The Duke of Richelieu to the end of his life hated the philosophers as a sect, not for those parts of their system which a good and wise man would have condemned, but for their virtues, for their spirit of free inquiry, and for their hatred of those social abuses of which he was himself the personification. But he, like many of those who thought with him, excepted Voltaire from the list of proscribed writers. He frequently sent flattering letters to Ferney. He did the patriarch the honor to borrow money of him, and even carried this condescending friendship so far as to forget to pay the interest. Voltaire thought that it might be in his power to bring the Duke and the King of Prussia into communication with each other. He wrote earnestly to both; and he so far succeeded that a correspondence between them was commenced.

But it was to very different means that Frederic was to owe his deliverance. At the beginning of November, the net seemed to have closed completely round him. The Russians were in the field, and were spreading devastation through his eastern provinces. Silesia was overrun by the Austrians. A great French army was advancing from the West under the command of Marshal Soubise, a prince of the great Armorican House of Rohan. Berlin itself had been taken and plundered by the Croatians. Such was the situation from which Frederic extricated himself, with dazzling glory, in the short space of thirty days.

He marched first against Soubise. On the fifth of November the armies met at Rosbach. The French were two to one; but they were ill disciplined, and their general was a dunce. The tactics of Frederic, and the well-regulated valor of the Prussian troops, obtained a complete victory. Seven thousand of the invaders were made prisoners. Their guns, their colors, their baggage, fell into the hands of the conquerors. Those who escaped fled as confusedly as a mob scattered by cavalry. Victorious in the West, the King turned his arms towards Silesia. In that quarter everything seemed to be lost. Breslau had fallen; and Charles of Lorraine, with a mighty power, held the whole province. On the fifth of December, exactly one month after the battle of Rosbach, Frederic, with forty thousand men, and Prince Charles, at the head of not less than sixty thousand, met at Leuthen, hard by Breslau. The King, who was, in general, perhaps too much inclined to consider the common soldier as a mere machine, resorted, on this great day, to means resembling those which Bonaparte afterwards employed with such signal success for the purpose of stimulating military enthusiasm. The principal officers were convoked. Frederic addressed them with great force and pathos; and directed them to speak to their men as he had spoken to them. When the armies were set in battle array, the Prussian troops were in a state of fierce excitement; but their excitement showed itself after the fashion of a grave people. The columns advanced to the attack chanting, to the sound of drums and fifes, the rude hymns of the old Saxon Sternholds. They had never fought so well; nor had the genius of their chief ever been so conspicuous. "That battle," said Napoleon, "was a masterpiece. Of itself it is sufficient to entitle Frederic to a place in the first rank among generals." The victory was complete. Twenty-seven thousand Austrians were killed, wounded, or taken; fifty stand of colors, a hundred guns, four thousand wagons, fell into the hands of the Prussians. Breslau opened its gates; Silesia was reconquered; Charles of Lorraine retired to hide his shame and sorrow at Brussels; and Frederic allowed his troops to take some repose in winter quarters, after a campaign to the vicissitudes of which it will be difficult to find any parallel in ancient or modern history.

The King's fame filled all the world. He had, during the last year, maintained a contest, on terms of advantage, against three powers, the weakest of which had more than three times his resources. He had fought four great pitched battles against superior forces. Three of these battles he had gained; and the defeat of Kolin, repaired as it had been, rather raised than lowered his military renown. The victory of Leuthen is, to this day, the proudest on the roll of Prussian fame. Leipsic, indeed, and Waterloo, produced consequences more important to mankind. But the glory of Leipsic must be shared by the Prussians with the Austrians and Russians; and at Waterloo the British infantry bore the burden and heat of the day. The victory of Rosbach was, in a military point of view, less honorable than that of Leuthen; for it was gained over an incapable general and a disorganized army; but the moral effect which it produced was immense. All the preceding triumphs of Frederic had been triumphs over Germans, and could excite no emotions of national pride among the German people. It was impossible that a Hessian or a Hanoverian could feel any patriotic exultation at hearing that Pomeranians had slaughtered Moravians, or that Saxon banners had been hung in the churches of Berlin. Indeed, though the military character of the Germans justly stood high throughout the world, they could boast of no great day which belonged to them as a people; of no Agincourt, of no Bannockburn. Most of their victories had been gained over each other; and their most splendid exploits against foreigners had been achieved under the command of Eugene, who was himself a foreigner. The news of the battle of Rosbach stirred the blood of the whole of the mighty population from the Alps to the Baltic, and from the borders of Courland to those of Lorraine. Westphalia and Lower Saxony had been deluged by a great host of strangers, whose speech was unintelligible, and whose petulant and licentious manners had excited the strongest feelings of disgust and hatred. That great host had been put to flight by a small band of German warriors, led by a prince of German blood on the side of father and mother, and marked by the fair hair and the clear blue eye of Germany. Never since the dissolution of the empire of Charlemagne had the Teutonic race won such a field against the French. The tidings called forth a general burst of delight and pride from the whole of the great family which spoke the various dialects of the ancient language of Arminius. The fame of Frederic began to supply, in some degree, the place of a common government and of a common capital. It became a rallying point for all true Germans, a subject of mutual congratulation to the Bavarian and the Westphalian, to the citizen of Frankfort and the citizen of Nuremberg. Then first it was manifest that the Germans were truly a nation. Then first was discernible that patriotic spirit which, in 1813, achieved the great deliverance of central Europe, and which still guards, and long will guard, against foreign ambition the old freedom of the Rhine.

