The King of France, alarmed by the progress which the Austrians were making in his own territories, ordered thirty thousand troops, from the army in the Netherlands, to be dispatched to the protection of Alsace. Again the tide was turning against Maria Theresa. She had become so arrogant and exacting, that she had excited the displeasure of nearly all the empire. She persistently refused to acknowledge the emperor, who, beyond all dispute, was legally elected; she treated the diet contemptuously; she did not disguise her determination to hold Bavaria by the right of conquest, and to annex it to Austria; she had compelled the Bavarians to take the oath of allegiance to her; she was avowedly meditating gigantic projects in the conquest of France and Italy; and it was very evident that she was maturing her plans for the reconquest of Silesia. Such inordinate ambition alarmed all the neighboring courts. Frederic of Prussia was particularly alarmed lest he should lose Silesia. With his accustomed energy he again drew his sword against the queen, and became the soul of a new confederacy which combined many of the princes of the empire whom the haughty queen had treated with so much indignity. In this new league, formed by Frederic, the Elector Palatine and the King of Sweden were brought into the field against Maria Theresa. All this was effected with the utmost secrecy, and the queen had no intimation of her danger until the troops were in motion. Frederic published a manifesto in which he declared that he took up arms "to restore to the German empire its liberty, to the emperor his dignity, and to Europe repose."
With his strong army he burst into Bohemia, now drained of its troops to meet the war in the Netherlands and on the Rhine. With a lion's tread, brushing all opposition away, he advanced to Prague. The capital was compelled to surrender, and the garrison of fifteen thousand troops became prisoners of war. Nearly all the fortresses of the kingdom fell into his hands. Establishing garrisons at Tabor, Budweiss, Frauenberg, and other important posts, he then made an irruption into Bavaria, scattered the Austrian troops in all directions, entered Munich in triumph, and reinstated the emperor in the possession of his capital and his duchy. Such are the fortunes of war. The queen heard these tidings of accumulated disaster in dismay. In a few weeks of a summer's campaign, when she supposed that Europe was almost a suppliant at her feet, she found herself deprived of the Netherlands, of the whole kingdom of Bohemia, the brightest jewel in her crown, and of the electorate of Bavaria.
But the resolution and energy of the queen remained indomitable. Maria Theresa and Frederic were fairly pitted against each other. It was Greek meeting Greek. The queen immediately recalled the army from Alsace, and in person repaired to Presburg, where she summoned a diet of the Hungarian nobles. In accordance with an ancient custom, a blood-red flag waved from all the castles in the kingdom, summoning the people to a levy en masse, or, as it was then called, to a general insurrection. An army of nearly eighty thousand men was almost instantly raised. A cotemporary historian, speaking of this event, says:
"This amazing unanimity of a people so divided amongst themselves as the Hungarians, especially in point of religion, could only be effected by the address of Maria Theresa, who seemed to possess one part of the character of Elizabeth of England, that of making every man about her a hero."
Prince Charles re-crossed the Rhine, and, by a vigorous march through Suabia, returned to Bohemia. By surprise, with a vastly superior force, he assailed the fortresses garrisoned by the Prussian troops, gradually took one after another, and ere long drove the Prussians, with vast slaughter, out of the whole kingdom. Though disaster, in this campaign, followed the banners of Maria Theresa in the Netherlands and in Italy, she forgot those reverses in exultation at the discomfiture of her great rival Frederic. She had recovered Bohemia, and was now sanguine that she soon would regain Silesia, the loss of which province ever weighed heavily upon her heart. But in her character woman's weakness was allied with woman's determination. She imagined that she could rouse the chivalry of her allies as easily as that of the Hungarian barons, and that foreign courts, forgetful of their own grasping ambition, would place themselves as pliant instruments in her hands.
In this posture of affairs, the hand of Providence was again interposed, in an event which removed from the path of the queen a serious obstacle, and opened to her aspiring mind new visions of grandeur. The Emperor Charles VII., an amiable man, of moderate abilities, was quite crushed in spirit by the calamities accumulating upon him. Though he had regained his capital, he was in hourly peril of being driven from it again. Anguish so preyed upon his mind, that, pale and wan, he was thrown upon a sick bed. While in this state he was very injudiciously informed of a great defeat which his troops had encountered. It was a death-blow to the emperor. He moaned, turned over in his bed, and died, on the 20th of January, 1745.
The imperial crown was thus thrown down among the combatants, and a scramble ensued for its possession such as Europe had never witnessed before. Every court was agitated, and the combinations of intrigue were as innumerable as were the aspirants for the crown. The spring of 1745 opened with clouds of war darkening every quarter of the horizon. England opened the campaign in Italy and the Netherlands, her whole object now being to humble France. Maria Theresa remained uncompromising in her disposition to relinquish nothing and to grasp every thing. The cabinet of England, with far higher views of policy, were anxious to detach some of the numerous foes combined against Austria; but it was almost impossible to induce the queen to make the slightest abatement of her desires. She had set her heart upon annexing all of Bavaria to her realms. That immense duchy, now a kingdom, was about the size of the State of South Carolina, containing over thirty thousand square miles. Its population amounted to about four millions. The death of the Emperor Charles VII., who was Elector of Bavaria, transmitted the sovereignty of this realm to his son, Maximilian Joseph.
Maximilian was anxious to withdraw from the strife. He agreed to renounce all claim to the Austrian succession, to acknowledge the validity of the queen's title, to dismiss the auxiliary troops, and to give his electoral vote to the Duke of Lorraine for emperor. But so eager was the queen to grasp the Bavarian dominions, that it was with the utmost difficulty that England could induce her to accede even to these terms.
It is humiliating to record the readiness of these old monarchies to sell themselves and their armies to any cause which would pay the price demanded. For seven hundred and fifty thousand dollars England purchased the alliance of Poland, and her army of thirty thousand men. Before the treaty was formally ratified, the Emperor Charles VII. died, and there were indications that Bavaria would withdraw from the French alliance. This alarmed the French ministry, and they immediately offered Poland a larger sum than England had proffered, to send her army to the French camp. The bargain was on the point of being settled, when England and Austria again rushed in, and whispered in the ear of Augustus that they intended to chastise the King of Prussia thoroughly, and that if Poland would help them, Poland should be rewarded with generous slices of the Prussian territory. This was a resistless bribe, and the Polish banners were borne in the train of the Austrian alliance.
The Duke of Lorraine was much annoyed by the imperial assumption of his wife. She was anxious to secure for him the crown of Germany, as adding to her power and grandeur. But Francis was still more anxious to attain that dignity, as his position in the court, as merely the docile subject of his wife, the queen, was exceedingly humiliating. The spring of 1745 found all parties prepared for the renewal of the fight. The drama was opened by the terrible battle of Fontenoy in the Netherlands. On the 11th of May eighty thousand French met the Austrian allied army of fifty thousand. After a few hours of terrific slaughter the allies retreated, leaving the French in possession of the field. In Italy, also, the tide of war set against the queen. The French and Spaniards poured an army of seventy thousand men over the Alps into Italy. The queen, even with the aid of Sardinia, had no force capable of resisting them. The allies swept the country. The King of Sardinia was driven behind the walls of his capital. In this one short campaign Tortona, Placentia, Parma, Pavia, Cazale and Aste were wrested from the Austrians, and the citadels of Alexandria and Milan were blockaded.
