THREE:Whilst Louis lay ill at Metz, France received an unexpected relief. Prince Charles was hastily recalled to cope with Frederick of Prussia, who had now joined France in the counter-league of Frankfort, and burst into the territories of Maria Theresa. He found in Prague a garrison of fifteen thousand men, yet by the 15th of September he had reduced the place, after a ten days' siege. At the same time Marshal Seckendorf, the Imperial general, entered Bavaria, which was defended only by a small force, and quickly reinstated[88] Charles on the throne of Munich. Vienna itself was in the greatest alarm, lest the enemies uniting should pay it a visit. But this danger was averted by the rapid return of Prince Charles of Lorraine from before Strasburg. He had to pass the very front of the French army; nevertheless, he conducted his forces safely and expeditiously to the frontiers of Bohemia, himself hastening to Vienna to consult on the best plan of operations. Maria Theresa again betook herself to her heroic Hungarians, who, at her appeal, once more rushed to her standard; and Frederick, in his turn alarmed, called loudly on the French for their promises of assistance, but called in vain. The French had no desire for another campaign in the heart of Austria. The Prussian invader, therefore, soon found himself menaced on all sides by Austrians, Croatians, and Hungarian troops, who harassed him day and night, cut off his supplies and his forages, and made him glad to retrace his steps in haste.Felipa started back so violently that she struck against the log she had been sitting upon, and lost her balance.
