Such was the Prussian account of the origin of the Second Silesian War.

Frederick again resorted to the method of simultaneous parley and stroke which had served so well when he seized Silesia. On the same day (August 7, 1744) that his ambassador at Vienna announced his crusade to rescue the Emperor, he himself astonished the Saxons by showing them the Emperor’s order to permit the passage of Prussian troops. It is characteristic of the tangled politics of the time that Prussia and Saxony remained technically at peace with each other while Frederick, as the Emperor’s servant, led sixty thousand men up the Elbe into Bohemia and Augustus, as the ally of the Queen of Hungary, sent twenty thousand men to act against him. For the moment Frederick profited by his speed. At the beginning of September he lay before Prague and joined forces with twenty thousand men whom Schwerin had brought from Silesia. Eighty thousand Prussians were thus assembled in the heart of Bohemia, and on September 16th they took the capital.

The appearance of success was, however, delusive. Far from being panic-stricken by Frederick’s sudden spring, the scrupulous Queen rejoiced to see him break the treaty which gave him a title to Silesia. From every point of the compass she summoned forces to defend Bohemia. The army of Alsace recrossed the Rhine with great skill and marched eastwards. They were undisturbed by the French, among whom Frederick’s treacheries were passing into a proverb:—se battre pour le roi de Prusse, to fight without reward. Clouds of irregular horse issued from Hungary. The Saxons were marching southwards. The people of Bohemia showed themselves hostile to the Prussians and assisted an Austrian army to maintain itself in the kingdom. What course, we may ask, was the wisest for a commander surrounded by so many dangers?

After the fall of Prague Frederick lay in the centre of Bohemia, a kingdom walled in by a quadrilateral of mountains. He held the north-eastern gates which led into Silesia. The south-western led into Bavaria, and through them the army of Alsace was soon to enter. But at the head of nearly 80,000 men the King was vastly stronger than any single force that could be brought against him and his communications with Prussia were safe. There was therefore much to be said for a simple defensive policy. North-eastern Bohemia was the prize that Frederick hoped to gain by the war, and this he could have held like a second Silesia. Such a desertion of his allies would, however, have shocked public opinion, particularly in France, and Frederick admits that he shrank from it on that account.

The next best course, if some offensive movement must be made, would have been first to crush the army of Bohemia and then to hold the south-western gate against the army of Alsace. This course was advised by Schwerin and favoured by the King. But the fatal influence of Belleisle proved stronger than the promptings of common-sense. France was avenged for the treacheries of Klein Schnellendorf and Berlin when Frederick allowed himself to be persuaded to strike due south, in the hope of conquering Bohemia, opening communications with Bavaria, and cowing Vienna.

At first the plan prospered. Several towns were captured for the Emperor, and by October 4, 1744, the Prussians had almost reached the frontier of Austria proper. Then they began to realise that they were the dupes of a mirage. The armies of Bohemia and of Alsace had united in their rear and lay between them and Prague. They found themselves isolated, ill fed, and worse informed. Swarms of light horse enveloped them, cutting off convoys, scouts, and messengers. Schwerin opened a line of retreat, but their recent conquests were lost with the garrisons which held them. The Austrians had found a soldier, Field-marshal Traun, and at his hands Frederick received painful lessons in the art of war. The King had already begun to negotiate. He thirsted for French co-operation and a pitched battle, but could obtain neither boon. Traun, who was now superior in numbers, had no need to fight. He occupied unassailable positions to the north of Frederick’s force and left hunger, disease, and irregulars to do their work upon the enemy. Thus harassed, the Prussian rank and file deserted by thousands, and many offered their services to Traun. Schwerin again took umbrage and withdrew from the campaign.

FREDERICK THE SECOND, KING OF PRUSSIA.

AFTER THE PAINTING BY F. BOCK.

Step by step the reluctant King was driven towards Silesia. Before the end of November it was plain that his whole enterprise must be abandoned. It was mid-December before the last detachments of some 40,000 men, the remnant of his 80,000, straggled across the mountains to the friendly walls of Glatz. Thanks to the determination of Maria Theresa, a postscript had yet to be added to the history of the campaign. In the spirit of her own Hungarians, who scorned to provide a commissariat because their forefathers had journeyed from Asia to the Land of the Five Rivers without one, the Queen dictated a winter assault upon Silesia. The Old Dessauer, whom Frederick had left in command, at length succeeded in clearing the province of anything like an Austrian army, but it was not till February that the Prussians were able to go into winter quarters. Thus a campaign which had begun with the conquest of Bohemia came to an end to the sound of Te Deums sung at Berlin for the deliverance of Silesia. Europe began to suspect that the sword of Traun had pricked the Prussian bubble.
