But it was decreed that the temper of that strong mind should be tried by both extremes of fortune in rapid succession. Close upon this series of triumphs came a series of disasters, such as would have blighted the fame and broken the heart of almost any other commander. Yet Frederic, in the midst of his calamities, was still an object of admiration to his subjects, his allies, and his enemies. Overwhelmed by adversity, sick of life, he still maintained the contest, greater in defeat, in flight, and in what seemed hopeless ruin, than on the fields of his proudest victories. {235}Having vanquished the Russians, he hastened into Saxony to oppose the troops of the Empress Queen, commanded by Daun, the most cautious, and Landohn, the most inventive and enterprising of her generals. These two celebrated commanders agreed on a scheme, in which the prudence of the one and the vigour of the other seemed to have been happily combined. At dead of night they surprised the King in his camp at Hochkirchen. His presence of mind saved his troops from destruction; but nothing could save them from defeat and severe loss. Marshal Keith was among the slain. The first roar of the guns roused the noble exile from his rest, and he was instantly in the front of the battle. He received a dangerous wound, but refused to quit the field, and was in the act of rallying his broken troops, when an Austrian bullet terminated his chequered and eventual life. The misfortune was serious. But of all generals Frederic understood best how to repair defeat, and Daun understood least how to improve victory. In a few days the Prussian army was as formidable as before the battle. The prospect was, however, gloomy. An Austrian army under General Harsch had invaded Silesia, and invested the fortress of Neisse. Daun, after his success at Hochkirchen, had written to Harsch in very confident terms:--“Go on with your operations against Neisse. Be quite at ease as to the King. I will give a good account of him.” In truth, the position of the Prussians was full of difficulties. Between them and Silesia lay the victorious army of Daun. It was not easy for them to reach Silesia at all. If they did reach it, they left Saxony exposed to the Austrians. But the vigour and activity of Frederic surmounted every obstacle. He made a circuitous march of extraordinary {236}rapidity, passed Daun, hastened into Silesia, raised the siege of Neisse, and drove Harsch into Bohemia.
