Frederick now hastened in person to the scene of danger, leaving his brother, Henry, to make head against Daun. On the banks of the Oder at Kunersdorf, not far from Frankfort, the King attempted to obstruct the passage of the enemy, in the hope of annihilating him by a bold manœuvre, which, however, failed, and he suffered the most terrible defeat that took place on either side during this war (August 12, 1759). He ordered his troops to storm a sand-mountain, bristling with batteries, from the bottom of the valley of the Oder; they obeyed, but were unable to advance through the deep sand, and were annihilated by the enemy's fire. A ball struck the King, whose life was saved by the circumstance of its coming in contact with an étui in his waistcoat pocket. He was obliged to be carried almost by force off the field when all was lost. The poet Kleist, after storming three batteries and crushing his right hand, took his sword in his left hand and fell while attempting to carry a fourth.
Soltikoff, fortunately for the King, ceased his pursuit. The conduct of the Russian generals was, throughout this war, often marked by inconsistency. They sometimes left the natural ferocity of their soldiery utterly unrestrained; at others, enforced strict discipline, hesitated in their movements, or spared their opponent. The key to this conduct was their dubious position with the Russian court. The Empress, Elizabeth, continually instigated by her minister, Bestuzheff, against Prussia, was in her dotage, was subject to daily fits of drunkenness, and gave signs of approaching dissolution. Her nephew, Peter, the son of her sister, Anna, and of Charles Frederick, Prince of Holstein-Gottorp, the heir to the throne of Russia, was a profound admirer of the great Prussian monarch, took him for his model, secretly corresponded with him, became his spy at the Russian court, and made no secret of his intention to enter into alliance with him on the death of the Empress. The generals, fearful of rendering themselves obnoxious to the future emperor, consequently showed great remissness in obeying Bestuzheff's commands.
Frederick, however, although unharassed by the Russians, was still doomed to suffer fresh mishaps. His brother, Henry, had, with great prudence, cut off the magazines and convoys to Daun's rear, and had consequently hampered his movements. The King was, notwithstanding, discontented, and, unnecessarily fearing lest Daun might still succeed in effecting a junction with Soltikoff and Laudon, recalled his brother, and by so doing occasioned the very movement it was his object to prevent. Daun advanced; and General Finck, whom Frederick had despatched against him at the head of ten thousand men, fell into his hands. Shut up in Maxen, and too weak to force its way through the enemy, the whole corps was taken prisoner. Dresden also fell; Schmettau, the Prussian commandant, had, up to this period, bravely held out, notwithstanding the smallness of the garrison, but, dispirited by the constant ill-success, he at length resolved at all events to save the military chest, which contained three million dollars, and capitulated on a promise of free egress. By this act he incurred the heavy displeasure of his sovereign, who dismissed both him and Prince Henry.
Fortune, however, once more favored Frederick; Soltikoff separated his troops from those of Austria and retraced his steps. The Russians always consumed more than the other troops, and destroyed their means of subsistence by their predatory habits. Austria vainly offered gold; Soltikoff persisted in his intention and merely replied, "My men cannot eat gold." Frederick was now enabled, by eluding the vigilance of the Austrians, to throw himself upon Dresden, for the purpose of regaining a position indispensable to him on account of its proximity to Bohemia, Silesia, the Mere, and Saxony. His project, however, failed, notwithstanding the terrible bombardment of the city, and he vented his wrath at this discomfiture on the gallant regiment of Bernburg, which he punished for its want of success by stripping it of every token of military glory.
The constant want of ready money for the purpose of recruiting his army, terribly thinned by the incessant warfare, compelled him to circulate a false currency, the English subsidies no longer covering the expenses of the war, and his own territory being occupied by the enemy. Saxony consequently suffered, and was, owing to this necessity, completely drained, the town council at Leipsic being, for instance, shut up in the depth of winter without bedding, light, or firing, until it had voted a contribution of eight tons of gold; the finest forests were cut down and sold, etc.
Berlin meanwhile fell into the hands of the Russians, who, on this occasion, behaved with humanity. General Todleben even ordered his men to fire upon the allied troop, consisting of fifteen thousand Austrians, under Lacy and Brentano, for attempting to infringe the terms of capitulation by plundering the city. The Saxons destroyed the château of Charlottenburg and the superb collection of antiques contained in it, an irreparable loss to art, in revenge for the destruction of the palaces of Bruhl by Frederick. No other treasures of art were carried away or destroyed either by Frederick in Dresden or by his opponents in Berlin. This campaign offered but a single pleasing feature: the unexpected relief of Kolberg, who was hard pushed by the Russians in Pomerania, by the Prussian hussars under General Werner.
Misfortune continued to pursue the King throughout the campaign of 1760. Fouquet, one of his favorites, was, with eight thousand men, surprised and taken prisoner by Laudon in the Giant Mountains near Landshut; the mountain country was cruelly laid waste. The important fortress of Glatz fell, and Breslau was besieged. This city was defended by General Tauenzien, a man of great intrepidity. The celebrated Lessing was at that time his secretary. With merely three thousand Prussians he undertook the defence of the extensive city, within whose walls were nineteen thousand Austrian prisoners.
He maintained himself until relieved by Frederick. The King hastened to defend Silesia, for which Soltikoff's procrastination allowed him ample opportunity. Daun had, it is true, succeeded in forming a junction with Laudon at Liegnitz, but their camps were separate, and the two generals were on bad terms. Frederick advanced close in their vicinity. An attempt made by Laudon, during the night of August 15th, to repeat the disaster of Hochkirch, was frustrated by the secret advance of the King to his rencounter, and a brilliant victory was gained by the Prussians over their most dangerous antagonist. The sound of the artillery being carried by the wind in a contrary direction, the news of the action and of its disastrous termination reached Daun simultaneously; at all events, he put this circumstance forward as an excuse, on being, not groundlessly, suspected of having betrayed Laudon from a motive of jealousy. He retreated into Saxony. The regiment of Bernburg had greatly distinguished itself in this engagement, and on its termination an old subaltern officer stepped forward and demanded from the King the restoration of its military badges, to which Frederick gratefully acceded.
Scarcely, however, were Breslau relieved and Silesia delivered from Laudon's wild hordes than his rear was again threatened by Daun, who had fallen back upon the united Imperial army in Saxony and threatened to form a junction with the Russians then stationed in his vicinity in the Mere. Frederick, conscious of his utter inability to make head against this overwhelming force, determined, at all risks, to bring Daun and the Imperial army to a decisive engagement before their junction with the Russians, and, accordingly, attacked them at Torgau. Before the commencement of the action he earnestly addressed his officers and solemnly prepared for death. Daun, naturally as anxious to evade an engagement as Frederick was to hazard one, had, as at Collin, taken up an extremely strong position, and received the Prussians with a well-sustained fire.
A terrible havoc ensued; the battle raged with various fortune during the whole of the day, and, notwithstanding the most heroic attempts, the position was still uncarried at fall of night. The confusion had become so general that Prussian fought with Prussian, whole regiments had disbanded, and the King was wounded when Zieten, the gallant hussar general, who had during the night cut his way through the Austrians, who were in an equal state of disorder and had taken the heights, rushed into his presence. Zieten had often excited the King's ridicule by his practice of brandishing his sabre over his head in sign of the cross, as an invocation for the aid of Heaven before making battle; but now, deeply moved, he embraced his deliverer, whose work was seen at break of day. The Austrians were in full retreat. This bloody action, by which the Prussian monarchy was saved, took place on November 3, 1760.