Nor were the effects produced by that celebrated day merely political. The greatest masters of German poetry and eloquence have admitted that, though the great King neither valued nor understood his native language, though he looked on France as the only seat of taste and philosophy, yet, in his own despite, he did much to emancipate the genius of his countrymen from the foreign yoke; and that, in the act of vanquishing Soubise, he was, unintentionally, rousing the spirit which soon began to question the literary precedence of Boileau and Voltaire. So strangely do events confound all the plans of man. A prince who read only French, who wrote only French, who aspired to rank as a French classic, became, quite unconsciously, the means of liberating half the Continent from the dominion of that French criticism of which he was himself, to the end of his life, a slave. Yet even the enthusiasm of Germany in favor of Frederic hardly equalled the enthusiasm of England. The birthday of our ally was celebrated with as much enthusiasm as that of our own sovereign; and at night the streets of London were in a blaze with illuminations. Portraits of the Hero of Rosbach, with his cocked hat and long pigtail, were in every house. An attentive observer will, at this day, find in the parlors of old-fashioned inns, and in the portfolios of print-sellers, twenty portraits of Frederic for one of George the Second. The sign-painters were everywhere employed in touching up Admiral Vernon into the King of Prussia. This enthusiasm was strong among religious people, and especially among the Methodists, who knew that the French and Austrians were Papists, and supposed Frederic to be the Joshua or Gideon of the Reformed Faith. One of Whitfield's hearers, on the day on which thanks for the battle of Leuthen were returned at the Tabernacle, made the following exquisitely ludicrous entry in a diary, part of which has come down to us: "The Lord stirred up the King of Prussia and his soldiers to pray. They kept three fast days, and spent about an hour praying and singing psalms before they engaged the enemy. Oh, how good it is to pray and fight!" Some young Englishmen of rank proposed to visit Germany as volunteers, for the purpose of learning the art of war under the greatest of commanders. This last proof of British attachment and admiration, Frederic politely but firmly declined. His camp was no place for amateur students of military science. The Prussian discipline was rigorous even to cruelty. The officers, while in the field, were expected to practise an abstemiousness and self-denial such as was hardly surpassed by the most rigid monastic orders. However noble their birth, however high their rank in the service, they were not permitted to eat from anything better than pewter. It was a high crime even in a count and field-marshal to have a single silver spoon among his baggage. Gay young Englishmen of twenty thousand a year, accustomed to liberty and to luxury, would not easily submit to these Spartan restraints. The King could not venture to keep them in order as he kept his own subjects in order. Situated as he was with respect to England, he could not well imprison or shoot refractory Howards and Cavendishes. On the other hand, the example of a few fine gentlemen, attended by chariots and livery servants, eating in plate, and drinking champagne and tokay, was enough to corrupt his whole army. He thought it best to make a stand at first, and civilly refuse to admit such dangerous companions among his troops.

The help of England was bestowed in a manner far more useful and more acceptable. An annual subsidy of near seven hundred thousand pounds enabled the King to add probably more than fifty thousand men to his army. Pitt, now at the height of power and popularity, undertook the task of defending Western Germany against France, and asked Frederic only for the loan of a general. The general selected was Prince Ferdinand of Brunswick, who had attained high distinction in the Prussian service. He was put at the head of an army, partly English, partly Hanoverian, partly composed of mercenaries hired from the petty princes of the empire. He soon vindicated the choice of the two allied courts, and proved himself the second general of the age.

Frederic passed the winter at Breslau, in reading, writing, and preparing for the next campaign. The havoc which the war had made among his troops was rapidly repaired; and in the spring of 1758 he was again ready for the conflict. Prince Ferdinand kept the French in check. The King in the meantime, after attempting against the Austrians some operations which led to no very important result, marched to encounter the Russians, who, slaying, burning, and wasting wherever they turned, had penetrated into the heart of his realm. He gave them battle at Zorndorf, near Frankfort on the Oder. The fight was long and bloody. Quarter was neither given nor taken; for the Germans and Scythians regarded each other with bitter aversion, and the sight of the ravages committed by the half-savage invaders had incensed the King and his army. The Russians were overthrown with great slaughter; and for a few months no further danger was to be apprehended from the East.

A day of thanksgiving was proclaimed by the King, and was celebrated with pride and delight by his people. The rejoicings in England were not less enthusiastic or less sincere. This may be selected as the point of time at which the military glory of Frederic reached the zenith. In the short space of three quarters of a year he had won three great battles over the armies of three mighty and warlike monarchies, France, Austria, and Russia.

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.

Having vanquished the Russians, he hastened into Saxony to oppose the troops of the Empress Queen, commanded by Daun, the most cautious, and Laudohn, 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 vigor of the other seem 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 checkered and eventful life.
