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 valor 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.
