THREE:The Prussians remained at Lobositz nearly a fortnight, to see if Marshal Browne would again attempt to force the defiles. The Saxon troops, for whose relief the Austrians were advancing, were about thirty miles farther north, on the south, or left408 bank of the Elbe. The news of the repulse of Marshal Browne at Lobositz fell disastrously upon their starving ranks. Maria Theresa was much distressed. She sent a messenger to her Austrian general to relieve the Saxons at whatever cost. A confidential messenger was dispatched through the mountains to the Saxon camp, which he reached in safety. He informed his Polish majesty that Marshal Browne, with a picked force of eight thousand, horse and foot, would march by a circuitous route of sixty miles, so as to approach Pirna from the northeast, where but a small Prussian force was stationed. He would be there without fail on the 11th of August.Under these circumstances, it was evidently impossible for Frederick to retain Silesia unless he could again rally France and other powers to his aid. It was always easy to rouse France against England, its hereditary foe. Thus influenced, Frederick, early in the spring of 1744, entered into a new alliance with France and the Emperor Charles Albert against Maria Theresa. The two marriages which he had so adroitly consummated constrained330 Russia and Sweden to neutrality. While France, by the new treaty, was engaged to assail with the utmost energy, under the leadership of Louis XV. himself, the triumphant Austrian columns upon the Rhine, Frederick, at the head of one hundred thousand troops, was to drive the Austrians out of Bohemia, and reseat Charles Albert upon his hereditary throne. For this service Frederick was to receive from the Bohemian king three important principalities, with their central fortresses near upon the borders of Silesia.
