebec. France aimed both at a descent upon England and at the conquest of Hanover; for the one purpose she gathered a naval armament at Brest, while fifty thousand men under Contades and Broglie united for the other on the Weser. Ferdinand with less than forty thousand met them (August 1) on the field of Minden. The French marched along the Weser to the attack, with their flanks protected by that river and a brook which ran into it, and with their cavalry, ten thousand strong, massed in the centre. The six English regiments in Ferdinand's army fronted the French horse, and, mistaking their general's order, marched at once upon them in line regardless of the batteries on their flank, and rolling back charge after charge with volleys of musketry. In an hour the French centre was utterly broken. "I have seen," said Contades, "what I never thought to be possible--a single line of infantry break through three lines of cavalry, ranked in order of battle, and tumble them to ruin!" Nothing but the refusal of Lord John Sackville to complete the victory by a charge of the horse which he headed saved the French from utter rout. As it was, their army again fell back broken on Frankfort and the Rhine. The project of an invasion of England met with the like success. Eighteen thousand men lay ready to embark on board the French fleet, when Admiral Hawke came in sight of it on the 20th of November at the mouth of Quiberon Bay. The sea was rolling high, and the coast where the French ships lay was so dangerous from its shoals and granite reefs that the pilot remonstrated with the English admiral against his project of attack. "You have done your duty in this remonstrance," Hawke coolly replied; "now lay me alongside the French admiral." Two English ships were lost on the shoals, but the French fleet was ruined and the disgrace of Byng's retreat wiped away. [Sidenote: Pitt in America.]
