On the 15th of March Frederick left Berlin for Silesia. Stopping to examine some of his works at Glogau and Breslau, he reached Neisse on the 23d. On the 29th he dismissed the Old Dessauer, with many expressions of kindness and sympathy, to go home to recover his health.

“Old Leopold is hardly at home at Dessau,” writes Carlyle, “when the new Pandour tempests, tides of ravaging war, again come beating against the Giant Mountains, pouring through all passes, huge influx of wild riding hordes, each with some support of Austrian grenadiers, cannoniers, threatening to submerge Silesia. Precursors, Frederick need not doubt, of a strenuous, regular attempt that way. Hungarian majesty’s fixed intention, hope, and determination is to expel him straightway from Silesia.”[81]

The latter part of April Prince Charles had gathered a large force of Austrian regulars at Olmütz, with the manifest intention of again invading Silesia. The King of Poland had entered into cordial alliance with Austria, and was sending a large army of Saxon troops to co-operate in the enterprise. Frederick’s indignation was great, and his peril still greater. Encamped in the valley of the Neisse, assailed on every side, and menaced with still more formidable foes, he dispatched orders to the Old Dessauer immediately to establish an army of observation (thirty thousand strong) upon the frontiers of Saxony. He was to be prepared instantly, upon the Saxon troops leaving Saxony, to ravage the country with the most merciless plunderings of war.

The Queen of Hungary had purchased the co-operation of the Polish king by offering to surrender to him a generous portion of Silesia after the province should have been reconquered. Indeed, there was a great cause of apprehension that the allied army would make a rush upon Berlin itself. The aspect of his Prussian majesty’s affairs was now gloomy in the extreme.

Frederick wrote to his minister Podewils in Berlin, under date of Neisse, March 29, 1745, as follows: “We find ourselves in a great crisis. If we don’t by mediation of England get peace, our enemies from different sides will come plunging in against me. Peace I can not force them to. But if we must have war, we will either beat them, or none of us will ever see Berlin again.”

On the 17th of April again he wrote, still from Neisse: “I toil day and night to improve our situation. The soldiers will do their duty. There is none among us who will not rather have his back-bone broken than give up one foot-breadth of ground. They must either grant us a good peace, or we will surpass ourselves by miracles of daring, and force the enemy to accept it from us.”

On the 20th of April he wrote: “Our situation is disagreeable, but my determination is taken. If we needs must fight, we will do it like men driven desperate. Never was there a greater peril than that I am now in. Time, at its own pleasure, will untie this knot, or destiny, if there is one, determine the event. The game I play is so high, one can not contemplate the issue with cold blood. Pray for the return of my good luck.”

The alarm in Berlin was very great. The citizens were awake to the consciousness that there was danger; that the city itself would be assaulted. Great was the consternation in the capital when minute directions came from Frederick respecting the course to be pursued in the event of such a calamity, and the places of refuge to which the royal family should retreat.

On the 26th of April Frederick again wrote to M. Podewils: “I can understand how you are getting uneasy at Berlin. I have the most to lose of you all, but I am quiet and prepared for events. If the Saxons take part in the invasion of Silesia, and we beat them, I am determined to plunge into Saxony. For great maladies there need great remedies. Either I will maintain my all or else lose my all. To me remains only to possess myself in patience. If all alliances, resources, and negotiations fail, and all conjunctures go against me, I prefer to perish with honor rather than lead an inglorious life, deprived of all dignity. My ambition whispers me that I have done more than another to the building up of my house, and have played a distinguished part among the crowned heads of Europe. To maintain myself there has become, as it were, a personal duty, which I will fulfill at the expense of my happiness and my life. I have no choice left. I will maintain my power, or it may go to ruin, and the Prussian name be buried under it. If the enemy attempt any thing upon us, we will either beat them, or will all be hewed to pieces for the sake of our country and the renown of Brandenburg. No other counsel can I listen to. Perform faithfully the given work on your side, as I on mine. For the rest, let what you call Providence decide as it likes. I prepare myself for every event. Fortune may be kind or be unkind, it shall neither dishearten me nor uplift me. If I am to perish, let it be with honor, and sword in hand.”

Frederick was, with great energy, gathering all his resources for a decisive conflict in his fortresses along the banks of the Neisse. By almost superhuman exertions he had collected an army there of about seventy thousand men. The united army of Austria and Saxony marching upon him amounted to one hundred thousand regulars, together with uncounted swarms of Pandours sweeping around him in all directions, interrupting his communications and cutting off his supplies.
