As he was upon the point of setting off, seven Austrian deserters came in and reported that General Neipperg’s 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. It was soon ascertained that the main body of the Austrian army was fifteen miles to the southwest, at Freudenthal, pressing on toward Neisse. General Neipperg, without the slightest suspicion that Frederick was any where in his vicinity, had sent aside a reconnoitring party of skirmishers to ascertain if there were any Prussians at Jagerndorf. General Neipperg, at Freudenthal, was as near Neisse as Frederick was at Jagerndorf. There was not a moment to be lost. General Neipperg was moving resolutely forward with a cloud of skirmishers in the advance and on his wings. With the utmost exertions Frederick immediately rendezvoused all his remote posts, destroying such stores as could not hastily be removed, and by a forced march of twenty-five miles in one day reached Neustadt. General Neipperg was marching by a parallel road about twenty miles west of that which the Prussians traversed. At Neustadt the king was still twenty miles from Neisse. With the delay of but a few hours, that he might assemble all the Prussian bands from the posts in that neighborhood, the king again resumed his march. He had no longer any hope of continuing the siege of Neisse. His only aim was to concentrate all his scattered forces, which had been spread over an area of nearly two thousand square miles, and, upon some well-selected field, to trust to the uncertain issues of a general battle. There was no choice left for him between this course and an ignominious retreat.
