The emperor, invested with the imperial crown, hastened to Vienna, and, with unexpected energy, entered upon the administration of the complicated interests of his widespread realms. After passing a few weeks in Vienna, he repaired to Prague, where, in May, he was, with much pomp, crowned King of Hungary. He then returned to Vienna, and prepared to press with new vigor the war of the Spanish succession.
Louis XIV. was now suffering the earthly retribution for his ill-spent life. The finances of the realm were in a state of hopeless embarrassment; famine was filling the kingdom with misery; his armies were everywhere defeated; the imprecations of a beggared people were rising around his throne; his palace was the scene of incessant feuds and intrigues. His children were dead; he was old, infirm, sick, the victim of insupportable melancholy—utterly weary of life, and yet awfully afraid to die. France, in the person of Louis XIV., who could justly say, "I am the State," was humbled.
The accession of Charles to the throne of the empire, and to that of Austria, Hungary and Bohemia, while at the same time he claimed sovereignty over the vast realms of the Spanish kingdom, invested him with such enormous power, that England, which had combined Europe against the colossal growth of France, having humbled that power, was disposed to form a combination against Austria. There was in consequence an immediate relaxation of hostilities just at the time when the French batteries on the frontiers were battered down, and when the allied army had apparently an unobstructed way opened to the gates of Paris. In this state of affairs the British ministry pressed negotiations for peace. The preliminaries were settled in London on the 8th of October, 1711. By this treaty Louis XIV. agreed to make such a change in the law of hereditary descent, as to render it impossible for any king to wear at the same time the crowns of France and of Spain, and made various other important concessions.
Charles, whose ambition was roused by his sudden and unexpected elevation, exerted all his energies to thwart the progress of negotiations, and bitterly complained that the allies were dishonorably deserting the cause which they had espoused. The emperor dispatched circular letters to all the courts of Europe, and sent Prince Eugene as a special ambassador to London, to influence Queen Anne, if possible, to persevere in the grand alliance. But he was entirely unsuccessful. The Duke of Marlborough was disgraced, and dismissed from office. The peace party rendered Eugene so unpopular that he was insulted in the streets of London. The Austrian party in England was utterly defeated, and a congress was appointed to meet at Utrecht to settle the terms of peace. But Charles was now so powerful that he resolved to prosecute the war even though abandoned by England. He accordingly sent an ambassador to Utrecht to embarrass the proceedings as much as possible, and, in case the grand alliance should be broken up, to secure as many powers as possible in fidelity to Austria.
The States of the Netherlands were still warmly with Austria, as they dreaded so formidable a power as France directly upon their frontier. The other minor powers of the alliance were also rather inclined to remain with Austria. The war continued while the terms of peace were under discussion. England, however, entered into a private understanding with France, and the Duke of Ormond, who had succeeded Marlborough, received secret orders not to take part in any battle or siege. The developments, upon fields of battle, of this dishonorable arrangement, caused great indignation on the part of the allies. The British forces withdrew, and the French armies, taking advantage of the great embarrassments thus caused, were again gaining the ascendency. Portugal soon followed the example of England and abandoned the alliance. The Duke of Savoy was the next to leave. The alliance was evidently crumbling to pieces, and on the 11th of April, 1713, all the belligerents, excepting the emperor, signed the treaty of peace. Philip of Spain also acceded to the same articles.
Charles was very indignant in being thus abandoned; and unduly estimating his strength, resolved alone, with the resources which the empire afforded him, to prosecute the war against France and Spain. Having nothing to fear from a Spanish invasion, he for a time relinquished his attempts upon Spain, and concentrating his armies upon the Rhine, prepared for a desperate onset upon France. For two years the war raged between Austria and France with war's usual vicissitudes of defeat and victory on either side. It was soon evident that the combatants were too equally matched for either party to hope to gain any decisive advantage over the other. On the 7th of September, 1714, France and Austria agreed to sheathe the sword. The war had raged for fourteen years, with an expenditure of blood and treasure, and an accumulation of misery which never can be gauged. Every party had lost fourfold more than it had gained. "A war," says Marshal Villers, "which had desolated the greater part of Europe, was concluded almost on the very terms which might have been procured at the commencement of hostilities."
By this treaty of peace, which was signed at Baden, in Switzerland, the States of the Netherlands were left in the hands of Austria; and also the Italian States of Naples, Milan, Mantua and Sardinia. The thunders of artillery had hardly ceased to reverberate over the marshes of Holland and along the banks of the Rhine, ere the "blast of war's loud organ" and the tramp of charging squadrons were heard rising anew from the distant mountains of Sclavonia. The Turks, in violation of their treaty of peace, were again on the march, ascending the Danube along its southern banks, through the defiles of the Sclavonian mountains. In a motley mass of one hundred and fifty thousand men they had passed Belgrade, crossed the Save, and were approaching Peterwarden.
Eugene was instantly dispatched with an efficient, compact army, disciplined by twelve years of warfare, to resist the Moslem invaders. The hostile battalions met at Karlowitz, but a few miles from Peterwarden, on the 5th of August, 1716. The tempest blazed with terrific fury for a few hours, when the Turkish host turned and fled. Thirty thousand of their number, including the grand vizier who led the host, were left dead upon the field. In their utter discomfiture they abandoned two hundred and fifty pieces of heavy artillery, and baggage, tents and military stores to an immense amount. Fifty Turkish banners embellished the camp of the victors.
And now Eugene led his triumphant troops, sixty thousand in number, down the river to lay siege to Belgrade. This fortress, which the labor of ages had strengthened, was garrisoned by thirty thousand troops, and was deemed almost impregnable. Eugene invested the place and commenced the slow and tedious operations of a siege. The sultan immediately dispatched an army of two hundred thousand men to the relief of his beleaguered fortress. The Turks, arriving at the scene of action, did not venture an assault upon their intrenched foes, but intrenched themselves on heights, outside of the besieging camp, in a semicircle extending from the Danube to the Save. They thus shut up the besiegers in the miasmatic marshes which surrounded the city, cut off their supplies of provisions, and from their advancing batteries threw shot into the Austrian camp. "A man," said Napoleon, "is not a soldier." The Turks had two hundred thousand men in their camp, raw recruits. Eugene had sixty thousand veteran soldiers. He decided to drive off the Turks who annoyed him. It was necessary for him to detach twenty thousand to hold in check the garrison of Belgrade, who might sally to the relief of their companions. This left him but forty thousand troops with whom to assail two hundred thousand strongly intrenched. He did not hesitate in the undertaking.
