Lewis XV. who never had seen an army, was now for putting himself at the head of his troops, and determined to make his first campaign in Flanders. On his arrival, Courtray surrendered; and soon after Menin followed its example. The King himself, to the great encouragement of the soldiery, used to be present at the works.

This first campaign of the King’s having been much talked of in France; on the peace, I asked his Majesty, whether he had found in himself a fixed inclination for war. He at first eluded answering me, and talked in general terms; but a year after, in one of those moments of confidence, when the heart lays itself open in the arms of friendship, he told me it would have been his reigning passion; and that, without the recent example of his great-grand-father, and Cardinal Fleury’s earnest councils to him, he should totally have given himself up to war; but that the affection due to his people had got the better of his passion. Happy government, when the Monarch sacrifices his propensions to the welfare of his subjects!

Lewis was obliged to quit his first conquests, and fly to the assistance of Alsace, Prince Charles having passed the Rhine to invade several of the French provinces; but upon the King’s approach at the head of his army, the prince repassed the Rhine.

All the advantages which France had gained in Flanders did not much improve its situation. The Queen of Hungary’s alliance with England, Holland, Sardinia, and Saxony was too great a counterpoize. The king of Prussia himself made a convention with Great Britain, but had not included in his agreement that the house of Austria should become so powerful. In treaties between Sovereigns, it is always understood, that the party in favour of whom a neutrality is observed, shall not increase his forces beyond a certain relative proportion: now the house of Brandenburgh has more to fear from that of Austria than from any other in Europe; so he kept himself a mere spectator of the war, whilst the losses of France and the emperor were inconsiderable; but on the queen’s making a rapid progress, he armed to stop her career. I have since frequently asked the Marshal de Noailles, one of the greatest politicians in France, why Sovereign Princes make no scruple to commit these breaches of faith, which in common life are reckoned intolerable vices? His constant answer was, that these infractions were necessary, and that Europe even owed its safety to them: were it not for such failures, the universal commonwealth would soon be made subject to one single prince; and this he might compass, only by once bringing the others to stand neuter.

The King of Prussia’s first step, after his new alliance with France, was, to march with a powerful army towards Prague. Whilst all France was rejoicing at Frederic’s successes, advice came that the King was taken ill at Metz, and the symptoms were grown very dangerous: this caused a general affliction; I remember every body was in tears. These cordial marks of affection are a higher praise, and express his character better than all the flattering strokes with which writers will disfigure his history. I have talked with many who were present at the death of Lewis XIV. and according to them, not a tear was shed in France. Nobody was afflicted with the news; and his death was quite forgot before he was buried; heroism being less esteemed than goodness; and Lewis XV. is the best Prince that ever sat on a throne.

The beloved Monarch recovered, and then the nation’s joy exceeded its former consternation. He laid siege to Friburg in Brisgau, and razed its fortifications, as he had demolished those of other places which had yielded to his arms: A policy, which, perhaps, may prevent many wars hereafter.

M. de Maurepas was saying one day to me on this head, that the Turks and Persians have scarce any fortified places, and that was the reason of their seldom making war on one another. I have since heard, that most of our wars in Europe were owing to this; that states confided too much in bastions and citadels, which hindered negociations from taking effect. If so, the famous Vauban, whose genius is so often extolled, must have done a great deal of mischief to France.

In the mean time, the King of Prussia, who, by arming in favour of France, had changed all the German systems, decamped from Prague; his army fled before that of Prince Charles, who, repassing the Rhine in the sight of the French, crossed the Elbe to attack the Prussians. I never could come at a certain knowledge of this Prince Charles, who directed most of the plans of this war; some speaking so very well of him, and others so very ill, that I have not been able to form any settled judgment of his character.

Marshal Noailles, who knows men, has told me that this Prince wanted neither talents nor genius, but that the goodness of his heart frustrated the qualities of his mind. Instead of having a will of his own, added he, he suffers himself to be directed by those about him; and these are not always the best head-pieces in the world. For instance, continued he, Prince Charles is now at Brussels as Governor of the Low Countries; but there is a German about him, who turns and winds him at his pleasure, and his pleasure is not always what should be.

The Austrian power, which had been weakened by the king of Prussia’s joining with France, now received an increase by an alliance with the Elector of Saxony, King of Poland. This Monarch changed measures for the same reason which had induced the King of Prussia to change.
