Had the Silesian question been merely a question between Frederic and Maria Theresa, it would be impossible to acquit the Prussian King of gross perfidy. But when we consider the effects which his policy produced, and could not fail to produce, on the whole community of civilised nations, we are compelled to pronounce a condemnation still more severe. Till he began the war, it seemed possible, even probable, that the peace of the world would be preserved. The plunder of the great Austrian heritage was indeed a strong temptation; and in more than one cabinet ambitious schemes were already meditated. But the treaties by which the Pragmatic Sanction had been guaranteed were express and recent. To throw all Europe into confusion for a purpose clearly unjust, was no light matter. England was true to her engagements. The voice of Fleury had always been for peace. He had a conscience. He was now in extreme old age, and was unwilling, after a life which, when his situation was considered, must be pronounced singularly pure, to carry the fresh stain of a great crime before the tribunal of his God. Even the vain and unprincipled Belle-Isle, whose whole life was one wild day-dream of conquest and spoliation, felt that France, bound as she was by solemn stipulations, could not, without disgrace, make a direct attack on the Austrian dominions. Charles, Elector of Bavaria, pretended that he had a right to a large part of the inheritance which the Pragmatic Sanction gave to the Queen of Hungary; but he was not sufficiently powerful to move without support. It might, therefore, not unreasonably be expected that, after a short period of restlessness, all the potentates of Christendom would acquiesce in the arrangements made by the late Emperor. But the selfish rapacity of the King of Prussia gave the signal to his neighbours. His example quieted their sense of shame. His success led them to underrate the difficulty of dismembering the Austrian monarchy. The whole world sprang to arms. On the head of Frederic is all the blood which was shed in a war which raged during many years and in every quarter of the globe, the blood of the column of Fontenoy, the blood of the mountaineers who were slaughtered at Culloden. The evils produced by his wickedness were felt in lands where the name of Prussia was unknown; and, in order that he might rob a neighbour whom he had promised to defend, black men fought on the coast of Coromandel, and red men scalped each other by the Great Lakes of North America.

Silesia had been occupied without a battle; but the Austrian troops were advancing to the relief of the fortresses which still held out. In the spring Frederic rejoined his army. He had seen little of war, and had never commanded any great body of men in the field. It is not, therefore, strange that his first military operations showed little of that skill which, at a later period, was the admiration of Europe. What connoisseurs say of some pictures painted by Raphael in his youth, may be said of this campaign. It was in Frederic’s early bad manner. Fortunately for him, the generals to whom he was opposed were men of small capacity. The discipline of his own troops, particularly of the infantry, was unequalled in that age; and some able and experienced officers were at hand to assist him with their advice. Of these, the most distinguished was Field-Marshal Schwerin, a brave adventurer of Pomeranian extraction, who had served half the governments in Europe, had borne the commissions of the States-General of Holland and of the Duke of Mecklenburg, had fought under Marlborough at Blenheim, and had been with Charles the Twelfth at Bender.

Frederic’s first battle was fought at Molwitz; and never did the career of a great commander open in a more inauspicious manner. His army was victorious. Not only, however, did he not establish his title to the character of an able general; but he was so unfortunate as to make it doubtful whether he possessed the vulgar courage of a soldier. The cavalry, which he commanded in person, was put to flight. Unaccustomed to the tumult and carnage of a field of battle, he lost his self-possession, and listened too readily to those who urged him to save himself. His English grey carried him many miles from the field, while Schwerin, though wounded in two places, manfully upheld the day. The skill of the old Field-Marshal and the steadiness of the Prussian battalions prevailed; and the Austrian army was driven from the field with the loss of eight thousand men.

The news was carried late at night to a mill in which the King had taken shelter. It gave him a bitter pang. He was successful; but he owed his success to dispositions which others had made, and to the valour of men who had fought while he was flying. So unpromising was the first appearance of the greatest warrior of that age.

The battle of Molwitz was the signal for a general explosion throughout Europe. Bavaria took up arms. France, not yet declaring herself a principal in the war, took part in it as an ally of Bavaria. The two great statesmen to whom mankind had owed many years of tranquillity, disappeared about this time from the scene, but not till they had both been guilty of the weakness of sacrificing their sense of justice and their love of peace to the vain hope of preserving their power. Fleury, sinking under age and infirmity, was borne down by the impetuosity of Belle-Isle. Walpole retired from the service of his ungrateful country to his woods and paintings at Houghton; and his power devolved on the daring and eccentric Carteret. As were the ministers, so were the nations. Thirty years during which Europe had, with few interruptions, enjoyed repose, had prepared the public mind for great military efforts. A new generation had grown up, which could not remember the siege of Turin or the slaughter of Malplaquet; which knew war by nothing but its trophies; and which, while it looked with pride on the tapestries at Blenheim, or the statue in the Place of Victories, little thought by what privations, by what waste of private fortunes, by how many bitter tears, conquests must be purchased.

