Frederick declares, in his history, that never were tidings more welcome to him than these. He had embarked in the enterprise for the conquest of Moravia with the allies. He could not, without humiliation, withdraw. But, now that the ally, in whose behalf he assumed to be fighting, had abandoned him, he could, without dishonor, relinquish the field. Leaving the Saxons to themselves, with many bitter words of reproach, he countermanded his order for Silesian re-enforcements, assembled his troops at Wischau, and then, by a rapid march through Olmütz, returned to his strong fortresses in the north. The Saxons were compelled to a precipitate retreat. Their march was long, harassing, and full of suffering, from the severe cold of those latitudes, and from the assaults of the fierce Pandours, every where swarming around. Villages were burned, and maddened men wreaked direful vengeance on each other. Scarcely eight thousand of their number, a frostbitten, starving, emaciate band, reached the borders of Saxony. Curses loud and deep were heaped upon the name of Frederick. His Polish majesty, though naturally good-natured, was greatly exasperated in view of the conduct of the Prussian king in forcing the troops into the severities of such a campaign. Frederick himself was also equally indignant with Augustus for his want of co-operation. The French minister, Valori, met him on his return from these disasters. He says that his look was ferocious and dark; that his laugh was bitter and sardonic; that a vein of suppressed rage, mockery, and contempt pervaded every word he uttered. Frederick withdrew his troops into strong cantonments in the valley of the upper Elbe. This beautiful river takes its rise in romantic chasms, among the ridges and spurs of the Giant Mountains, on the southeastern borders of Silesia. Here the Prussian army was distributed in small towns along a line following the windings of the stream, about forty miles in length. All the troops could be concentrated in forty-eight hours. The encampments faced the south, with the Elbe behind them. At some little distance north of the river, safe from surprise, the magazines were stationed. The mountains of Bohemia rose sublimely in the distant background. In a letter to M. Jordan, under date of Chrudim, May 5th, 1742, Frederick expresses his views of this profitless campaign in the following terms: [Illustration: MAP ILLUSTRATING THE CAMPAIGN IN MORAVIA.] “Moravia, which is a very bad country, could not be held, owing to want of provisions. The town of Brünn could not be taken because the Saxons had no cannon. When you wish to enter a town, you must first make a hole to get in by. Besides, the country has been reduced to such a state that the enemy can not subsist in it, and you will soon see him leave it. There is your little military lesson. I would not have you at a loss what to think of our operations, or what to say, should other people talk of them in your presence.”
