ONE:The Emperor Joseph had been embarrassed in his ambitious plans by the conscientious scruples of his mother. He now entered into a secret alliance with the Czarina Catharine, by which he engaged to assist her in her advance to Constantinople, while she, in her turn, was to aid him in his encroachments and annexations to establish an empire in the West as magnificent as the czarina hoped to establish in the East.As he was upon the point of setting off, seven Austrian deserters came in and reported that General Neippergs full army was advancing at but a few miles distance. Even as they were giving their report, sounds of musketry and cannon announced that the Prussian outposts were assailed by the advance-guard of the foe. The peril of Frederick was great. Had Neipperg known the prize within his reach, the escape of the Prussian king would have been almost impossible. Frederick had but three or four thousand men with him at Jagerndorf, and only three pieces of artillery, with forty rounds of ammunition. Bands of Austrian cavalry on fleet horses were swarming all around him. Seldom, in the whole course of his life, had Frederick been placed in a more critical position.
