“Gentlemen, I do not look upon you as my subjects, but as my friends. The troops of Brandenburg have always signalized themselves by their courage, and given, on different occasions, the fullest evidences of their bravery. I shall be an eye-witness to all your exploits. You will always fight in my presence. I will recompense those who shall distinguish themselves for their zeal in my service rather as a father than as a sovereign.”

In reference to this campaign the king subsequently wrote: “At the death of the emperor there were but two Austrian regiments in Silesia. Being determined to assert my right to that duchy, I was obliged to make war during the winter, that I might make the banks of the Neisse the scene of action. Had I waited till the spring, what we gained by one single march would certainly have cost us three or four difficult campaigns.”[44]

To the summons which Frederick sent to Maria Theresa, demanding the surrender of Silesia, no response could be returned, consistent with the dignity of the crown, but a peremptory refusal. The reply was unanswerable in its logic. Though it was, in general, couched in courteous terms, one sentence crept into it of rather scornful defiance.

“It seems strange,” said the Austrian minister of war, “that his Prussian majesty, whose official post in Germany, as chamberlain of the emperor, is to present the basin and towel to the house of Austria, should now presume to prescribe rules to it.”

On Tuesday night, the 12th of December, 1740, there was a very splendid masked ball in Berlin. The king and queen were both present. The mind of the king was evidently preoccupied, though he endeavored to assume an air of gayety. Privately quitting the ball at a late hour, he set out, early in the morning, to place himself at the head of forty thousand troops whom he had assembled near the Silesian frontier. A small escort only accompanied him. It was a cold winter’s day. Driving rapidly, they reached Frankfort that night, sixty miles distant. In the dawn of the next day the king was again upon the road, and, after a drive of forty miles, reached Crossen, a border town, where he established his head-quarters.

Two Silesian barons called upon him, and presented a protest from the authorities they represented against his meditated invasion, the design of which was now manifest to all. The king received them very courteously, tossed the protest to a secretary to file away or to cast into the waste-paper basket, and invited the two gentlemen to dine with him.

The next day the Prussian army, in two divisions, occupying a space about ten miles long and ten broad in the lines of march, crossed the frontiers, and entered the Silesian territory.[45] Frederick issued a proclamation declaring that he had come as a friend; that no one would be molested in person, property, or religious privileges; and that every thing used by the army would be amply paid for.

In very rapid march, the troops advanced through Grünberg toward Glogau, about forty miles in the interior. Here there was a fortified town, which was considered the key of Northern Silesia. It was but feebly garrisoned, and was entirely unprepared for resistance. By great exertions, the Austrian governor of the province, Count Wallis, and his second in command, General Browne, succeeded in placing behind the works a little garrison of one thousand men. The whole population was summoned to work upon the ramparts. Count Wallis remained in Glogau. General Browne took command of the troops and garrisons abroad. But there was a division of sentiment within the walls. Quite a large portion of the population was Protestant, and would be glad to come under the protection of Protestant Prussia. The Catholics were zealous for the continued reign of Austria.

The Prussian troops, meeting with no opposition, spread over the country, and a strong division reached Weichau on Saturday, the 17th. There they spent Sunday in rest. Frederick was anxious to win to his cause the Protestant population. He consequently favored their religious institutions, and ordered that Protestant worship should be held in the villages which he occupied, and where there was no Protestant church edifice, one part of the day in the Catholic churches. This plan he continued through the campaign, much to the gratification of the chaplains of his regiments and the Protestant community in Silesia. Though the Austrian government had not been particularly oppressive to the Protestants, still it leaned decidedly against what it deemed heresy. The Jesuits, favored by the governmental officials, were unwearied in their endeavors to promote the interests of their Church. Frederick, by allowing the impression to be spread abroad that he was the champion of Protestantism, was enabled to secure the sympathies of quite a strong party in Silesia in his favor. It is said that two thirds of the inhabitants of Silesia were Protestants, and therefore favorable to Frederick.