For a time fortune seemed adverse to the Queen of Hungary. Frederic invaded Moravia. The French and Bavarians penetrated into Bohemia, and were there joined by the Saxons. Prague was taken. The Elector of Bavaria was raised by the suffrages of his colleagues to the Imperial throne, a throne which the practice of centuries had almost entitled the House of Austria to regard as a hereditary possession.

Yet was the spirit of the haughty daughter of the Caesars unbroken. Hungary was still hers by an unquestionable title; and although her ancestors had found Hungary the most mutinous of all their kingdoms, she resolved to trust herself to the fidelity of a people, rude indeed, turbulent, and impatient of oppression, but brave, generous, and simple-hearted. In the midst of distress and peril she had given birth to a son, afterwards the Emperor Joseph the Second. Scarcely had she arisen from her couch, when she hastened to Presburg. There, in the sight of an innumerable multitude, she was crowned with the crown and robed with the robe of St. Stephen. No spectator could restrain his tears when the beautiful young mother, still weak from child-bearing, rode, after the fashion of her fathers, up the Mount of Defiance, unsheathed the ancient sword of state, shook it towards north and south, east and west, and, with a glow on her pale face, challenged the four corners of the world to dispute her rights and those of her boy. At the first sitting of the Diet she appeared clad in deep mourning for her father, and in pathetic and dignified words implored her people to support her just cause. Magnates and deputies sprang up, half drew their sabres, and with eager voices vowed to stand by her with their lives and fortunes. Till then, her firmness had never once forsaken her before the public eye; but at that shout she sank down upon her throne, and wept aloud. Still more touching was the sight when, a few days later, she came again before the Estates of her realm, and held up before them the little Archduke in her arms. Then it was that the enthusiasm of Hungary broke forth into that war-cry which soon resounded throughout Europe, “Let us die for our King, Maria Theresa!”

In the meantime, Frederic was meditating a change of policy. He had no wish to raise France to supreme power on the Continent, at the expense of the House of Hapsburg. His first object was to rob the Queen of Hungary. His second object was that, if possible, nobody should rob her but himself. He had entered into engagements with the powers leagued against Austria; but these engagements were in his estimation of no more force than the guarantee formerly given to the Pragmatic Sanction. His plan now was to secure his share of the plunder by betraying his accomplices. Maria Theresa was little inclined to listen to any such compromise; but the English Government represented to her so strongly the necessity of buying off Frederic, that she agreed to negotiate. The negotiation would not, however, have ended in a treaty, had not the arms of Frederic been crowned with a second victory. Prince Charles of Lorraine, brother-in-law to Maria Theresa, a bold and active, though unfortunate general, gave battle to the Prussians at Chotusitz, and was defeated. The King was still only a learner of the military art. He acknowledged, at a later period, that his success on this occasion was to be attributed, not at all to his own generalship, but solely to the valour and steadiness of his troops. He completely effaced, however, by his personal courage and energy, the stain which Molwitz had left on his reputation.

A peace, concluded under the English mediation, was the fruit of this battle. Maria Theresa ceded Silesia: Frederic abandoned his allies: Saxony followed his example; and the Queen was left at liberty to turn her whole force against France and Bavaria. She was everywhere triumphant. The French were compelled to evacuate Bohemia, and with difficulty effected their escape. The whole line of their retreat might be tracked by the corpses of thousands who had died of cold, fatigue, and hunger. Many of those who reached their country carried with them the seeds of death. Bavaria was overrun by bands of ferocious warriors from that bloody debatable land which lies on the frontier between Christendom and Islam. The terrible names of the Pandoor, the Croat, and the Hussar, then first became familiar to Western Europe. The unfortunate Charles of Bavaria, vanquished by Austria, betrayed by Prussia, driven from his hereditary states, and neglected by his allies, was hurried by shame and remorse to an untimely end. An English army appeared in the heart of Germany, and defeated the French at Dettingen. The Austrian captains already began to talk of completing the work of Marlborough and Eugene, and of compelling France to relinquish Alsace and the three Bishoprics.

The Court of Versailles, in this peril, looked to Frederic for help. He had been guilty of two great treasons: perhaps he might be induced to commit a third. The Duchess of Chateauroux then held the chief influence over the feeble Lewis. She, determined to send an agent to Berlin; and Voltaire was selected for the mission. He eagerly undertook the task; for, while his literary fame filled all Europe, he was troubled with a childish craving for political distinction. He was vain, and not without reason, of his address, and of his insinuating eloquence: and he flattered himself that he possessed boundless influence over the King of Prussia. The truth was that he knew, as yet, only one corner of Frederic’s character. He was well acquainted with all the petty vanities and affectations of the poetaster; but was not aware that these foibles were united with all the talents and vices which lead to success in active life, and that the unlucky versifier who pestered him with reams of middling Alexandrines, was the most vigilant, suspicious, and severe of politicians.

Voltaire was received with every mark of respect and friendship, was lodged in the palace, and had a seat daily at the royal table. The negotiation was of an extraordinary description. Nothing can be conceived more whimsical than the conferences which took place between the first literary man and the first practical man of the age, whom a strange weakness had induced to exchange their parts. The great poet would talk of nothing but treaties and guarantees, and the great King of nothing but metaphors and rhymes. On one occasion Voltaire put into his Majesty’s hands a paper on the state of Europe, and received it back with verses scrawled on the margin. In secret they both laughed at each other. Voltaire did not spare the King’s poems; and the King has left on record his opinion of Voltaire’s diplomacy. “He had no credentials,” says Frederic, “and the whole mission was a joke, a mere farce.”

But what the influence of Voltaire could not effect, the rapid progress of the Austrian arms effected. If it should be in the power of Maria Theresa and George the Second to dictate terms of peace to France, what chance was there that Prussia would long retain Silesia? Frederic’s conscience told him that he had acted perfidiously and inhumanly towards the Queen of Hungary. That her resentment was strong she had given ample proof; and of her respect for treaties he judged by his own. Guarantees, he said, were mere filigree, pretty to look at, but too brittle to bear the slightest pressure. He thought it his safest course to ally himself closely to France, and again to attack the Empress Queen. Accordingly, in the autumn of 1744, without notice, without any decent pretext, he recommenced hostilities, marched through the electorate of Saxony without troubling himself about the permission of the Elector, invaded Bohemia, took Prague, and even menaced Vienna.

It was now that, for the first time, he experienced the inconstancy of fortune. An Austrian army under Charles of Lorraine threatened his communications with Silesia. Saxony was all in arms behind him. He found it necessary to save himself by a retreat. He afterwards owned that his failure was the natural effect of his own blunders. No general, he said, had ever committed greater faults. It must be added, that to the reverses of this campaign he always ascribed his subsequent successes. It was in the midst of difficulty and disgrace that he caught the first clear glimpse of the principles of the military art.

The memorable year 1745 followed. The war raged by sea and land, in Italy, in Germany, and in Flanders; and even England, after many years of profound internal quiet, saw, for the last time, hostile armies set in battle array against each other. This year is memorable in the life of Frederic, as the date at which his noviciate in the art of war may be said to have terminated. There have been great captains whose precocious and self-taught military skill resembled intuition. Conde, Clive, and Napoleon are examples. But Frederic was not one of these brilliant portents. His proficiency in military science was simply the proficiency which a man of vigorous faculties makes in any science to which he applies his mind with earnestness and industry. It was at Hohenfriedberg that he first proved how much he had profited by his errors, and by their consequences. His victory on that day was chiefly due to his skilful dispositions, and convinced Europe that the prince who, a few years before, had stood aghast in the rout of Molwitz, had attained in the military art a mastery equalled by none of his contemporaries, or equalled by Saxe alone. The victory of Hohenfriedberg was speedily followed by that of Sorr.

In the meantime, the arms of France had been victorious in the Low Countries. Frederic had no longer reason to fear that Maria Theresa would be able to give law to Europe, and he began to meditate a fourth breach of his engagements. The Court of Versailles was alarmed and mortified. A letter of earnest expostulation, in the handwriting of Lewis, was sent to Berlin; but in vain. In the autumn of 1745, Frederic made Peace with England, and, before the close of the year, with Austria also. The pretensions of Charles of Bavaria could present no obstacle to an accommodation. That unhappy Prince was no more; and Francis of Lorraine, the husband of Maria Theresa, was raised, with the general assent of the Germanic body, to the Imperial throne.

Prussia was again at peace; but the European war lasted till, in the year 1748, it was terminated by the treaty of Aix-la Chapelle. Of all the powers that had taken part in it, the only gainer was Frederic. Not only had he added to his patrimony the fine province of Silesia: he had, by his unprincipled dexterity, succeeded so well in alternately depressing the scale of Austria and that of France, that he was generally regarded as holding the balance of Europe, a high dignity for one who ranked lowest among kings, and whose great-grandfather had been no more than a Margrave. By the public, the King of Prussia was considered as a politician destitute alike of morality and decency, insatiably rapacious, and shamelessly false; nor was the public much in the wrong. He was at the same time, allowed to be a man of parts, a rising general, a shrewd negotiator and administrator. Those qualities wherein he surpassed all mankind, were as yet unknown to others or to himself; for they were qualities which shine out only on a dark ground. His career had hitherto, with little interruption, been prosperous; and it was only in adversity, in adversity which seemed without hope or resource, in adversity which would have overwhelmed even men celebrated for strength of mind, that his real greatness could be shown.
